MCA is part of a Zinc Coalition that was formed by IZA in the aftermath of the Washington Department of Ecology rainwater runoff project that was concluded in 2014. Misuse of the information related to zinc from the runoff report is influencing the Governor’s office and the legislative bodies.
Letter-writing advocacy, with guidance from IZA, is showing positive impacts. Several meetings have been scheduled with IZA and Coalition members to discuss the shortcomings in the runoff report and the outdated clean water regulations. MCA members that have facilities in Washington were asked to get involved in the effort. Similar issues are being seen in California, the Great Lakes region and in Canada.
The investigation of roof damage from high-wind events has shown that failure often initiates at the corners and/or edges of metal roofing. To address this situation, MCA has embarked on developing a test method standard that could be used to test the pullout strength of variations to edge perimeter details. A task group has developed a draft of the test method, which has been reviewed by several testing laboratories.
The next steps will be to test edge metal at different laboratories to determine if the test method is sound and repeatable among the laboratories. After testing and validation has been completed, the task group will create an industry guide and bring it to market. MCA will then pursue the ANSI standard process to create an industry standard. This is similar to the track that SPRI took for the development of their ANSI/SPRI ES-1 Standard.
MCA is conducting research at the University of Florida to evaluate the performance of discontinuous metal panels, such as modular metal panels and snap-together standing seam. From that evaluation we will be investigating how to characterize the air permeability of these types of roof panels in order to develop a new test method to more realistically reflect the wind uplift that these systems can withstand. The main test to be utilized for the work is the UL 1897 in static and dynamic mode. Wind tunnel testing and variations to existing industry test methods will be used. An industry Advisory Panel has been created and a literature search has been summarized. Recently the Experimental Research Plan was shared with the Advisory Panel for their input. Test materials are being collected and shipped to the University of Florida for testing to commence in July. This is a significant research project, and is being conducted over three calendar years.
