2.3 FASTENERS <br />A. General: Unless otherwise indicated, provide Type 316 stainless-steel fasteners for exterior use and zinc - <br />plated fasteners with coating complying with ASTM B 633 or ASTM F 1941 (ASTM F 1941M), <br />Class Fe/Zn 5, at exterior walls. Select fasteners for type, grade, and class required. <br />1. Provide stainless-steel fasteners for fastening aluminum. <br />2.4 MISCELLANEOUS MATERIALS <br />A. Epoxy Zinc -Rich Primer: Complying with MPI#20 and compatible with topcoat. <br />2.5 FABRICATION, GENERAL <br />A. Shop Assembly: Preassemble items in the shop to greatest extent possible. Disassemble units only as <br />necessary for shipping and handling limitations. Use connections that maintain structural value of joined <br />pieces. Clearly mark units for reassembly and coordinated installation. <br />B. Cut, drill, and punch metals cleanly and accurately. Remove burrs and ease edges to a radius of <br />approximately 1/32 inch (1 mm) unless otherwise indicated. Remove sharp or rough areas on exposed <br />surfaces. <br />C. Form bent -metal comers to smallest radius possible without causing grain separation or otherwise <br />impairing work. <br />D. Form exposed work with accurate angles and surfaces and straight edges. <br />E. Weld corners and seams continuously to comply with the following: <br />1. Use materials and methods that minimize distortion and develop strength and corrosion resistance <br />of base metals. <br />2. Obtain fusion without undercut or overlap. <br />3. Remove welding flux immediately. <br />4. At exposed connections, fmish exposed welds and surfaces smooth and blended so no roughness <br />shows after finishing and contour of welded surface matches that of adjacent surface. <br />F. Form exposed connections with hairline joints, flush and smooth, using concealed fasteners or welds <br />where possible. Where exposed fasteners are required, use Phillips flat -head (countersunk) fasteners <br />unless otherwise indicated. Locate joints where least conspicuous. <br />G. Fabricate seams and other connections that will be exposed to weather in a manner to exclude water. <br />Provide weep holes where water may accumulate. <br />H. Cut, reinforce, drill, and tap metal fabrications as indicated to receive finish hardware, screws, and similar <br />items. <br />I. Provide for anchorage of type indicated; coordinate with supporting structure. Space anchoring devices <br />to secure metal fabrications rigidly in place and to support indicated loads. <br />Wabasso Beach Park <br />Indian River County <br />DAA Project No. 6008 <br />05500-3 <br />�I <br />
