Custom Steel Structures by Steel Structures America
Metal buildings in Washington state have never been more in demand, and for good reason. Whether you are a contractor who needs a purpose-built shop in Spokane Valley, a farmer looking to shelter serious equipment in the Yakima Valley, a business owner expanding a commercial operation in Eastern Washington, or a property owner planning a barndominium on rural acreage, a steel building delivers the combination of durability, speed, and clear-span usable space that traditional construction cannot match. Steel Structures America has been designing and building custom metal buildings across Washington since 1995, and our two Washington sales offices put us right in the markets we serve.
With more than 15,000 completed buildings across Washington, Idaho, Oregon, Montana, Colorado, and Wyoming, SSA is the region’s most experienced metal building contractor. We are not a national kit company or an out-of-state online retailer. We are a locally operated business with Washington-based sales offices, regional crews, and three decades of completed projects across Eastern Washington.
Why Post Frame
Why Washington Property Owners Choose Metal Buildings
Washington’s geography, climate, and land use patterns make steel buildings a strong fit for a wide range of project types. Eastern Washington in particular presents conditions that reward properly engineered metal construction, from the snow loads of the Selkirk and Blue Mountain foothills to the wind exposure of the Columbia Basin and the Yakima Valley floor.
Here is what draws Washington property owners and businesses toward metal building construction:
Built for Washington Weather
Eastern Washington winters bring real snow loads and cold that require properly engineered structures. Spokane County sits in a snow load zone that demands careful structural calculation to avoid risk.
Fully Custom
Every SSA metal building is designed from scratch. Size, layout, siding, roofing, overhead doors, insulation, lofts, lean-tos, and more are all specified to fit your property and your goals.
Efficient Build Process
Pre-engineered components and in-house manufacturing streamline construction and reduce delays compared to traditional home builds.
Better Long-term Value
Lower maintenance, durable materials, and efficient construction make post-frame a smarter long-term investment than stick built.
Low Maintenance
No painting, no rot, no termites. Steel structures require virtually zero maintenance year after year.
Purpose Flexibility
Every SSA building is designed from scratch. Size, layout, siding, roofing, overhead doors, insulation, lofts, lean-tos, and more are all specified to fit your property and your goals.

Hear from real customers who chose Steel Structures America for their metal building design and construction.
“Had a great experience with Craig O’Neal. He’s really great at showing how the structure will look, I was impressed with how quickly he can make modifications to the structure on his laptop so we have an excellent idea of what the final product will look like. Craig is knowledgeable and straightforward about the costs and the timeline. Total Pro!”

Metal Buildings in Spokane and Spokane Valley
SSA operates a full sales office in Spokane Valley at 13520 E. Nora Ave., which puts our team directly in the center of the Inland Northwest’s most active construction market. Spokane and Spokane Valley have seen consistent population and commercial growth, and demand for metal buildings across Spokane County and surrounding counties has tracked that growth closely. Our Spokane Valley team works with buyers throughout Spokane, Liberty Lake, Greenacres, Cheney, Airway Heights, and across the broader Spokane metro area.
Spokane’s climate creates specific structural engineering requirements that SSA understands firsthand. The city and county sit in a genuine snow load zone. Ground snow accumulation is a real structural consideration for buildings in this region, and the engineering demands differ meaningfully between a building on the exposed West Plains near Airway Heights and one in the more sheltered floor of the Spokane Valley. Wind loads on the West Plains and the Columbia Basin require independent engineering calculations from snow-heavy mountain terrain to the north. SSA engineers every Spokane-area metal building to meet the specific structural demands of its site, using Washington-licensed engineering professionals.
The Spokane Valley office also serves buyers in the broader Inland Northwest, including Stevens County, Lincoln County, Adams County, and rural communities across northeastern Washington. Buyers building on property anywhere within a reasonable drive of Spokane have access to a local SSA team rather than coordinating with a contractor based hours away.
Spokane and Surrounding Area
Snow loads vary by elevation and site. SSA uses Washington-licensed engineers and the Ground Snow Loads for Spokane reference to correctly calculate structural requirements for every Washington build.
Yakima Valley & the Rest of Eastern Washington
Our Yakima office serves serves buyers throughout Yakima County, Kittitas County, and the surrounding region. We have extensive experience with the specific code and climate requirements of these areas.

Metal Buildings in Yakima and Central Washington
SSA’s second Washington sales office is located in Zillah at 804 Zillah West Drive, placing our team directly in the Yakima Valley to serve buyers throughout Yakima County, Kittitas County, Benton County, and the surrounding region. The Yakima Valley is one of the most agriculturally and commercially productive areas in the Pacific Northwest, and demand for metal buildings in Yakima and across central Washington reflects that productivity.
The Yakima Valley presents different engineering challenges from the Spokane region. Snow loads in the valley floor are generally lower than in Spokane County, but wind loads can be significant in exposed locations, and the valley’s agricultural operations place demanding structural requirements on storage and equipment buildings. SSA engineers every Yakima Valley metal building to the specific structural requirements of its site, not to a generic regional estimate that may not reflect actual site conditions.
The Zillah office serves buyers throughout the Yakima Valley, including Yakima, Selah, Union Gap, Wapato, Sunnyside, Grandview, Prosser, and communities across Yakima County, as well as buyers in Benton County and the Tri-Cities area to the east. The Zillah team also works with agricultural operations throughout the valley who need large equipment storage buildings, hop kiln facilities, packing shed structures, and agricultural maintenance shops.
Building Options
Customize Your Washington Metal Building
One of the advantages of working with SSA is the depth of customization available. Your metal building isn’t a catalog item, it’s a custom structure designed around your land, your use case, and your budget. Here is a look at what you can specify.
Metal Siding and Roofing
SSA owns Metal America and offers more than 50 colors and specialty finishes for metal siding and roofing. This includes standard painted steel in colors from ash gray to charcoal, as well as specialty printed finishes including barnwood, brick, and other decorative options. Two-tone combinations with wainscot accents are popular in Washington and give buildings a finished, polished look.
Overhead Doors
Your overhead door configuration matters as much as your building dimensions. SSA owns Garage Door Design to supply Therma Tech insulated steel doors and other options in sizes from standard residential widths up to doors large enough for combines and big rig trucks. Matching painted finishes keep your building looking clean and intentional.
Perma-Column Foundations
SSA is a Perma-Column partner, offering precast concrete column foundations as an alternative to traditional buried wood posts. Perma-Column eliminates wood-to-soil contact, which is the primary cause of post rot and structural failure in post-frame buildings over time. If you want a building that holds up for generations without foundation concerns, Perma-Column is worth a conversation.
Lean-Tos and Additions
Many Washington metal buildings include lean-tos on one or both sides for additional covered storage, a sheltered equipment staging area, or a covered porch on a barndominium. SSA designs and builds lean-to additions as part of the original structure or as additions to existing buildings.
Lofts and Interior Finishing
For shop and barndominium projects, SSA can include loft floors, interior wall systems, insulation, and finished interior spaces. If you want a shop with a finished office or apartment above, or a barndominium with a modern interior finish package, we design that into the building from the start.
Insulation Systems
For shops, garages, and living spaces in Washington’s climate, proper insulation is critical. SSA offers spray foam, fiberglass, and rigid board options appropriate for your building’s use.
