Diamond Grille Barrier Doors

Alspec Diamond Grille Security Doors


This product comes with a 7 year powder coat warranty.

Aluminium Frame

With an extruded aluminium frame that is built to order, you can have peace of mind that this product will fit your door opening perfectly, whether you require it as a hinged or sliding door.

Aluminium Security Grille

The grilles on these Diamond Grille Barrier Doors are manufactured to a standard 7mm thickness.


Diamond Grille Barrier Doors can be shipped with a standard insect mesh to keep bugs from passing through the gaps in the grille, or you have the option of a One Way Mesh, ideal if added privacy is required. One Way Mesh allows you to see out through your door at the same time as reducing the visibility into your house from the outside.

Single-Point Locking System

This product is fitted with a single-point locking system, but it can be upgraded with a three-point locking system for premium security. Check out our Diamond Grille Security Doors for more information.
