工(gong)(gong)(gong)字(zi)(zi)鋼(gang)也稱(cheng)為鋼(gang)梁（英文名稱(cheng) Universal Beam)，是截(jie)面為工(gong)(gong)(gong)字(zi)(zi)形狀(zhuang)的(de)長條(tiao)鋼(gang)材。工(gong)(gong)(gong)字(zi)(zi)鋼(gang)分普通工(gong)(gong)(gong)字(zi)(zi)鋼(gang)和(he)輕型(xing)工(gong)(gong)(gong)字(zi)(zi)鋼(gang)。是截(jie)面形狀(zhuang)為工(gong)(gong)(gong)字(zi)(zi)型(xing)的(de)型(xing)鋼(gang)。

工(gong)(gong)字(zi)(zi)鋼(gang)主要分(fen)為(wei)普通(tong)工(gong)(gong)字(zi)(zi)鋼(gang)、輕(qing)型工(gong)(gong)字(zi)(zi)鋼(gang)和寬翼(yi)緣工(gong)(gong)字(zi)(zi)鋼(gang)。按(an)翼(yi)緣與腹板(ban)高(gao)度(du) 比又分(fen)為(wei)寬幅(fu)、中(zhong)幅(fu)、窄幅(fu)寬翼(yi)緣工(gong)(gong)字(zi)(zi)鋼(gang)。前二者(zhe)生產(chan)的規格為(wei)10—60號，即 相應(ying)的高(gao)度(du)為(wei)10 cm—60 cm。在(zai)相同高(gao)度(du)下，輕(qing)型工(gong)(gong)字(zi)(zi)鋼(gang)翼(yi)緣窄、腹板(ban)薄、重 量輕(qing)。寬翼(yi)緣工(gong)(gong)字(zi)(zi)鋼(gang)又稱H型鋼(gang)，斷(duan)面特點是(shi)兩腿平行，且腿內側沒有斜(xie)度(du)。 它(ta)屬于(yu)經濟斷(duan)面型鋼(gang)，是(shi)在(zai)四輥萬能(neng)軋(ya)機上(shang)軋(ya)制的，所以又稱“萬能(neng)工(gong)(gong)字(zi)(zi)鋼(gang)”。普通(tong)工(gong)(gong)字(zi)(zi)鋼(gang)、輕(qing)型工(gong)(gong)字(zi)(zi)鋼(gang)已經形成(cheng)國家標準。
