Standard Configurations

GRP Step Over Platforms are currently available in a range of platform dimensions and clearance heights.

Standard clearance options include:

• 100mm
  
• 150mm
  
• 200mm

Standard platform dimensions include configurations from approximately 464 × 996mm through to 1220 × 1220mm, depending on the selected model.

Exact dimensions and weights are shown against each individual product option. Bespoke sizes can also be considered where standard configurations do not meet the requirements of the installation.

Good to Know: The Step Over Platform is a combined system rather than a single piece of GRP. Its performance comes from the grating, structural U Profile and stair nosing working together, so the complete platform should be assessed when specifying it for a particular application.

From the Mats4U Team

 The technical figures are useful when comparing products, but we'd always look at them alongside the actual installation requirements. If you need a platform for a specific obstacle, send us the dimensions, expected use and surrounding conditions and we can help you identify the most appropriate standard or bespoke configuration.

Create a Safer Route Over Pipes, Cables & Equipment

Pipes, cables, conduits and other low-level obstacles can be difficult to avoid in busy working environments. Asking people to step over them informally can create an inconsistent and potentially hazardous access route, particularly where the obstacle is located along a frequently used walkway.

A GRP Step Over Platform provides a clearly defined crossing point. Instead of stepping directly over the obstruction, users step onto the raised platform, cross over the obstacle and step down on the other side.

This creates a more deliberate and predictable way of navigating around obstacles while keeping the existing pipework, cabling or equipment in place.

A Defined Crossing Point

The raised platform creates a visible and physical distinction between the normal walking surface and the area where an obstacle is being crossed. This can help users recognise that there is a change in level and adjust their footing accordingly.

The yellow stair nosing provides additional visual contrast along the platform edges, helping make the step location more obvious to approaching users.

This is particularly useful in busy areas where people may be moving around while carrying equipment, handling materials or concentrating on other tasks.

Avoid Unnecessary Changes to Existing Infrastructure

Removing or relocating pipework, cables and equipment is not always practical. Infrastructure may be expensive to move, essential to the operation of a facility, or positioned where alteration would create additional work.

A step-over platform can provide an alternative access solution by allowing the existing obstruction to remain in place while creating a dedicated route above it.

This can be useful when improving access around existing installations without undertaking major structural changes.

Good to Know:

A step-over platform should not be used simply because an obstacle is present. The height and dimensions of the obstruction, available space around it, frequency of use and requirements of the people using the route should all be considered when selecting the appropriate platform.

Make Access More Predictable

A clearly defined crossing point can also help establish a consistent route through an area. Rather than having people choose where and how to step over an obstacle, the platform provides a designated place to cross.

The result is a more structured access arrangement that can be incorporated into a wider workplace walkway or access system.

Top Tip: Think about the approach to the platform as well as the platform itself. Users need enough clear space to reach the step-over point comfortably, place their feet securely and continue their route once they have crossed the obstacle.

From the Mats4U Team

We'd always recommend looking at the wider access route when installing a Step Over Platform. The platform solves the immediate problem of getting over the obstacle, but good access planning also considers what happens before and after the crossing. A clear approach and enough room to use the platform comfortably can make a significant difference to how effective the finished solution is.

Make the Change in Level Easier to See

A Step Over Platform introduces a change in level to an otherwise continuous walking route. Making that change clearly visible is therefore an important part of the overall design.

GRP Step Over Platforms feature yellow stair nosing along the platform edges, providing a strong visual contrast against the grey grating. This helps draw attention to the step and gives approaching users a clear indication that the walking surface is changing.

The high-visibility edging is particularly useful in busy working areas where the platform needs to be quickly identifiable as part of the access route.

Resin-Coated Gritted Surface for Reliable Traction

The walking surface is manufactured from GRP grating with a resin-coated gritted finish. The textured surface is designed to provide strong underfoot traction, helping users maintain their footing when stepping onto, across and off the platform.

The grating has been tested to BS 7976.2, achieving a Pendulum Test Value (PTV) of 72 in dry conditions, 68 in wet conditions and 63 in oily conditions. The stated classifications are Extremely Low slip potential for wet and dry conditions and Low slip potential for oily and greasy conditions.

Designed for Wet & Oily Conditions

Step-over platforms may be positioned in areas where water, oil or other contaminants are present. A smooth walking surface can become less suitable when contaminated, which is why the textured GRP surface is an important part of the platform's design.

The gritted finish provides a mechanical texture underfoot rather than relying on a completely smooth surface, helping maintain traction across a range of conditions.

Good to Know: Slip resistance testing provides useful information about the surface performance, but the actual conditions on site still matter. Contamination, footwear, cleaning, platform position and the surrounding access route can all influence how safely a platform is used.

A Clearer Step-Up and Step-Down Point

The combination of the textured walking surface and contrasting yellow nosing addresses two different aspects of using a step-over platform: grip and visibility.

The gritted surface helps provide traction underfoot, while the yellow edging makes the platform's boundaries and changes in level more apparent. Together, these features help create a more clearly defined crossing point over the obstacle.

From the Mats4U Team

We'd pay particular attention to the edges of any step-over solution. Users need to recognise where they're stepping up and stepping down, especially when approaching from a busy walkway. The contrasting yellow nosing is a simple but useful feature that makes those transition points much easier to identify.

Install Without Permanent Anchoring

GRP Step Over Platforms are designed as free-standing access solutions, meaning they do not require permanent anchoring to the floor simply to provide a route over a suitable low-level obstruction.

This makes them useful where the surrounding layout needs to remain flexible or where a permanent structural alteration is not desirable. The platform can be positioned over the obstacle and used as a dedicated crossing point without becoming a fixed part of the building or floor.

Reposition When Access Requirements Change

Workplaces, production areas and industrial sites do not always remain laid out in the same way. Machinery can be moved, temporary equipment introduced and pipework or cables altered as operations change.

A free-standing platform can provide greater flexibility in these situations. Where the installation allows it, the platform can be repositioned to suit a revised access route rather than requiring a new permanent structure.

This can be particularly useful for temporary works, changing work areas or locations where obstacles may only be present for a particular period.

Standalone or Part of a Larger Access System

The Step Over Platform can be used independently as a single crossing point or incorporated into a wider access arrangement.

For example, a platform can form one part of a larger walkway or access system where users need to cross several obstacles or navigate around existing infrastructure. This allows the step-over solution to be considered as part of the overall route rather than as an isolated product.

Lightweight Without Sacrificing Stability

The GRP construction provides a useful combination of strength and relatively low weight. This makes the platform easier to handle and position while retaining the rigid construction required for a stable walking surface.

The different clearance heights also allow the platform to be selected according to the obstacle it needs to cross, rather than using one fixed configuration for every situation.

Good to Know: "Free-standing" does not mean that every platform is suitable for every location without further consideration. The platform should be positioned on a suitable, stable and reasonably level surface, with the obstacle and surrounding area assessed to ensure the finished access route is appropriate.

Choose the Clearance Height Around the Obstacle

The available platforms include different clearance heights to accommodate obstacles of varying dimensions. Current standard options provide approximately 100mm, 150mm and 200mm clearance, depending on the selected model.

Where a standard configuration does not provide the required dimensions, bespoke options can be considered.

From the Mats4U Team

 Before choosing a platform, measure the obstacle at its highest point and consider whether anything around it could affect the platform's position. We'd also allow sensible clearance rather than selecting a platform that only just fits over the obstruction. If the required dimensions fall outside the standard options, ask us about a bespoke solution before ordering.

Built from Glass Reinforced Polyester

The Step Over Platform is constructed from high-quality Glass Reinforced Polyester (GRP) grating, U Profile and anti-slip stair nosing. This composite construction provides the strength and durability required for regular pedestrian access while avoiding many of the maintenance concerns associated with traditional metal structures.

The GRP components feature resin-coated gritted surfaces, creating a hard-wearing platform designed for continued use in demanding environments.

Resistant to Corrosion & Harsh Chemicals

GRP is naturally resistant to rust and corrosion, making it particularly useful where a platform may be exposed to moisture, chemicals or changing environmental conditions.

The material is also identified as chemical resistant, allowing the Step Over Platform to be considered for industrial environments where exposure to aggressive substances may be part of normal operations.

Unlike steel, GRP does not develop conventional surface rust when exposed to moisture, helping maintain the integrity and appearance of the platform over time.

Designed for Indoor & Outdoor Conditions

The Step Over Platform is suitable for both indoor and outdoor use. It is UV resistant and has a stated temperature resistance of -50°C to +110°C, allowing it to be used across a wide range of environmental conditions.

Its resistance to impact, chemicals and weathering makes it suitable for locations where a standard indoor access product may not provide the required durability.

Non-Conductive GRP Construction

Another important characteristic of GRP is that it is non-conductive. The Step Over Platform is identified as suitable for electrical and high-voltage electrical environments, making GRP a useful alternative to conductive metal access structures where electrical considerations form part of the site requirements.

The specific electrical requirements of the installation should always be assessed before selecting the product.

Designed for Regular Use

The GRP grating has Level 3 excellent wear resistance and is rated as suitable for heavy footfall. Combined with its impact resistance and durable construction, this makes the platform suitable for regular pedestrian access rather than being limited to occasional use.

Good to Know: GRP's resistance to corrosion is one of its key advantages in demanding environments. However, the surrounding fixings, supporting surface and any additional components should also be selected with the conditions of the installation in mind.

From the Mats4U Team

If a step-over platform is going to spend years in a wet, outdoor, industrial or chemically demanding environment, we'd consider the material just as carefully as the platform dimensions. GRP gives you a combination of corrosion resistance, durability and relatively low weight that can make it a particularly practical choice where traditional metal access systems may require more maintenance.

Match the Platform to the Obstacle

Selecting the correct Step Over Platform starts with the obstacle that needs to be crossed. The platform must provide sufficient clearance above pipes, cables, ducts or equipment while also providing enough walking surface for users to step onto, cross and step down safely.

Measuring the obstacle before ordering is therefore essential. Consider its height, width and position, as well as anything nearby that could affect how the platform sits.

Choose the Appropriate Clearance Height

GRP Step Over Platforms are available with different clearance heights to accommodate obstacles of varying sizes.

Standard options currently include:

• 100mm clearance
  
• 150mm clearance
  
• 200mm clearance

The overall platform height varies accordingly, so it is important to check the individual product dimensions rather than selecting a model based on clearance height alone.

Consider the Walking Surface

The platform dimensions determine how much space users have when stepping onto and across the obstacle. Wider and longer platforms may be more appropriate where there is greater available space or where the access route needs to accommodate a larger crossing area.

Current standard configurations include platform widths and lengths ranging from approximately 464mm × 996mm through to 1220mm × 1220mm, depending on the model.

Exact dimensions and weights are shown against each individual product option.

Bespoke Platforms for Unusual Requirements

Standard sizes will suit many installations, but not every obstacle or access route will conform to a standard configuration.

Bespoke Step Over Platforms can be produced where different dimensions are required. This can be useful when working around existing infrastructure, restricted spaces or larger obstacles where a standard platform may not provide the required clearance or walking area.

Good to Know: Don't measure only the obstacle itself. Allow for the space users need to approach the platform, step onto it, cross over the obstruction and step down again. The surrounding area is just as important as the dimensions of the obstacle.

Think About the Complete Route

The platform should form part of a safe and practical access route. Check that there is adequate space on both sides of the platform and that the approach is not obstructed by additional pipework, machinery, stored materials or other hazards.

Where several obstacles are present, consider whether individual step-over platforms or a larger integrated access system would provide the more practical solution.

Top Tip: When requesting a bespoke platform, provide the obstacle dimensions as accurately as possible, along with the required overall platform length and width. If you're unsure which clearance height or configuration you need, sharing photographs and measurements with us can help us understand the installation more clearly.

From the Mats4U Team

 We'd always recommend measuring twice before ordering a step-over platform. The most important measurements are the height of the obstacle, the available space around it and the amount of walking surface required. If those three things are clear, choosing the right platform configuration becomes much easier.

A Practical Access Solution with Minimal Disruption

GRP Step Over Platforms are designed to provide an immediate route over suitable low-level obstacles without requiring major alterations to the surrounding infrastructure.

Because the platform is free-standing, it can be positioned over the obstruction and incorporated into an existing access route with relatively little disruption. This can be particularly useful where pipework, cables or equipment cannot easily be moved.

Easy to Handle and Position

The GRP construction keeps the platform relatively lightweight while maintaining a rigid and durable structure. This makes the individual units easier to handle and position than many heavier traditional access structures.

The practical installation process can also reduce the need for extensive specialist tooling, although the exact requirements will depend on the installation and whether the platform is being used as a standalone unit or as part of a larger system.

Integrate with a Wider Access Arrangement

A Step Over Platform does not have to operate in isolation. It can form part of a wider access system where users need to navigate around existing infrastructure.

For example, a platform can be incorporated into a planned route alongside walkways, ramps or other GRP access components. This can help create a more continuous and deliberately designed route through areas containing multiple obstacles.

Consider the Surface Beneath the Platform

Although the platform is free-standing, the surface supporting it remains important. It should be positioned on a suitable, stable and reasonably level area so that the platform can sit securely during normal use.

The surrounding surface should also be checked for additional trip hazards or uneven areas that could undermine the effectiveness of the access route.

Good to Know: A free-standing platform can be easier to install and reposition, but it still needs to be properly assessed for the location in which it will be used. The platform, obstacle and surrounding access route should be considered together.

Plan Around Existing Infrastructure

One of the main advantages of a Step Over Platform is that it allows access improvements to be made without necessarily relocating existing infrastructure.

Before installation, consider the position of nearby pipes, cables, machinery, walls and other structures. There should be enough room for users to approach, cross and leave the platform without being forced into another obstruction.

From the Mats4U Team

 We'd recommend planning the route from the user's perspective rather than looking only at where the obstacle is. Stand back and consider where someone will approach from, where they'll place their feet and where they'll go immediately after crossing. That simple check can highlight access issues before the platform is installed.

Easy to Keep the Platform Clear

GRP Step Over Platforms are designed to require relatively straightforward routine maintenance. The textured GRP surfaces can be cleaned using simple methods appropriate to the level of dirt and contamination present.

Regular cleaning helps keep the walking surface clear and allows the yellow nosing and platform edges to remain clearly visible.

Remove Everyday Dirt and Debris

For routine cleaning, a stiff brush can be used to remove loose dirt, dust and debris from the gritted surface and grating.

Because the platform incorporates open GRP grating, loose material can also pass through the openings rather than remaining entirely on the walking surface. However, areas around and beneath the platform should still be inspected periodically where debris could accumulate.

Cleaning More Stubborn Contamination

Where the platform is exposed to mud, oils or other more persistent contamination, warm water and a mild detergent can be used to clean the surface.

The cleaning method should be appropriate to the substance being removed and the conditions of the particular site. Avoid using cleaning products that could adversely affect the GRP or surrounding components.

Inspect the Platform as Part of Routine Site Checks

Cleaning is only one part of maintaining a safe access route. The platform should also be visually inspected from time to time for any signs of damage, movement or deterioration.

Pay particular attention to the grating, nosing, structural components and the surface on which the platform is standing. Any change in the condition of the surrounding obstacle should also be considered.

Good to Know: Because the platform is free-standing, routine checks should include its position and stability as well as the condition of the GRP itself. Site activity can sometimes cause equipment or obstacles around an access route to move.

Keep the Access Route Clear

The platform should not be treated as a solution to every hazard around the obstacle. Stored materials, tools, cables or other objects should not be allowed to obstruct the approach to the platform or the area immediately beyond it.

Keeping the complete route clear helps ensure users can approach, cross and leave the platform as intended.

Top Tip: Include the Step Over Platform in your normal workplace inspection routine. A quick visual check of the surface, yellow nosing, platform position and surrounding access route can help identify problems before they become an issue.

From the Mats4U Team

A GRP platform is designed to be low maintenance, but that doesn't mean it should be forgotten once installed. We'd treat it like any other access equipment: keep it clean, check it regularly and make sure the surrounding route remains clear and suitable for use.

What is a GRP Step Over Platform?

A GRP Step Over Platform is a raised, free-standing access platform designed to provide a safer route over low-level obstacles such as pipework, cables, ducts and equipment. It combines GRP grating, structural U Profile and anti-slip stair nosing.

What obstacles can a Step Over Platform be used to cross?

They can be used to provide access over suitable low-level obstacles including pipes, cables, ducting and equipment. The obstacle's height, width and location should be assessed before selecting a platform to ensure the appropriate clearance and walking area are provided.

Does a GRP Step Over Platform need to be permanently fixed?

The platform has a free-standing design and does not require permanent anchoring simply to provide a crossing over a suitable obstacle. However, the platform must be positioned on an appropriate, stable surface and the complete installation should be assessed for its intended use.

Can the Step Over Platform be moved?

Yes, its free-standing design allows it to be repositioned where the installation and site conditions permit. This can be useful where access routes or the position of temporary obstacles change over time.

What clearance heights are available?

Standard options currently include approximately 100mm, 150mm and 200mm clearance, depending on the selected model. Bespoke configurations can also be considered where a standard clearance is not suitable.

What sizes are available?

There are several standard combinations of platform length and width, ranging from approximately 464 × 996mm to 1220 × 1220mm. Exact dimensions vary by model and are shown against the individual product options.

Can Step Over Platforms be made to a bespoke size?

Yes. Bespoke sizes can be produced to suit individual access requirements. A cutting tolerance of ±5mm applies where applicable.

Are GRP Step Over Platforms suitable for outdoor use?

Yes. They are suitable for both indoor and outdoor environments and are UV resistant. They are also designed to withstand a wide range of temperatures, from -50°C to +110°C.

Are GRP Step Over Platforms suitable for wet areas?

Yes. The GRP grating has a textured resin-coated surface designed to provide traction in wet conditions, while the open grating allows water to pass through rather than collecting across a solid walking surface.

Can they be used in oily or greasy environments?

Yes. The GRP grating and stair nosing have been tested under oily conditions. The grating achieved a PTV of 63 and the stair nosing a PTV of 51 under the stated test conditions.

Are GRP Step Over Platforms resistant to chemicals?

Yes. The GRP components are chemical resistant and designed for demanding environments. Where specific chemicals are involved, compatibility should be assessed against the particular substance and exposure conditions.

Are GRP Step Over Platforms suitable for heavy footfall?

The GRP grating has Level 3 excellent wear resistance and is identified as suitable for heavy footfall. The complete installation should still be assessed according to the expected use, support arrangement and loading requirements.

What is the load rating of the GRP Step Over Platform?

The GRP grating component has been tested to BS EN 124 and classified as Class A15. This should not be treated as a universal load rating for every installation. The supporting structure, span, fixing arrangement and intended loads must also be considered.

Are GRP Step Over Platforms suitable for wheeled traffic?

The GRP grating is identified as suitable for wheeled areas. However, the suitability of a particular Step Over Platform depends on the type and weight of wheeled traffic, wheel configuration, platform support and the complete installation.

Are GRP Step Over Platforms electrically conductive?

No. The GRP components are non-conductive and are identified as suitable for electrical and high-voltage electrical environments. Specific project requirements should always be assessed where electrical safety is a critical consideration.

Why does the platform have yellow nosing?

The yellow nosing provides a strong visual contrast at the platform edges, helping users identify the step-up and step-down points and recognise the change in level more easily.

How do you clean a GRP Step Over Platform?

Routine dirt and debris can normally be removed with a stiff brush. More stubborn contamination can be cleaned using warm water and a mild detergent. A pressure washer may also be used on a low-pressure setting where appropriate.

What is GRP?

GRP stands for Glass Reinforced Polyester. It is a composite material combining fibreglass reinforcement with resin to provide a strong, durable and corrosion-resistant construction.

Can a Step Over Platform be integrated into a larger access system?

Yes. The platform can be used as a standalone crossing point or incorporated into a wider access arrangement alongside other suitable GRP access components.

How do I choose the right Step Over Platform?

Start by measuring the obstacle's height and width, then consider the available space around it and the amount of walking surface required. You should also consider the expected footfall or wheeled traffic, supporting surface and surrounding access route.

Good to Know: Choosing the correct clearance is only part of specifying a Step Over Platform. The complete route needs to be considered, including the approach to the platform, the surface underneath it and the space available after crossing.

From the Mats4U Team

 If you're unsure which configuration you need, send us the obstacle dimensions, photographs of the area and any information you have about how the platform will be used. That gives us a much better starting point for helping you identify the right standard or bespoke solution.
