Fiber reinforce plastic grating abbreviated as FRP grating is produced by resin and fibre glass through several special processes. The resin is used as the matrix, and the fibre glasses is used as a kind of reinforced material to increase the tenacity of the grating. Raw materials like resin and fibre glass is the key for the performace of gratings. High grade materials provide superior tenacity and smooth surface while low grade materials lead to poor quality which is easy for fracture and with rough surface. Our company always choose high grade resin and fibre glass as our raw materials to guarantee the quality.


1. Anti-corrosive: Superior corrosion resistance in the environment of acid, alkali, organic solvent, salt , and other gassy & liquid medium.

2. Light weight: the weight is only 1/4 of steel and only 2/3 of aluminum.

3. High Strenth: its intensity is 10 times higher than HPVC. The absolute intensity is far beyond that of aluminum and steel.

4. Easy for cutting and assembly due to its light weight.

5. Aging resistance: the theoretical service life is over 50 years.

6. Flame retardant: flame propagation rate is below 25 for ordinary flame retardant gratings and below 10 for high grade flame retardant gratings. The Oxygen index is over 28.

7. Safe for use: superior electrical insulating property, free of electromagnetism, anti-slip and anti-fatigue, etc.

8. There are various colors for customers’selection.


Widely used as platforms, stair treads, drain covers, bridge walkways, filter boards, infill panels etc. for petrochemical industry, power plant, marine engineering, galvanizing, shipping, water/waste water treatment, paper making, brewing and Pharmaceutical industries. They are ideal load-bearing components in corrosive environment.

Steel Grating Application

1) Galvanized steel grating from the flat width of 65mm-200mm thickness 5mm-20mm, such as welding formed galvanized steel grating for the post-heavy-duty galvanized steel grating suitable for large yard, docks, coal road bridges, etc., can carry large trucks pass.

2) Galvanized steel grating (Bearing Bar Spacing 40mm) spacing of 40mm steel hot dip galvanized steel grating is the most economical and lightweight varieties in the span of a smaller case, is the ideal choice.

3) Galvanized steel grating (Bearing Bar Spacing 60mm) flat steel bar spacing of 60mm to 50mm hot dip galvanized steel grating used in mining mineral mining industry to solve the problem of splash on the plate, often designated for mining processing plant

4) Galvanized steel grating (Bearing Bar Spacing 30mm) spacing of 30mm steel hot dip galvanized steel grating for the industry's most versatile breed in the common hot dip galvanized steel grating series, the impact on the surface the contact force of the strongest
