H steel

H steel

It is a kind of economic section steel with better mechanical properties, which is optimized and developed from I-section steel. Especially, the section is the same as the English letter "H", and it is divided into submerged arc welding H-section steel and high-frequency welding H-section steel.

Product definition

It is a kind of economic section steel with better mechanical properties, which is optimized and developed from I-section steel. Especially, the section is the same as the English letter "H", and it is divided into submerged arc welding H-section steel and high-frequency welding H-section steel.

Production technology

Submerged arc welding H-beam adopts the following technology: steel plate -- automatic slicing -- assembly -- automatic submerged arc welding -- flaw detection -- flange correction -- web correction -- end processing -- sand blasting -- rust removal -- spray painting. The automatic submerged arc welding production line is controlled by microcomputer from cutting, forming and welding, which ensures the dimensional accuracy of H-beam steel and the weld quality meet the national standards.

Product characteristics

Universal steel beam

H-beam is also called universal steel beam, wide-rim (edge) I-beam or parallel flange I-beam. The cross section of H-beam usually includes two parts: web and flange plate, also known as waist and side.

Parallel flanged I-beams

The inner and outer flanges of H-beams are parallel or nearly parallel, and the ends of the flanges are at right angles, hence the name parallel flanged I-beams.

Wide flange I beam

The thickness of the web of H-beam is smaller than that of ordinary I-beams with the same height of the web, and the width of the flange is larger than that of ordinary I-beams with the same height of the web, so it is also named wide rim I-beams.

Strength is better than ordinary I-steel

Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than that of ordinary I-beam with the same single weight.

Good carrying capacity

Used in different requirements of the metal structure, whether under bending moment, pressure load, eccentric load show its excellent performance, can greatly improve the bearing capacity than ordinary I-steel, metal saving 10% ~ 40%.

Use flexible, improve the speed of construction

H beam has wide flange, thin web, many specifications and flexible use, which can save 15% ~ 20% metal in various truss structures. Because the flange is parallel inside and outside, and the edge end is at a right Angle, it is easy to assemble and combine into various components, which can save about 25% of the welding and riveting work, and greatly accelerate the construction speed of the project and shorten the construction period.
