Metal Fabrication At our premises in Welwyn Garden City we have a fully functional metal fabrication shop. We have in our employ two full time metal working staff who between them have over 50 years of experience. This gives us the ability to manufacture special one off enclosures together with bracketry and specialist metalwork for all applications, enabling us to maintain a high standard of product. Also all copper busbar work is done in house and to this effect we have cutters, benders and a multi-station turret press for the shaping and punching of holes in all varieties of metal.
