What is the difference between I-Steel and H-section steel

Date:Nov 06, 2018


The edge of the I-steel flange is the thickening of the surface by the ventral plate, and the exterior is thin; The flange of H-section steel is equal section.

HW HM HN h is a generic term for H-section steel, and H-section steel is welded; HW HM HN is a hot-rolled



What is the difference between I-Steel and H-section steel


The use of I-steel is equivalent to HN steel;

1, work-shaped steel whether ordinary or light, because the section size is relatively high, narrow, so the cross section of two main sleeves of the inertial moment difference is large, therefore, generally can only be directly used in its webs in the surface of the bending of the member or will be composed of a lattice force member.

2, H-section steel belongs to the high-efficiency economic cutting profile (other also has cold curved thin-walled steel, pressure steel plate, etc.), because the cross-sectional shape is reasonable, they can make the steel more high efficiency, improve the ability to work. Unlike the Putong type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, which makes it easy to connect with high strength cinnamon and other components.

3, H-section steel flange are equal thickness, there is a rolling cross section, there are 3 pieces of plate welding composed of the combined cross section. I-Steel are rolling cross section, due to the poor production process, the flange side has a 1:10 slope. H-section steel rolling is different from ordinary I-steel only a set of horizontal roll, because its flange is wide and no slope (or small slope), so it is necessary to add a set of vertical roll at the same time roll rolling, therefore, its rolling process and equipment are more complex than ordinary rolling mill.
