Coal storage and material storage liner surfaces are smooth and glossy, uniformly loaded, capable of withstanding high impact forces, and possess stable mechanical properties. They are resistant to bending and deformation, featuring high mechanical strength, low tendency to deform, low water absorption rate, small density, high tensile strength, and low likelihood of cracking. Primarily used for fender boards at port wharfs, coal and material storage liner plates, and in industries such as construction machinery.
