What are the characteristics of profile steel?

Light weight of the structure: Compared with the weight of the concrete structure, the weight of the structure is reduced, which reduces the internal force of the structure design, which can make the foundation processing requirements of the building structure lower, the construction is simple, and the cost is reduced.

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.

Rebar binding joints

The distance between the end of the lap length and the bending point of the steel bar shall not be less than 10 times the diameter of the steel bar. The joint should not be located at the maximum bending moment of the component.

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?

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.

What are the specifications of channel steel?

The delivery length of channel steel is divided into two types: fixed length and double length, and the tolerance value is specified in the corresponding standard. The length selection range of domestic channel steel is divided into three types: 5-12m, 5-19m, and 6-19m according to different specifications. The length selection range of imported channel steel is generally 6-15m.

What are the classifications of I-beams?

I-beams are mainly divided into ordinary I-beams, light I-beams and wide-flange I-beams. They are mainly used as important components of large-scale equipment such as crane equipment, bridge construction, train vehicles, large boilers, and scale components.

What is angle steel, what are its characteristics and uses?

Unequal angle steel, angle steel with two sides with different lengths. Unequal side angle steel is also divided into unequal side equal thickness angle steel and unequal side unequal thickness angle steel based on the difference in thickness of the two sides.
