What aluminum coil does Primealux Alloys supply?
Mill-finish, prepainted, and stucco-embossed aluminum coil in 1xxx, 3xxx, 5xxx series alloys, plus slitting and cut-to-length processing. Every order is sourced and produced to spec, not pulled from standing stock.
Mill-Finish Aluminum Coil
Uncoated coil for further processing, coating, or fabrication.

Coated coil in any RAL or custom color, across all coating systems.
View detailsStucco-Embossed Aluminum Coil
A repeating texture rolled into the surface during production, mill-finish or coated.
View detailsSlitting & Cut-to-Length
Coil slit to specified line widths with clean edges, or cut to length.

Gauge to scale
Gauge is easy to specify and hard to picture. Compare it against a credit card.
0.60 mm is 1.3x thinner than a standard credit card (0.76 mm).

A 3105-alloy substrate with PUPA coating supports up to roughly 75% recycled content without compromising the finish, confirmed per order.
How is coated coil quality tested?
Coated coil is tested against this panel before it ships. Material certificates accompany every batch; test reports and ASTM/EN references are available on request.
Salt spray
Corrosion resistance: critical for coastal and exterior use.
UV / accelerated weathering
Predicts color and gloss retention, and chalking resistance.
T-bend
Confirms the coating flexes without cracking when the coil is formed.
Impact resistance
Coating stays adhered under sudden deformation.
Adhesion (cross-hatch test)
Coating bonds to the substrate.
Gloss retention
Tracks finish appearance over time.
Abrasion resistance
Coating withstands surface wear.
MEK rub
Confirms cure and solvent resistance.
Pencil hardness
Measures coating hardness.
Color difference (delta E)
Confirms color consistency batch to batch.
Dry film thickness
Confirms the coating meets its specified thickness.
