HRPO (Hot Rolled Pickled & Oiled) Steel

HRPO steel is processed to remove scale and oxidation, resulting in a smooth, clean surface with enhanced corrosion resistance. It offers improved weldability, formability, and durability, making it ideal for automotive components, construction, and heavy machinery manufacturing.

Key Features of HRPO Steel

Good Strength

Ensures durability and performance in structural and industrial applications.

Excellent Weldability

Allows easy welding without compromising the material's integrity.

Superior Formability

Enables shaping and bending to suit diverse manufacturing needs.

Applications of HRPO products
  • Automobiles
  • Telecommunications
  • Engineering and Fabrication
  • Aerospace
  • Furniture
  • Drums and Barrels
