Sheet metal folding

What is sheet metal folding?

Metal folding is the process that gives the metal product its shape. A machine is used to bend or fold the metal in order for it to reach the intended form for your needs.

What we do

Our folding department consists of manual and automated press brake machinery and folders meaning we are able to meet customer requirements. Our commitment to improving our customer service means that we are continually reinvesting into the company to give the best folding solutions to our customers.
