Machine manufacturing structure pipe

Large diameter square and rectangular steel pipes play a crucial role in providing structural support for infrastructure, construction, and industrial applications.

Large Diameter Square and Rectangular Hollow Section Manufacture Process

The direct square forming process involves bending the strip steel from the first unit, and through step-by-step extrusion and bending, the basic shape of the product is formed before welding. This process is commonly used in the production of square and rectangular steel pipes to meet specific structural and design requirements. The direct square forming process requires specialized equipment and technology to ensure the dimensional accuracy and structural strength of the products.

Strict Quality Control:
1) During and after production, 4 QC staffs with more than 5 years experience inspect products in random.
2) National accredited laboratory with CNAS certificates
3) Acceptable inspection from third party appointed/paid by buyer, such as SGS, BV.
4) Approved by Malaysia, Indonesia, Singapore, Philippines, Australia, Peru and UK. We own UL /FM, ISO9001/18001, FPC, CE certificates
