H型钢属于经济裁面型材(其它还有冷弯薄壁型钢、压型钢板等)，由于截面形状合理，它们能使钢材更高地发挥效能，提高承裁能力。

H steel is an efficient and economical cutting section (other cold-formed thin-walled steel and profiled steel sheets). Because of the reasonable shape of the section, they can make the steel play a more effective role and improve the bearing capacity.

工字钢的边长小，高度大，只能承受单方向的力。 H型钢槽深，厚度大，可以承受两个方向的力。

工字钢只能用于横梁，而H型钢才能用于结构的承重柱。

The length of the I-steel is ***all and high. It can only bear the force of the single direction. The H steel groove is deep and thick, and can bear the force of two directi.

I-steel can only be used for crossbeams, and H steel can be used for structure bearing columns.

装饰材料分为两大部分：一部分为室外材料，一部分为室内材料。室内材料再分为石材，板材、片材、型材、线材五个类型。

Decorative materials are divided into two parts: one is outdoor materials, the other is indoor materials. Indoor materials are further divided into five types: stone, sheet, sheet, profile and wire.
