Application FAQ

Expert answers for common construction rebar & profiles engineering queries.

Why use FRP rebar instead of steel?

FRP rebar is 1/4 the weight of steel, non-corrosive, and non-conductive, making it ideal for sea walls and MRI rooms.

Is it compatible with standard pultrusion equipment?

Yes, our resins are drop-in solutions for most standard pull-line configurations.
