Catapult Steel Buildings will install on just about any level surface. Our buildings are supported by a base rail that runs the length of the building. This rail comes in a single run and is not adjustable. However, the leg height has a 4" adjustment that allows us to compensate for some slope or grade issues. For larger structures, it is recommended that you have your site graded to ensure the strongest structure possible.
***The information below is provided for illustrative purposes. Catapult Steel Buildings does NOT recommend preparing your surface until after the building is ordered and you receive an official copy of the drawings. Catapult Steel Buildings is not responsible for the accuracy of the below information.
