Fraying surfaces of splices and connections of all new structural steel elements will require abrasive blast-cleaning to Near White (SSPC-SP 10).
New steel will then be coated with NEPCOAT List A coatings including an inorganic zinc-rich primer, epoxy intermediate and aliphatic polyurethane topcoat. The owner-approved manufacturers include Carboline and International Paint.
