Steel structure has worldwide applications in construction material ranges, especially in range of large span workshops, logistics, offices, etc, which depend on the comprehensive advantages of lightweight, easy assembly, shortest construct, shake resistance, instant return of investment and recycling. Ahead with the applications of steel products, another thing worries the architect is the anticorrosive, which can influence the working life of the steel structures in high degree. As the development of the techniques of the embalmment to steel, there come out two kinds of treatment: Cold Galvanized and Hot-dipped Galvanized.

The cold galvanized technique is called electrolytic zinc plating, less Zinc quantity, poor in electrolytic zinc plating compared to hot-dipped galvanized tube and easily damaged in assembly and transportation. The hot-dipped galvanized tactics is to make reaction of molten metal and steel so as to produce the alloy coating, which combines the basic body and the alloy coating. Hot-dipped galvanized techniques is that acid washes the steel tubes at the beginning to get rid of ferric oxide of the surface, after that, washed in mixed liquor of ammonium chloride and zinc chloride ,alternatively in liquor of ammonium chloride, hot-dipped in ammonium chloride finally.

Hot-dipped galvanized techniques has advantages of well mixed cladding material, strong adhesive force and long working life, etc. It is difficult to damage in transportation and assembly all thanks to its specific alloy coat. Outstanding corrosive resistance function guarantees working life for 30 years at least and 40 years if used for interior or closed spaces. EAST Textile Architecture Company guarantee all products quality for our customers and we promise all steel components are treated by hot-dipped galvanized techniques.
