DX52D+Z Galvanized Steel Pipe

Product Description

DX52D+Z galvanized steel pipe is made from DX52D grade cold-rolled steel and coated with a layer of zinc through the galvanizing process, indicated by the “+Z” designation. This steel grade offers good formability, making it suitable for deep-drawing applications without cracking or breaking. The zinc coating provides excellent corrosion resistance, ensuring durability even in harsh environments. DX52D+Z galvanized steel pipes are widely used in construction, automotive, and industrial sectors, where strength, corrosion protection, and reliability are essential. Their ability to withstand moisture, chemicals, and outdoor exposure makes them ideal for applications like structural components, handrails, and piping systems. This combination of strength and protection makes DX52D+Z pipes a cost-effective solution for long-lasting performance.

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.
