Our Service

We supply Full Sheets, Part Sheets, Cut to Size and CNC shape cutting, we can take DXF and the most common file types. We normally TIG weld Copper, Brass, Bronze, Stainless, and Aluminium. MIG weld Corten and Mild Steel. Solder Zinc and Pewter. It is posible to TIG weld zinc but the fumes are quite toxic so care must be exercised.

We can offer Prototyping, One offs and short runs in Non Ferrous on our CNC flat bed router, sheet size up to 3000mm x 1500mm. Sheet metal thickness up to 6mm or from our Sheet Metal Gauge Chart 4 SWG or 1/4″.

We also manufacture in copper brass and zinc, table tops, bar tops and features, see more in our gallery.

More recently we have expanded our metal spinning department with the addition of another spinning lathe. We use these to make round copper brass and zinc table tops.
