Q235 welded steel square pipe rectangular steel tube seamless adequate stock

Differences and advantages with traditional hot rolled square pipe:

1. Manufacturing process: The traditional hot-rolled square tube manufacturing process requires rolling and welding at high temperatures, while the cold-formed square tube manufacturing process is carried out at room temperature, so it consumes less energy, reduces the impact on the environment, and has better energy-saving and environmental protection characteristics.

2. Cost effectiveness: Although the cold-formed square pipe manufacturing process requires more cold-formed forming equipment, it can reduce production costs because there is no welding process, especially in mass production.

3. Performance advantages: Cold-formed square pipes are usually better in strength, toughness and corrosion resistance than hot-rolled square pipes due to work hardening during cold rolling and cold bending, thereby improving the service life and reliability of the product.

4. Size range: The size range of cold-formed square pipes is relatively wide, and more sizes of pipes can be produced to meet different needs.

5. Application field: Cold-bending square pipe is widely used in building structure, machinery manufacturing, furniture manufacturing and other fields, especially suitable for scenes with high appearance and dimensional accuracy requirements.

Specification:

Below is the specification of square steel pipe hollow section we can supply.

Material selection:

Carbon steel,Stainless steel,Aluminum alloy,Alloy steel.

The selection of the appropriate cold-formed square pipe material needs to consider the mechanical requirements of the application scenario, corrosion resistance, weight restrictions and other factors. In different fields, choosing the right material according to the actual needs can effectively improve the service life and performance of cold formed square pipe in the project.

Production process:

Raw material--material inspection--uncoiling--flattening--cutting&butt welding--loop storing--forming--welding--flatten weld joint--water cooling--straightening&sizing--pipe cutting with fixed length--product inspection.

Application case:

1. The longest walking glass bridge in Asia-Zhangjiajie Grand Canyon Glass Bridge: Design concept: The use of cold-formed square pipes as the main structural materials of the bridge, to achieve light and transparent, so that visitors have a feeling of "walking in the air". Technical features: The cold-formed square pipe manufacturing process ensures the strength and toughness of the pipe, while forming a complex curved shape, which is combined with the glass to form a unique bridge structure.

2. Roof of high-speed railway station-Nanning East Railway Station, China: Design concept: Using cold-formed square pipe as the supporting material of roof structure, to achieve large-span column-free design and create a sense of open space. Technical features: Cold-formed square pipe as a lightweight and high strength material, so that the roof structure can achieve a large span design, reducing the use of support columns.
