鍍鋁鋅鋼板

鍍鋁鋅鋼板

Galvanized steel sheet



       鍍鋁鋅鋼板表面呈特有的光滑、平坦和華麗的星花,基色為銀白色。特殊的鍍層結構使其具有優良的耐腐蝕性。鍍鋁鋅板正常使用壽命可達25a,耐熱性很好,可用于315℃的高溫環境;鍍層與漆膜的附著力好,具有良好的加工性能,可以進行沖壓、剪切、焊接等;表面導電性很好。
鍍層成份按重量比率分別由55%的鋁和43.4%的鋅,1.6%的硅組成。鍍鋁鋅鋼板的生產工藝與鍍鋅鋼板和鍍鋁板的工藝相似,是連續熔融鍍層工藝。55%鋁鋅合金鍍層的鍍鋁鋅鋼板當雙面暴露于同樣的環境時與相同厚度的鍍鋅鋼板相比具有更優越的耐腐蝕性。55%鋁鋅合金鍍層的鍍鋁鋅鋼板不僅具有良好的耐腐蝕性外,彩涂產品具有優秀的附著力和柔性。


       The surface of the aluminized and galvanized steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of aluminized galvanized sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.
The composition of the coating is composed of 55% aluminium, 43.4% zinc and 1.6% silicon in weight ratio. The production process of aluminized galvanized steel sheet is similar to that of galvanized steel sheet and aluminized steel sheet. It is a continuous melting coating process. Compared with galvanized steel sheet with the same thickness, galvanized steel sheet with 55% Al-Zn alloy coating has better corrosion resistance when exposed to the same environment on both sides. Aluminum-zinc plated steel with 55% Al-Zn alloy coating not only has good corrosion resistance, but also has excellent adhesion and flexibility.
