Commercial Structural Steel Fabrication
From steel framing to mezzanines, we build the foundation of your project.
When steel has to carry weight, the fabrication has to be right the first time. There is no fixing a beam that shows up a half inch short once your crew is already on site.
San Marino Iron Inc. fabricates custom structural steel for commercial properties across Southeast Michigan. We can shape steel into nearly any form to meet your design and engineering requirements, from load bearing framing to the ornamental work people actually notice.

Our Structural Steel Services
Every commercial and residential project has unique structural requirements, which is why we fabricate each project to meet your specific needs. Our structural steel services include:
- Beams, columns, and posts
- Angles, channels, and plates cut to spec
- Lintels and headers for masonry openings
- Stair stringers, landings, and mezzanine framing
- Steel decks, canopy frames, and handicap ramps
- Garages, pool cabanas, and steel enclosures
Steel comes in different grades, and we spec the grade to the load the piece actually has to carry. Shapes can be hot or cold rolled, or built up by welding flat or bent plates together when a stock shape will not do the job.
