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，可以承受兩個方向的力。

工字鋼只能用于橫梁，而H型鋼才能用于結構的承重柱。

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.

槽鋼分普通槽鋼和輕型槽鋼。熱軋普通槽鋼的規(guī)格為5-40#。經(jīng)供需雙方協(xié)議供應的熱軋變通槽鋼規(guī)格為6.5-30#。槽鋼主要用于建筑結構、車輛制造、其它工業(yè)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.

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)
