Precision Slit Carbon Steel Coil and Carbon Steel Strip with 0.1mm Width Tolerance and 20-600mm Slit Width for Roll Forming

The precision slit carbon steel coil service turns wide master coils into narrow strip with the geometry accuracy that continuous production lines require. Zhengde operates multi-head slitting lines with laser-guided width setting, producing strip from 20mm to 600mm wide with a width tolerance of ±0.1mm and burr below 0.05mm. Camber is controlled to 1mm per 2m so strip feeds straight into roll forming, punching and tube mills without twisting. Base materials cover Q195, Q235, SPCC, DC01 and SS400 in thicknesses from 0.3mm to 6.0mm, and tension leveling can be added where extreme flatness is specified. Each slit coil is wrapped and strapped on a steel skid, and a release report records the measured width, burr and surface condition of every order.

• Tight Width Tolerance — Modern slitting heads with laser alignment hold width within ±0.1mm so roll formed profiles stay dimensionally stable across the full production run.
• Deburred Clean Edges — Controlled clearance and tooling condition keep burr below 0.05mm, protecting rollers and eliminating secondary deburring stations.
• Controlled Camber — Low camber strip prevents twisting and wandering in high-speed roll forming and punching machines.
• Edge Protection — Oil coating and protective wrapping keep slit edges rust-free during storage and shipping.
• Flexible Sizes — Multiple slit widths from one master coil cut inventory cost and shorten lead time for profile makers.
• Material Versatility — Mild steel and cold rolled grades in one service point simplify procurement for shutter, purlin and tube producers.

Precision slit coils feed continuous production lines that demand constant strip geometry: rolling shutter curtain profiles, louver blades and window guides, purlin and rail roll forming, cable tray sections, furniture edge trims, steel strapping, fence posts and tube blank preparation. Component stampers also use narrow slit strip for brackets, hinges and clips where consistent width protects tool life.

Each slit order is dimension checked on line and documented with a release report covering width, burr and surface condition. Zhengde operates under ISO 9001:2015, and material certificates follow the base coil heat. Coils are strapped on steel skids with edge protectors for export. Typical delivery is 7–15 days depending on slitting schedule and quantity.
