Simpson Steel Building Company has been providing metal buildings to the great state of Missouri 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 any Missourian 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 Missouri engineer in the event you need these items for permitting. Most projects in Missouri 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!
