Simpson Steel Building Company has been providing metal buildings to the great state of Alabama 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 Alabamians 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.   

Steel buildings in Alabama must be designed to be strong enough to handle a very wide range of climates throughout the state.  Simpson’s steel building kits are prepared to handle the lighter wind loads in or around Huntsville, Decatur, Cullman, Anniston, Birmingham, Tuscaloosa, Auburn, and Montgomery, up to the heavier wind loads as you approach the coast in areas such as Mobile, Enterprise, and Dothan. Simpson can provide complete engineered plans, engineered design calculations, and engineered foundation plans that are stamped by a licensed Alabama engineer in the event you need these items for permitting. Our building kits have never been denied a permit in the state of Alabama   

You can use our 3D Design Tool to create and visualize the Alabama building needed for your upcoming project! Or call one of our building experts at (800) 255-7624 to help you create a metal building to meet your specific needs.
