The applied primer must be tested and meet the passing criteria of ANSI A250.10-2011 Test Procedure and Acceptance Criteria for Prime Painted Steel Doors and Frames. Factory pre-treatment (surface preparation) prior to prime paint Steel must be thoroughly cleaned and treated (phosphatized [also known as bonderize]) and a rust inhibiting primer applied. After fabrication the door panels or frame members are washed and de-greased though an automatic washing system. Phosphatizing is one of steps in this pretreatment process. Phosphatizing Phosphatizing makes it possible for paint to give the maximum protection to metal. There are two basic functions of phosphatizing: 1. Phosphatizing etches the metal and thereby provides an effective anchor for the paint. Bare metal surfaces allow only the minimum of paint adhesion. Phosphatized metal surface have an affinity for paint and keeps the paint from lifting off or peeling. 2. The phosphate coating is non-metallic and acts to keep out any moisture which might break the paint film and reach the base metal. A scratch on untreated metal breaks through the paint and allows rust to work back from the scratch and lifts the paint off. Phosphatizing prevents the creep of rust and restricts the damage to the scratch itself. When phosphatized metal is combined with Steelcraft's top quality baked-on, rust-inhibiting, prime paint, the maximum protection against rust has been achieved. Steelcraft primers All Steelcraft Frames, Doors and Architectural Stick components shall be cleaned, phosphatized and finished standard with one coat of factory baked-on, rust-inhibited primer in accordance with ANSI A250.10-2011 Test Procedure and Acceptance Criteria for Prime Painted Steel Surfaces for Steel Doors and Frames. Omit prime paint is available for Steelcraft doors as cold rolled or galvannealed material. Frames must be primed from Blue Ash, OH, but can be omit prime paint from Chino, CA as galvanealled material only. Doors and frames without prime paint from the factory will limit the manufacturer's warranty. Primer paint testing The industry standard ANSI A250.10-2011 Test Procedure and Acceptance Criteria for Prime Painted Steel Doors and Frames is comprised of the following paint surface tests: • Salt spray testing in accordance with ASTM B117-09. • Condensation testing (humidity) in accordance with ASTM D4585-99. • Impact test in accordance with ASTM D2794-93 (2010)e1. • Film adhesion test in accordance with ASTM D3359-09e2. Primer test results Steelcraft factory applied baked-on primers conform to the industry standard ANSI A250.10-1998 with the following performance: Test Standard Hours Results Salt Spray ASTM B117-09 120 Passed Condensation ASTM D4585-99 480 Passed Impact Test Gardner Direct 20 in. lbs. with 1⁄2 " ball N.A.Passed Adhesion ASTM D3359-09e2 N.A.See Note 1 Notes: 1. 4B adhesion, which exceeds the test acceptance level of 3B. 2. Test procedure ANSI A250.10 is for factory primed steel doors and frames. To insure integrity of the prime painted coating, jobsite storage must be in accordance with sections 2 and 3 of this manual, ANSI/SDI A250.10 and HMMA 840. 3. Test procedure ANSI A250.10 is a performance standard for the factory prime applied to steel doors and frames. Film thickness of the primer is not mandated by this standard.General InformationFramesDoorsLights and LouversElevationsHurricaneSpecialtyHardwareFire Rated ProductsPerformanceArchitecturalVariationsVariationsTornadoHome DocuSign Envelope ID: 97A9508F-537F-4A89-96AD-A82F9ABD3708
