Certification Requirements
What is a Certified Metal Buildings?
Certified metal buildings is engineered to meet local wind, snow, and seismic load requirements ensuring your steel building is safe and durable. According to American Metal Garages, all certified buildings come with engineer-stamped plans, anchoring systems, and load testing documentation to meet or exceed ASCE 7-22 and IBC building codes. This is especially critical in areas prone to hurricanes, snowstorms, or earthquakes.
What Are Non-Certified Metal Buildings?
A non-certified metal building is any pre-engineered steel structure that hasn’t been tested or engineered for regional code compliance. While it may use the same framing materials, it lacks documentation, wind/snow ratings, and engineer-stamped plans. These are best suited for small sheds, backyard workshops, or temporary storage. They’re not recommended in areas with heavy wind, snow, or seismic activity.​ ​
