Red iron buildings.Quoted for your project.
When your project calls for a red iron building system, Beverly Industrial can help you request a quote and understand how it compares with cold-formed steel.
What is a red iron building?
"Red iron" is the industry's nickname for structural steel framing — named for the red-oxide primer often applied to the main frames.
In a typical red iron building, heavy primary frames — columns and rafters made from hot-rolled steel shapes or welded steel plate — form the building's main skeleton. Lighter secondary members, often cold-formed purlins and girts, span between those frames to support the roof and wall panels.
Red iron systems are commonly used where a building's design calls for heavier primary framing, such as larger open interiors. Like any steel building, the framing is designed around the building's dimensions, use, location, and loads.
Red iron and cold-formed steel, compared.
Neither system is always better. Here's how they generally differ:
| Cold-formed steel | Red iron (structural steel) | |
|---|---|---|
| How it's made | Shaped from steel sheet or coil at room temperature | Primary frames made from hot-rolled shapes or welded plate |
| Typical members | C- and Z-sections, track, and built-up members | Heavier columns and rafters, often with cold-formed secondary members |
| Member weight | Lighter, easier to handle individually | Heavier primary members that typically need lifting equipment |
| Connections | Commonly screwed or bolted | Commonly bolted primary connections |
| Corrosion protection | Typically a metallic coating (e.g., galvanized) applied before forming | Typically a primer or paint system; varies by project |
| Best fit | Depends on use, size, location, loads, and scope | Depends on use, size, location, loads, and scope |
General comparison for education only. The right system for your building depends on its specific requirements and design.
The right answer depends on your project.
Building use, dimensions, clear-span needs, openings, location, loads, budget, and schedule all play a role. Tell us what you're planning, and we'll help you understand whether cold-formed steel, red iron, or both are worth quoting.
