Send a drawingDDC · Design Deliver Construct
DDC is a subcontract drawing office for steel fabricators across the UK, run by Darren Clark. We model every job in 3D and produce the drawings, lists and machine files your workshop needs. Darren came up through fabrication and installation, so every drawing is made with the cutting, welding, lifting and bolting in mind.
See our workOur Services
From the first GA to the last NC file, we cover the whole drawing package for structural steelwork and architectural metalwork.
