工字鋼的邊長小，高度大，只能承受單方向的力。  H型鋼槽深，厚度大，可以承受兩個(gè)方向的力。

工字鋼只能用于橫梁，而H型鋼才能用于結(jié)構(gòu)的承重柱。

The length of the I-steel is small 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.

厚鋼板的鋼種大體上和薄鋼板相同。在品各方面，除了橋梁鋼板、鍋爐鋼板、汽車制造鋼板、壓力容器鋼板和多層高壓容器鋼板等品種純屬厚板外，有些品種的鋼板如汽車大梁鋼板（厚2.5~10毫米）

The steel of a thick steel plate is roughly the same as that of a thin steel plate. In all aspects, in addition to bridge steel plate, boiler steel plate, automobile made steel plate, pressure vessel steel plate and multilayer high pressure vessel steel plate, some varieties of steel plate such as car beam steel plate (2.5~10 mm thick)

裝飾材料分為兩大部分：一部分為室外材料，一部分為室內(nèi)材料。室內(nèi)材料再分為石材，板材、片材、型材、線材五個(gè)類型。

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.
