Performance comparison of fiberglass rebar to steel fittings

Comparative characteristics of fiberglass rebar with steel fittings

Fiberglass rebar for construction works.

A new reinforced element for construction works is high-strength non-metallic  rebar  made of composite materials.

Nonmetallic rebar  is produced in the form of a rod with spiral relief of any building length from glass fibers impregnated with a chemically resistant polymer.

According to the research results  of durability of building structures using the rebar is at least 80 years.

This durability is due to the high chemical resistance of the rebar  to all known aggressive medium - gas medium of high concentrations, chloride salts, deicing reagents, sea water, etc.

Comparative characteristics of fiberglass rebar with steel rebar.
