ST-BAR is a Glass Fiber Reinforced Polymer (GFRP) Rebar. It is the only GFRP Rebar that is an Integrally Ribbed Maximum Strength Rebar. MST-BAR is the only GFRP Rebar that bonds to concrete better than steel. Steel Rebar oxidizes in concrete which creates rust cancers. The oxidation process causes the rebar to expand which results in the cover concrete to spall, leading to failure.
MST-BAR is 4x lighter than steel rebar, 3x stronger than steel rebar, does not conduct heat, cold or electricity, substantially reduces workplace injuries, takes half the time to install with half the amount of people, requires no maintenance or repairs and lasts longer than the concrete it is reinforcing. Governments are specifying it and the world is starting to realize, MST-BAR is the solution.
MST Rebar Inc.’s specially engineered and designed Integral Rib mechanically locks MST-BAR into the concrete. Unlike every other rebar (steel or GFRP), the only way to pull it out of the concrete is to break the concrete itself.
