<br />too] marks and that is true to line and levels indicated, with exposed edges folded
<br />back to form hems.
<br />2.4.4 Seams: Fabricate nonmoving seams in sheet metal with flat -lock seams. Tin edges
<br />to be seamed, form seams, and solder.
<br />2.4.5 Expansion Provisions: Space movementjoints at maximum of 10 feet (3 in) with no
<br />joints allowed within 24 inches (610 mm) of corner or intersection. Where lapped
<br />or bayonet -type expansion provisions in Work cannot be used or would not be
<br />sufficiently weatherproof and waterproof, form expansion joints of intermeshing
<br />hooked flanges, not less than I inch (25 mm) deep, filled with mastic sealant
<br />(concealed within joints),
<br />2.4.6 Sealed Joints: Form nonexpansion, but movable, joints in metal to accommodate
<br />elastomeric sealant to comply with SMACNA standards.
<br />2.4.7 Separate metal from noncompatible metal or corrosive substrates by coating
<br />concealed surfaces at locations of contact with asphalt mastic or other permanent
<br />separation as recommended by manufacturer.
<br />2.4.8 Conceal fasteners and ex . . .
<br />,parision provisions where possible. Exposed fasteners are
<br />not allowed on faces of sheet metal exposed to public view.
<br />2.4.9 Fabricate cleats and attachment devices from same material as sheet metal
<br />component being anchored or from compatible, noncorrosive metal recommended
<br />by sheet metal manufacturer. .
<br />2.4.9.1 Size� As recommended by SMACNA manual or sheet metal
<br />manufacturer for application but never less than thickness of metal being
<br />secured.
<br />2.5 � Sheet Metal Fabrications
<br />2.5.1 General� Fabricate sheet metal items in thickness or weight needed to comply with
<br />performance requirements but not less than that listed below for each application
<br />and metal.
<br />2.5.2 Exposed Trim: Fabricate from the following material:
<br />Aluminum: 0.050 inch (1.2 mm) thick.
<br />2.5.3 Drip Edges: Fabricate from the following material:
<br />Aluminum: 0.0320 inch (0.8 mm) thick.
<br />2.5.4 Equipment Support Flashing: Fabricate from the following material:
<br />StainlessSteel: 0.0187 inch (0.5 mm) thick.
<br />2.6. Aluminum Extrusion Fabrications
<br />2-6.1 Aluminum Extrusion Units Fabricate extruded -aluminum running units with
<br />formed or extruded- aluminum joint covers for installation behind main members
<br />where possible, Fabricate mitered and welded corner units.
<br />2.7. Aluminum Finishes
<br />2.7.1 General: Comply with Aluminum Association's (AA) "Designation System for
<br />Aluminum Finishes" for finish designations and application recommendations.
<br />2.7.2 High -Performance Organic Coating Finish: AA-Cl2C42RIx (Chemical Finish -
<br />cleaned with inhibited chemicals, Chemical Finish: acid
<br />chromate -fluoride -phosphate conversion coating; Organic Coating: as specified
<br />below). Prepare, pretreat, and apply coating to exposed metal surfaces to comply
<br />with coating and resin manufacturer's instructions.
<br />2.7.2.1 Fluoropolymer 2-Coat Coating System: Manufacturer's standard 2-coat,
<br />thermocured system composed of specially formulated inhibitive primer
<br />and fluoropolymer color topcoat containing not less than 70 percent
<br />polyvinylidene fluoride resin by weight; complying with AAMA 605.2.
<br />3. Execution
<br />3.1. Examination
<br />3.1.1 Examine substrates and conditions under which sheet metal flashing and trim are to
<br />be installed and verify that Work may properly commence. Do not proceed with
<br />installation until unsatisfactory conditions have been corrected.
<br />3.2. Installation I
<br />1
<br />3.2.1 General � Unless otherwise indicated, install sheet metal flashing and trim to comply
<br />with performance requirements, manufacturer's installation instructions, and
<br />SMACNA's "Architectural Sheet Metal Manual. " Anchor units of Work securely in
<br />place by methods indicated, providing for thermal expansion of metal units, conceal
<br />fasteners where possible, and set units true to line and level as indicated. Install
<br />Work with laps, joints, and seams that will be permanently watertight and
<br />weatherproof
<br />3.2.2 Install exposed sheet metal Work that is without excessive oil canning, buckling,
<br />and tool marks and that is true to line and levels indicated, with exposed edges
<br />folded back to form hems. Install sheet metal flashing and trim to fit substrates and
<br />to result in waterproof and weather -resistant performance. Verify shapes and
<br />dimensions of surfaces to be covered before fabricating sheet metal.
<br />3.2.3 Roof -Edge Flashings: Secure metal flashings at roof edges according to FM Loss
<br />Prevention Data Sheet 1-49 for specified wind zone.
<br />3.2.4 Expansion Provisions- Provide for thermal expansion of exposed sheet metal Work.
<br />Space movement joints at maximum of 10 feet (3 in) with no joints allowed within
<br />24 inches (610 mm) of comer or intersection. Where lapped or bayonet -type
<br />expansion provisions in Work cannot be used or would not be sufficiently
<br />weatherproof and waterproof, form expansion joints of intermeshing hooked
<br />flanges, not less than I inch (25 mm) deep, filled with mastic sealant (concealed
<br />within joints).
<br />3.2.5 Soldered Joints: Clean surfaces to be soldered, removing oils and foreign matter.
<br />Pretin edges of sheets to be soldered to a width of 1-1/2 inches (38 mm), except
<br />where pretinned surface would show in finished Work.
<br />3.2.5.1 Do not solder the following metals:
<br />Aluminum
<br />3.2.5.2 Do not use torches for soldering. Heat surfaces to receive solder and flow
<br />solder into joint. Fill joint completely. Completely remove flux and
<br />spatter from exposed surfaces.
