About us

One workshop. Two speeds.

We measure in millimetres and deliver in tonnes. One beam holding up a new open-plan kitchen, or a frame holding up an entire distribution hub — both are drawn in the same 3D model, cut on the same machines and checked by the same eyes before they leave our yard in Essex.

Small enough to answer the phone. Big enough to carry the load.
