Whether you’re looking to slit GI coils into narrow strips for ducting or require custom-width CRCA strips for automotive components, our team ensures tight tolerance and burr-free edges every time.

What is Coil Slitting?

Coil slitting is a metal processing service that cuts wide master coils into narrower coils with precise width requirements. This is essential for industries like automotive, fabrication, roofing, electrical panel manufacturing, and more, where input materials must match specific equipment and design specs.

Types of Coils We Slit

We are capable of slitting a broad variety of steel coils to serve multiple industry segments:
• HR Coils – Hot rolled coils, often used in structural and industrial applications.We handle various thicknesses and grades, including IS 2062 E250 and E350.
• HRPO Coils – Hot rolled pickled and oiled coils, ideal for applications needing a cleaner, scale-free surface.
• CRCA Coils – Cold rolled close annealed coils, known for their smooth finish and precision tolerance. Commonly used in electrical enclosures and white goods.
• Galvanized Iron (GI) Coils – Available in:
  o Zero Spangle GI Coils – Sleek finish, perfect for visible or aesthetic applications like ducting, cabinetry, and appliances.
  o Small Spangle GI Coils – For general construction and fabrication.
  o Heavy GSM Galvanized Coils – With zinc coating thicknesses from 80 GSM up to 200 GSM, based on corrosion resistance requirements.
