<br />METAL BUILDING SYSTEMS 133419 - 12
<br />2.7 ACCESSORIES
<br />A. General: Provide accessories as standard with metal building system manufacturer and as
<br />specified. Fabricate and finish accessories at the factory to greatest extent possible, by
<br />manufacturer's standard procedures and processes. Comply with indicated profiles and with
<br />dimensional and structural requirements.
<br />1. Form exposed sheet metal accessories that are without excessive oil-canning, buckling, and
<br />tool marks and that are true to line and levels indicated, with exposed edges folded back to
<br />form hems.
<br />B. Roof Panel Accessories: Provide components required for a complete metal roof panel assembly
<br />including copings, fasciae, corner units, ridge closures, clips, sealants, gaskets, fillers, closure
<br />strips, and similar items. Match material and finish of metal roof panels unless otherwise
<br />indicated.
<br />1. Closures: Provide closures at eaves and ridges, fabricated of same material as metal roof
<br />panels.
<br />2. Clips: Manufacturer's standard, formed from stainless steel sheet, designed to withstand
<br />negative-load requirements.
<br />3. Cleats: Manufacturer's standard, mechanically seamed cleats formed from stainless steel
<br />sheet or nylon-coated aluminum sheet.
<br />4. Backing Plates: Provide metal backing plates at panel end splices, fabricated from material
<br />recommended by manufacturer.
<br />5. Closure Strips: Closed-cell, expanded, cellular, rubber or crosslinked, polyolefin-foam or
<br />closed-cell laminated polyethylene; minimum 1-inch- thick, flexible closure strips; cut or
<br />premolded to match metal roof panel profile. Provide closure strips where indicated or
<br />necessary to ensure weathertight construction.
<br />6. Thermal Spacer Blocks: Where metal panels attach directly to purlins, provide thermal
<br />spacer blocks of thickness required to provide 1-inch standoff; fabricated from extruded
<br />polystyrene.
<br />C. Flashing and Trim: Zinc-coated (galvanized) or aluminum-zinc alloy-coated steel sheet, 0.018-
<br />inch nominal uncoated steel thickness, prepainted with coil coating; finished to match adjacent
<br />metal panels.
<br />1. Provide flashing and trim as required to seal against weather and to provide finished
<br />appearance. Locations include, but are not limited to, eaves, rakes, corners, bases, framed
<br />openings, ridges, fasciae, and fillers.
<br />2. Opening Trim: Zinc-coated (galvanized) or aluminum-zinc alloy-coated steel sheet, 0.018-
<br />inch nominal uncoated steel thickness, prepainted with coil coating. Trim head and jamb
<br />of door openings, and head, jamb, and sill of other openings.
<br />D. Gutters: Zinc-coated (galvanized) or aluminum-zinc alloy-coated steel sheet, 0.018-inch nominal
<br />uncoated steel thickness, prepainted with coil coating; finished to match roof fascia and rake trim.
<br />Match profile of gable trim, complete with end pieces, outlet tubes, and other special pieces as
<br />required. Fabricate in minimum 96-inch- long sections, sized according to SMACNA's
<br />"Architectural Sheet Metal Manual."
<br />1. Gutter Supports: Fabricated from same material and finish as gutters.
