鋼(gang)(gang)板(ban)是鋼(gang)(gang)材四大品種（板(ban)、管(guan)、型、絲(si)）之一。
鋼板按厚(hou)度分為薄板和厚(hou)板兩大規(gui)格(ge)
薄(bo)鋼(gang)(gang)(gang)(gang)板(ban)是(shi)用熱(re)軋或冷軋方法(fa)生產的(de)厚度在0．2－4mm之(zhi)間的(de)鋼(gang)(gang)(gang)(gang)板(ban)。薄(bo)鋼(gang)(gang)(gang)(gang)板(ban)寬度在500－1800m之(zhi)間。根據不同的(de)用途，薄(bo)鋼(gang)(gang)(gang)(gang)板(ban)采(cai)用不同材質鋼(gang)(gang)(gang)(gang)坯軋制(zhi)而成(cheng)。通常(chang)采(cai)用材質有普碳(tan)鋼(gang)(gang)(gang)(gang)、優碳(tan)鋼(gang)(gang)(gang)(gang)、合金結構鋼(gang)(gang)(gang)(gang)、碳(tan)素工(gong)(gong)(gong)(gong)具(ju)鋼(gang)(gang)(gang)(gang)、不銹鋼(gang)(gang)(gang)(gang)、彈(dan)簧鋼(gang)(gang)(gang)(gang)和電工(gong)(gong)(gong)(gong)用硅鋼(gang)(gang)(gang)(gang)等(deng)。它們主要用于汽(qi)車工(gong)(gong)(gong)(gong)業(ye)(ye)、航空工(gong)(gong)(gong)(gong)業(ye)(ye)、搪瓷工(gong)(gong)(gong)(gong)業(ye)(ye)、電氣(qi)工(gong)(gong)(gong)(gong)業(ye)(ye)、機械工(gong)(gong)(gong)(gong)業(ye)(ye)等(deng)部門。薄(bo)鋼(gang)(gang)(gang)(gang)板(ban)除(chu)軋制(zhi)后直接交(jiao)貨(huo)之(zhi)外，還有經過酸洗的(de)、鍍(du)鋅和鍍(du)錫等(deng)。
厚(hou)(hou)(hou)鋼(gang)板(ban)(ban)(ban)(ban)(ban)是(shi)厚(hou)(hou)(hou)度(du)在(zai)4m以上的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)統稱(cheng)，在(zai)實際(ji)工作中，常將厚(hou)(hou)(hou)度(du)小于(yu)20m的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)稱(cheng)為(wei)(wei)中板(ban)(ban)(ban)(ban)(ban)，厚(hou)(hou)(hou)度(du)＞20mm至60mm的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)稱(cheng)為(wei)(wei)厚(hou)(hou)(hou)板(ban)(ban)(ban)(ban)(ban)，厚(hou)(hou)(hou)度(du)＞60mm的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)則需(xu)在(zai)專(zhuan)門的(de)(de)特厚(hou)(hou)(hou)板(ban)(ban)(ban)(ban)(ban)軋機上軋制(zhi)，故稱(cheng)特厚(hou)(hou)(hou)板(ban)(ban)(ban)(ban)(ban)，原(yuan)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)寬度(du)從1800mm－4000mm。厚(hou)(hou)(hou)板(ban)(ban)(ban)(ban)(ban)按用(yong)途又分(fen)造船鋼(gang)板(ban)(ban)(ban)(ban)(ban)、橋梁(liang)鋼(gang)板(ban)(ban)(ban)(ban)(ban)、鍋爐鋼(gang)板(ban)(ban)(ban)(ban)(ban)、高壓容器鋼(gang)板(ban)(ban)(ban)(ban)(ban)、花紋鋼(gang)板(ban)(ban)(ban)(ban)(ban)、汽(qi)車(che)鋼(gang)板(ban)(ban)(ban)(ban)(ban)、裝甲鋼(gang)板(ban)(ban)(ban)(ban)(ban)和復(fu)合鋼(gang)板(ban)(ban)(ban)(ban)(ban)等。
鋼(gang)板的一個分支是(shi)鋼(gang)帯(dai)，鋼(gang)帶實際(ji)上(shang)是(shi)很長(chang)的薄板，寬(kuan)度比較小(xiao)，常成(cheng)巻供應，也稱為帶鋼(gang)。鋼(gang)帶常在多機(ji)架連續式軋機(ji)上(shang)生產，切成(cheng)定(ding)尺長(chang)度后就是(shi)鋼(gang)帶。
