Products Description
Steel GI Pipe Related Products Hot-dip galvanizing it is an effective metal anti-corrosion method, mainly used in metal structure facilities in various industries. The rust-removed steel parts are immersed in a molten zinc solution at about 500掳C, so that a zinc layer is attached to the surface of the steel parts, thereby achieving the purpose of anti-corrosion. And the Steel GI Pipe process: finished product pickling-water washing-adding auxiliary plating solution-drying-rack plating-cooling-medication-cleaning-polishing-hot-dip galvanizing completed.

Technical parameter
Galvanized pipes are widely used in industries such as construction, chemical, and petrochemical, mainly for transporting gas, paint, water, and some highly corrosive media.
In addition, galvanized pipes are widely used in municipal engineering, bridges and other construction projects, with good corrosion protection and structural stability.
