Conclusion

The samples of Ring Shank 150 wire weld Coil Roofing Nails were tested in accordance with Florida Building Code TAS114 Appendix E Section 2 ASTM G 85, Annex A5. The samples were examined after 140 cycles (280 hours) and were found to have less than 5% surface corrosion, meeting the requirement of TAS 114 Appendix E section 2.6.1.1 of Florida Building Code for High Velocity Hurricane Zone. NOTE: The above results were obtained using the designated test methods, which indicates compliance with the performance requirements of the referenced specifications.
