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.

Frequently Asked Questions

Why is structural steel a better choice than wood for buildings in Michigan?

Structural steel performs better than wood in Michigan's climate because it can handle heavy snow loads and high winds more effectively. Steel has a high strength-to-weight ratio, which allows buildings to support large loads without requiring excessive structural elements. Unlike wood, steel is immune to rot, pests, and moisture-related damage, which is beneficial during humid summers. It also provides a less suitable surface environment for mold growth, helping maintain healthier indoor air quality.

How does structural steel improve construction timelines?

Structural steel can significantly accelerate project timelines because many components are fabricated off-site before arriving at the construction site. Prefabrication reduces on-site labor, minimizes material waste, and allows crews to assemble the structure quickly. Steel components can often be erected immediately once delivered, eliminating many delays associated with curing or on-site material preparation. In many projects, structural steel can reduce construction time by up to 30% compared to wood.

Is structural steel a sustainable construction material?

Structural steel is considered one of the most sustainable building materials used in modern construction. More than 80% of structural steel members are produced using recycled metals, and steel itself is 100% recyclable at the end of a building's life cycle. This circular lifecycle helps reduce waste and the demand for new raw materials. Steel also supports energy-efficient building designs that can help projects meet modern energy standards, such as the 2021 International Energy Conservation Code adopted in Michigan.

Can using structural steel reduce long-term costs for developers?

Yes, using structural steel can lead to significant cost savings over the life of a building. Its durability and resistance to pests, rot, and moisture reduce maintenance and repair costs compared to wood structures. In some cases, switching from wood to steel construction can also lower insurance premiums, with some developers in Michigan saving more than $100,000. Additionally, using standardized steel members instead of unique components can further reduce material and fabrication costs.

What role does steel fabrication and erection play in commercial construction?

Fabrication shapes structural steel into I-beams, U-channels, angles, and tees, cut and drilled to your drawings in the shop. Erection is the field half, where crews set those pieces and connect them by bolting or welding. Done right, the frame comes out square and the trades behind you stay on schedule.

Do you install the fences and gates you build?

Yes. We handle the entire job in house, from measuring and fabricating to setting posts and hanging gates. Modular kits exist, but a custom iron fence has to follow the grade of your property and needs proper concrete footings to stay straight through Michigan winters, which is why we fabricate and install ours ourselves.

Do you repair existing iron fences and gates?

We do. Rusted pickets, sagging gates, broken hinges, shifted posts, and sections damaged by a vehicle are all repairable. If the original ironwork is worth saving we match it. If it is not, we fabricate a replacement that ties cleanly into what is already there.
