We’re your #1 source for on-site and shop fabrication services.

From our field services and equipment fabrication, to our leadership and incredible employees, customers know they can depend on CUST-O-FAB. We take pride in our commitment to go above-and-beyond when serving our customers—we strive to make their jobs easier. Throughout the last four decades, we've built up the most experienced teams in the heat transfer and downstream construction industries.

The things that our customers depend on—safety, quality, schedule, and value—those are the pillars that make up our core values. From start to finish, we’re there for our customers through every step of a project.


Our field services are expertly coordinated with our fabrication locations. We have a dedicated On-Site Services division to provide our customers with comprehensive solutions for the issues that arise in the field. On-site repairs and modifications can be made to any of the heat transfer equipment that your site requires. When an emergency shutdown occurs, we’re available 24/7 with on-call crews that can get you back up and running as soon as possible. Our field crews know exactly how to get in, get things fixed safely, and leave your facility better than they found it.
