AISC Certification sets a standard for the steel industry. Companies that are AISC Certified have been through a rigorous initial evaluation, and are subject to yearly reviews. An independent auditing company confirms that companies have the personnel, knowledge, organization, equipment, experience, capability, procedures, and commitment to produce the required quality of work for a given category, such as our fabricating plant.
