The extruded aluminium roller shutter doors for industrial use Alumir SF and Alumir DF are light, long-lasting and provide a good closure for limited locations.
It is a high quality door resistant to impact, that is manufactured with an extruded aluminium slat to provide lightness and functionality In the case of model Alumir DF, it includes a double reinforced slat, which means a more solid door, with some more insulation without losing the flexibility of the simple blade.
Its operation is reliable, safe by means of a photocell curtain, and having a long useful life. It has a modern design that allow peepholes to be included, increasing both visibility and light access, and a choice of different finishings (standard aluminium colour, anodized silver and white 9016, with the option of other RAL colours).
Optionally, the aluminium slat can be micro-perforated or die-cut (single slat only). On the other hand, the speed of the roller shutter can be increased by means of a frequency variator.
