Description
Product Overview This 25 mm galvanized square tube, with its compact and regular cross-section and superior craftsmanship, is suitable for various light-load, delicate structural applications.
The 25 mm square cross-section is lightweight and flexible, meeting the load-bearing requirements of small frames without creating material redundancy. The surface undergoes a fine galvanizing process, resulting in a smooth and uniform zinc layer with a refined visual texture and long-lasting rust protection.
Applications - Small shelving and display units - Decorative frame pieces - Garden supports and planters - Pet cage structures and small enclosures
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.
