The ALU-1237 is often used on residential and commercial buildings where security is the primary concern. 
This is because it has a very aesthetically pleasing design and it is also made using an extruded profile, giving it greater strength and stability over regular lath.
Furthermore, this model of shutter can be upgraded, for a surcharge, in order to achieve a higher security rating – Secured by Design LPS1175 SR1 (see accreditations explained on our website).
Although not insulated, this product in its basic form offers a more secure way of covering your apertures than the ALU12-M411.
These roller shutters can come perforated or punched if required (see punched and perforated sections) and come white or brown as standard, but can be powder coated a number of colours for a surcharge.
This particular model caters to smaller openings and domestic properties.

You would generally see this used in:
  • Office doors & windows
  • Bars
  • Reception counters
  • Display areas
  • Shop fronts
  • Domestic properties
  • Garage doors
  • Van & Vehicle shutters
  • Large range of Aluminum shutters that offer a secure and weatherproof solution to safeguarding large or small openings.
  • Traditionally gives a better cosmetic appearance to that of a steel shutter.
