Heritage Diamond Security Door (Diamond Classic)

Diamond Grill Design Door

This diamond security door features a classic diamond lattice pattern formed with intersecting steel bars. The repeating diamond layout creates a simple, structured design that has been widely used in traditional security doors.

The pattern provides a balance between visibility and protection, allowing airflow and outward view while maintaining a strong steel barrier across the doorway.

This design is known as the (Diamond Classic) in our range. It’s fabricated from welded steel construction and produced to suit the exact dimensions of the doorway.

The diamond pattern can also be adjusted in spacing or proportion if a variation of the traditional design is required.

Professional installation is essential

Every doorway is slightly different, which is why accurate measuring and professional fitting are essential. We measure your doorway precisely before manufacturing so it is built for a perfect fit, ensuring the door frame, hinges and locks align correctly.

Incorrect installation can lead to gaps and misalignments, effecting the security and robustness of the product.

Our professional installation ensures the door operates smoothly and delivers the level of security it was designed to provide.
