Custom Steel Fabrication Facilities

Between our main facility in Tulsa, Oklahoma, and our nearby Port facility, we are able to build and ship fully assembled vessels using our Maximum Shop Assembly (MSA) process. With this combination of capable facilities and our years of custom-steel manufacturing experience, we can fabricate vessels of any size.

Reliable Transportation for Your Custom Steel Fabrications

When using our MSA process to deliver fully assembled vessels, we have achieved considerable project savings by cutting the need for man-hours in the field, alleviating overcrowded job sites and making delivery schedules more reliable.

If delivering fully assembled vessels isn’t practical for a project or job site, we can create a transportation and delivery method that is more suitable to the project’s parameters.
