Steel Structures America

Steel Structures America builds custom post-frame steel buildings from 6 locations, including its Zillah, Washington office, with headquarters in Post Falls, Idaho and further offices in Sagle, Idaho, Spokane Valley, Washington, Bend, Oregon, and Longmont, Colorado. The company cites more than 30 years of experience and more than 15,000 completed projects, and describes itself as the Northwest's largest and most experienced post-frame steel building contractor. The catalog spans custom garages and shops, barndominiums and finished living spaces, barns and agricultural buildings, commercial and industrial buildings, and mini storage.

Projects are handled from design through construction, with engineering and permitting services folded into the process and warranty support after completion. Customization options are extensive: colors, roof styles, lean-tos, siding and roofing upgrades, insulation, framing choices, loft floors, garage doors, and aluminum pergolas. Financing options are available.

The website does not draw a hard line between shell and turnkey scopes, though it references finished living spaces for barndominium projects, so buyers should confirm how far finish-out extends on a residential build. For central Washington buyers, the Zillah office puts a large regional post-frame operation within local reach, with design, engineering, and permitting handled by the same company that erects the building.
