Product introduction
With glass fiber or basalt fiber as its reinforcing material , and pultrusion resin and auxiliary agent as its cementing material , frp rebar is a new type of composite material , which is shaped by pultrusion and traction .Fiberglass rebar (grp) and basalt rebar are the two patent products of our company.
Product characteristics
1.Corrosion-resistance:will not rust, and are impervious to the action of salt ions, chemicals, and the alkalinity inherent in concrete.
2.High tensile strenghth:higher than normal steel rebar by 20%.
3.High bond strength:thermal expansion coefficient is close to cement, better than steel bar in concrete.
4.Lightweight:weigh approximately one-quarter the weight of an equivalent size steel bar.
5.Electromagnetic neutrality:contain no metal, and will not interfere with the operation of sensitive electronic devices such as medical MRI units or lectronic testing devices.
