�� un��on� ,��,��„ Panel Installation Guide Storaae if inetal is not to be used immediately,store inside in a well ventilated,dry location. Condensation or other moisture can form between the sheets during storage causing water stains or white rust which detract from the appearance of the product and may affect the product's usefu�life. Tra�ped moisture between sheets of p�inted metal can cause white rust to form under- neath the paint. This can cause the paint to flake off the panel immediately or several vears 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 8"with a supporting board underneath to prevent sagging. Fan the sheets slightly at the bottom to allow for air circulation. Keep the sheets off of the ground with an insulator such as wood. Anv outdoor storage is at the customer's own risk. If outdoor storage cannot be avoided,protect the metal using a canvas cover or waterproof paper. N�ver cover the metal with �lastic as this will cause condensation to form. Some Safety Precautions Always wear heavy gloves when working with steel panels to avoid cuts from sharp edges.When cutting or drilling steel panels, always wear safety glasses and sweep off any metal shavings immediately to prevent eye injury from flying metal fragments.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 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 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 of material thinner than 29 gauge. General Installation Information Insure that the structure is square and true before beginning panel installation.Ifthe structure is not square,the panels will not 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 recommended. Moisture released from the damp lumber may damage the metal panels. Nails installed in green or damp lumber may back out.Remove any loose meta�shavings left on the roof surface immediately to prevent corrosion.After install- ing roof,remove any debris such as leaves or dirt to prevent moisture from getting trapped on panels. Do not install in direct contact with chemically treated lumber. Fasteninq If you wish to predrill fastener holes,use a cover sheet to prevent hot shavings from sticking to panels. 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 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 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 to fill the hole.
