<br />... ~ <br /> <br />Installation Instructions for MasterRib"~ <br /> <br />Stora:~e <br />If metal is not to be used immediately, store inside in a well ventilated..d1y10cation.Condensation or other moisture can form between the <br />sheets during storage causing water stains or white rust which detract from the appearance of the product and may affect the product's useful <br />life. TrapJled moisture between sheets of oainted metal can cause white rust to form underneath the oaint. This can cause the paint to <br />flake 0" the paneLimmediatelv or severai vears later. To prevent white rust and staining, break the shipping bands on the material. Store <br />the material on end or on an incline ofafleast8"withasupporting board underneath to prevent sagging. Fan the sheets slightly at the bottom <br />to allow for air circulation. Keep the sheets off of the ground with an insulator such as wood. Any outdoor storage is atthe customer's own <br />risk. If outdoor storage cannot be avoided, protect the metal using a canvas cover or waterproof paper. Never cover the metal with plastic as <br />this will cause condensation to form. <br /> <br />Some SafetvPrecautions <br />Always wear heavy gloves when working with steel panels to avoid cuts from sharp edges. When cutting or drilling steel panels, always wear <br />safety glasses and sweep off any metal shavings immediately to prevent eye injury from flying metal fragments. <br />If you must walk on a metalroof,take great care. Metal panels can become slippery, so always wear shoes with non-slip soles. Avoid working <br />on metal roofsduringwetconditions when the panels can become extremely slippery. Walking or standing on a metal roof which does not have <br />a plywood or other deck beneath iUs not recommended. However, if you must do so, always walk on the purlins, never between. Do not for <br />any reason walk on a roof made of material less thick than 29 gauge. <br /> <br />General Installation ,Information <br />Insure that the structure is square and true before beginning panel installation. If the structure is not square, the panels will not properly seal <br />at the side laps. <br />Green or damp lumber is not recommended. Moisture released from the damp lumber may damage the metal panels. Nails installed in green <br />or damp lumber may back out. <br />The prevention of steel debris staining is the responsibility of the installer. The recommended tools for on site cutting are profile shears, hand <br />shears, or electric nibblers. Friction saws and abrasive discs should not be used to cut panels. <br />Remove any loose metal shavings left on roof surface immediately to prevent corrosion. Afterinstalling roof, remove any debris such as leaves <br />or dirt to prevent moisture from getting trapped on panels. P J REVIEWED <br />Fastenin~ DATE <br /> <br />If you wish to predrill fastener holes, use a cover sheet to prevent hot shavings from sticking to ~~~~NG EPT APPROVE <br />Screws -Forbest results use a I -112" double washeredwood screw in the flat of the panel as shown in the illustration below. Fasteners shou e <br />applied at everypurlin. Drive the fastener so that the washer is compressed securely ,against the metal. Do not over drive the fastener <br />as this will forma dimple that can collect water and cause leakage. Do not leave any loose fasteners that have missed the purlin. Use <br />a #14 stitch screw or caulk to fill the hole. <br /> <br /> <br />Nails - Ifthe panels are nailed, use 1':3/4" ring-shanked neoprenewashered nails. Nail into the crown of the major ribs of the panel as <br />illustrated below, (See Figure #2 below). NOTE: If rigid insulation is used directly underthe panel, the fastener length needs <br /> <br />to <br /> <br />be increased to allow a minimum of 1" penetration into the wood. General installation instructions listed above for screws also <br />apply to nails. Do not apply nails into flat area of panel. <br /> <br />Fil:ure #l-FasteningPatterns for MasterRibilY <br />RECOMMENDED FASTENING PATTERN FOR 1-1/2" SCREWS <br /> <br />~-~~-~ <br />SCREW FASTENERS -EAVE, RIDGE, & ENDLAPS <br /> <br />~ - -r^ ~ ~-------tA- <br />SCREW FASTENERS - INTERMEDIATE SUPPORTS <br /> <br />Fil:ure #2 - (Nails only) <br /> <br />UNDERDRIVEN CORRECT OVER DRIVEN <br /> <br />..t1'..r1'x ./]\. <br /> <br />Fieure #3 <br /> <br />A- <br /> <br />FASTENING PATTERN FOR 1-3/4" NAILS <br />A__A_~A_ <br /> <br />~~ <br /> <br />7 <br /> <br />T <br />3/4" <br />t <br /> <br />~ OVERSIZED <br />~ANTISIPHONING <br />CHANNEL <br />7 <br /> <br />- <br /> <br /> <br /> <br />... <br /> <br />Metal Construction Association <br /> <br />MEMBER <br /> <br />~ <br />-, <br /> <br /> <br />~ IU'LD'" ~ <br /> <br />SPENCER <br />STEEL SUPPLY <br /> <br />ANDERSON <br />STEEL SUPPLY <br /> <br />IJI:FIRlJGAllEo:Jrl.1FAN'f <br />Fayetteville, NC <br />www.unioncorrugating.com <br /> <br />TIFTON ORANGE UNICO <br />STEEL PRODUCTS STEEL ROOFING METAL PRODUCTS <br /> <br />VICKSBURG <br />METAL PRODUCTS <br /> <br />DAYTON <br />METALS <br />
