style="text-indent:25px">樓房為什么有槽鋼層?因為槽鋼能夠具有一定的承重作用，所以可以用來分擔整個樓棟的重量，從而起到一個支撐和承重的作用。因此在建樓的時候，每一棟樓都必須要用到槽鋼。但是槽鋼的不足之處就是，只要有人頻繁地在上面走動就會發(fā)出一些噪聲。所以用槽鋼建造的那一層樓一般是用來擺放安裝設備的，是不住人的，所以這樣的樓層也就叫做槽鋼層。露天堆放的槽鋼應俯放，即口朝下，工字鋼應立放，鋼材的槽面不能朝上，以免積水生銹，堆碼的原則要求是在碼垛穩(wěn)固、確保安全的條件下，做到按品種、規(guī)格碼垛，不同品種的材料要分別碼垛，防止混淆和相互腐蝕禁止在垛位附近存放對鋼材有腐蝕作用的物品。槽鋼的交貨長度分定尺、倍尺二種，并在相應的標準中規(guī)定允差值。貨架槽鋼經銷商</p><p

style="text-indent:25px">槽鋼的腐蝕，化學腐蝕：附著在槽鋼表面的油污、灰塵及酸、堿、鹽等在一定條件轉化為腐蝕介質，與槽鋼中的某些成分發(fā)生化學反應，產生化學腐蝕而生銹；各種劃傷對鈍化膜的破壞，使槽鋼保護能力降低，易與化學介質發(fā)生反應,產生化學腐蝕而生銹。電化學腐蝕：與碳鋼件接觸造成的劃傷與腐蝕介質形成原電池而產生電化學腐蝕；割渣、飛濺等易生銹物質的附著與腐蝕介質形成原電池而產生電化學腐；焊接區(qū)域的物理缺陷(咬邊、氣孔、裂紋、未熔合、未焊透等)和化學缺陷(晶粒粗大、偏析等)與腐蝕介質形成原電池而產生電化學腐蝕。南京槽鋼企業(yè)</p></p><br
