H-shaped steel is a kind of economically efficient profile with more optimized section area distribution and more reasonable strength-to-weight ratio, which is named because its section is the same as the English letter “H”. Because all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used.

Basic introduction

H-shaped steel is a kind of economically efficient profile with more optimized section area distribution and more reasonable strength-to-weight ratio, which is named because its section is the same as the English letter “H”. Because all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used.

Structure introduction

H-shaped steel is a new type of economic construction steel. The section shape of H-beam is economical and reasonable, and the mechanical properties are good. When rolling, every point on the section extends more evenly and the internal stress is small. Compared with ordinary I-beam, H-beam has the advantages of large section modulus, light weight and metal saving, which can reduce the building structure by 30-40%. And because its legs are parallel inside and outside, the leg end is right Angle, assembly and combination into components, can save welding, riveting workload up to 25%. It is often used in large buildings requiring large bearing capacity and good cross-section stability (such as factories, high-rise buildings, etc.), as well as Bridges, ships, lifting and transportation machinery, equipment foundations, supports, foundation piles, etc.

Introduction

H-beams are divided into hot-rolled H-beams and welded H-beams (H), and hot-rolled H-beams are divided into wide flange H-beams (HW), middle flange H-beams (HM) and narrow flange H-beams (HN).

HW is H-shaped steel height and flange width are basically equal; It is mainly used for steel core column in reinforced concrete frame structure column, also known as stiff steel column; It is mainly used for columns in steel structures

HM is H-shaped steel height and flange width ratio of roughly 1.33~~1.75 mainly in steel structure: used as steel frame column in the dynamic load bearing frame structure used as frame beam; For example, device platform

HN is H-shaped steel height and flange width ratio is greater than or equal to 2, mainly used in beams; The use of I-beam steel is equivalent to HN section steel;

The main materials of H-shaped steel are Q235B, SM490, SS400, Q345, Q345B and so on.

Applied range

H-shaped steel is mainly used for beam and column members in industrial and civil structures.
