Fiberglass Rebar


Corrosion has a huge environmental and economic impact on concrete structures. Reinforcing concrete with Glass Fiber Reinforced Polymer (GFRP) rebar is the ultimate solution to construct projects with strong mechanism against corrosive agents.

TUF-BAR manufactures the highest quality GFRP (Glass Fiber Reinforced Polymer) rebar using the highest quality corrosion resistant vinylester resin and fiberglass materials. Being a leader in the composite materials market, we have been manufacturing and selling supreme quality fiberglass rebar and accessories since 2000.

As a result of our extensive research for improved composite materials and production methods, TUF-BAR Fiberglass Rebar holds several patents related to the process of making the strongest GFRP Fiberglass Rebar.

We have developed the building codes for both Canada and The United States, establishing both the CSA codes which have been for the most part adopted as the ACI codes in addition to contributing to 6 LEED® credits in Canada and 7 in the USA.
