Provide ribbed units, with abrasive filler strips projecting 1116 inch (1.5 mm) <br />above aluminum extrusion. <br />c. Provide solid-abrasive-type units without ribs. <br /> <br />3. Provide anchors for embedding units in concrete, either integral or applied to units. <br />4. Drill for mechanical anchors and countersink. Locate not more than 4 inches (100 mill) <br />from ends and not more than l2 inches (300 illm) o.c. <br /> <br />2.6 FINISHES <br /> <br />A. Comply with NAAMM's "Metal Finishes Manual for Architectural and Metal Products" for <br />recommendations for applying and designating fInishes. Finish metal fabrications after <br />assembly. <br /> <br />B. Steel and Iron Finishes: <br /> <br />1. Hot-dip galvanize items as indicated to comply with ASTM A 123/ A 123M or <br />ASTM A l53/A l53M as applicable. <br />2. Preparation for Shop Priming: Prepare uncoated ferrous-metal surfaces to comply with <br />requirements indicated below for environmental exposure conditions of installed metal <br />fabrications: <br /> <br />a. Exteriors (SSPC Zone lB)[ and Items Indicated to Receive Zinc-Rich Primer]: <br />SSPC-SP 6/NACE No.3, "Commercial Blast Cleaning." <br />b. Interiors (SSPC Zone lA): SSPC-SP 3, "Power Tool Cleaning." <br /> <br />3. Shop Priming: Apply shop primer to uncoated surfaces of metal fabrications, except <br />those with galvanized finishes and those to be embedded in concrete, sprayed-on <br />fIreproofing, or masonry, to comply with SSPC-PA 1, "Paint Application Specification <br />No.1: Shop, Field, and Maintenance Painting," for shop painting. <br /> <br />PART 3 - EXECUTION <br /> <br />3.1 INSTALLATION <br /> <br />A. General: Perform cutting, drilling, and fitting required for installing metal fabrications. Set <br />metal fabrications accurately in location, with edges and surfaces level, plumb, and true. <br /> <br />1. Fit exposed connections accurately together. Weld connections that are not to be left as <br />exposed joints but cannot be shop welded. Do not weld, cut, or abrade surfaces of <br />exterior units that have been hot-dip galvanized after fabrication. <br />2. Provide anchorage devices and fasteners where metal fabrications are required to be <br />fastened to in-place construction. <br />3. Provide temporary bracing or anchors in formwork for items that are to be built into <br />concrete, masonry, or similar construction. <br /> <br />METAL FABRICATIONS <br /> <br />05500 - 7 <br />
