Steel Profile Section Types, Applications (table)
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.

Specification
Uses
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

Specification
Uses
I-beam
The specifications are defined in height (H), the model number is 1/10 of the waist height, and the model number is 8 to 63, meaning the specification range is 80 to 630mm.
For buildings, bridges, and other metal structures
Channel steel
The specification is defined in height (H), and the model number is expressed in 1/10 of the height, and the general model number is 5 to 40, and the specification range is 50 to 400mm
For construction, bridge, and vehicle manufacturing
Z-beam
The specification is defined by the waist height (H)
For railroad vehicles, industrial buildings and agricultural machinery, etc.
