Do you know the specifications of angle steel?

Do you know the specifications of angle steel?

The ordering of import and export angle steel is generally based on the standards required in the application, and the steel grade is the corresponding carbon steel grade. Also, apart from the standard number, angle steel does not have a specific composition and performance series.

Performance characteristics of steel bars

Performance characteristics of steel bars

The process performance of steel bars includes many items, and different requirements can be put forward based on the characteristics of different products. For example, ordinary steel bars require bending and reverse bending (reverse bending) tests, and some prestressed steel materials require repeated bending, torsion, and winding tests.

How to install steel bars?

How to install steel bars?

In order to ensure the correct position of the steel bars, tie a horizontal bar or stirrup outside the vertical stress bar, and spot weld it to the vertical bar to fix the position of the wall and column bars. Use a wire hammer to correct the spot welding.

What is the performance of angle steel? What are the main uses?

What is the performance of angle steel? What are the main uses?

Q420B high-strength angle steel is mainly used in the power industry. As an alternative material to Q235 and Q345 angle steel, by improving the material strength, the design weight of the tower can be effectively reduced, thereby saving materials and reducing transportation and installation costs. It plays an extremely important role in ultra-high voltage transmission and transformation system towers such as 750kV and 1000kV. effect.
