General Introduction

Glass fiber reinforced plastic (FRP) grating and glass fiber reinforced plastic plate, is a kind of glass fiber reinforced material, unsaturated polyester resin as matrix, through special processing and become a kind of plate material, with lots of blank space FRP gratings can be used as a structural material, used for the floor of the corrosion environment, trench cover, platform, ship deck, stair, catwalks, etc. With corrosion resistance and flame retardant, non - magnetic insulation, bright colors, a variety of styles and forms of alternative features.


Material Introduction

Resin
Resin Type Resin Base Description Corrosion Resistance Flame Spread Rating ASTM E 84 Colors Available
VEFR225 Vinyl ester Superior corrosion resistance and retardant  Excellent Class 1.25 or less Dark gray, orange
IFR-25 Vinyl ester Industrial grade corrosion resistance and fire retardant Very good Class 1.10 or less Dark, gray
IFR-10 Isophthalic polyester Industrial grade corrosion resistance and extra fire retardant Very good Class 1.25 or less Custom
OFR-30 Isophthalic polyester Food grade corrosion resistance and fire retardant Very good Class 1.10 or less Light gray, light green 
OFR-25 Ortho Moderate corrosion resistance and fire retardant Moderate Class 1.25 or less Green, yellow, light gray, dark gray
MP-5 Phenolic resin Low smoke and superior fire resistance Very good Class 1.25 or less Reddish-brown, phenolic painting of the grating can be formed to obtain a gray or red finish
O-CR Ortho Moderate corrosion resistance Moderate No Green, yellow, light gray, dark gray

                               

Fiberglass Type
Code Roving Type Application Situation
E
E-glass roving High strength and high corrosion resistance requirement.
C C-glass roving More economical than E-glass roving, has less strength, but better in acid resistance.


Filling
Code Roving Type Application Situation
ATH Aluminum hydroxide Flame retardant, smoke suppression, corrosion resistance situation
CAO Calcium carbonate More economical than ATH, suitable for no flame retardant requirement
PR No filling  High corrosion resistance requirement situation
