HSI has long been the “go-to” provider for custom steel fabrication. HSI performs all disciplines of work in house with HSI staff. This includes engineering, detail design drawings, steel fabrication, coil fabrication, and refractory and coatings. The core group of our managers and craftsmen have worked together for over 20 years. They deliver top quality equipment on schedule for the most demanding projects that engineering companies and end users can develop. HSI’s managers and craftsmen stand ready to deliver your project with the same focus.

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 facilities, paired with our years of manufacturing experience, we can fabricate vessels of any size.

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 jobsite, we can create a transportation and delivery method that is more suitable to the parameters of the project.
