3 T-Rib Architectural Roofing T-RIB SSR SYSTEM General Notes and Installation Recommendations A. GENERAL NOTES 1. This booklet has been prepared to assist the designer and installer with various recommended details and installation procedures. Each project usually requires its own specially designed details. The details included can be used as a guide in designing project details. 2. Each roof panel is manufactured with four (4) minor stiffening ribs in the flat area to minimize oil-canning. However, due to the limitations of commercially available metals, some oil-canning should be anticipated and is not cause for rejection. 3. The erection of the T-Rib roof system can begin at either end of the building. 4. Whenever possible, workers should walk on the panel ribs rather than the flat of the panel. Boards or plywood should be placed over panels in areas which receive excessive foot traffic (such as roof top equipment, skylights, etc.). 5. Flashings must lap a minimum of 6". Treat flashing endlaps similar to a panel endlap detail using two rows of sealant tape with stitch screws 4" o.c. maximum. 6. Sealants: (a) Quality long-life butyl sealants work best as a gasket sandwiched between two pieces of metal. (b) One part polyurethane sealants are recommended when voids must be filled. 9. Jobsite handling: (a) Panel crates must be lifted at bundle block locations. (b) Do NOT lift material with ropes or wires. (c) Do NOT lift panels greater than 25'-0" long without a spreader bar. (d) Do NOT lift panels from ends while flat. DO lift panels on edge. B. PROPER STORAGE If the material is not to be used immediately, it should be stored in a dry place where little moisture can contact it. Moisture (from rain, snow, condensation, etc.) trapped between pieces of material may cause water stains or white rust which can affect the service life of the material and will detract from its appearance. To avoid staining or white rust, store the material in a well ventilated, dry area. Break the steel strapping bands used for shipment and store the material stacks material in an inclined position. If outdoor storage cannot be avoided, protect the material with a canvas or waterproof paper cover. Do not use plastic which can cause condensation. Keep the material off the ground in an inclined position with an insulator such as wood. It is the responsibility of the contractor to insure that all materials are properly stored at the jobsite. C. INSTALLATION PROCEDURES 1. Check the structural support system to be sure it is straight and square and that the tops of all members are in the same plane. Vertical camber in roof supports can cause water to pool on low pitched roofs. Misaligned structures can greatly increase the amount and degree of oil-canning. 2. Fasten each clip to the roof support member with the appropriate screw fastener. Clips are furnished pre-drilled to accept #12 screws. 3. For applications requiring endlaps, install the first panel (down-slope panel) like a normal panel. Prior to installing the upslope panel, place the back-up plate onto the installed downslope panel. Position the endlap sealant tape and place the upslope panel into position. Install the upslope panel as outlined in the endlap details. Secure the endlap with four (4) self-drilling, self-tapping screws, as shown on the detail. Connect all beads of sealant prior to placement of the cap-lock at panel endlaps. For ease of installation, install the clip at the endlap prior to installing the remaining clips on the upslope panel. D. FINAL CAP STRIP SEAMING 1. The cap strip seaming with the electric closure machine is begun after all other erection sequences are complete. 2. Remove closure machine from shipping box. 3. Install handle in position on motor mount stanchion. Insert clevis pin with washer through pivot holes. Insert retaining washer and spring pin. 4. To operate, use an approved electrical cord and plug into a 115 volt A.C. source. 5. Determine direction of operation and starting location on roof panel assembly. 6. Open seaming dies by moving lock lever to unlock position. At same time, raise handle of closing mechanism opening seaming dies to fully open position, approximately 30 degrees to each side of closure machine. 7. Lift closure machine and place in position where cap strip has been hand seamed. Insure front and rear guide blocks are aligned with panel ribs, are properly seated, and cam followers are along the sides of the cap strip. 8. Close seaming dies by moving lock lever into lock position. 9. Turn electric switch on, machine will begin seaming cap strip. 10.Operator should maintain alignment to panel ribs at same time applying slight forward pressure to assist movement along roof panel rib. 11. Upon reaching end of panel ribs, turn power switch off. Never install or remove closure machine while running. 12. Open seaming dies by moving lock lever to unlock position, releasing lock on left side of base platform, at same time raise handle of closing mechanism. 13. Position closure machine on next area of ribs to be seamed. Do not let closure machine sit directly on top of panels or it may mar the finish. 14. It is suggested that the closure machine be placed approximately 3 feet from the ridge and faced toward it and then seamed. Machine is then turned 180 degrees and seaming to the eave is completed. 15. The closure machine is not self-propelled but requires some pushing. A slightly firmer push may be needed at clip locations. 16. Inspect each seam after completion. Machine may be re-run over seam if required. 4

4 HEM LENGTHS The length of the hem at the end of a panel will vary with the change in temperature that the panel experiences and the length of the panel. Unless a more exact analysis of the temperature during installation compared to the maximum and minimum anticipated temperature is conducted, use the following equation and Thermal Movement Table. When installing panels, be sure to leave room at the end of the panel that will experience movement for the "starting gap" which is the required air space (X) between the panel and cleat.

12 T-Rib panels can be installed over a variety of substrates and can accomodate most insulation requirements. Continuous horizontal members are required for roof clip attachment and must be spaced to meet loading requirements. The horizontal members must have a flat surface at least as wide as the clip. Two fasteners per clip are required. Because T-Rib is a type of standing seam roof that accommodates thermal movement, the roof panels will not act as a diaphragm for wind design. Therefore, bracing is required to resist wind loads. PLYWOOD CLIP OPEN FRAMING CLIP 30lb.
