Slippery flooring can become a serious safety concern when surfaces are exposed to water, oil, grease or other contaminants. Anti-Slip GRP Flat Sheets are designed to introduce a highly effective high-grip surface to existing flooring, helping provide safer footing across a wide range of conditions.

The sheets feature a resin-coated gritted surface that provides excellent traction underfoot. The aggressive texture helps maintain contact with footwear, even when the surface is wet or contaminated, making the sheets suitable for areas where ordinary smooth flooring may not provide sufficient grip.

Tested Slip Resistance

The anti-slip performance has been tested to BS 7976.2, with Pendulum Test Values (PTV) indicating 'Extremely Low' slip potential in wet and dry conditions and 'Low' slip potential in oily and greasy conditions.

The tested coefficient of friction (CoF) values are:

• Dry: 73
  
• Wet: 72
  
• Oil: 63

These results demonstrate the strong level of traction provided by the gritted GRP surface across different conditions.

Designed for Demanding Foot Traffic

Anti-slip flooring needs to maintain its performance as well as provide initial grip. These GRP Flat Sheets have an excellent wear-resistance rating of Level 3 and are suitable for areas subject to heavy footfall.

They are also suitable for wheeled areas, making them useful where pedestrians and wheeled traffic share the same access route.

Good to Know:

A slip-resistant surface is only one part of an effective safety strategy. Dirt, oil and other contaminants should still be removed regularly, as excessive contamination can affect the performance of any walking surface.

From the Mats4U Team

When we're assessing an anti-slip flooring solution, we like to see actual test results rather than relying solely on phrases such as “high grip” or “heavy duty”. The BS 7976.2 testing and CoF results give you useful information about how the GRP surface performs in dry, wet and oily conditions, making it easier to assess whether it is appropriate for your particular environment.

One of the main advantages of Anti-Slip GRP Flat Sheets is that they can be installed directly onto suitable existing surfaces. Rather than removing and replacing an entire floor, the GRP sheet can provide a new high-grip surface over substrates such as concrete, metal and wood.

This makes the sheets particularly useful when the existing structure is still sound but the walking surface has become worn, smooth or insufficiently slip resistant. Applying an anti-slip GRP overlay can provide a practical way to improve the surface without undertaking a much larger flooring replacement project.

A Low-Profile Flooring Solution

At just 4mm thick, the GRP Flat Sheet provides an anti-slip surface without adding substantial height to the existing floor. This low-profile construction can be particularly useful around access routes, thresholds and other areas where changes in floor level need to be kept to a minimum.

The sheets can be cut to length and size, allowing them to be adapted to individual areas rather than relying entirely on fixed sheet dimensions. This makes it possible to cover specific high-risk sections or create defined anti-slip routes across a larger surface.

Suitable for More Than Complete Floor Coverage

The sheets don't necessarily need to cover an entire room or floor. They can be used selectively where additional traction is needed, including:

• Walkways and designated access routes.
  
• Platforms and working areas.
  
• Ramps.
  
• Existing flooring.
  
• Stair covers.
  
• Bridges and access points.

They can also be used to mark out walkways and provide visually defined access routes, with Black, Grey and Yellow options available depending on the required finish.

Things to Consider:

Before installation, the existing substrate should be suitable, sound and appropriately prepared for the chosen fixing method. The GRP sheet provides the anti-slip surface, but the condition of the underlying substrate remains important to the overall performance of the installation.

From the Mats4U Team

If you're dealing with an existing floor that is structurally fine but has become slippery, we'd always ask whether the whole surface really needs replacing. An anti-slip GRP overlay can be a much less disruptive approach, particularly when only specific walkways, ramps or working areas need improved traction.

Anti-Slip GRP Flat Sheets are manufactured from Glass Reinforced Polyester (GRP), combining fibreglass reinforcement with a durable resin system to create a strong, hard-wearing surface.

The 4mm sheets are designed to withstand demanding everyday use, with an excellent wear-resistance rating of Level 3 and suitability for areas exposed to heavy footfall. The material is also impact resistant, helping it cope with the knocks and general wear associated with busy working environments.

Resistant to Water, Oil & Chemicals

GRP provides excellent resistance to many of the conditions that can cause other flooring materials to deteriorate. These flat sheets are resistant to water, oil, chemicals and corrosion, making them suitable for environments where regular exposure to moisture or contaminants is unavoidable.

The sheets also have a very low water absorption rate, with testing to ISO 62 recording just 0.4% water absorption. This helps explain why GRP is well suited to wet environments where maintaining a stable, durable surface is important.

Suitable for Indoor & Outdoor Use

Anti-Slip GRP Flat Sheets are suitable for both indoor and outdoor applications. They have been tested for UV resistance and are designed to withstand temperatures from approximately -50°C to +110°C.

This combination of environmental resistance and mechanical strength allows the sheets to be used in areas where flooring may be exposed to changing weather conditions, moisture, chemicals, heavy traffic and general industrial wear.

Good to Know:

GRP is resistant to corrosion, but that doesn't mean every substance is automatically harmless to the material. If the sheet will be exposed to particularly aggressive chemicals, we recommend checking compatibility with the specific substance before installation.

From the Mats4U Team

When choosing an anti-slip surface, we think it's important to look beyond the grip itself. A product may perform well initially, but the real question is whether the material can continue performing in the environment where it's being installed. The combination of wear resistance, low water absorption, chemical resistance and UV resistance makes GRP a particularly practical material for demanding flooring applications.

Anti-Slip GRP Flat Sheets are available in a range of standard sizes, but they can also be cut to length and size to suit individual project requirements. This makes them suitable for covering specific areas, creating defined walkways or fitting around existing features where a standard sheet may not provide the required dimensions.

The ability to cut the material makes it easier to achieve a neat, close-fitting installation without having to use an entire standard sheet for every application.

Flexible Fixing Options

Depending on the substrate and installation requirements, screws and adhesive are available separately. This provides flexibility when deciding how the GRP sheet should be secured to the existing surface.

The most appropriate fixing method will depend on factors such as the substrate, expected traffic, environmental conditions and whether the installation needs to withstand wheeled or heavy use. The underlying surface should always be properly prepared before installation.

Designed to Minimise Disruption

The straightforward design of the sheets means installation can generally be completed without the extensive preparation associated with replacing an entire floor. This can help reduce downtime and disruption, particularly where the existing substrate is suitable and only the surface performance needs to be improved.

For larger projects, sheets can also be planned and cut around the layout of the area before installation, helping create a consistent and professional finish.

Please note that the manufacturer's stated cutting tolerance is ±3mm, so this should be taken into account when planning bespoke cuts.

Top Tip:

Measure the area carefully before cutting. Where several sheets are being installed together, allow for the exact dimensions of the substrate and plan the sheet layout beforehand. This can help minimise unnecessary cuts and material waste.

From the Mats4U Team

For a bespoke installation, we'd recommend planning the layout before ordering or cutting the sheets. It's much easier to work out where joins, edges and fixing points will fall while you have the whole area in front of you. A little preparation at this stage can make the actual installation considerably quicker.

Anti-Slip GRP Flat Sheets can be used wherever an existing walking or working surface needs additional traction. Their low-profile construction and ability to be cut to size make them suitable for covering specific areas without requiring a complete flooring replacement.

They can be used across a wide range of environments, from everyday pedestrian access routes to demanding industrial and construction applications.

Create Clearly Defined Access Routes

The sheets can be used to create dedicated walkways and access routes, helping distinguish pedestrian areas from surrounding surfaces. Yellow sheets can provide a particularly visible finish where increased visual definition is desirable, while Black and Grey offer more understated alternatives.

This makes the product useful not only for improving traction but also for helping organise how people move through a space.

Suitable for Pedestrian & Wheeled Traffic

The durable GRP construction is suitable for both pedestrian and wheeled areas, making the sheets versatile enough for locations where different types of traffic use the same route.

They can be specified for applications including:

• Industrial and manufacturing environments.
  
• Construction sites.
  
• Commercial premises.
  
• Schools and educational facilities.
  
• Residential areas.
  
• Sports and leisure facilities.
  
• Bridges and access structures.

The sheets are suitable for both wet and dry areas and can be used where exposure to oil, grease or other contaminants is expected.

Things to Consider:

Think about how the space is actually used before choosing the sheet size and colour. A walkway used primarily by pedestrians may have different requirements from an area regularly used by wheeled equipment or exposed to heavy industrial traffic.

From the Mats4U Team

We particularly like the versatility of a flat GRP sheet because you're not restricted to one type of installation. The same basic product can be used to improve a walkway, cover a slippery ramp, define an access route or provide additional grip across an existing working surface. The key is matching the sheet and fixing method to the environment rather than treating every application the same way.

Anti-Slip GRP Flat Sheets are designed to be straightforward to clean and maintain, even in areas where dirt, dust and other contaminants are regularly brought onto the surface.

For everyday cleaning, a stiff brush will normally be enough to remove loose dirt and debris from the gritted surface. For more stubborn contamination, the sheets can be washed with warm water and a mild detergent.

Where appropriate, a pressure washer can also be used on a low-pressure setting to remove more persistent dirt. This can be particularly useful on larger installations or outdoor areas where mud and debris may accumulate.

Keeping the Anti-Slip Surface Performing

Regular cleaning is important wherever the sheets are exposed to oil, grease, mud or other contaminants. Although the gritted GRP surface provides excellent slip resistance, allowing contamination to build up can affect the performance of any anti-slip flooring.

The material itself requires relatively little ongoing maintenance. Its resistance to water, corrosion, chemicals and UV exposure means there is no requirement for the type of protective treatment that some traditional flooring materials may need.

Top Tip:

Cleaning requirements will depend on the environment. A lightly used indoor walkway may only need occasional cleaning, while an outdoor or industrial installation exposed to mud, oil or heavy traffic may benefit from a more frequent cleaning routine.

From the Mats4U Team

We'd keep maintenance simple: remove loose debris regularly, deal with oil or other contamination promptly and use the least aggressive cleaning method that gets the job done. Looking after the gritted surface properly helps maintain the traction that the GRP sheet was installed to provide in the first place.

When adding an anti-slip surface to an existing floor, the thickness of the material can be just as important as its grip. At 4mm thick, Anti-Slip GRP Flat Sheets provide a relatively low-profile solution that can improve surface traction without creating a substantial change in floor level.

This makes them suitable for applications where people need to move easily between treated and untreated areas, including routes used by pedestrians and wheeled traffic.

Suitable for Wheeled Access

The flat profile and durable construction make the sheets suitable for wheeled areas, including routes used by wheelchairs and other wheeled equipment. Their ability to be cut to size also allows the anti-slip surface to be installed across defined access routes rather than requiring an entire floor to be covered.

As with any flooring solution, the underlying surface should be appropriately prepared and the finished installation should be assessed as a complete access route. Transitions between different surfaces should be kept as practical and safe as possible.

Use Colour to Define Access Areas

Anti-Slip GRP Flat Sheets are available in Black, Grey and Yellow, providing options for both discreet installations and more visually prominent applications.

Yellow can be particularly useful where the anti-slip surface also needs to help identify a walkway, access route or other designated area. Black and Grey can provide a more subtle finish where the priority is improving the surface without creating a strong visual contrast.

Using colour deliberately can help distinguish different areas of a site and make designated routes easier to identify.

Good to Know:

Colour can support visual identification, but it should not be treated as a replacement for appropriate signage, site markings or other safety measures where these are required.

From the Mats4U Team

When we're looking at an anti-slip flooring project, we don't think safety should stop at the grip rating. Consider how people actually move across the area, whether wheeled access is required and whether different zones need to be visually distinguished. A well-planned installation should make the route safer without creating a new obstacle or access issue.

What is the difference between a GRP Flat Sheet and a GRP Grating Stair Tread?

A GRP Flat Sheet is a solid 4mm anti-slip sheet designed to be installed over an existing surface. A GRP Grating Stair Tread has an open grating construction designed specifically for stairways, allowing water and debris to pass through the tread. The right choice depends on the application and whether drainage through the surface is required.

Buying Advice:

When specifying an Anti-Slip GRP Flat Sheet, consider the condition of the existing substrate, the type of traffic, expected contamination, required sheet dimensions and the fixing method before ordering. These factors will help determine whether a GRP overlay is the right solution for the application.

From the Mats4U Team

If you're looking at GRP because an existing surface has become slippery, we'd recommend looking at the whole installation rather than simply the area that feels unsafe. Consider where people walk, how the surface gets contaminated, whether wheeled access is required and how the sheet will be fixed. Getting those details right at the planning stage can make the finished anti-slip installation considerably more effective.
