Description

SHS Steel Square Hollow Section is a steel pipe with a square cross-section.

Diversity and application of SHS Steel Square Hollow Section
Square steel pipe, a steel pipe with a square cross-section, plays an important role in many fields such as construction, machinery manufacturing and steel structure engineering.

There are many types of square steel pipes, which can be divided into many types according to different manufacturing processes and specific uses. These different types of square steel pipes can show unique functions and advantages in their specific applications, providing reliable support and protection for various projects.

Classification of SHS Steel Square Hollow Section:

Classification by manufacturing process:
Hot-rolled SHS Steel Square Hollow Section:
The steel plate or steel strip is rolled into shape and welded by hot rolling process. It is characterized by high strength and good toughness, which is very suitable for large structures and high-load environments.

Cold-rolled SHS Steel Square Hollow Section:
The steel plate or steel strip is rolled into shape and welded by cold rolling process. Its advantages are high surface finish and high dimensional accuracy, which is very suitable for precision machinery and decoration engineering.

Cold drawn SHS Steel Square Hollow Section:

Based on the hot rolled steel pipe, it is further processed by cold drawing process. Its characteristics include high precision, excellent surface quality and excellent mechanical properties, which are very suitable for occasions with high precision requirements.

Welded SHS Steel Square Hollow Section:

It is made by welding steel plates or steel strips after rolling and forming.

According to different welding methods, it can be divided into high frequency welding (ERW) and arc welding. This kind of steel pipe has high production efficiency and low cost, and is widely used in general structures and engineering.

Seamless SHS Steel Square Hollow Section: It is made directly from the whole steel billet through extrusion, rolling and other processes. It is characterized by no welds and strong pressure bearing capacity, which is very suitable for occasions with high pressure and high precision requirements.

Classification by material:

Carbon steel square steel pipe: It is known for its high strength and affordable price. It is an ideal choice for construction and general structures.

Stainless steel square steel pipe: With excellent corrosion resistance and beautiful appearance, it is particularly suitable for high-demand environments and decorative projects.

Alloy steel square steel pipe: It has unique physical and chemical properties and is specially designed for special environments and high-demand projects.

Classification by surface treatment:
Galvanized square steel pipe:
Its notable feature is that the surface is covered with a layer of zinc to enhance corrosion resistance, which is particularly suitable for outdoor or corrosive environments.
Coated square steel pipe:
This type of steel pipe is coated with anti-corrosion or other special functional coatings on the surface to meet the unique needs of specific projects.

Classification by wall thickness:
Ultra-thick wall square tube, thick wall square tube and thin wall square tube
