Materials Steel Sheet metal work is often associated with the use of a widely used metal, steel. We use new technologies and traditional skills to work in a multitude of ways to manipulate this material. Stainless Steel The description ‘stainless steel’ refers to a number of alloys which are all resistant to corrosion. In other words, they won’t rust or stain. Brass Brass is an alloy consisting mainly of copper and zinc. The amount of each of these will vary depending upon the type of brass being produced. Aluminium Although it was only isolated as relatively recently as 1825, aluminium is actually the third most abundant metal in the earth’s crust. Titanium Titanium is used widely, although sparingly, due to its rarity and therefore cost. We have used Titanium for Automotive components.
