Butler Building
Spec & Component Guide
Inside The Spec & Component Guide
Change orders on site usually trace back to a spec that wasn’t confirmed before fabrication. This guide walks through exactly what to check on your building’s structural steel, panel systems, and fasteners against your engineering drawings before construction starts. Built from AM Star’s own fabrication checklist as an authorized Butler distributor, it’s the same reference used internally to verify components before they leave the shop.
What's inside the guide
Structural steel sizing and tolerance ranges
Secondary framing specs
Roof and wall panel gauge and profile options
Fastener spacing and compatibility by panel type
Trim and flashing specs by building type
How to cross-check a delivered component against your engineering drawings

Who is this guide for
Built for builders and contractors scoping or bidding a Butler building project, and for crews confirming a delivery matches the engineering specs before installation starts.

What makes a Butler building different from other metal buildings?
Butler has been engineering steel buildings for over 125 years, and AM Star is an authorized Butler distributor, not a reseller of generic components. Every building you get through us uses genuine Butler engineered parts, backed by Butler’s manufacturing standards.
Can I customize the size and layout of my building?
Yes. Butler buildings are engineered to your exact specifications, size, use, and site requirements, whether that’s a small workshop or a large industrial facility. Our team works with you from initial design through structural engineering to make sure it fits your project.
How much does a Butler building cost?
Pricing depends on size, building type, durability grade, and site conditions, so there’s no single number that fits every project. Request a quote and we’ll get you accurate pricing fast, tailored to your specific building.
How long does the process take, from quote to finished building?
Timelines vary by project scope and current fabrication schedules. Once you request a quote, we’ll give you a realistic timeframe based on your specific building and location.
Do you handle engineering and permitting?
Yes. Every Butler building is engineered to meet local codes and structural requirements, with stamped drawings provided for permitting, backed by Butler’s manufacturing standards.

What's the difference between a Butler building and a barndominium?
A barndominium is one type of building you can build using Butler’s steel building system, combining residential living space with a metal building structure. It uses the same engineered components and durability standards as our other building types.
What if I'm not building new, I just need parts or repairs?
We also supply genuine Butler parts and components for repairs, replacements, or expansions, no need to order a full building. Browse our parts catalog or contact us directly.
