Introduction

H-beam is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H".Generally, narrow-flange H-shaped steel is used as the beam material, and wide-flange H-beam is used as the column material. Accordingly, it is also called beam-type H-shaped steel and column-type H-shaped steel.

Since all parts of H-beam are arranged at right angles, H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.

Classification

1.According to the flange width of the product:

(1)Wide flange H-beam:width(B)≥height(H)

(2)Medium flange H-beam:width(B)≥height(H)

(3)Narrow flange H-beam:width(B)＝1/2 height(H)

2.According to product use:

(1)H-shaped steel beams

(2)H-shaped steel columns

(3)H-shaped steel piles

(4)Extremely thick flange H-shaped steel beams

3.According to the production method:

(1)Welded H-beam

(2)Rolled H-beam

Welding H-shaped steel has the disadvantages of high metal consumption, difficulty in ensuring uniform product performance, and limited size specifications. Therefore, H-shaped steel is mainly produced by rolling method. In modern steel rolling production, universal rolling mills are used to roll H-shaped steel.

4.According to the size:

(1)Large H-beam:height(H)＞700mm

(2)Medium H-beam:700mm＞height(H)＞300mm

(3)Small H-beam:height＜300mm

Standard:AISI, ASTM, BS, DIN, GB, JIS etc.
