Ali Deck Uses The Qualicoat Powdercoat Process

BS 6496:1984: Specification for powder organic coatings for application and stoving to aluminium alloy extrusions, sheet and preformed sections for external architectural purposes, and for the finish on aluminium alloy extrusions. Ali-Deck extrusions are finished using the following EN standards:

EN 12206-1:2004: Paints and varnishes. Coating of aluminium and aluminium alloys for architectural purposes. Coatings prepared from coating powder

EN ISO 2409:2013: Paints and Varnishes, Cross Cut Test. Our quality department also perform the following tests on our powder coated profiles.

Curing Oven temperatures are checked and recorded on a daily basis External checks carried out by the powder suppliers and our Laboratory in Belgium on random samples of extrusion.

ISO9227: Acetic Acid Salt Spray Test

EN ISO 3231: Resistance to humid atmospheres containing Sulphur Dioxide

EN ISO 11341: Accelerated weathering test

EN ISO 2810: Natural weathering test (Florida Test). (Carried out on Powder type)

EN ISO 12206-1: Resistance to mortar (Carried out on Powder type)

EN ISO 6270-2: Constant Climate Condensation Water test Our aluminium is sent through a variety of pre-treatment chemical baths that remove a very fine layer off the surface before powder coating.

Our aluminium is sent through a variety of pre-treatment chemical baths that remove a very fine layer off the surface before powder coating.

QUALICOAT 2.1: Visual inspection at 3 metres for internal and 5 metres for external extrusions (Our Inspectors visually inspect at 1 metre as standard)

QUALICOAT 2.2: Gloss level check to within 5% +/- of the manufacturer’s stated level. [EN ISO 2813]

QUALICOAT 2.3: Thickness checks to see that the material is coated with at least 60 microns of powder, average. [EN ISO 2360]

QUALICOAT 2.4.1: Cross Hatch cuts are made at 2mm spacing with one being at 90° to the other cut, tape is then applied, left for 2 minutes and removed to check for adhesion of paint. [EN ISO 2409 2013]

QUALICOAT 2.6: Cupping test is carried out to check for adhesion with the substrate [EN ISO 1520]

QUALICOAT 2.7: Bend test on a 5mm Mandrel to ensure adhesion after bending [EN ISO 1519]

QUALICOAT 2.8: Impact test with an energy of 2.5Nm to ensure that the coating adheres to the substrate [EN ISO 6272 / ASTM D2794]

QUALICOAT 2.11: Machu test (Accelerated corrosion test) in a solution made up of Sodium Chloride, Acetic Acid and Hydrogen Peroxide at 37°C. Duration 48 hours

QUALICOAT 2.14: Polymerisation test (Wipe with MEK for 30 seconds)

QUALICOAT 2.16: Resistance to boiling water in a pressure cooker. Duration 1 hour 100Kpa

QUALICOAT 2.18: Sawing and drilling to ensure that there is no flaking after cutting (using sharp tools)
