Sheet material is a standard-sized flat rectangular building material board used in the construction industry as a component for walls, ceilings, or floors. It also refers to metal plates made by forging, rolling, or casting. Divided into thin plate, medium plate, thick plate, and extra thick plate, these materials are often produced by plate steel manufacturers. Hot rolled steel plate, including diamond plate steel and tread plate steel, is an indispensable material in many industrial fields, with advantages such as high strength, corrosion resistance, ease of processing, and low cost.
