Building Smarter With Our Patented Steel Truss Design
At the core of every Simpson Steel building is our patented steel truss frame, a design innovation that provides the same strength and stability as rigid frame buildings but at a lower cost. Unlike traditional rigid frames that rely on heavy I-beams, our truss system gains its strength through intelligent engineering.
This approach makes our steel buildings in Wisconsin not only durable but also affordable — typically costing around 30% less than comparable rigid frame structures. With widths up to 50 feet and heights up to 18 feet, our truss design offers a clear-span interior ideal for open storage, machinery, or workspace.
Whether you’re building a new agricultural facility or adding storage space for your growing business, our pre-engineered kits are a smart investment for long-term performance.
Delivering Reliable Service and Easy Construction
At Simpson Steel Building Company, we’re dedicated to making the building process as straightforward as possible. Our experienced team provides complete support from your initial inquiry through to delivery, ensuring you have everything you need to assemble your building efficiently.
Each pre-engineered metal building kit in Wisconsin comes with high-quality components, detailed instructions, and customer service that’s always just a phone call away. We take pride in offering flexible options that make sense for our customers — providing both strength and value without unnecessary complexity.

Simpson Steel Building Company has been providing metal buildings to the great state of Wisconsin for over 40 years. We’ve become very familiar with and kept up with local building code changes that have come up over the years. Our patented truss design gives you all the benefits of a traditional red-iron structure for a much lower price point! If you are in the higher snow load areas of Wisconsin we offer a Rigid Frame building design that will meet any snow load requirement necessary while also still providing all of the functionality that you need.
Our bolt-together building kits are easy to assemble and only require a forklift or tractor with tongs to move around. This makes our building kit the perfect solution for any Wisconsin residents looking for an affordable DIY Kit for their project needs. Speaking of projects, our buildings work great for a multitude of uses, such as hay barns, stables, garages, shops, commercial buildings, and barndominium homes! In the event that you want someone to erect the building for you, we have a list of local contractors we can refer to help with that aspect of the project.
Simpson can provide complete engineered plans, engineered design calculations, and engineered foundation plans that are stamped by a licensed Wisconsin engineer in the event you need these items for permitting. Most projects in Wisconsin don’t even require engineer stamped items, and in these instances where non-stamped drafted plans will suffice, we’ll remove those unneeded engineering costs and pass those savings on to you!
