Dragonbar™ Fiberglass Rebar (Fiberglass Reinforced Plastic Bar / GFRP Rebar ) are manufactured by pultrusion process and our new machining technology.Their mechanical properties and bond properties are very excellent compare with the steel rebar.And their have very good in corrosion environments and the design service life can reach 100 years.
The mian content material are reinforced fiberglass material and high properties resin.Therefore,the rebar show excellent properties to these following fields of applications:
Applications:
Barrier Wall；Roads；Bridges&Tunnels；Electrical Isolation；Marine Engineering；Water Fronts；Water Treatment lants；MRI Rooms, etc.
DESIGN CODE
FRP rebar do not follow the design code of steel rebar because the mechnical properties are different in some cases. FRP rebar has higher tensile strength but lower elasticity modulus compared to steel rebar. Therefore,we can not direct replacement of the design code of steel when using FRP rebar in projects.So some councils in some country have drawn up some codes for FRP rebar to engineers for reference.
