Painting and Surface Preparation
{"Image DocumentName": "Painting and Surface Preparation", "Image ImageDescription": "Question 37: When must structural steel be painted? Answer: As stated in AISC Specification Section M3.1, shop paint is not required unless specified by the contract documents. Therefore, fabricated structural steel is left unpainted unless painting requirements are outlined in the contract documents. In building structures, steel need not be primed or painted if it will be enclosed by building finish, coated with a contact type fireproofing, or in contact with concrete. When enclosed, the steel is trapped in a controlled environment and the products required for corrosion are quickly exhausted. (Ref.
