Stainless Steel H-beam Introduction

H-beam is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named after its section is the same as the English letter "H". Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.

H-beam is a new type of economical construction steel. The section shape of H-beam is economical and reasonable, with good mechanical properties. During rolling, the extension of each point on the section is relatively uniform and the internal stress is small. Compared with ordinary I-beam, it has the advantages of large section modulus, light weight and metal saving, which can make buildings The structure is reduced by 30-40%; because the inside and outside of the legs are parallel, and the legs are at right angles, they can be assembled into components, which can save welding and riveting workload by 25%. It is often used in large buildings (such as workshops, high-rise buildings, etc.) that require large bearing capacity and good section stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, supports, foundation piles, etc.

The difference between I-beam HW HM Hn H-beam

HW HM HN H is the general name of H-beam, H-beam is welded; HW HM HN is hot rolled
HW is that the height and flange width of H-beam are basically equal; it is mainly used for steel core columns in reinforced concrete frame structure columns, also known as rigid steel columns; it is mainly used for columns in steel structures
HM is the ratio of the height of the H-beam to the width of the flange, which is roughly 1.33~1.75. Mainly in steel structures: used as steel frame columns and used as frame beams in frame structures under dynamic loads; for example: equipment platforms
HN is the ratio of H-beam height and flange width greater than or equal to 2; mainly used for beams;

The use of I-beam is equivalent to HN-beam;
1. Whether the I-beam is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main sleeves of the section is quite different. Therefore, it can generally only be directly used in its web. A member that is bent in a plane or is composed of a lattice-type stress member. It is not suitable to use axial compression members or members that are perpendicular to the plane of the web and bend, which makes it very limited in the scope of application.
2. H-beams are high-efficiency and economical cutting profiles (others include cold-formed thin-walled steels, profiled steel plates, etc.). Due to their reasonable cross-sectional shapes, they can make the steel perform better and improve the cutting capacity. Different from the ordinary I-shaped, the flange of the h-shaped steel is widened, and the inner and outer surfaces are usually parallel, so that it is convenient to connect with other components with high-strength screws. Its size constitutes a fair series, and the models are complete, which is convenient for design and selection.
3. The flanges of the h-beam are all of equal thickness, with a rolled section and a combined section composed of three welded plates. I-beams are all rolled sections. Due to poor production technology, the inner edge of the flange has a 1:10 slope. The rolling of H-beam is different from that of ordinary I-beam, which only uses one set of horizontal rolls. Because its flange is wide and has no slope (or small slope), it is necessary to add a set of vertical rolls for rolling at the same time. , its rolling process and equipment are more complicated than ordinary rolling mills. The maximum height of rolled H-beam that can be produced in China is 800mm, which exceeds the only welded composite section.

Stainless Steel Channel Application

H-beams are mainly used for beam and column members in industrial and civil structures.

◆Steel structure load-bearing brackets for industrial structures
◆Steel piles and supporting structures for underground works
◆Structure of industrial equipment such as petrochemical and electric power
◆Large-span steel bridge components
◆Ship and machinery manufacturing frame structure
◆Girder brackets for trains, cars and tractors
◆Port conveyor belt, high-speed baffle bracket

H-beams are widely used and are mainly used for: various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent seismic activity and high temperature working conditions; requiring large bearing capacity and cross-section Large bridges with good stability and large span; heavy equipment; highways; ship skeletons; mine support; foundation treatment and embankment engineering; various machine components.
