FAQ
Metal building questions
The things every buyer asks before they sign.
What's the difference between a pre-engineered building and a pole barn?+
A pre-engineered building is a red-iron/steel-framed structure engineered and stamped for your specific loads, with clear-span interiors and no interior posts. A pole barn is post-frame — wood columns set in the ground with steel roofing and siding. Pole barns are faster and cheaper; pre-engineered buildings span farther, carry more, and satisfy stricter commercial permitting.
How long does a pre-engineered building take?+
Plan on roughly 10 to 12 weeks from order to delivery. That sounds long until you remember what still has to happen on your end — clearing, grading, permits and slab. Most customers who start the building order early end up waiting on the site, not on us.
Do you provide engineered drawings?+
Yes. Pre-engineered packages come with stamped engineering for the applicable building code in your area and your local wind/exposure conditions.
Can I get a clear-span with no interior columns?+
Yes — clear spans are one of the main reasons to choose pre-engineered. We'll size the frame to the widest span your use actually needs.
Do you erect the building?+
We supply the complete building package and work with erectors and contractors around the country. Tell us where you're building and we'll point you to crews we trust.
Can I add insulation, doors and windows?+
Absolutely. Roll-up doors, sliding barn doors, bi-fold doors, entry doors, windows, lean-tos, gutters, wainscot, liner panel and several insulation systems are all quotable line items.
Not sure which one?
Pre-engineered or pole barn?
If you need wide-open commercial space, higher loads and stamped engineering, go pre-engineered. If you need cover for equipment, hay or a workshop — fast and economical — a pole barn is usually the better buy.
