UNION <br /> (bFiRLIGATIVf.'CWIPAM' <br /> Panel Installation Guide <br /> Storaae <br /> If inetal is not to be used immediately,store inside in a well venti(ated dry location.Condensation or other moisture can form <br /> between the sheets during storage causing water stains or white rust which detract from the appearance of the product and <br /> may affect the product's useful life. Trapped moisture between sheets of painted metal can cause white rust to form under <br /> neath the paint. This can cause the paint to flake off the panel immediately or several years later. To prevent white rust and <br /> staining,break the shipping bands on the material. Store the material on end or on an incline of at least 8"with a supporting <br /> board underneath to prevent sagging. Fan the sheets slightly at the bottom to allow for air circulation. Keep the sheets ofF of <br /> the ground with an insulator such as wood. Any outdoor storage is at the customer's own risk. If outdoor storage cannot be <br /> avoided,protect the metal using a canvas cover or waterproof paper. Never cover the metal with plastic as this will cause <br /> 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, <br /> always wear safety glasses and sweep off any metal shavings immediately to prevent eye injury from flying metal fragments. If <br /> you must walk on a metal roof,take great care. Metal pane�s can become slippery,so always wear shoes with non-slip soles. <br /> Avoid working on metal roofs during wet conditions when the panels can become extremely slippery.Walking or standing on <br /> a metal roof which does not have a plywood or other deck beneath it is not recommended. However,if you must do so,always <br /> walk�on the purlins,never between. Do not for any reason walk on a roof made of material thinner 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 <br /> properly seal at the sidelaps.Start the first panel square to eave by using 3,4,5 Triangle Method.Green or damp lumber is not <br /> recommended. Moisture released from the damp lumber may damage the metal panels. Nails installed in green or damp <br /> lumber may back out.Remove any loose metal shavings left on the roof surface immediately to prevent corrosion.After install- <br /> ing roof,remove any debris such as leaves or dirt to prevent moisture from getting trapped on panels. Do not install in direct <br /> contact with chemically treated lumber. <br /> Fastenina I <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 <br /> below. Fasteners should be applied at every purlin. Drive the fastener so that the washer is compressed securely <br /> against the metal. Do not over drive the fastener as this will form a dimple that can collect water and cause <br /> leakage. Do not leave any loose fasteners that have missed the purlin. Use a#14 stitch screw or caulk to fill the <br /> hole. <br /> Figure#1-Fastening Patterns for MasterRib� F'igure#3 <br /> � Orersia0 <br /> !'�CONtMENDED FASTENtNG PA7"TERN FOR1�/xn� nnriziphoning <br /> 3/a' ��� <br /> � � '� <br /> SCREW FAST'ENERS—EAVE,RIDGE,&ENDIAPS <br /> SCREW FASTENERS—lNTERMEDlATESUPPORTS <br /> 4 <br /> `ti <br />
