Corrosion is a major problem for metal grating, stair treads and other products in many different industries such as chemical plants, food and beverage factories, water and wastewater facilities, power facilities. Sui Generis grating is particularly designed to provide safe, long-lasting, economical and worry-free solutions in environments where chemicals and other corrosive materials attack and destroy metal or wood. According to different environmental requirements, such resins as orthophthalic polyester, isophthalic polyester, vinylester or phenolic are chosen as matrix material.

2. High strength-to-weight ratio

Sui Generis grating is manufactured as a composite of continuous fiberglass strands and high quality resin, integrally constructed for strength. It is less than one-half the weight of steel grating allowing easy removal for access below floor level, and installation requires no heavy equipment and less manpower. Properly installed, Sui Generis gratings meet specified load requirements for steel and are more impact resistant than metal.

3. Fire retardant Safety

Sui Generis grating has a flame spread rating of less than 25 depending on different resin systems as tested to the ASTM E-84 Standards. Test Reports can be offered upon request. Special fire retardant requirements can also be met by including extra additives. Its NON-CONDUCTIVE properties make Sui Generis grating ideally suitable in electrically hazardous locations, acting as an insulator.

4. Ergonomic

For employees experiencing fatigue after standing on solid concrete or heavy non-adjustable galvanized steel platforms all day, Sui Generis grating is one of the best solutions to ease the strain on the backs, feet and legs of workers increasing workers’ comfort and productivity due to its natural slight resiliency that makes it easier to stand on for long periods. Moulded grating has a concave top surface for slip resistance after it is extracted from the mould. Should a grit surface be specified, the grit would be either bonded to the top of the completed grating as a secondary operation or embedded to the top of grating before heating, both providing superior slip resistancy. Diamond cover top or gritted cover top are also available upon request.

5. Low maintenance

Install it and forget about it. Sui Generis grating is easy to clean, its open mesh permits debris to fall through the grating panel, preventing a hazardous build-up on the walking surface. Sui Generis grating is free from re-painting year after year due to its molded-in color and ultraviolet stability. Also because of its inherent corrosion resistance, refurbishment is not necessary.

6. Comprehensive economical efficiency
The cost of Sui Generis FRP grating is about 1.4-1.8 times that of steel grating, but the installation cost is about 20-40% less and maintenance costs are effectively zero. Steel grating must be maintained and replaced so accumulated costs could be considerable. So, the cost of Sui Generis FRP grating is a little higher than that of steel grating, but the comprehensive economical efficiency, plus other advantages, is much higher than that of steel grating.
