Why Choose DIW?

Experience, quality and technical expertise

At DIW Ltd, we combine practical industry knowledge, precision fabrication and responsive customer service to deliver aluminium glazing solutions for modern construction projects.

Precision Fabrication

CNC machining for consistent quality

We understand the technical, commercial and regulatory requirements involved in construction, and we work closely with clients to keep projects moving smoothly.

Our CNC machinery centre allows for exceptional precision, ensuring consistent quality on every frame we produce.

Quality

Robust QA/QC and pre-delivery testing

Quality is central to the way DIW Ltd works and we operate a robust QA/QC system that sets us apart. Quality is built into every stage of our fabrication process, with each frame being checked before delivery using our in-house testing equipment.

This gives clients added confidence that products leave our Newark facility checked, verified and ready for the demands of site.
