Suppliers of Atlantic’s master coils are hand-picked from the industry’s best producers. The steel coil we buy must meet stringent ASTM quality standard specifications for structural tubing, and satisfy dimensional specs for exhaust tubing. After purchase, coils are sent to slitters, then stored with them until immediately prior to production. When required for production, coils are released for shipment into AT&S. Upon arrival at our facility, coil edges undergo critical visual inspections to verify quality.
