Master tinplate jumbo coil is a wide width electrolytic tin coated steel coil supplied for slitting service centers that cut material down to customer strip widths. Buying full width jumbo coils lets slitters minimise edge trim and reduce landed cost.
The coil is produced with consistent gauge, coating weight and flatness across the full 1250 mm width so that every slit strip meets the same specification.

Master tinplate jumbo coil is used by slitting and shearing service centers supplying can makers, packaging converters and metal stampers with cut strip and sheet.
It also suits large volume manufacturers of cans, closures and drawn parts that operate their own slitting or blanking lines.
Packaging & Quality AssuranceJumbo coils are eye to sky wound, wrapped with moisture proof paper and VCI film, strapped with galvanised banding and loaded into containers on seaworthy pallets.
Each coil carries a full heat traceable label with dimensions, weight, temper and coating weight, backed by mill certificates and optional third party inspection.
