槽钢的原料钢坯为含碳量不超过0.25%的碳结钢或低合金钢钢坯。成品槽钢经热加工成形、正火或热轧状态交货。其规格以腰高*腿宽(b)*腰厚(d)的毫米数表示，圣霖国际工字钢厂家，如150*78*9。

The raw billet of the channel steel is a carbon steel or low alloy steel billet containing less than 0.25% carbon content. The finished channel steel is delivered by hot forming， normalizing or hot rolling. Its specificati*** are represented by the millimeter number of waist height (H) * leg width (b) * waist thickness (d)， such as 150*78*9.

工字钢的边长小，圣霖国际工字钢生产，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.

不同于普通工字型的是H型钢的翼缘进行了加宽，且内、外表面通常是平行的，这样可便于用高强度螺栓和其他构件连接。其尺寸构成合理系列，圣霖国际工字钢，型号齐全，圣霖国际工字钢价格，便于设计选用。（除了吊车梁用工字型钢）。

Unlike the ordinary I-type， the flange of H steel is widened， and the inner and outer surfaces are usually parallel， so that it can be easily connected with high-strength bolts and other components. Its size is a reasonable series， and the model is complete， which is convenient for the design. (except for crane girder with I-type steel)
