High-durability carbon steel Zn Al Mg Coating square steel tubing 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.
High-durability carbon steel Zn Al Mg Coating square steel tubing have those advantages:
1.Highly corrosion-resistant
High-durability carbon steel Zn Al Mg Coating square steel tubing 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
High-durability carbon steel Zn Al Mg Coating square steel tubing 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,High-durability carbon steel Zn Al Mg Coating square steel tubing 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.
