Good to Know

The technical figures above relate to the stated assessment parameters. The design load range should not be interpreted as the capacity of every installation, as the substrate, anchor spacing, embedment, edge distances and complete structural arrangement all affect performance.

From the Mats4U Team

Keep the anchor's ETA information with your project documentation where structural fixing performance needs to be demonstrated. For projects with specific loading or seismic requirements, the applicable assessment conditions should be checked before installation.

The Rawl ETA Throughbolt Anchor is designed to provide a secure connection between GRP support profiles and concrete. It is particularly relevant when installing GRP Angle Profile or GRP U Profile as part of a grating support structure.

The throughbolt design passes through the component being secured before expanding within the drilled hole in the concrete. This provides a practical method of fixing profiles to a concrete substrate where a structural fastening solution is required.

Suitable for GRP Angle & U Profiles

The anchor is designed to complement our range of GRP profiles, including:

• GRP Angle Profile – used for fastening grating panels and creating frames or support structures
  
• GRP U Profile – designed to provide support around larger openings and voids

Using an appropriate concrete anchor allows these profiles to be securely connected to the supporting structure, helping create a complete fixing arrangement for GRP grating installations.

Suitable for Cracked & Uncracked Concrete

The anchor has been assessed for use in both:

• Cracked concrete
  
• Uncracked concrete

It is also assessed for seismic applications, including C1 and C2 categories within the applicable assessment parameters.

This makes it suitable for a range of demanding construction and infrastructure applications where the concrete substrate and fixing requirements need to be considered carefully.

Good to Know

An anchor's suitability is determined by more than the profile being fixed. Concrete condition, embedment, edge distances, spacing, applied loads and the overall fixing arrangement can all affect the appropriate installation.

From the Mats4U Team

If you're specifying anchors for a GRP grating project, make sure you know the concrete substrate and the loads the fixing arrangement needs to accommodate before selecting the anchor.

The Rawl ETA Throughbolt Anchor is designed for a straightforward installation process using a drilled hole in the concrete substrate. Its controlled-torque expansion system is designed to provide a consistent fixing when installed in accordance with the applicable requirements.

For the supplied 10 × 90mm anchor, a 10mm diameter drill hole is required.

Basic Installation Process

While the exact installation procedure should follow the applicable ETA requirements and fixing instructions, the general process involves:

• Position the GRP profile where it is required.
  
• Mark the fixing position through the profile and onto the concrete.
  
• Drill a 10mm hole to the required depth for the anchor.
  
• Clean the drilled hole so that drilling debris does not interfere with installation.
  
• Insert the throughbolt assembly through the profile and into the prepared hole.
  
• Tighten the nut to the specified installation torque using suitable equipment.
  
• Check the completed fixing before proceeding with the installation.

The throughbolt assembly consists of a wedge bolt, clip, nut and washer, providing the components required for the anchor assembly.

Planning the Fixing Position

Correct positioning is important when installing anchors into concrete. The location of the fixing should take account of the profile, grating layout and the characteristics of the concrete substrate.

Particular attention may be required around concrete edges, corners and existing fixings, where spacing and edge-distance requirements can affect the installation.

Good to Know

The 10mm drill-hole specification applies to the supplied 10 × 90mm anchor. Always check the fixing specification and installation requirements for the exact anchor being used rather than applying this dimension to other sizes.

From the Mats4U Team

Don't treat drilling and fixing as the final step after designing the grating layout. Planning the anchor positions alongside the GRP profile and grating layout can help avoid awkward fixing locations and unnecessary adjustments during installation.

The Rawl ETA Throughbolt Anchor has been assessed for demanding structural fastening applications, including medium to heavy loads, cracked and uncracked concrete, seismic loading and fire resistance.

Its European Technical Assessment provides defined performance parameters for the anchor, giving project designers and installers technical information to consider when specifying the fixing.

Design Load Range

The stated assessment provides the following design load ranges:

• Non-cracked concrete: 5.6 to 32.8 kN
  
• Cracked concrete: 3.9 to 23.0 kN

These figures form part of the product's assessed performance and should not be treated as a universal load capacity for every installation.

The actual suitability of an anchor depends on factors including the concrete condition, embedment, fixing arrangement, spacing, edge distances and applied loads.

Seismic Applications

The anchor has been assessed for seismic applications under:

• Seismic C1: M8 to M20
  
• Seismic C2: M10, M12 and M20

The applicable anchor size and installation conditions should be checked against the relevant assessment requirements for the project.

Fire Resistance

The Rawl ETA Throughbolt Anchor is approved for fire resistance from R30 to R120 under the applicable assessment conditions.

This provides assessed performance information for projects where the fixing system forms part of an installation subject to specified fire-resistance requirements.

Good to Know

The load figures and fire-resistance classifications are assessment-specific. They should not be used to calculate the capacity of a complete GRP grating structure without considering the profiles, substrate, fixing arrangement and project loading.

From the Mats4U Team

For structural or heavily loaded installations, we recommend checking the relevant ETA documentation and project requirements before selecting the anchor size and fixing arrangement.

The Rawl ETA Throughbolt Anchor uses several steel components, each with a specified protective finish designed to provide durability in demanding installation environments.

Component Construction

The anchor assembly consists of:

• Shaft: Carbon steel with zinc plating ≥ 5 μm
  
• Washer: DIN 125 or DIN 9021, zinc plated ≥ 5 μm
  
• Nut: DIN 934, zinc plated ≥ 5 μm
  
• Clip: Carbon steel with sherardised coating ≥ 40 μm

The combination of carbon steel components and protective coatings provides corrosion protection suitable for the stated indoor and outdoor applications.

Suitable for Demanding Environments

The anchor is specified for use in:

• Dry areas
  
• Wet areas
  
• Oily and greasy areas
  
• Heavy-duty environments
  
• Indoor installations
  
• Outdoor installations
  
• Construction and industrial environments
  
• Chemical and shipping applications
  
• Water treatment facilities
  
• Offshore applications

The anchor is also specified as chemical resistant, although the suitability of the complete fixing should always be considered in relation to the particular chemicals and exposure conditions involved.

Good to Know

Zinc plating and sherardised coatings provide protection to the individual steel components, but no fixing should be assumed to be suitable for every chemical or environmental condition. The specific installation environment should always be considered.

From the Mats4U Team

If your GRP grating installation will be exposed to chemicals, saltwater, persistent moisture or other particularly aggressive conditions, tell us about the environment when choosing your fixing components so the complete fixing arrangement can be considered.
