DX56D+Z Galvanized Steel Pipe
Product Description
DX56D+Z galvanized steel pipe is made from DX56D grade cold-rolled steel, which is coated with a layer of zinc through the galvanizing process, denoted by the “+Z” designation. This steel grade is known for its excellent formability, making it suitable for deep drawing and bending without compromising structural integrity. The zinc coating provides robust corrosion resistance, ensuring the steel pipe can withstand exposure to moisture, chemicals, and harsh weather conditions, prolonging its lifespan. DX56D+Z galvanized steel pipes are commonly used in industries such as construction, automotive, and manufacturing for applications requiring high strength and durability. These pipes offer a cost-effective, long-lasting solution for structural support, piping, and other environments where protection against rust and corrosion is crucial.

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.
