Vinyl Ester (Type V) - Developed to withstand frequent and direct contact in the harshest of chemical environments. Type V is ideal for use in acidic and caustic environments such as chemical plants, waste water treatment, and plating applications. Isophthalic Polyester (Type I) – Industrial grade resin great for environments where fiberglass grating may occasionally be in contact with harsh chemicals due to splashes or spills. 

Food Grade Isophthalic Polyester (Type F) – Ideal for environments in the food and beverage industry where fiberglass grating may frequently be wet or exposed to harsh cleaning products. 

General Purpose Isophthalic Polyester (Type GPI) – A good general purpose resin great for environments such as food processing plants, dairies, and walkway applications, this resin is available at a reduced cost compared to the premium vinyl ester or isophthalic polyester resin. 

Extra Fire Retardant Isophthalic Polyester (Type XFR) – XFR offers an added level of fire safety for critical areas such as adjacent to sparking equipment, welding, or anywhere there is an increased fire potential. In accordance to ASTM E84 tests, flame spread is 10 or less. 

Phenolic (Type P) - Best choice for applications where fire resistance, low smoke, and low toxic fume emissions are critical. Typical applications include: offshore & onshore oil refineries, tunnels, ships, and train decks.
