1、工字型钢不论是普通型还是轻型的，由于截面尺寸均相对较高、较窄，故对截面两个主袖的惯性矩相差较大，因此，济钢代理商一般仅能直接用于在其腹板平面内受弯的构件或将其组成格构式受力构件。对轴心受压构件或在垂直于腹板平面还有弯曲的构件均不宜采用，这就使其在应用范围上有着很大的局限。
1, I-steel whether ordinary or light, because the section size are relatively high and narrow, so the moment of inertia of the main sections of the two sleeve is large, therefore, Jinan agents generally can only directly used in the web plane bending member or the composition of lattice stress components. It is not suitable for the axial compression member or the bent member perpendicular to the web plane, which has great limitations in its application.

2、 h型钢属于高效经济裁面型材，济钢代理商由于截面形状合理，它们能使钢材更高地发挥效能，提高承裁能力。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桂和其他构件连接。其尺寸构成合理系列，型号齐全，便于设计选用。
2 and H section steel is a kind of economical and economical cutting section material. Because of the reasonable shape of cross section, they can make steel more effective and improve the ability of cutting. Unlike ordinary I-beam, the flange of H steel is widened, and the inner and outer surfaces are usually parallel, so that it can be easily connected by high strength spiral bolts and other components. Its size constitutes a reasonable series, complete model, easy to design and use.
3、h型钢的翼缘都是等厚度的，济钢代理商有轧制截面，也有由3块板焊接组成的组合截面。工字钢都是轧制截面，由于生产工艺差，翼缘内边有1：10坡度。H型钢的轧制不同于普通工字钢仅用一套水平轧辊，由于其翼缘较宽且无斜度，故须增设一组立式轧辊同时进行辊轧，因此，其轧制工艺和设备都比普通轧机复杂。
The flanges of the 3 and H sections are all of equal thickness. The agent of Jigang has a rolling section and a combined section composed of 3 plates welded together. I-beam is a rolling cross section, due to poor production process, flange within the edge of the 1:10 slope. H type steel rolling is different from ordinary I-beam with only one set of horizontal roll, because of its wide flange and no inclination, so a group of vertical roll and roll, therefore, the rolling process and equipment than the conventional mill complex.
