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，工字钢价格，型号齐全，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，工字钢采购， 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)
选择胶合板主要看其甲醛释放量和胶合强度。如果胶合板的胶合强度不好，工字钢生产商，容易散架。选择时注意胶合板的标称厚度与实际厚度是否相符。

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.
