style="text-indent:25px">槽鋼的防腐作用：如果氧化鋅與大氣中其它成分生成不溶性鋅鹽后，則防腐蝕作用更理想。槽鋼耐蝕性主要決定于鍍鋅層的厚度，將較厚致密的純鋅層覆蓋在槽鋼表面上，可以避免槽鋼基體與任何腐蝕溶液的接觸，耐腐蝕能力非常強(qiáng)，保護(hù)槽鋼免受腐蝕，又能夠長(zhǎng)期與鋼結(jié)構(gòu)牢固粘接在一起，防止表面受到損傷。鋅在干燥空氣中不易發(fā)生變化，而在潮濕的空氣中，表面能生成一種很致密的鍍鋅薄膜，經(jīng)過鍍鋅處理之后的槽鋼的表面會(huì)非常美觀，而且還有著較強(qiáng)的抗腐蝕性。進(jìn)口槽鋼標(biāo)明實(shí)際規(guī)格尺寸及相關(guān)標(biāo)準(zhǔn)。大型槽鋼哪個(gè)好</p><p
