Fiberglass substitute for steel fibers, this product is specifically designed as an alternative to steel fibers while also incorporating some characteristics of synthetic fibers. Compared to steel fibers, it boasts corrosion resistance, easy dispersion, ease of application, and non-damaging to mixing equipment. Made from synthetic resins, the product is processed through special technology and surface treatment, offering high tensile strength, good dispersion in concrete, and strong grip. It replaces steel fibers in cement concrete, overcoming the disadvantages of low tensile strength, small ultimate elongation, and brittleness of concrete. It has properties such as tensile, shear resistance, crack resistance, fatigue resistance, and high toughness, and has been applied in construction, road and bridge, and hydraulic engineering fields.
