1、工字型鋼不論是普通型還是輕型的，由于截面尺寸均相對較高、較窄，故對截面兩個主袖的慣性矩相差較大，因此，濟鋼代理商一般僅能直接用于在其腹板平面內受彎的構件或將其組成格構式受力構件。對軸心受壓構件或在垂直于腹板平面還有彎曲的構件均不宜采用，這就使其在應用范圍上有著很大的局限。
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型鋼屬于高效經濟裁面型材，濟鋼代理商由于截面形狀合理，它們能使鋼材更高地發揮效能，提高承裁能力。不同于普通工字型的是h型鋼的翼緣進行了加寬，且內、外表面通常是平行的，這樣可便于用高強度螺桂和其他構件連接。其尺寸構成合理系列，型號齊全，便于設計選用。
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型鋼的翼緣都是等厚度的，濟鋼代理商有軋制截面，也有由3塊板焊接組成的組合截面。工字鋼都是軋制截面，由于生產工藝差，翼緣內邊有1：10坡度。H型鋼的軋制不同于普通工字鋼僅用一套水平軋輥，由于其翼緣較寬且無斜度，故須增設一組立式軋輥同時進行輥軋，因此，其軋制工藝和設備都比普通軋機復雜。
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.
