How Much Does a 30′ × 40′ Steel Building Cost?

While many companies will throw out a number without asking questions, we don’t play that game. Your price depends on your location, snow and wind load requirements, selected features, and your build site. We quote based on what’s **real**, not what just sounds cheap.

  • Snow & wind loads
  • Doors & window options
  • Insulation & interior finishes
  • Roof style & panel gauge
  • Local building code compliance
  • Delivery & site location

Most 30×40 steel buildings start between $12,000–$22,000+ for the base kit — but your final price depends on what you actually need, not some cookie-cutter estimate.
