The Square Tube Straight Forming Unit adopts advanced straight-forming technology, allowing direct shaping and rapid adjustment between different specifications.
Equipped with a highly automated intelligent mold-changing system, it enables efficient multi-size production with minimal manual intervention. This makes it especially suitable for manufacturers handling diverse orders, including small-batch and customized production.
Faster specification switching
Reduced tooling and labor costs
Improved production efficiency
Lower overall investment and operating costs
Aogang direct forming technology shapes steel strips directly into square or rectangular tubes without the traditional round-to-square process. This reduces edge wear, improves corner accuracy, ensures more uniform wall thickness, and helps save raw material during production.
The square tube mill machine uses heavy-duty sizing stands and optimized roller pass design to control deformation during forming. This ensures stable and precise R-angles that meet structural steel pipe production standards.
Aogang square tube mill machines use a quick-change roll system to reduce changeover time. Compared with traditional spacer adjustment methods, the roller replacement process is faster and helps improve production efficiency.
Yes. The same direct forming tube mill line can produce both square and rectangular steel pipes by adjusting the roller gap within the machine’s production range.
Reduces material consumption compared to traditional forming methods (typically up to 5%, depending on specifications).
Ensures precise corner radius for excellent appearance and enhanced strength.
Supports multi-size, small-batch production with minimal or no roller replacement.
Electric adjustment with intelligent control enables one-touch mold change and faster setup.
One set of rollers covers a wide range of specifications, reducing tooling and storage costs.
Optimized forming and welding ensure stable dimensions and higher overall tube strength.
