Custom Embossed Aluminum Sheet Coil Punching Cutting Slitting Shearing 1050 1060 3003 H14 0.2-6mm

Embossed aluminum is supplied as flat sheet or coiled strip with a raised stucco, orange peel, pebble or bar pattern rolled into the surface. The pattern hides handling marks, diffuses light, improves slip resistance and adds stiffness without adding weight. The real cost of embossed aluminum, however, is rarely the metal itself - it is the secondary processing that follows. Buyers who order full width coils and then sub-contract the punching, cutting, slitting and shearing usually lose 3 to 6 percent of the material to handling, double freight and re-packing.

We run all four operations in one plant, on the same line that produces the embossed surface. Coil goes in, finished blanks and narrow strip come out, and the mill test certificate travels with the same heat number. One purchase order, one tolerance standard, one loading plan.

CNC turret punching for ventilation louvres, mounting holes, cable entries and locating notches. Hole diameter from 3mm upward, position tolerance +/-0.2mm, burr height held under 0.1mm on the exit side. Punched parts are deburred and stacked flat, so downstream welding or riveting does not need rework.

Precision cut-to-length on flying shear and CNC guillotine lines. Sheet length from 200mm to 6000mm, length tolerance +/-0.5mm, squareness within 0.5mm per metre. Cut edges are straight and free of the wave that appear when embossed coil is cut on a light duty shear.

Narrow strip slitting from 1450mm master coil down to 20mm minimum width. Width tolerance +/-0.1mm, camber under 1mm per 2 metres, burr grade 3 or better. Oscillate wound or ribbon wound coils are available for automatic feeding lines, with paper or PE interleaving to prevent surface scuffing in transit.

Heavy gauge shearing from 0.2mm to 6.0mm. Straight blade shearing for rectangular blanks, notching and corner cut-outs for cladding panels and trim profiles. Sheared edges keep the embossed pattern intact and require no further edge treatment before installation.

• Material yield: nested punching and optimised slitting patterns cut scrap to under 3 percent on repeat orders.
• Single tolerance chain: pattern, thickness and blank dimension are controlled on one line, so assembly fit is predictable.
• Lower landed cost: processed parts ship as one consolidated lot instead of coil plus separate processing freight.
• Faster lead time: stock coil is processed and loaded within 7 to 10 working days, against 4 to 6 weeks for a coil-then-process route.
• Traceability: every finished blank carries the heat number and mill test certificate of the mother coil.

HVAC duct and plenum panels, refrigeration and cold storage liners, appliance back panels punched for cable routing, vehicle interior trim and anti-slip floor inserts, transformer and electrical enclosure covers, suspended ceiling tiles, caravan and container wall blanks, signage substrates and column cladding trims.

Because punching, slitting and shearing are done on the embossed surface rather than on flat sheet that is textured afterwards, the pattern continues cleanly to the cut edge and there is no exposed bare-metal line at the border of the part.

Coil is eye to sky or eye to wall on seaworthy wooden pallets, wrapped in VCI film, plastic film and steel strapping. Slit strip is interleaved with paper or PE film and wound on heavy duty cores. Punched and sheared blanks are stacked with interleaving boards, corner protected and banded in export crates. Container loading plans are issued before shipment so the buyer can confirm the split between coil, strip and blanks.

Stock coil processed to order: 7 to 10 working days. Custom punching with new tooling: 20 to 25 working days after drawing approval.
