The total thickness of color coated steel plate consists of three parts, steel plate thickness + coating thickness + coating thickness.Color coating products shall be described from five major aspects: substrate mechanical performance (yield strength, tensile strength, elongation rate), coating performance (coating type, coating adhesion, coating weight of coating), coating performance (film thickness, T bend, impact, pencil hardness, powder resistance, salt fog resistance, durability, etc.), surface quality (defect, gloss, color, coating fineness, etc.), other properties (plate type, size accuracy, tolerance, etc.).Different groups of people (architects, owners, processors, etc.) have a different understanding of this.From the production and use of color steel plate, the most important performance of color steel plate is its durability!
