Red Iron Buildings
Structural steel framing for heavy-duty, long-span buildings.
Red iron is the framing people ask for when a building has to carry more, span farther, or stand up to serious daily use.
What it is
"Red iron" refers to structural steel members finished with a red oxide primer. It's the heavy framing used in many larger metal buildings — I-beam columns and rafters that form the primary structure before the exterior goes on.
Who it's for
- Large-span shops and equipment buildings
- Commercial and industrial structures
- Buildings with overhead lifting or hanging loads
- Owners planning a long-service-life building
Common applications
- Heavy equipment shops
- Commercial service buildings
- Large clear-span storage
- Shop buildings with tall eave heights
Customization options
- Span width and eave height
- Frame configuration for the loads you describe
- Large door openings and framed openings
- Wall and roof panel selections
- Interior finish level for working space
Why choose this build
If the building needs to be wide open inside, tall, or carry more than a conventional structure, structural steel framing is worth discussing early — it shapes everything else about the project.
