According to Maze, Stormguard Coil Roofing Nails are made in the U.S. using at least 85 percent recycled steel and zinc. The company also says it reclaims almost all of the waste products — steel, zinc, and acids — generated by the manufacturing process and uses only recycled paper for packaging. A 30-coil (3,600-nail) carton costs $115. The nails are also available in hand-drive.
