Section steel is a kind of steel with many varieties and specifications and a wide range of applications. It is mainly used to manufacture bridges, ships, vehicles, boilers, high-pressure vessels, and so on. Here in this post, we will mainly introduce the commonly seen section steels and their applications.

|
Square Steel |
 |
Its specifications are defined in terms of side length dimensions, with a side length of 5 to 250mm in general |
Parts for the manufacture of various types of equipment |
|
Round steel |
 |
Its specifications are defined in terms of section diameter. The diameter is generally 5 to 350mm. |
It is used for drawing steel wires, making wire ropes, metal nets, welding rods, welding cores, springs, nails, building reinforcement, bolts, mechanical parts, and raw materials for seamless steel pipes. |
|
Flat steel |
 |
The specifications are defined in terms of thickness and width. The thickness is 4-60mm, and the width is 10-200mm. |
Used as raw material for sheet and welded pipe, also used in machinery manufacturing |
|
Hexagonal steel |
 |
The specifications are defined in terms of the hexagonal inner joint circle diameter size. Usually, rolled hexagonal steel has an inner joint circle diameter of 7 to 80mm |
For the manufacture of nuts and tools |
|
Triangles |
 |
Specifications are expressed in terms of side length, from 9 to 30mm |
Mainly used for making files |
|
Bowed steel |
 |
The specifications are expressed by height and width; height is 5-12mm, width 15-20mm |
For vehicle leaf springs |
|
Oval steel |
 |
The long and short axis dimensions express the specifications, the long axis is 10-26mm, and the short axis is 4-10mm |
For parts, files |
|
equilateral Angle steel |
 |
The specifications are expressed in side length and side thickness, with side lengths from 20 to 200mm and side thicknesses from 3 to 20mm. |
For metal structures, bridges, machinery manufacturing |
|
Unequal angles |
 |
The specifications are expressed in terms of two side lengths |
For metal structures, bridges, machinery manufacturing |
