There is a lot happening inside ProMart’s shop right now.

We have major projects lined up into 2028. We are investing nearly $2 million into robotic welding, advanced laser cutting and profile processing, automated material handling, new CNC technology, and facility improvements.

This is an opportunity to take real ownership of a growing fabrication operation and help shape what ProMart becomes.
