Innovative Manufacturing Technology

HSI is proud to have a long history of adaptability. As technology advances and new constraints come into play, we change the way we approach our work.

HSI has taken monumental steps forward in technology for welding, enabling streamlined service and prompt manufacturing timelines.

HSI Quality Project Management

Our organization gives you excellent control over your projects, with fabrication, refractory installation and painting operations combined at a single location. Because of our ability to manage all work operations, schedules can easily be compressed, which ultimately aids in eliminating delays that would otherwise result from the coordination of several sub-contractors.
