Features of Fiberglass rebar

Feb 13, 2023

Fiberglass rebar (fiber reinforced bar), a new type of composite material formed by pultrusion with high-strength glass fiber, basalt fiber, etc. as reinforcing materials, synthetic resin and auxiliary agents as matrix materials. Products are widely used in subway tunnels, expressways, bridges, airports, docks, stations, water conservancy projects, underground projects and other fields.

Features of Fiberglass rebar
 

Light weight:

Only 1/4 of the same volume of steel bars; the density is between 1.5-1.9 (g/cm).
 

Strong corrosion resistance:

Corrosion resistance to acids and alkalis and other chemicals can resist the erosion of chloride ions and low pH value solutions, especially the corrosion resistance of carbon compounds and chlorine compounds is stronger.
 

Easy cutting and convenient construction:

The cutter head can be cut directly, and various standard and non-standard parts with different cross-sections and lengths can be produced according to user requirements. Non-metal tension straps can be used for on-site binding, and the operation is simple.
 

Strong concrete binding force:

Compared with steel, the thermal expansion coefficient is closer to cement, so the binding force with concrete is stronger.
 

Strong designability:

Stable elastic modulus. Dimensional stability under thermal stress, bending and other shapes can be arbitrarily thermoformed; good safety performance, no heat conduction, no conduction, flame retardant and antistatic, through formula change and metal Collisions do not produce sparks.
 

Strong performance of magnetic wave penetration:

This material is a non-magnetic material, and it does not need to be demagnetized in non-magnetic or electromagnetic concrete components.
