The Tuff-Rib® panel is an industry leader in strength and durability. This popular and versatile panel featuresclassic looks and is used in a wide range of applications including residential, commercial, andpost-frame buildings. Tuff-Rib® was designed with strong trapezoidal ribs to increase strength and easehandling and installation. In addition, the anti-siphoning channel on the under-lap provides extra leakresistance in the presence of extreme wind and rain loads.

Tuff-Rib® is available in many different paint colors and in both 26 and 29 gauge steel. It is also available inunpainted Galvalume® or in some cases unpainted galvanized. Our paint system and Galvalume® substrateare individually covered by a limited warranty. Please see our color chart for details on our paint system.

The Tuff-Rib® panel is available in 36” coverage. The panel has five major support ribs at ¾” high that addrigidity and strength to the panel.

If metal is not to be used immediately, store inside in a well ventilated, dry location. Condensation or other moisture can formbetween the sheets during storage causing water stains or white rust which detract from the appearance of the product andmay affect the product’s useful life. Trapped moisture between sheets of painted metal can cause white rust to form under-neath the paint. This can cause the paint to flake off the panel immediately or several years later. To prevent white rust andstaining, break the shipping bands on the material. Store the material on end or on an incline of at least 8” with a supportingboard underneath to prevent sagging. Fan the sheets slightly at the bottom to allow for air circulation. Keep the sheets off ofthe ground with an insulator such as wood. Any outdoor storage is at the customer’s own risk. If outdoor storage cannot beavoided, protect the metal using a canvas cover or waterproof paper. Never cover the metal with plastic as this will causecondensation to form.

Always wear protective gloves when working with steel panels to avoid cuts from sharp edges. When cutting or drilling steelpanels, always wear safety glasses and sweep off any metal shavings immediately to prevent eye injury from flying metalfragments. If you must walk on a metal roof, take great care. Metal panels can become slippery, so always wear shoes withnon-slip soles. Avoid working on metal roofs during wet conditions when the panels can become extremely slippery.

Insure that the structure is square and true before beginning panel installation. If the structure is not square, the panels willnot properly seal at the sidelaps. Start the first panel square to eave by using the 3, 4, 5 Triangle Method. Green or damplumber is not recommended. Moisture released from the damp lumber may damage the metal panels. Nails installed ingreen or damp lumber may back out. Remove any loose metal shavings left on the roof surface immediately to preventcorrosion. After installing roof, remove any debris such as leaves or dirt to prevent moisture from getting trapped on panels.

If you wish to predrill fastener holes, use a cover sheet to prevent hot shavings from sticking to panels. Screws - For bestresults, use a 1-1/2” washered wood screw in the flat of the panel as shown in the illustration below. Drive the fastener sothat the washer is compressed securely against the metal. Do not over drive the fastener as this will form a dimple thatcan collect water and cause leakage. Do not leave any loose fasteners that have missed the purlin. Use a #14 stitch screwor caulk to fill the hole.

Slopes of less than 2.5” on 12” are not recommended. For slopes of 2.5” on 12” or greater, end lap panels 6”. Side laps shouldface away from the prevailing wind. Lay the first sheet along the eave at the down-wind side of the roof, farthest away fromthe direction of the prevailing winds (See Figure #4). Install sheets in the sequence shown in Figure #4.

Allow an overhang a minimum of 1” at the eave to provide for a drip edge. Use inside closure at eave to prevent waterinfiltration, insect or bird infestation at openings. To protect against uplifting winds and to provide a finished appearance, applygable trim. Apply fasteners every 6”-10”. Optionally apply butyl tape as shown in Figure #6 along the top of lap ribs. Do notblock the siphon channel with the tape. Also an option: apply a 3/4” or 7/8” lap stitch screw into the crown of the rib to securethe side lap. This is especially a good idea on roofs with a slope less than 4:12.

Point A

Point B

Using two tape measures, locate point C by hookingone tap to a nail at point A and the second tapeto a nail at point B. Extend the tapes until they crossand meet at 4’ on the first tape and 5’ on the secondtape and place a temporary nail where 4’ and 5’ meet.

...the 4’ and 5’ measurements arethe 4 and 5 sides of the 3...4...5...triangle.

For larger 3...4...5...Triangles multipleeach side of the triangle by the desiredincrease in size. For example, if the roofpanels are 25’ from eave to ridge,multiply each side by a factor of 6 for an18’...24’...30’...Triangle. Obviously, thecloser the triangle vertical leg length isto matching the panel length, thegreater the squaring accuracy.

Hook a chalk line to point A and pull it inline with point C and mark a chalk line onthe roof deck.

This will be the square reference line for theTuff-Rib® panel installation.

Tuff-Rib®

Establish a line from point A to point B bytemporarily marking each point with anail. The line must be parallel to the eaveand in this example 3’ long (this is the 3side of the 3...4...5... Triangle).

Mark chalk lines parallel with the square referenceline out ahead of panel installation so that panelsquare can be checked as the panels are installed.Suggested line spacing is one foot beyond 3 panelswide or about 10 feet.

Check for square by measuring thedistance from the installed paneledge to the chalk line at both theeave and ridge. If themeasurements match, then theinstalled panels are square, if not,adjustments must be made tobring the panels back into square.
