Aluminium doors

A real all-rounder

As a light metal, aluminium is an extremely versatile and recyclable material. The combination of tensile strength, stability and conductivity, as well as corrosion, UV and weather resistance makes it the raw material of choice for many architects. Aluminium does not rust or warp, even without any expensive surface treatment. It is therefore mainly suitable for doors with high-quality fittings.

Hinge systems for heavy-duty and entrance doors

Areas of application

Perfect frame: Function & design

Aluminium can absorb strong forces without tearing or breaking. So, as a material, it provides a high degree of security. Due to the low unladen weight, even fire and smoke protection doors with glass inserts can be implemented with aluminium, expanding the number of possible areas of application. Therefore, connections with different system profiles can be made with the ALPRO hinge system while emphasising certain features for a harmonious appearance. An ideal combination of functionality and aesthetics, especially for heavy-duty and entrance doors.
