H型钢，是一种截面面积分配更加优化、强重比更加合理的经济断面型材，因其断面与英文字母“H”相同而得名。H型钢的两条外边内侧没有斜度，是平直的。这使得H型钢的焊接拼接比工字钢操作简单，单位重量的力学性能更好，可以节省大量的材料和施工时间。

H steel is a more efficient and economical section with high section area distribution, because its section is the same as the English letter "H". The two sides of the H type steel h***e no slope inside the inner side, and they are straight. This makes the welding and splicing of H steel simpler than I-steel, better mechanical properties per unit weight, and can s***e a lot of material and c***truction time.

板材是指一般的压型钢板\平板等,都是较薄的钢板,通常都作为屋面或围护墙等用型材是指热轧的\冷弯的如工字钢\H钢\C型钢Z型钢,通常都作主结构用。

Plate refers to the general profiled steel plate, flat plate, etc., which are thin steel plates, usually used as roofing or retaining walls.

Profiles refer to hot rolled cold-formed ones, such as I-steel, \H steel, \C steel and Z section steel, which are usually used for main structure.
