Basic Characteristics

Shape characteristics: The unique cross-sectional shape of U-shaped steel gives it excellent load-bearing capacity and stability.

Materials and standards: The materials and standards of U-shaped steel vary by country and region, but generally have high strength and rigidity. The national recommended standard for U-shaped steel produced in our country is GB/T 4697-2008, which was implemented on April 1, 2009.

Variety and specifications: U-shaped steel has various varieties and specifications, such as cold-formed U-shaped steel, large-sized U-shaped steel, automotive specific U-shaped steel, hot-dip galvanized U-shaped steel, etc. The main types of U-shaped steel produced in our country include 18U, 25U, 29U, 36U, and the newly added 40U, with different single weights and positioning methods for each type.

Main Uses

Mine roadway support: U-shaped steel is one of the main materials for mine roadway support. Its characteristics of high pressure bearing, long support time, easy installation and deformation resistance make it an ideal choice for mine roadway support.

Architecture and Civil Engineering: In the field of architecture and civil engineering, U-shaped steel is widely used to manufacture various steel structures such as buildings, bridges, tunnels, etc. Its high strength, high rigidity, and excellent seismic performance can ensure the stability and safety of building structures.

Mechanical manufacturing: U-shaped steel is also used to manufacture various key components of machinery, such as cars, trains, aircraft, and machinery. Its characteristics of high strength, high rigidity, and high corrosion resistance can meet various needs in the field of mechanical manufacturing.

Advantages and Characteristics

Strong load-bearing capacity: U-shaped steel has a narrow bottom and high edges on both sides, making it have good load-bearing capacity.

Good compressive performance: U-shaped steel has a special shape, which can better disperse stress when under pressure and effectively resist external forces.

Strong corrosion resistance: Some U-shaped steel varieties have undergone anti-corrosion treatment such as hot-dip galvanizing, which has excellent corrosion resistance and can be used for a long time in harsh environments.

Easy installation: The installation process of U-shaped steel brackets is relatively simple, which can save labor and time costs.

Application Instance

In mine tunnels, U-shaped steel supports are used to support and stabilize the tunnel walls, preventing the occurrence of surrounding rock collapse and roof collapse accidents.

In the field of construction, U-shaped steel is used to manufacture key components such as steel structural frames, beams, and columns, ensuring the overall stability and safety of buildings.

In the field of civil engineering, U-shaped steel is used to construct supporting structures for infrastructure such as bridges and tunnels, bearing the pressure from loads such as vehicles and pedestrians.
