Aluminium Commercial Roller Shutter Slat Profile

The AR551 series slat is coated before forming, which ensures all metal surfaces are protected from corrosion. The shape of the profile has been designed specifically to suit the Commercial roller shutter market along with many Domestic applications. The slat is roll formed in the Adelaide manufacturing facility to the highest of world standards. The German built roll forming machine is the most advanced of its type in Australia today.

AR551 perforated slat


The base material has a two-coat system of primer plus topcoat, which is based on a polyurathane/polyamide binder. The polyester is cross-linked with melamine or blocked isocyanate resins and modified with Polyamide to provide the high resistance to abrasion.

Mechanical Properties:

The AR551 Commercial slat is a double walled cavity, curved 55mm profile with PU foam injected during the roll forming process. This process provides economical strength and insulation qualities while maintaining exceptional working performance of the slat. The curved shape of the slat provides minimal roll sizes and optimal lateral strength.

Nominal Thickness:

11.6mm Weight per sqm: 3.4kg.


The AR551 Commercial slat profile is expected to perform satisfactorily 20 years in normal climatic conditions, and when fitted under the specifications listed. During this period, normal weathering of the coating is expected with a reduction in gloss and a gradual uniform colour change over the lifetime of the coating. The coating of the AR551 series slat profile carries a nominal 5-year warranty against fading due to normal weathering conditions.
