Galvalume plating is to plate aluminum-zinc alloy coating on the surface of steel to form a protective film to prevent oxidation and corrosion on the surface of steel.

Galvanized square pipes are treated with advanced hot-dip galvanizing technology, which can form a uniform zinc layer on the surface of the pipe body, making the pipe body anti-corrosion. Even under harsh environmental conditions, such as high temperature, humidity, corrosion, etc., it can maintain a long service life.

Hot-dip galvanized steel pipe has the characteristics of surface gloss, uniform zinc layer, no leakage, no dripping, strong adhesion, and strong corrosion resistance. It has greatly increased in suburban environments. The standard hot-dip galvanized rust-proof thickness can be maintained There is no need for repairs for more than 50 years; in urban or offshore areas, the standard hot-dip galvanized anti-rust layer can last for 20 years without repairs.

镀锌钢卷表面具有特征性的光滑、平整、华丽的星花，基色为银白色，特殊的镀层结构使其具有优良的耐腐蚀性能。

Zinc-aluminum-magnesium (Zn-Al-Mg) alloy is a new type of lightweight and high-strength material. It has excellent corrosion resistance. Zinc-aluminum-magnesium alloy is one of the strongest materials currently on the market.

Alloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. Mainly different from the production standards of alloy pipes and its industry, annealing and tempering of alloy pipes changes its mechanical properties. achieve the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes in terms of variable utilization. The chemical composition of alloy pipes contains more Cr, and it has high temperature resistance, low temperature resistance and corrosion resistance.
