Channel steel: the backbone of buildings for multiple applications. Material and model selection guide

Channel steelis a long strip of steel with a groove shaped cross-section cast from ordinary carbon steel or low-Alloy Steel.

                                  


The role of channel steel in engineering is multifaceted.

Channel steelis a type of carbon Structural Steel used in construction and machinery. It is a complex section steel with a groove shaped cross-section.  
Channel steel is mainly used in building structures and vehicle manufacturing.
Channel steel is divided into hot-rolled channel steel and bent channel steel.
Hot rolled channel steel is divided into two types: ordinary and lightweight.
The specifications of channel steel are mainly expressed by dimensions such as height (h), leg width (b), waist thickness (d), etc
In use, it is required to have good welding, riveting performance, and comprehensive mechanical properties.
As a commonly used structural material, channel steel is widely used in fields such as construction, bridges, mechanical equipment, and ships.

It has the following important functions:

1. Structural support: Channel steel can be used for the main structure of buildings and the support structure of bridges.
Due to its high strength and stiffness, channel steel can withstand large loads and maintain structural stability.
In the field of architecture, channel steel is often used to construct load-bearing structures such as columns, beams, and crossbeams, ensuring the stability and safety of buildings.  
2. Bridge construction: Channel steel is widely used in the construction of bridges, including bridge piers, deck beams, and supporting structures.
The high strength and corrosion resistance of channel steel make it an ideal bridge material.
The shape design of the channel steel is reasonable, which can effectively reduce the weight of the bridge, improve the bearing capacity and seismic performance of the bridge.  
3. Mechanical manufacturing: Channel steel also plays an important role in the field of mechanical manufacturing.
It is often used to manufacture the skeleton, support, and connecting components of mechanical equipment.
The shape of channel steel can be adjusted according to different design requirements, providing flexibility and diversity, suitable for the manufacturing and assembly of various mechanical equipment.  
4. Shipbuilding: Channel steel plays an important role in shipbuilding.
It is widely used for the assembly and support of ship structures.
The high strength and good plasticity of channel steel enable ships to withstand the complex environment and impact of large waves at sea.  
In short, as a multifunctional structural material, channel steel plays an important role.
It undertakes tasks such as supporting structures, bridge construction, mechanical manufacturing, and shipbuilding in engineering.
Its superior physical properties and flexible shape design make channel steel an indispensable material in the engineering field.
Whether in construction, bridges, mechanical equipment, or shipbuilding, channel steel plays an important role in providing solid support for the stability, safety, and reliability of the project.

Characteristics of channel steel

(1) A thick and dense pure zinc layer covers the surface of the steel, which can prevent the steel substrate from coming into contact with any corrosive solution and protect the steel substrate from corrosion. In the general atmosphere, a thin and dense layer of zinc oxide is formed on the surface of the zinc layer, which is difficult to dissolve in water and therefore plays a certain protective role on the steel substrate.

(2) Featuring an iron zinc alloy layer and dense bonding, it exhibits unique corrosion resistance in marine salt spray and industrial atmospheres;

(3) Due to its strong bonding and zinc iron compatibility, it has strong wear resistance;

(4) Due to the excellent ductility of zinc, its alloy layer adheres firmly to the steel substrate, allowing hot-dip plated parts to be formed through various processes such as cold stamping, rolling, drawing, and bending without damaging the coating;

(5) After hot-dip galvanizing of steel structural components, it is equivalent to one annealing treatment, which can effectively improve the mechanical properties of the steel substrate, eliminate the stress during the forming and welding of steel components, and facilitate the turning processing of steel structural components.
