Square Pipe
Cost effectiveness: Long service life and low maintenance.
Stability: Because its shape provides stability, it is suitable for applications where rigidity and support are critical.
Easy to manufacture: Easily cut, weld and manipulate to create custom shapes and configurations.
Recycling capacity: Recyclability is very important for the sustainability of steel materials, reducing the impact on the environment.
The hot-rolled or cold-rolled coil is cold-formed, and then high-frequency welding is performed to make a square steel pipe.
It has a larger cross-sectional area and can withstand greater pressure and load, making it widely used in various fields such as steel structure engineering, power station equipment, lifting and transportation machinery, power plants, agriculture, and chemical machinery.
