When a metal building is labeled as “certified”, it means that a structural engineer has thoroughly evaluated the design or configuration to ensure it meets the necessary wind and snow load requirements. This certification is often a requirement when applying for building permits in certain areas, and provides assurance that the building is structurally sound and safe for occupancy.
Whereas a “non-certified” structure does not meet the necessary wind or snow load requirement, making it less structurally secure compared to a certified building.
