              H型鋼是一種斷面力學性能較工字鋼優良的經濟型斷面鋼材,因其斷面的形狀與英文字母“H”相同而得名。熱軋H型鋼的翼緣比工字鋼寬、側向剛度大、抗彎能力強。同等規格下H型鋼理重較工字鋼輕。

              H steel is a kind of economical section steel with better section mechanical properties than that of I-steel. Because the shape of the section is the same as that of the English letter "H". The flange of hot rolled H steel is wider than that of I-steel, large lateral stiffness and strong bending resistance. Under the same specification, the weight of H steel is lighter than that of I-steel.


              工字鋼也稱為鋼梁(英文名稱 I Beam),是截面為工字形狀的長條鋼材。工字鋼分普通工字鋼和輕型工字鋼,H型鋼三種。工字鋼廣泛用于各種建筑結構、橋梁、車輛、支架、機械等。

              I-steel beam (also known as English name I Beam), is an H-shaped steel strip section. I-steel is divided into three kinds: ordinary I-steel and light I-steel, H type steel. I-steel is widely used in various architectural structures, bridges, vehicles, stents, machinery and so on.


              槽鋼分普通槽鋼和輕型槽鋼。熱軋普通槽鋼的規格為5-40#。經供需雙方協議供應的熱軋變通槽鋼規格為6.5-30#。槽鋼主要用于建筑結構、車輛制造、其它工業結構和固定盤柜等,槽鋼還常常和工字鋼配合使用。

              Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot rolled ordinary channel steel is 5-40#. The specification of hot rolled and variable channel steel supplied by both suppliers and suppliers is 6.5-30#. Channel steel is mainly used in building structure, vehicle manufacturing, other industrial structure and fixed disk cabinet, and channel steel is often used in conjunction with I-steel.
