「鍍55%鋁鋅鋼捲」之鋁鋅合金結構是由55%鋁、43.4%鋅與1.6%矽在600ºC高溫下固化而組成, 其整個結構由鋁-鐵-矽-鋅,形成緻密的四元結晶體,此結晶體在鋼板上形成一層屏障, 因而有效的防止腐蝕因子穿透。
The aluminum-zinc alloy for 55% Al-Zn alloy-coated steel coils (GL) consists of 55% aluminum, 43.4% zinc and 1.6% silicon, solidified at 600ºC high temperature. The whole structure is a quaternary AI-Fe-Si-Zn compound which becomes a protection layer on the steel sheet to prevent penetration of corrosive factors effectively.
鍍鋅鋼捲因表面被覆鋅層阻隔大氣的侵蝕,以防止底材繼續腐蝕,及確保底材的使用壽命。
鍍鋅鋼捲還具有經濟性與多樣性,可符合不同環境,不同用途之要求,提供高附加價值之產品組合, 無論在精密儀器、資訊、電器、建築、烤漆等領域都已普遍採用鍍鋅鋼捲。
The zinc layer on the surface of the galvanized steel sheet isolates the steel sheet from atmosphere to prevent further corrosion of the base sheet and ensures a long service life of the base sheet, due to the excellent corrosion resistance of the galvanized steel sheets. Besides, our galvanized steel sheets (GL) are economic and functionally diverse, meeting the requirements of different environments and applications and provide high added value for various combination of products. Now, the galvanized steel sheets are in common use in many fields such as precision instruments, computers, electronic appliances, architectures, color coating, etc.
