PART 2 PRODUCT

2.01  MANUFACTURERS

THE THREE MANUFACTURERS LISTED BELOW ARE COMPARABLE IN QUALITY.  ADD OTHER MANUFACTURERS ONLY AFTER CAREFUL REVIEW OF THEIR FABRICATION TECHNIQUES AND WORKMANSHIP.

    1. The design is based on products fabricated by: Peachtree Protective Covers, Inc., 3255 South Sweetwater Rd., Lithia Springs, GA 30122, 770-439-2120, fax 770-439-2122.
      1. Comparable products by the following manufacturers also will be acceptable:
        1. Dittmer Architectural Aluminum.
        2. Avadek Walkway Cover Systems.
      2. Substitutions: Comparable products of other manufacturers will be considered under standard substitution procedures.

2.02  MATERIALS

    1. Aluminum Members: Extruded aluminum, ASTM B 221, 6063 alloy, T6 temper.
    2. Fasteners: Aluminum, 18-8 stainless steel, or 300 series stainless steel.
    3. Protective Coating for Aluminum Columns Embedded in Concrete: Clear acrylic.
    4. Gaskets: Dry seal santoprene pressure type.
    5. Aluminum Flashing: ASTM B 209, Type 3003 H14, 0.040 inch, minimum.

2.04  FABRICATION

    1. General:
      1. Shop Assembly: Assemble components in shop to greatest extent possible to minimize field assembly.
      2. Welding: In accordance with ANSI/AWS D1.2.
      3. Gutter Frame Construction: Factory assemble gutter fascia frames to form a one-piece welded frame. Make welds smooth and uniform using an inert gas shielded arc. Perform suitable edge preparation to assure 100% penetration. Grind welds only where interfering with adjoining structure to allow for flush connection. Field welding is not permitted. Gutter frames constructed by mechanically fastening components together are not acceptable.
      4. Deck Construction: Fabricate from extruded modules that interlock in a self-flashing manner. Positively fasten interlocking joints creating a monolithic structural unit capable of developing the full strength of the sections. The fastenings must have minimum shear strength of 350 pounds each.
    2. Beams: Where applicable provide open-top tubular extrusion, top edges thickened for strength and designed to receive deck members in self-flashing manner.
    3. Deck: Extruded self-flashing sections interlocking into a composite unit.
    4. Gutter Fascia: Where applicable provide “j-shaped” gutter fascia capable in manufacturer’s standard sizes.
    5. Fascia: Where applicable provide manufacturer’s standard fascia in standard sizes.
    6. Hanger Assemblies: Provide extruded aluminum hanger rods in manufacturer’s standard shapes and sized to meet the loads seen by canopy.
