The Fenestration and Glazing Industry Alliance (FGIA) has updated a specification covering requirements for corrosion resistant coatings on carbon steels used for hardware components in fenestration applications. AAMA 907-23 "Specification for Corrosion Resistant Coatings on Carbon Steel Components Used in Windows, Doors and Skylights," an FGIA document, is now available for purchase in the FGIA online store. This document was last updated in 2015.
About the document
The requirements in AAMA 907 are functional and are not intended to address aesthetics. Due to the diversity of corrosive environments that windows, doors and skylights are exposed to, this specification does not imply a specific service life. Fasteners, which are an integral part of the fenestration hardware, are included in the scope of this specification.
What FGIA says
“AAMA 907 is a critical hardware document that is referenced by most other codes and defines a pass/fail criteria for products tested to ASTM B 117,” says Chris Griffin Vice Chair of the document’s developing group, the FGIA Steel Component Corrosion Task Group. “This newest version is important because it adds back in established allowances for zinc dichromate plating, which had been removed from the previous version.”
“This specification is referenced in many of the 900 series hardware standards,” says Dan Raap, Chair of the developing group. “Many hardware components are zinc plated with chromates such as sliding patio door rollers.”
