Glass Fiber Rebar(GFRP Bar)

What is fiberglass rebar?

Fiberglass rebar is a kind of new advanced material, widely applied in underground tunnel, highways, bridge, airport, dock, station, water projects, etc. Because of its anti-corrosion, it can be applied in sewage disposal facilities, chemical factory, electrolysis bath, manhole cover, marine facilities. It’s also used in structural strengthening, structural reinforcement, concrete repairs and seismic retrofitting. Fiberglass can be the solution to many existing projects problems, not like corrosive steel rebar, it brings the new opportunity for construction development.

Advantages of Fiberglass Rebar

1. high strength, 20% stronger than steel rebar with the same diameter, meanwhile with good anti-fatigue property.
2. light weight, only 1/4 weight of steel rebar with the same diameter, its density is between 1.5 and 1.9g/cm³.
3. anti-corrosive, no matter alkali or acid, the fiberglass rebar can retain its mechanical properties in harsh environment.
4. good integration, fiberglass rebar has similar coefficient of thermal expansion with concrete, so it has better bonding strength with concrete structures.
5. low thermal and electricity conductivity.
6. Non-magnetic.
7. Easy handling. The fiberglass rebar can be customized for different diameter and length as per project requirement. It can be tied with non-metal strap.
8. Fiberglass is cheaper than steel rebar in the long run, considering the maintenance cost.
