KEEP METAL ROOFING PRODUCT MATERIALS DRY <br /> Paint and finishes of METAL SYSTEMS, INC. panels and trim are designed <br /> to endure severe rain and wet weather conditions. CAUTION: Neither paint, <br /> galvanized, nor Galvalume finishes, are designed to be in continuous contact <br /> with water or condensation for long periods of time. <br /> Damage will result if uninstalled panels or trim are allowed to remain wet <br /> in storage. Be sure to store material that will not be installed immediately in a <br /> dry location. Wet material should be air -dried and re- stacked if installation <br /> immediate. <br /> NOTE: Plastic should not be used to cover metal panels. <br /> HOW TO FIGURE SCREWS: <br /> On low-pitched roofs, butyl tape or caulk should be applied at the panel <br /> lap to keep water from overflowing the lap. <br /> For 2 -foot spacing between rows of screws, multiply the total linear feet of <br /> metal times 2.7. <br /> Example; Ifyour order is 1500 feet of 9 -5 Rib roofing. <br /> 1500 x 2.7= 4050 screws would be applicable for fastening. <br /> Contact your METAL SYSTEMS, INC. representative for a free estimate. <br /> Metal roofing application can be aided by pre- drilling panels, allowing screws <br /> to go quickly and accurately into the desired spacing. Pre - drilling will work <br /> provided that pilot holes are placed accurately in the proper locations on <br /> panels. <br /> Purlin spacing must be uniform and carefully measured. <br /> HIGH VELOCITY WIND ZONES <br /> For solid decking, at least 1 %2 - inch structural plywood or OSB (5/8" for any <br /> High velocity wind zone of 120 and above) supported on rafters at a <br /> max of 24" o center. Battens: 9-5 Rib Metal Roofing can be separated <br /> from the moisture barrier by minimum, nominal 1 "x3" yellow pine battens <br /> s on maxim 7'4" c o r accordi t : SCE; 7 -98 raicuia ions were <br /> applicable. <br />
