What is red iron construction?

Red iron refers to structural steel I-beams, columns, and rafters — typically coated with a red oxide primer — used as the primary load-bearing frame of a building. It's the backbone of barndominiums, warehouses, and most commercial metal buildings.

Are your welders certified?

Yes. Our welders hold current certifications and perform all structural welds in accordance with the project's engineered connection details and applicable building codes.

Can you handle the full steel package on a project?

We manage everything from coordinating with the fabricator and detailer through on-site erection and welding. We can also pour the foundation and set anchor bolts, giving you a single point of contact for the entire structural scope.
