As a substitute for the steel rebar, the practical GFRP is provided at a competitive and lower price, which is made with composite materials and produced by GF Material Technology Co., Ltd. It is safe because its strength is higher than that of the steel rebar. Moreover, as a rust- and corrosion-resistant material and an insulating product, it lengthens life of building, thus it is eco-friendly product. And, GF Material Technology Co., Ltd. has developed the mass production system to lower the cost of production by standardizing the product thickness and by allowing mass production, so our company has expanded all over the world.
