DX52D+Z Galvanized Steel Pipe

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.

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.

DX52D+Z Galvanized Steel Pipe adheres to EN 10346 and ASTM A653 specifications, with outer diameters ranging from 12mm to 150mm and wall thicknesses of 0.6mm–5.0mm. Standard lengths are customizable from 2m to 12m (fixed or random cuts), suitable for construction, automotive, and HVAC applications. The zinc coating (60–180g/m²) is rigorously tested using XRF (X-ray fluorescence) and magnetic thickness gauges to ensure uniformity and compliance with Z100-Z275 classifications. Critical tolerances, including ovality (±0.5%), straightness (±0.1% per meter), and surface finish (smooth, spangle-free), are verified via 3D laser scanning. Mill test certificates (EN 10204 3.1/3.2) validate mechanical properties such as yield strength (140–220MPa), tensile strength (270–380MPa), and elongation (≥28%), ensuring exceptional formability for bending and welding applications.

DX52D+Z Galvanized Steel Pipe is securely packaged to ensure durability and corrosion resistance during global logistics. Each pipe is tightly bound with galvanized steel straps and sealed with reinforced plastic or steel end caps to prevent moisture ingress and edge deformation. For extended storage or high-humidity environments, pipes are wrapped in VCI (Volatile Corrosion Inhibitor) film or coated with anti-rust oil to protect the zinc layer (Z100–Z275). Custom packaging options, such as hexagonal bundling, wooden crates, or palletized configurations, are available for bulk orders. All packages are labeled with grade (DX52D+Z), dimensions, zinc coating weight, and QR codes for real-time tracking, complying with ISO 9001 and EN 10346 standards to meet international shipping requirements.
