Color Coated Aluminum Coil 25 Micron PVDF Precision Slitting 20-1600mm Flatness Controlled 0.2-3.0mm

A pre-painted aluminum coil built for fabricators who cannot afford gauge drift, edge wave or coating variation. Coating thickness is held within a narrow band across the full coil length, slit width is set to your line requirement down to the millimetre, and flatness is controlled coil set to coil set so the material runs through roll forming, punching and bending without rework.

• Precision slit width: coils supplied to your exact running width with burr free slit edges, so the profile forms to dimension without trimming on site.
• Flatness and coil set control: camber and edge wave controlled on a tension levelling line, so the coil unwinds flat and does not telescope in the uncoiler.
• Stable coating thickness: coating weight checked across the full coil length, not only at the head, so colour and gloss stay consistent from first metre to last.
• Production capacity behind the order: melting, hot rolling, cold rolling and coil coating all run in house, so custom slit orders are not queued behind outsourced processing.
• Alloy and coating choice: 1050, 1060, 1100, 3003, 3004, 3105, 5005, 5052 and 5754 substrates with PE, HDP, PVDF or FEVE coating systems.

The combination of stable coating thickness, tight slit width and flat material suits continuous production lines where a single out of tolerance coil stops the whole run.

• Corrugated and trapezoidal roof sheet forming, where edge wave shows up immediately as oil canning on the finished panel.
• Standing seam and concealed fix panels requiring camber control over long lengths.
• Sandwich panel facing, where coating thickness drives the guarantee period offered to the end client.

• Seamless gutter roll forming on site, where slit width tolerance sets the finished profile dimensions.
• Downpipe, fascia and flashing production from narrow slit coil.

• Aluminium ceiling tile and baffle production with RAL matched colour across repeat orders.
• ACP and composite panel skins requiring flat sheet and consistent gloss.

• Refrigeration, air conditioning and ventilation housings where paint adhesion and bend performance matter.
• Lighting reflectors and electrical enclosures built from narrow precision slit coil.

Every line below is available as standard or built to order, so this table is also the customization matrix. The Key Features above are quantified here.

• Melting and casting: 41 casting rolling machines feeding the rolling lines in house.
• Hot rolling: one 1850 double coil hot rolling mill for consistent upstream gauge.
• Cold rolling: nine cold rolling lines with crown and flatness control, which is where coil set and camber are decided.
• Coating: one 260 metre continuous coil coating line for uniform coating thickness and colour over the full coil.
• Plant scale: 780,000 sqm facility with 2,000 employees, allowing large programmes to run alongside custom slit orders.

Beyond the dimensional and coating options in the table above, we handle the branding, sampling and packing customization that distributors need to sell under their own name.

• Printing: logo, specification and handling marks printed on the coil eye or on the pallet label.
• Private label: OEM and ODM programs from artwork to carton and pallet design.
• Sampling: free A4 colour swatch, then a pre production coil signed off on coating thickness, gloss and slit width before the run.
• Packing format: pallet configuration, eye to sky or eye to wall loading and mixed width plan matched to your container.

• Technical consultation: share your forming line, profile drawing and target colour, and our engineers recommend alloy, temper and slit width.
• Documentation package: ASTM B209 mill certificate, coating thickness and adhesion reports, salt spray report and ISO 9001 certificate with each shipment.
• Colour management: retained colour standard per customer so repeat orders match the previous batch.
• Third party inspection: SGS, BV or Intertek inspection arranged at the factory before shipment on request.
• After sales: quality claims answered within 24 hours, with replacement or credit for any confirmed specification deviation.

• Coil packing: VCI anti corrosion film, waterproof paper and steel or plastic strapping, with edge protectors on both faces.
• Pallet loading: fumigation free plywood pallet, eye to sky or eye to wall as your uncoiler requires.
• Container capacity: around 20 - 25 tons per 20GP depending on coil weight and width mix, loading plan supplied before booking.
• Ports and terms: shipped from Qingdao, Tianjin or Shanghai under FOB, CIF, CFR or DDP terms.
• Lead time: 7 - 15 working days for stock gauge and stock colours, 20 - 30 working days for custom colour or custom slit width.
• Documents: commercial invoice, packing list, bill of lading, mill certificate, certificate of origin and insurance certificate issued per order.
