Condensation or other moisture can form between the sheets during <br /> storage causing water stains or white rust which detract from the appearance of the product and may affect the product's useful life. napped moisture <br /> between sheets of�painted metal can cause white rust to form underneath the pain�This can cause the paint to flake off the uanel immediatelv or <br /> several years later.To prevent white rust and staining,break the shipping bands on the material. Store the material on end or on an incline of at least S" <br /> with a supporring boazd undemeath to prevent sagging. Fan the sheets slighfly at the bottom to allow for air circulation. Keep the sheets off of the ground <br /> with an insulator such as wood. Any outdoor stora�e is at the custor�er's own risk. If outdoor storage cannot be avoided,protect the m�l using a canvas <br /> cover or waterproof paper.Never cover the metal with�astic as this will cause condensation to form. <br /> Some Safety Precautions <br /> Always wear heavy gloves when working with steel panels to avoid cuts from sharp edges. When cutting or drilling steel panels, always wear safety <br /> glasses and sweep off any metal shavings immediately to prevent eye injury from flying metal fragments. <br /> If you must walk on a metal roof,take great care. Metal panels can become slippery,so always wear shoes with non-slip soles. Avoid working on metal <br /> roofs during wet conditions when the panels can become extremely slippery. Walking or standing on a metal roof which does not have a plywood or other <br /> deck beneath it is not recommended. However,if you must do so,always walk on the purlins,never between. Do not for any reason walk on a roof made <br /> of material less thick than 29 gauge. <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 at the side laps. <br /> Green or damp lumber is not recommended. Moisture released from damp lumber may damage the metal panels. Nails installed in green or damp lumber <br /> may back out. Green,wet,treated wood and fire retardant lumber should not come in contact with baze galvanized,Galvalume0,or prepainted steel. <br /> Galvanized and Galvalume�steel is compatible with ACQ(Alkaline Copper Quaternary)and CCA(Chromated CopperArsenate)pressure treated lumber <br /> used predominandy today. Plasric,insulation,duct tape,felt,bituminous paint,caulking,or gasket material may be used to separate panels from treated <br /> wood and dissimilaz metals. <br /> Remove any loose metal shavings left on roof surface immediately to prevent corrosion. The'prevenrion of steel debris staining is the responsibility of the <br /> installer. The recommended tools for on site cutting are profile sheazs,hand shears,or electric nibblers. Friction saws and abrasive discs should not be <br /> used to cut panels. . <br /> After installing the roof,remove any debris such as leaves or dirt to prevent moisture from getting trapped on the panels. <br /> . Fastenin� <br /> If you wish to predrill fastener holes,use a cover sheet to prevent hot shavings from sticking to panels. <br /> Screws-For best results use a 1-1/2"double washered wood screw in the flat of the panel as shown in the illustration below. Fasteners should be applied <br /> at every purlin. Drive the fastener so that the washer is compressed securely against the metal. Do not over drive the fastener as this will form <br /> a dimple that can collect water and cause leakage. Do not leave any loose fasteners that have missed the purlin.Use a#14 stitch screw or caulk <br /> to fill the hole. <br /> Nails- If the panels aze nailed,use 1-3/4"ring-shanked neoprene washered 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 under the panel,the fastener length needs to be <br /> increased to allow a minimum of 1"penetration into the wood. General installation instructions listed above for screws also apply to <br /> nails. Do not apply nails into flat area of panel. <br /> Figure#1 -Fastening Patterns for MasterRib� Figure#2-(Nails onlvl <br /> RECOMMENDED FASTENING PATTERN FOR 1-1/2"SCREWS <br /> UNDER DRIVEN CORRECT OVER DRIVEN <br /> +, + � . + ► + <br /> SCREW FASTENERS—EAVE,RIDGE,&ENDLAPS �� � <br /> T ` i�_ <br /> SCREW FASTENERS—INTERMEDIATE SUPPORTS Figure#3 <br /> FASTENING PATTERN FOR 1-3/4"NAII.S ,� OVERSIZED <br /> 3/4" '—ANTISIPHONING <br /> � j CHANNEL <br /> � MEMBER ' " <br /> S�� uniiont � � <br /> nie r�nEru •�� , <br /> BUILDINGCOMPONINTS CORRUGATING COMPANY <br /> INDU5TRYFOROVER t�7 � ' � <br /> ��� Fayetteville,1�C Metal ConsWction Association � � � ��' <br /> ww�:uruoncorrugating.com ��,���� <br /> SPENC�R r�NDERSON TIFTON O12ANGE �JrTICO VICKSBUI�G <br /> STEEL SUPPLY STEEL SUPPLY STEEL PRODUCTS STEEL ROOFING METAL PRODUCTS METAL PRODUCTS <br />
