Custom Slit Narrow PPGI Steel Coil & Strip – Roll Forming Grade
Product Overview
Custom slit narrow pre-painted galvanized steel (PPGI) is manufactured by high-precision slitting of wide master coils, providing customized width specifications for roll forming, shutter manufacturing, profile production and other narrow-material applications. Built on DX51D/DX52D forming grade steel with quality paint coating, it delivers consistent forming performance and uniform surface finish for high-volume secondary fabrication. It is the ideal feedstock for roll formers, shutter manufacturers and metal product fabricators.
Why Choose CNB Slit PPGI?
Our in-house high-precision slitting lines process PPGI coils with dedicated coated-steel tooling to ensure clean, burr-free cut edges with no paint chipping or peeling. We can slit to any width from 50mm to 600mm with tight width tolerances, and can combine multiple widths in a single shipment to optimize material yield and shipping cost. All slit coils are inspected for width, edge quality and paint integrity before delivery.
