| Updated requirements for coatings on steel hardware components  The American Architectural Manufacturers Association (AAMA) has updated and released a document specifying requirements for corrosion resistant coatings on carbon steels used for hardware components in window, door and skylight applications. The document previously was updated in 2012. According to Jeff Dorsch (AmesburyTruth), chair of the AAMA 907 Update Task Group, "Voluntary Specification for Corrosion Resistant Coatings on Carbon Steel Components Used in Windows Doors and Skylights" recently was updated with a new test report section, and a clarified scope."The AAMA 907 standard for acceptable coatings for mild steel components and assemblies was re-worked to become more performance based and less prescriptive," says Dorsch. "In addition, specific references to cadmium plating were removed due to the material's inclusion on many of the green industry's red lists. A manufacturer can utilize any number of plating or material options as long as the results after neutral salt spray testing are in accordance with the 907-15 standard." The requirements in AAMA 907-15 are functional and are not intended to address aesthetics. Due to the diversity of corrosive environments that windows and doors are exposed to, this specification does not imply a specific service life. Fasteners are not included in the scope of this specification. write your comments about the article :: © 2015 Construction News :: home page |
