Molded Fiberglass Gratings are used for their high strength, corrosion resistance, light weight, long life and safety. All FRP grating is made to meet the highest international standards.
Molded fiberglass grating also has many advantages over steel grating for performance and cost effectiveness. With a much higher strength-to-weight ratio, molded fiberglass grating is easy to handle, making for quick installation.
Molded Grating Resin Systems
HESLY FRP Grating Trench and Drain Grates are available in two standard resin systems. Each providing different levels of corrosion protection. Both resin systems meet Class 1 Flame Spread Rating per ASTM E-84 test standards.
Polyester: A premium-grade isophthalic polyester resin system that provides excellent corrosion protection. Standard colors: Dark Gray, Light Gray, Yellow, and Green. Equivalent to Fibergrate Corvex and Strongwell Duragrate PP.
Vinyl ester: A chemically resistant system that provides the highest level of corrosion protection. Standard colors: Yellow, Dark Gray, and Orange. Equivalent to Fibergrate Vi-Corr and Strongwell Duragrate VE.
