About Willy Naessens Alu

Aluminium window and door frames specially designed for industrial construction

Willy Naessens Alu bears the hallmark of the Willy Naessens Group. The company was vertically integrated into the group from the very beginning in 2010. Long and sometimes irregular delivery terms for aluminium building materials threatened the plans for large projects. For Willy Naessens, complete on-time delivery is nonnegotiable, so the decision was taken to set up in-house aluminium fabrication facilities.

Furthermore, to a certain degree Willy Naessens Alu applies the prefab principle to the world of aluminium. This means that, wherever possible, aluminium products are fabricated and finished in the workplace. This is one factor among others that helps ensure delivery and assembly terms are as much as half the market average.
