Talk to Cavity Trays about our non-standard preformed trays design and manufacturing service.

Custom Cavity Trays

Non-standard preformed trays, made in any shape or form.

At Cavity Trays, much of our work involves the design and manufacture of non-standard and special requirements. These are necessary in areas of the building where complicated junctions are encountered, and a preformed tray must be designed.

Our design team are experienced in dealing with the most challenging requirements. Send us your drawings, and we’ll advise you as part of our free service.

How does the process work?

From initial enquiry through to manufacturing, we’re on hand to guide you through the process from start to finish.

Design and Scheduling

Upon receipt of your enquiry, our technical specialists will identify, design and prepare a quotation which will be returned to you by our team. A confirmation template detailing your requirements is provided which can then be approved or amended.


When you are satisfied with our proposals, confirm the designs and wish to proceed, your products are designed in our CAD software. We will then schedule your bespoke requirements into our production programme.


Our engineers cut out precisely dimensioned trays on the latest leading-edge CAD/CAM digital cutting machines. Bespoke trays are stitched together using ultrasonic spot-welding equipment, plastic weld sealed before rigorous testing confirms watertightness.
