FRP Grating

Product catalog summary

Resin Types:
Two types of resin are used in the fibreglass grating products: Type 'I' (green) uses isophthalic polyester resin, offering excellent corrosion resistance across a broad range of chemicals, and Type 'V' (yellow) uses vinylester resin, providing superior corrosion resistance to acidic environments and moderate resistance to caustic and solvent applications. Both types have a Class 1 flame spread rating of 25 or less.

Product Coding:
The product coding includes specifications for both isophthalic and vinylester fibreglass grating, with various dimensions and thicknesses available. Standard panel size is 3660 x 1220 mm, with weights of 51 kg for 25 mm depth and 82 kg for 38 mm depth.

Construction and Design:
The FRP grating is a one-piece, fully moulded fibre reinforced plastic, designed for even load distribution with a 38 x 38 square mesh pattern and 70% open area. It features 6 mm thick load-bearing bars in both directions.

Applications:
Primarily used for flooring, access walkways, platforms, screening, battery racks, bridges, sump/trench covers, machine guards, and stair treads. It serves as an alternative to aluminium or stainless steel grating, especially in caustic or corrosive environments.

Benefits:

Excellent strength-to-weight ratio with even load distribution.
Anti-slip properties due to grit top surface.
High corrosion resistance.
Fire resistant with a Class 1 flame spread rating.
Non-sparking, non-magnetic, and non-conductive, making it suitable for hazardous areas.
Lightweight and easy to install without mechanical hoists.
Minimal wastage due to square pattern design.
Easy to cut and customize on-site with standard tools.
