Composite gratings manufactured from fiberglass reinforced plastic (FRP/GRP) are engineered walkway and platform panels that replace steel gratings in corrosive, wet and electrically hazardous environments across the UAE and Saudi Arabia. They are extensively used on offshore oil and gas platforms, petrochemical plant access ways, desalination plant walkways, wastewater treatment facilities, food processing areas, power stations and marine terminals where conventional steel gratings suffer rapid corrosion and require constant replacement.

Available in molded (square-mesh) and pultruded (bearing-bar and cross-rod) configurations, FRP gratings offer complete corrosion immunity, a gritted anti-slip surface that remains effective when wet or oily, electrical non-conductivity, and a weight saving of 60-70 percent compared to equivalent steel gratings. Standard panel sizes typically measure 1220 x 3660 mm, with mesh openings of 38 x 38 mm being the most common, and load ratings designed for pedestrian or light vehicular traffic per NORSOK R-001 or OFFSHORE Technology Conference guidelines.

Procurement managers should specify mesh size, panel thickness (25 mm, 38 mm or 50 mm for standard molded grating), resin system (isophthalic polyester for moderate corrosion, vinyl ester for aggressive chemicals, phenolic for fire-rated areas), grit-top surface type (concave meniscus or gritted), colour, and fire classification (ASTM E84 Class 1, BS 476, or Lloyd's Register approval for offshore). Evaluate suppliers on stock availability, cut-to-size and drilling services, and supply of complementary items such as stair treads, handrail systems, clips and hold-down brackets.

Frequently Asked Questions β€” Composite Gratings

What is the difference between molded and pultruded FRP grating?
Molded grating is produced by pouring resin over woven glass rovings in a mold, creating a square-mesh bi-directional panel with equal strength in both directions. Pultruded grating consists of I-shaped bearing bars and cross-rods, offering higher strength in one direction and greater span capability. Molded grating is more common for general walkways, while pultruded grating suits heavy-load or long-span applications.
Is FRP grating approved for offshore platforms in the Gulf?
Yes. FRP grating with fire-retardant vinyl ester or phenolic resin is approved by classification societies including Lloyd's Register, DNV and ABS for offshore use. Products must demonstrate compliance with IMO fire test procedures and typically meet NORSOK R-001 requirements for offshore installations in the Arabian Gulf.
How much weight can FRP grating support?
Standard 38 mm thick molded FRP grating supports a concentrated load of approximately 4.5 kN with a deflection limit of span/100 on a 1-metre span. Pultruded grating can handle higher loads across greater spans. The manufacturer's load-span tables should be consulted for specific panel sizes and safety factors required by your project.
