DX56D+Z Galvanized Steel Coil

Product Description

DX56D+Z is a hot-dip galvanized steel coil designed for applications requiring high formability, strength, and excellent corrosion resistance. The “DX56D” grade indicates a steel with higher tensile strength compared to lower-grade galvanized steels, making it suitable for demanding forming processes like deep drawing, bending, and stamping. The “+Z” designation refers to the zinc coating applied to the steel, offering effective corrosion protection, especially in outdoor or corrosive environments. DX56D+Z coils are widely used in industries such as automotive, construction, and appliances, where long-lasting durability and resistance to weathering are essential. With its smooth surface, good weldability, and robust protection against corrosion, DX56D+Z steel is an ideal choice for applications exposed to moisture, humidity, and other environmental elements.

Product Inspection

The appearance of the coating is bright, meticulous, without sagging or wrinkles. Thickness inspection can use coating thickness gauge, the method is relatively simple. The thickness of the coating can also be obtained by converting the amount of zinc adhesion. For the bonding strength, a bending press can be used to bend the sample at 90-180°, and there should be no cracks or peeling of the coating. A heavy hammer can also be used to test, and the salt spray test and copper sulfate corrosion test can be done in batches.
