冷拔圓鋼外表面光滑，可塑性強(qiáng)，延展性能好，易于加工。冷拔圓鋼相比于市面上的其它鋼筋種類的區(qū)別主要體現(xiàn)在三個(gè)方面，通過(guò)以下內(nèi)容進(jìn)行說(shuō)明：<span style="font-size:12px;">1、外型不一樣，圓鋼外型光圓，無(wú)紋無(wú)肋，其它鋼筋表面外型有刻紋或有肋，這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。</span><span style="font-size:12px;">2、成份不一樣，圓鋼(一級(jí)鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。</span><span style="font-size:12px;">3、強(qiáng)度不一樣，冷拔圓鋼強(qiáng)度低，其它鋼強(qiáng)度高，即直徑大小相同的圓鋼與其它鋼筋相比，圓鋼所能承受的拉力要比其它鋼筋小，但圓鋼的塑性比其它鋼筋強(qiáng)，即圓鋼在被拉斷前有較大的變形,而其它鋼筋在被拉斷前的變形要小得多。</span> </p><div
