Welcome to Cangyuantu Co., Ltd.
Basalt fiber rebar is an excellent concrete reinforcement product. It is 4 times lighter than rebar and has 3 times higher tensile strength. Basalt rebar is made from basalt fiber by pultrusion technology. The surface is shaped and sanded. This finish can create better adhesion in concrete.
The basalt fiber reinforcement produced by Cuang yuan tu with new technology and new process can completely replace ordinary steel reinforcement and rebar; Compared with ordinary reinforcement, it has strong advantages: (see Annex for technical parameters)
1.The purchase cost is lower than that of ordinary reinforcement,
2. The strength is 200% of the ordinary reinforcement with the same specification and diameter; The tensile strength reaches 1100mpap; The reinforcement is only 450MPa,
3. Basalt fiber rebar, especially with high acid, alkali and corrosion resistance, is a kind of electrical insulator that will never rust.
4. Basalt fiber reinforced bar, which is non-magnetic. It has high tolerance to the moisture concentration in cement mortar and the penetration and diffusion of carbon dioxide, and can prevent the corrosion of concrete structure in harsh environment, so as to improve the durability of buildings and bridges.
5. The specific gravity of basalt fiber reinforcement is 2.1g/cm3; The specific gravity of steel and reinforcement is 7.85/cm3; The diameter weight of the same specification is 270% lighter than that of steel reinforcement, and the strength is 200% of that of steel reinforcement.
6. The physical properties of basalt fiber reinforcement are higher than that of reinforcement, and the cost is lower than that of reinforcement. Replacing reinforcement has epoch-making significance.
7. Basalt fiber rebar price: $0.6--$1.6/m FOB from Shanghai
Compared to steel, basalt filament is stronger at the same diameter, weighs a fraction of the weight at the same strength, and is immune to acids, alkalis, and corrosion. The superior strength, light weight, and final product cost of basalt rebar make it suitable for new applications.
