Precision Slit PPGI Prepainted Steel Coil Custom Cutting For Roll Forming Door Window Frame Profile Production Line

Combines high-quality prepainted galvanized steel with customized slitting operations to deliver exact-width coils ready for direct loading onto roll forming lines. Standard PPGI coils typically come in mill widths of 1000-1250mm, but most roll forming machines operate with specific width requirements. This slit-to-width service bridges the gap using CNC-controlled rotary slitting with ±0.1mm width tolerance. Integrated edge conditioning systems remove slitting burr and edge camber, producing flat, straight-sided slit coils that feed reliably through roll forming, press braking, and stamping operations.

• Precision Width Slitting: CNC-controlled rotary slitting with ±0.1mm tolerance ensures exact coil width compatibility with roll forming line tooling.
• Burr-Free Edge Quality: Integrated roller straightening removes slitting burr and edge camber, producing clean edges that feed smoothly without tool wear.
• Custom Width Capability: Slitting from minimum 30mm strip up to full mill width with single-width and multi-width programs for production requirements.
• Full Traceability: Each slit coil individually identified with parent coil traceability maintaining unbroken documentation chain from steel mill to finished product.
• Material Yield Optimization: Slit-to-width supply eliminates customer-side slitting scrap, reduces unused width inventory, and minimizes coil end losses.
• JIT Delivery Capability: Slitting programs scheduled for just-in-time delivery aligned with roll forming production schedules, reducing inventory costs.
