工字鋼的邊長(zhǎng)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.
