A family-run engineering company in Penybryn, near Hengoed, since 1977. We machine, fabricate and make tooling for industry, and we conserve steam engines, waterwheels and colliery machinery for museums, councils and private owners.
Both divisions share a well-equipped fabrication shop, so we can take a project from the first idea through to packing, delivery and maintenance, by phone, email or a meeting at your premises or ours.
Intricate and complex components for the medical, automotive and aerospace industries, designed in DelCam PowerShape, PowerMill and PartMaker. We make tools from your design, or alter and repair existing ones.
Steam engines, waterwheels and other large industrial objects, restored and maintained with the right materials and methods by a long-serving, apprentice-trained team.
Heavy and light fabrication in mild steel, stainless steel and aluminium, on or off site. We have made and erected portal steel buildings, hoppers, conveyors, machine guards and bespoke equipment, with folding, rolling, cutting, welding, shot blasting and painting all under one roof.
A selection of our conservation contracts, from colliery machinery for the national museum to a Scheduled Ancient Monument in Cardiff.
