Square Pipe Rolls are precision-engineered forming rolls used in ERW tube mills to manufacture square hollow sections (SHS). These rolls gradually shape round tubes or flat steel strips into square pipes with accurate dimensions, sharp corners, and excellent surface finish. They are designed to ensure consistent forming, proper weld alignment, and high production efficiency.

• Manufactured from premium-grade tool steels
  such as 02, H13, EN31, HCHCR, and other
  alloy steels.
• CNC-machined and precision-ground for
  superior dimensional accuracy.
• Heat-treated to achieve high hardness
  (58—62 HRC) for excellent wear resistance.
• Designed for smooth and uniform material
  flow during forming.
• Available in custom sizes to suit dierent square
  pipe dimensions, wall thicknesses, and tube
  mill models
• Suitable for high-speed production with
  long operational life.
