Intermediate powder primer (optional) 4. Finish coat – Factory applied acrylic polyurethane. 2. FABRICATION A. All components are factory formed to custom designed profiles. B. Only the structural sections of the vertical profiles are fixed to the surrounding structure. All other horizontal structural profiles are interconnected using factory fitted shear blocks to the edge of the verticals. C. All framing components are shipped in “knocked-down” (KD) form to be assembled on-site by experienced personnel. D. All anchor and spigot preparations shall be done in the factory. E. Anchoring of wall system shall be per approved shop drawings to suit the surrounding structure. F. Glazing 1. Wall system shall be designed for outside pressure plate type glazing. 2. Install push fit gaskets and weather seal joints as per installation instructions. 3. Provide continuous screw on 10 gauge steel face clamps. 4. Screw attached face clamps into the glazing channel in the field. Fixing centers at no more than 12”. 5. Snap fit the cover onto the face clamps. 6. Glazing accessories per manufacturer of tested glazing material. Glazing blocks to be sized to achieve as tested edge conditions of glass. 3. FACTORY FINISHING A. Shot Blasting 1. Before any machining or welding is performed, all hot-rolled steel sections shall be cleaned by shot blasting to remove any loose or mill scale. 7000 SERIESTM 60, 90 AND 120 MINUTE FIRE RATED GLAZED WALL SYTEMS B. E-Coat Pretreatment and Prime Painting 1. After fabrication, windows, mullions, covers, and trim shall be subjected to an advanced 11-stage pretreatment process to thoroughly clean and prepare the substrates for e-coat. a. Caustic soap spray cleaning b. Caustic soap emersion cleaning c. Cold water rinse, emersion d. Acid-etch pickling e. Cold water rinse, emersion f. Cold water rinse, emersion g. Rinse conditioner/ grain refiner, emersion h. Zinc phosphate application, emersion i. Cold water rinse, emersion j. Non-chrome sealer, emersion k. Reverse osmosis filtered water rinse, emersion 2. Following pretreatment, windows and accessories are immersed into a cathodic epoxy primer of PPG Powercron®8000 or equivalent for the length of time required to coat all surfaces to a dry film thickness of minimum 0.8-1.2 mils. The use of spray or non-cathodic dip primers shall not be acceptable. a. All excess paint and runs are then removed by post rinse stages consisting of: b. Spray rinse of ultra-filtered RO water c. Immersion in a rinse of ultra-filtered RO water for 3 minutes d. Spray rinse of ultra-filtered RO water 3. The material is then oven baked for 20 minutes at 325° (degrees) F metal temperature 4. The material is then cooled in preparation for the optional powder primer coat or final finish coat. C. Powder Intermediate Primer (Coastal or optional applications) 1. Following the E-Coat pretreatment/ priming process, windows and accessories are coated with a urethane polyester powdercoat primer that provides additional protection against abrasion and corrosion. 2. Powder coating shall be applied by electrostatic spray over the cured E-Coat to a dry film thickness of 2.0-3.0 mil. 3. The parts are then baked at a temperature of 375°F to completely cure the gray urethane polyester coating. The resulting coating provides a durable finish which is resistant to chipping, scratching and general abrasion experienced during the installation process. Additional fused layer of protection also provides additional protection from harmful environments (i.e. high humidity and coastal salt air environments). 4. The primer is available in both smooth and textured finishes. 5. After cooling, the components are ready for their finish coat. 7000 SERIESTM 60, 90 AND 120 MINUTE FIRE RATED GLAZED WALL SYTEMS 6. Powder coatings are not intended for final finish and must be top coated with a polyurethane finish paint. D. Ultrathane Finish Top coat 1. Following the primer coat(s), all windows and accessories are given a spray coat of acrylic polyurethane and oven baked at 225°F for 15 minutes to dry film thickness of 1.5-2.0 mils. 2. The combined overall dry film thickness of the coatings shall be 2.3-3.2 mils (if no powder intermediate coat) and 4.3-6.2 (with the powder intermediate coat). 3. The architect shall choose from an unlimited color selection. Color matching is available upon request, along with clear coats. Some colors may require clear coats for added protection.
