The H steel is efficient and economic cutting surface profile (there are other cold-formed steel, steel etc.), owing to the section shape is reasonable, they can make the steel higher effectiveness, improve the bearing capacity. Different from the ordinary I-shaped flange type H steel was widened, and the internal and external surface is usually parallel, which can facilitate the connection with high strength bolts and other components. Its size to form a series of reasonable, model complete, easy to use design.

The scope of application

Ordinary I-beam, light I-beam, because the section size are relatively high, narrow, so themoment of inertia of the cross-section of two main sleeve difference, thus in their applicationrange is limited. The I-steel should be based on the requirements of design drawings for choice.

The size design

H steel is efficient and economic cutting surface of steel (there are other cold-formed steel,steel etc.), owing to the section shape is reasonable, they can make the steel higher effectiveness, improve load ability. Different from the ordinary I-beam is flange type H steelwas widened, and the inner and the outer surface is usually parallel, which can facilitate theconnection with high strength bolts and other components. The composition of a reasonablesize, model complete, easy to use design.

In structure design, selection of I-beam should be based on its mechanical properties,chemical properties, weldability, structure size and the reasonable choice of the I-beam touse.

Welding process

Flange type H steel are of equal thickness, a rolling section, there are composite section is composed of 3 blocks of plate welding composition. Ordinary I-beam are rolling section,because of the production process is poor, the flange edge 1:10 slope. H type steel rolling is different from ordinary I-beam with only one set of horizontal roll, because of its wide flangeand no inclination (or slope is very small), so it will be a group of vertical roll at the same timerolling, therefore, the rolling technology and equipment than the conventional mill complex.The maximum rolling H steel of domestic production can be the height of 800mm, more thanonly welding composite section.
