BYQ type extruded fiberglass bridge is a type of fiberglass profile that is made by impregnating continuous glass fiber untwisted coarse sand, glass fiber continuous felt, surface felt, and other reinforcing materials with thermosetting resin. Under the action of traction, the resin is pulled out from a heated metal mold and cured at high temperature and high pressure, resulting in continuous, smooth surface, stable size, and high strength. And it is formed under high temperature and high pressure, so the material composition of the spliced fiberglass bridge is more reasonable, with stronger aging resistance, uniform material, high strength, stable size, and beautiful appearance.
