Narrow Prepainted Steel Coil (Small-Width PPGI / PPGL) – Width <600mm, Custom Slit Coils for Window Frames, Door Profiles & Steel Pipes
Product Overview
Not all prepainted steel is used in wide roofing sheets. Our narrow-width PPGI/PPGL coils are precision-slit from standard master coils into widths under 600mm (with specific HS code 72124000 for widths <600mm). These narrow strips are the preferred raw material for cold-roll-formed sections (e.g., C/Z purlins, window frames, door jambs, and automotive trim), as well as for spiral pipe wrapping and electrical conduit manufacturing. We supply them with the same premium paint systems (PE, SMP, HDP, PVDF) and corrosion-resistant substrates (GI or GL) as our full-width coils, ensuring color and quality consistency across your production line.
Specification Spotlight: Custom Slitting Width
We offer precision slitting down to 5mm width, with standard stocked widths of 100mm, 200mm, 300mm, 400mm, and 500mm. Tolerances are strictly controlled per international standards to ensure smooth roll-forming without edge burrs.

Core Advantages
Zero Waste – Slit exactly to your profile dimensions, reducing material scrap at your factory.
Color Consistency – All narrow coils are slit from the same master batch, ensuring no color variation between batches.
Fast Roll-Forming Feed – Narrow coils fit standard profile roll-formers with minimal tension adjustments.
Portable – Lighter coils are easier to handle and load onto small forming lines.
Applications
Building profiles: Window frames, door frames, garage door tracks, C/Z purlins.
Pipe industry: Spiral-welded pipe outer wrapping and protective sleeving.
Automotive: Decorative trims, weatherstrip retainers.
Electrical: Conduits and cable tray sections.
