敷鋁鋅板也叫覆鋁鋅板、鍍鋁鋅鋼板鋁鋅合金結(jié)構(gòu)由55%鋁、43.4%鋅與1.6%硅600℃高溫下固化而組成其整結(jié)構(gòu)由鋁－鐵－硅－鋅形成致密四元

結(jié)晶體從而形成層強(qiáng)有效防止腐蝕因子透穿屏障。鍍55%鋁鋅鋼卷耐腐蝕性來自鋁障礙層保護(hù)功能和鋅犧牲性保護(hù)功能當(dāng)鋅切邊、刮痕及鍍層擦傷

部分作犧牲保護(hù)時鋁便形成能溶解氧化物層發(fā)揮屏障保護(hù)功能鍍鋁鋅合金鋼卷已各種同大氣環(huán)境進(jìn)行了20多年室外曝露試驗(yàn)證實(shí)鍍55%鋁鋅鋼板切邊

保護(hù)功能比鍍5%鋁鋅鋼板佳。

Aluminum zinc plate is also called aluminum zinc plate, aluminum zinc steel plate aluminum zinc alloy structure of 55% aluminum, 43.4% zinc and 1.6% silicon

600℃ at high temperature and the whole structure is formed by aluminum-iron-silicon-zinc to form a dense quadruple crystal, thus forming a layer to effectively prevent corrosion factor penetration barrier.Plating 55% aluminum zinc steel roll corrosion resistance from aluminum barrier layer protective function and zinc sacrificial protective function when zinc cutting edge, scratches and coating abrasion for the sacrifice of aluminum can form dissolved oxide layer play barrier protection function aluminum zinc alloy steel roll has been with atmospheric environment for more than 20 years of outdoor exposure test confirmed that

plating 55% aluminum zinc steel sheet edge cutting protection function is better than 5% aluminum zinc steel plate.
