Recently we have invested heavily in fire rated ductwork, providing training and equipment to allow us to fully manufacture FIREMAC™ wrapped duct at a highly competitive price.

Design And 3D Modelling

Design & 3D Modelling

Calmec has invested heavily in design software allowing to remain on the leading edge of design and able to seamlessly take a project or concept through the design phase and on to full scale manufacturing. With the ability to fully model designs to scale and work through the initial problems often encountered with prototyping at the design stage instead of wasting materials and assembly hours manufacturing multiple prototypes.

Our design team are always looking for new software and manufacturing processes to keep costs down while ensuring quality is not compromised, Keeping UK manufacturing as a viable and effective option.

Strong communication and transparency are at the forefront of our design department and our team will fully dedicate our time and experience, giving you the confidence to bring products to life and leave crucial projects in our capable hands.

We have the facilities to provide product modelling, rendering, technical drawings, component procurement along with a host of other design capabilities. No project is too big or too small.


With an experienced and efficient team assigned to our assembly department, we can organise production lines with the capabilities to manage projects of any size that require electrical or mechanical assemblies. Working alongside the design department to pro-actively foresee issues that may be encountered in manufacturing so we can make the changes to the design early in the project.

Our team are always interested in the latest technology and we invest heavily in training and manufacturing methods to give us the ability to monitor productivity and ensure we are always working in the most efficient and effective manner.
