Coal storage and material storage liner surfaces are smooth and shiny, uniformly bearing loads, capable of withstanding high impact forces, with stable mechanical properties, not prone to bending or deformation. They offer high mechanical strength, low tendency to deform, low water absorption rate, small density, high tensile strength, and are not easily cracked. Mainly used for fender boards at ports and docks, coal and material storage liner plates, and in industries such as construction machinery.
