CNC Punching and Folding

Fabricated sheet metal panels and components

We produce all fabricated parts in-house using our state-of-the-art manufacturing facilities which include CNC punching and break press folding machines. Flat sheet aluminum and steel can be punched with any number of holes or series of slots to produce special front panels, covers, tops and base panels for our enclosures. Fully bespoke enclosures and sheet metal parts can also be fabricated to your design using these processes. We work to your drawings and specifications.

See below for a full stock list of sheet metal materials and standard hole punches we have available:

Options available:
