型材是铁或钢以及具有一定强度和韧性的材料（如塑料、铝、玻璃纤维等）通过轧制，挤出，铸造等工艺制成的具有一定几何形状的物体。按照钢的冶炼质量不同，型钢分为普通型钢和优质型钢。普通型钢按现行金属产品目录又分为大型型钢、中型型钢、小型型钢。普通型钢按其断面形状又可分为工字钢、槽钢、角钢、圆钢等。型号规格米重UB127*76*13127*76*4*7.613UB152*89*16152.4*88.7*4.5*7.716UB178*102*19177.8*101.2*4.8*7.919UB203*102*23203.2*101.8*5.4*9.323.1UB203*133*25203.2*133.2*5.7*7.825.1UB203*133*30206.8*133.9*6.4*9.630UB254*102*22254*101.6*5.7*6.822UB254*102*25257.2*101.9*6*8.425.2UB254*102*28260.4*102.2*6.3*1028.3U254*146*31251.4*146.1*6*8.631.1UB254*146*37256*146.4*6.3*10.937UB254*146*43259.6*147.3*7.2*12.743UB305*102*25305.1*101.6*5.8*724.8UB305*102*28308.7*101.8*6*8.828.2UB305*102*33312.7*102.4*6.6*10.832.8UB305*127*37304.4*123.4*7.1*10.737UB305*127*42307.2*124.3*8*12.141.9UB305*127*48311*125.3*9*1448.1UB305*165*40303.4*165*6*10.240.3UB305*165*46306.6*165.7*6.7*11.846.1UB305*165*54310.4*166.9*7.9*13.754UB356*127*33349*125.4*6*8.533.1UB356*127*39353.4*126*6.6*10.739.1UB356*171*45351.4*171.1*7*9.745UB356*171*51355*171.5*7.4*11.551UB356*171*57358*172.2*8.1*1357UB356*171*67363.4*173.2*9.1*15.767.1UB406*140*39398*141.8*6.4*8.639UB406*140*46403.2*142.2*6.8*11.246UB406*178*54402.6*177.7*7.7*10.954.1UB406*178*60406.4*177.9*7.9*12.860.1UB406*178*67409.4*178.8*8.8*14.367.1UB406*178*74412.8*179.5*9.5*1674.2UB457*152*52449.8*152.4*7.6*10.952.3UB457*152*60454.6*152.9*8.1*13.359.8)
