GFRP REBARS
Glass Fiber Reinforced Polymer (GFRP) rebars, also known as GFRP Bar, is a composite material made from high-strength glass fibers embedded in a polymer matrix, offering a lightweight, durable alternative to steel rebar.
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. While Fiberglass Rebar do not corrode, reducing maintenance and replacement costs, leading to long-term savings.
GFRP Rebars are 4x lighter, 2x stronger than steel rebar. It does not conduct heat, cold or electricity, substantially reduces workplace injuries, takes half the time to install with half the amount of people. It requires no maintenance or repairs and lasts longer than the concrete it is reinforcing.
With its superior properties, GFRP rebar is rapidly gaining popularity in various construction applications. Governments are increasingly specifying its use, and the world is beginning to recognize that Glass Fiber Reinforced Polymer is the ultimate solution for modern infrastructure needs.
WHY GFRP REBAR OVER TRADITIONAL STEEL REBAR ?
Structures using steel rebar in corrosive environments often start to fail after just 10 years. Corrosion costs private and public sectors billions of dollars each year in repairs and maintenance.
Glass Fiber Reinforced Polymer (GFRP) rebar can save these costs by being resistant to corrosion, eliminating failures in corrosive environments. It is also non-conductive and slightly lighter, making it easier to transport and install.
Whole of Life Savings
GFRP Rebar rebar has a 100 year design life cycle. Zero maintenance costs.
