Zn Al Mg Coated square hollow section for UK/AU is made of zinc-aluminum-magnesium alloy-coated steel coils through cold forming and high-frequency welding. It has excellent corrosion resistance and mechanical strength. Structural zinc-aluminum-magnesium square pipes are specially designed for harsh environments and integrate ternary alloy phases (zinc, aluminum, magnesium) to form a self-healing protective layer, making them ideal for long-term structural applications.
Zn Al Mg Coated square hollow section for UK/AU have those advantages:
1.Highly corrosion-resistant
Zn Al Mg Coated square hollow section for UK/AU Mg addition stabilizes pH at scratch sites, forming protective hydroxides (e.g., Simonkolleite) to prevent rust spread.
Outperforms traditional galvanized coatings by 4-20× in salt spray tests
2. High structural strength and stability
Zn Al Mg Coated square hollow section for UK/AU is made of Carbon Steel Zinc-Al-Mg coated Coils, which has sufficient structural strength and stability, and can well resist the impact of earthquakes and wind and snow on the bearing capacity.
3. Self-Healing Coating
Mg-rich phases oxidize to seal micro-cracks, maintaining integrity under mechanical stress,Zinc-Al-Mg coated square steel tube have self-healing coating.
4.Wide Temperature Tolerance
Stable performance from -40°C to 120°C, ideal for outdoor and industrial settings.

FAQ 1:Why choose Zn-Al-Mg over pure zinc coatings?
A: Mg forms a dense oxide layer to block corrosive ions, extending service life to 25+ years.
FAQ 2:Can tubes be welded without damaging the coating?
A: Yes - pre-coated edges allow welding with minimal spatter; post-weld Mg oxidation self-repairs affected areas.
FAQ 3:What is the MOQ?
A: Standard MOQ: 5 tons (custom sizes available).
FAQ 4: How does the factory ensure product quality and compliance?
A: The company employs advanced testing equipment, including spectrometers (for material composition) and Q-FOG salt spray testers (for corrosion resistance). Products comply with international standards like ISO 9001 and are certified for structural reliability in solar applications.
FAQ 5: What are the minimum order requirements and lead times?
A: The minimum order quantity is 2 tons, with a FOB price range of 2,450-2,950/ton. The factory's monthly production capacity is 5,000 tons, ensuring quick turnaround times. Orders are shipped via the Port of Qingdao, with payment terms like T/T (Telegraphic Transfer) accepted.
