425 Fab Division is on point. No job is too big. They can fab up all your needs. They are family owned and employee driven and give back to their community. I know this from experience as I own a manufacturing business and they have exceeded all my requirements. Thank you 425 Fab

425’s Fab division is absolutely amazing. As a local fire chief, I found myself in a situtation that required immediate attention. A new fire truck with a bad weld in the pump plumbing. After contacting the seller they agreed to let 425 handle the warranty repair work rather then sending the truck out of state to the manufacture and waiting for up to two weeks to get the repair done. The quality of work was second to none and the customer service was even better. 425 is an awesome group of people working together to provide quality manufacturing and fabrication solutions to their customer’s needs.
