At Simpson Steel Building Company, we proudly serve Oklahoma with high-quality steel building kits designed to meet a wide range of structural needs. Whether you’re planning a metal building for a garage, workshop, or agricultural use, our patented steel truss system offers the strength of rigid frames at a fraction of the cost. With over 40 years of experience, we’ve refined our process to deliver pre-engineered kits that are easy to assemble, code-compliant, and built to last.
Strength, Simplicity, and Savings
Our product line includes everything from mini storage buildings and airplane hangars to commercial warehouses and residential barndominiums. Each steel building kit is manufactured using 12-gauge red iron structural steel and 26-gauge metal sheeting for enhanced durability. The truss design mimics the shape of traditional wooden trusses but leverages steel’s superior strength and longevity. We offer minor layout modifications to accommodate doors, windows, and other functional elements, ensuring your metal building serves its purpose efficiently.
Designed for Oklahoma
We’re not a design firm, but we are experts in steel building manufacturing. Our kits are pre-engineered and shipped nationwide, including flexible freight options for Oklahoma customers. We provide detailed assembly instructions and can refer local contractors if you prefer professional installation. Our team is committed to delivering value, reliability, and responsive support throughout your building journey. If you’re ready to invest in a metal building that combines affordability, strength, and simplicity, Simpson Steel Building Company is here to help. Contact us today to get started with a custom quote or explore our 3D design tool to visualize your next project.
Simpson Steel Building Company has been providing metal buildings to the great state of Oklahoma 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!
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 anyone in Oklahoma 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 Oklahoma engineer in the event you need these items for permitting. Most projects in Oklahoma 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!

Frequently Asked Questions
How does your steel truss system compare to traditional rigid frames?
Our truss system achieves structural integrity through design rather than material thickness. This results in lower steel usage, reduced shipping weight, and easier assembly. It’s a cost-effective alternative without sacrificing strength.
Are your metal buildings suitable for Oklahoma’s weather conditions?
Yes, our buildings are engineered for moderate snow and wind loads, which align with most regions in Oklahoma. For areas with more extreme conditions, we can advise on structural adjustments or alternative solutions.
Can I install the building myself or do I need a contractor?
Many customers choose to install the kits themselves using basic equipment like a forklift or tractor. However, we also maintain a list of trusted Oklahoma contractors for those who prefer professional assembly. Either way, we support you throughout the process.
