DX51D+Z Galvanized Steel Coil
Product Description
DX51D+Z galvanized steel coil is a widely used steel product, characterized by its excellent formability, corrosion resistance, and moderate strength. The “DX51D” grade refers to a cold-rolled steel with good mechanical properties suitable for general-purpose applications, while the “+Z” indicates a layer of zinc coating, applied through the hot-dip galvanizing process, which enhances the steel’s ability to resist rust and wear. Typically, the zinc coating thickness ranges from 60 g/m² to 275 g/m², providing long-lasting protection against environmental elements. This galvanized steel coil is commonly used in industries such as construction, automotive, home appliances, and manufacturing, offering durability, ease of processing, and improved performance in harsh environments.

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.
