Die set ends allow for the roof deck to be easily end lapped to increase the diaphragm stiffness. The die set swages the top flange and webs of the steel deck which allows the top sheet of end lapped deck to nest tightly over the bottom sheet. When deck is not die set, the installer may have to hammer the deck to get the ends to nest together tightly to ensure good quality connections. The die set ends are standard for B-36 roof deck. B-36 is optionally available without die set ends. Die set ends are not available on other roof deck products.
