H型鋼的翼緣都是等厚度的，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，翼緣內(nèi)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(wú)斜度(或斜度很小)，故須增設(shè)一組立式軋輥同時(shí)進(jìn)行輥軋。

The flange of the H steel is equal thickness, has a rolling cross section, and a  section of 3 plates. The I-steel is the rolling section, and the inner edge of the flange has the 1:10 gradient.

The rolling of H steel is different from ordinary I-beam only with a set of horizontal rolls. Because of its wide flange and no slope (or very small slope), a group of vertical rollers should be set up and rolled at the same time.
