1" and 1.5" Nail Strip - Metal Roofing Panels
Western Seam® - Nail Strip Standing Seam Roofing
A nail strip roofing panel is a snap lock standing seam roof that does not have clips. The male flange has one inch slots that are spaced 6 inches apart and fastened directly to the roof deck.
It's the most economical and easiest to install of all the standing seam systems. However, you sacrifice a lot of performance when you eliminate the clips on this metal panel. It's still an expensive panel when compared to an exposed fastener panel for a corrugated metal roof. The cost savings are only about fifty cents per square foot versus a better performing product such as MS2® or Western Lock®
