Description
Product Overview This 60×80 galvanized rectangular tube, with its optimized cross-sectional proportions and superior manufacturing process, is a powerful choice for medium-load structural applications.
The 60×80 flat rectangular design combines bending stiffness with load-bearing stability, increasing load-bearing efficiency by 30% compared to round tubes of the same size. The surface is treated with hot-dip galvanizing, resulting in a uniform, dense, and flawless zinc layer.
Key Features - 30% higher load-bearing efficiency than round tubes - Precision cutting with clean, burr-free cuts - Uniform wall thickness meeting industry standards - Lightweight for easy transportation and handling
Applications - Steel structure factory auxiliary frames - Large agricultural greenhouse main supports - Commercial display rack keels - Logistics warehouse heavy-duty shelving
Galvanizing Process
Our galvanized rectangular 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.
