Examples of the use of square pipes, shaped pipes, and multi-tube pipes (square pipes, shaped pipes).
Cost reduction, design improvement, and procurement of special-sized square pipes are now possible!
When using two square pipes and welding square pipes with flat steel, converting to irregular pipes allows for (1) cost reduction (elimination of welding, elimination of welding finishing, elimination of labor for correcting thermal distortion) and (2) quality improvement (increased precision, improved surface texture)! The benefits of converting to irregular pipes are significant. For more details, please contact us.

Company information
We manufacture and sell square pipes (square tubes), shaped pipes (shaped tubes), and multi-layer pipes (multi-layer tubes) through cold roll forming processing from round tubes. There are various forming methods, including hot, warm, and cold forming, but among them, cold roll forming is characterized by its beautiful surface finish and the ability to form at a low cost compared to other methods. The pipe forming methods using forming rolls include the "extrusion roll method," where the base pipe (the pipe before forming) is pushed through the forming rolls; the "draw bench method," where the pipe is formed by pulling; and the "roll forming method," where the base pipe is advanced by driving the forming rolls. Nakayama Industries possesses these three methods, allowing us to select the optimal method to meet our customers' diverse needs. Furthermore, we create unique shaped pipes, square, shaped, and multi-layer pipes that are not produced by other manufacturers or cannot be made by them, tailored to the sizes and shapes requested by our customers, adding our proprietary technology. With our relentless technological development unique to Nakayama Industries and a reliable manufacturing method, we have earned immense trust from our customers.
