The resin system determines chemical resistance, fire performance and service life of FRP gratings. Here is a guide to selecting the right one.
Orthophthalic Polyester
Cost-effective for standard environments — ECO ST and ECO NFR grades.
Isophthalic Polyester
Enhanced chemical resistance for water treatment, marine and industrial applications.
Vinyl Ester
Maximum chemical resistance for aggressive environments — offshore, chemical plants.
Phenolic
Low smoke, high fire performance for tunnels and public spaces.
