Description
Product Overview This 50 mm galvanized square tube, with its square cross-section and superior craftsmanship, is a practical choice for various structural projects.
The 50 mm square cross-section inherently possesses a regularity, achieving a uniform visual effect and stable load-bearing capacity whether assembled into shelving frames, guardrail posts, or used as decorative framing. The evenly distributed galvanized layer provides long-lasting rust protection in humid outdoor and mildly corrosive industrial environments.
Key Features - Cold-cut saw process for smooth, burr-free cuts - Uniform wall thickness for structural strength - Lightweight for easy handling - Direct installation without secondary processing
Applications - Warehouse shelving systems - Agricultural greenhouse frames - Residential fencing and guardrails - Commercial display frames
Galvanizing Process
Our galvanized square tubes undergo a meticulous hot-dip galvanizing process. The production chain includes: 1) Alkaline degreasing at 80°C to remove fabrication oils; 2) Hydrochloric acid pickling to remove mill scale and rust; 3) Fluxing in zinc ammonium chloride solution; 4) Immersion in molten zinc bath at 445–455°C; 5) Controlled cooling and inspection.
