Simpson Steel Building Company has been providing metal buildings to the great state of Texas 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 steel building kits have never been denied a permit in any of these instances or areas. Whether you are using our patented truss design to keep project costs down or need a larger rigid frame structure with ibeams, we’ve got a kit that will fit your project’s needs.
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 Texan 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 Steel is proud to be a trusted provider of metal building solutions across Texas, offering high-quality, pre-engineered structures tailored for residential, commercial, and agricultural use.

Discover the Benefits of Our Steel Building Kits
Our pre-engineered steel building kits are designed with both strength and affordability in mind. Using our patented steel truss frame design, our buildings offer the structural integrity of a rigid frame while reducing material costs by nearly 30%. This innovation makes our buildings ideal for everything from personal storage and garages to large-scale warehouses, agricultural shelters, and recreational centers.
Each kit is designed to meet local building codes and includes all necessary components for easy assembly. While we are not a custom design firm, we do offer minor structural modifications to accommodate unique site requirements. This flexibility ensures that our buildings suit a variety of applications without compromising strength or compliance.
Choose From a Wide Range of Applications
At Simpson Steel, we manufacture more than just standard metal building kits. Our portfolio includes aircraft hangars, mini storage buildings, processing plants, church facilities, and even recreational centers. While steel truss buildings are limited to 50 feet in width and 18 feet in height, they’re a perfect fit for non-extreme snow and wind load conditions.
For customers with more complex design needs, such as hangars or large industrial spaces, we also offer rigid frame structures. Our extensive experience allows us to support everyone—from individual homeowners to commercial and industrial clients—across Texas and beyond.

Over the years we’ve seen Barndominium homes that leverage a metal kit as the exterior become more and more popular in Texas. Simpson can provide complete engineered plans, engineered design calculations, and engineered foundation plans that are stamped by a licensed Texas engineer in the event you need these items for your residential build. In the event your project doesn’t require engineer stamped items and non-stamped drafted plans will suffice, we’ll remove those unneeded engineering costs and pass those savings on to you!
