Some states and cities require building certification. Coast to Coast supplies certified metal barns to better serve everyone everywhere. A certified barn has extra corner braces, snow braces, anchoring, and sometimes stronger steel or more legs/bows, allowing for certification for up to 90lbs per sq ft of snow and 90 mph winds. These building are stronger and last longer than the less expensive non-certified buildings. Both, certified and non-certified buildings are offered in all areas, so it is the customer's responsibility to determine if they need a certified building or not. We always recommend certified buildings over non-certified. Contact our sales team about the certified steel barn for sale that interests you.
