Molded grating panels are available in three standard resin systems that meet Class 1 Flame Spread Rating per ASTM E-84 test standards, each providing levels of corrosion protections. Molded grating panels are strong yet lightweight, remain stable in many environments, are corrosion resistant and have a slip resistant top surface. 
Molded grating panels come standard in the following resins:  
-  PFR - A general-purpose orthophthalic polyester resin system that offers good corrosion resistance at an economical price. 
 (Comes standard in Green, Yellow, Dark Gray and Light Gray)
-  IFR - A premium-grade isophthalic polyester resin system that provides excellent corrosion protection.
