The Essential Foundation for Precision Roll Forming
In the modern steel construction industry, efficiency starts with the preparation of the raw material. The Xinnuo Automatic Slitting and Cut-to-Length Line is a high-performance solution designed to transform raw steel coils into perfectly leveled, precisely slit, and accurately cut sheets. This integrated line is the ideal choice for manufacturers producing roofing sheets, wall panels, and structural components who refuse to compromise on quality.

Integrated 3-in-1 Workflow: Leveling, Slitting, and Cutting
Why manage three separate machines when you can have one integrated system? Our line simplifies your production by combining:
- High-Precision Leveling: Our 7 to 9 roller system removes "coil memory" and internal stresses, ensuring that every sheet is perfectly flat. This is critical for high-speed roll forming where sheet flatness directly affects the final profile quality.
- Versatile Longitudinal Slitting: Equipped with adjustable alloy steel blades, our slitting unit can split a wide coil into multiple narrow strips in a single pass. This is perfect for producing flashings, ridge caps, and custom trim materials.
- Accurate Transversal Cutting: The hydraulic cutting unit, synchronized with a high-speed encoder, delivers clean, perpendicular cuts. With a tolerance of within ±0.5mm, material waste is virtually eliminated.




Core Technical Advantages
- 9CrSi Alloy Slitting Blades: Our blades undergo specialized heat treatment to reach a hardness of HRC60-62, ensuring they remain sharp through thousands of tons of steel processing.
- Smart Automation with PLC: Featuring Delta or Siemens PLC systems, the machine allows operators to set multiple batches of different lengths and quantities. The automation ensures consistent results regardless of the operator's experience level.
- Durable Engineering: The main frame is built from 350# H-beam steel with reinforced lateral supports. This provides a stable, vibration-free platform that ensures long-term accuracy and a service life exceeding 15 years.
- Surface Protection: Every roller is hard-chromed and polished to a mirror finish, preventing scratches on sensitive color-coated or galvanized surfaces.
