在金屬外(wai)表(biao)掩蓋保護層(ceng)(ceng)，阻隔(ge)周圍腐蝕(shi)介質，然后(hou)避(bi)免抵達防腐蝕(shi)作用。例如：在鋼板網外(wai)表(biao)涂上(shang)機油、凡士林、油漆或掩蓋琺瑯、pvc等(deng)的非金屬材料；用電(dian)鍍、熱鍍、噴鍍等(deng)方法(fa)，在鋼板外(wai)表(biao)鍍上(shang)一層(ceng)(ceng)鋅、鉻、鎳等(deng)；用化學方法(fa)使鋼鐵(tie)外(wai)表(biao)生(sheng)成一層(ceng)(ceng)細(xi)密(mi)安穩的氧化膜。如在機器(qi)零(ling)件(jian)、槍炮等(deng)鋼板制件(jian)外(wai)表(biao)構(gou)成一層(ceng)(ceng)細(xi)密(mi)的黑色四氧化三鐵(tie)薄膜等(deng)。

    常常擦洗(xi)金(jin)屬器(qi)(qi)件(jian)或許在(zai)(zai)精(jing)密(mi)儀器(qi)(qi)中(zhong)放置干燥劑和在(zai)(zai)腐蝕(shi)介質中(zhong)參(can)與少數能減慢腐蝕(shi)速度的(de)緩(huan)蝕(shi)劑等(deng)(deng)(deng)。按材(cai)料分(fen)類：低(di)碳鋼(gang)(gang)薄板(ban)，鋁板(ban)，不(bu)銹鋼(gang)(gang)板(ban)，鋁鎂(mei)合(he)金(jin)板(ban)、鋼(gang)(gang)板(ban)等(deng)(deng)(deng)各(ge)種(zhong)(zhong)板(ban)材(cai)。按用處分(fen)類：用于(yu)公(gong)路、鐵路、民用建筑、水利(li)等(deng)(deng)(deng)制(zhi)作，各(ge)種(zhong)(zhong)機械，電器(qi)(qi)、窗戶(hu)的(de)防護(hu)及水產(chan)飼養等(deng)(deng)(deng)。可(ke)根據客戶(hu)需(xu)求加工定做(zuo)各(ge)種(zhong)(zhong)特(te)別(bie)規范產(chan)品。

    重型(xing)鋼(gang)板(ban)(ban)網(wang)(wang)是金屬(shu)絲網(wang)(wang)職業中(zhong)的(de)一個種(zhong)(zhong)類。又名防眩網(wang)(wang)、金屬(shu)擴張網(wang)(wang)、拉伸(shen)(shen)網(wang)(wang)、鐵(tie)板(ban)(ban)網(wang)(wang)、沖孔網(wang)(wang)等(deng)。是金屬(shu)板(ban)(ban)材(cai)通過特(te)種(zhong)(zhong)機械的(de)沖壓、拉伸(shen)(shen)后(hou)，構成具有網(wang)(wang)孔的(de)片狀物體(ti)。重型(xing)鋼(gang)板(ban)(ban)網(wang)(wang)材(cai)料：低碳鋼(gang)板(ban)(ban)、不銹鋼(gang)板(ban)(ban)、鋁鎂合金板(ban)(ban)、鋁板(ban)(ban)、銅板(ban)(ban)、鈦板(ban)(ban)、鎳板(ban)(ban)。

    重(zhong)型鋼板(ban)(ban)網(wang)是一(yi)(yi)種載重(zhong)量較大的(de)(de)鋼板(ban)(ban)網(wang)產品，它能(neng)(neng)夠選用(yong)(yong)：一(yi)(yi)般(ban)鋼板(ban)(ban)、不銹鋼板(ban)(ban)、鐵板(ban)(ban)、銅板(ban)(ban)、鋁板(ban)(ban)、鈦板(ban)(ban)、鎳板(ban)(ban)等(deng)為材(cai)料，經(jing)沖(chong)床高壓沖(chong)壓、拉伸而成(cheng)。重(zhong)型鋼板(ban)(ban)網(wang)的(de)(de)用(yong)(yong)處：能(neng)(neng)夠用(yong)(yong)于油(you)罐(guan)車腳(jiao)踏網(wang)、重(zhong)型機械及(ji)鍋(guo)爐、油(you)礦井(jing)、機車、萬噸輪(lun)船等(deng)的(de)(de)作(zuo)業途(tu)徑(jing)、扶梯、走(zou)道。也可作(zuo)為建(jian)筑業、公(gong)路(lu)、鐵路(lu)橋梁做鋼筋運(yun)用(yong)(yong)。
