GRP Channel for Ladder Rail

The FRP channel products can resist corrosion from various gas or liquid such as acid,alkali,organic solvent and compound.They can be used as ladder material,and used in the electricity industries.

 

Pultrusion profile is a kind of compound materials which is formed by taking fiberglass as the reinforced material, and taking thermosetting resin as base, the fiberglass continuous roving enable the product to have the extremely high longitudinal strength, the fiberglass mat (continuous strand mat, knitted mat and so on) makes the product have the good transverse strength. The thermosetting resin base is usually the unsaturated polyester resin, the vinly resin, the resin base enable the product to have the good anti-corrosion property, the different resin enables the product to be suitable for various corrosion environment, to add the ultraviolet inhibitor and fire retardant may enable the product to have the outstanding anti-aging property and the different rank anti-flammable property.
