Fabricator to utilize specified fonts, digitally produced. No hand cut lettering. <br />D. Seams and Joints <br />Welded joints shall be ground, filled and finished flush and smooth with <br />adjacent work. Such seams shall be invisible after final finish has been <br />applied. Spot welded joints shall not be visible on exterior of signs after final <br />finish has been applied. No gaps, light leaks, waves, or oil canning will be <br />permitted in Work. <br />E. Metal Signs and Supports <br />Fabricate exposed surfaces uniformly flat and smooth, without distortion, <br />pitting, or other blemishes. Form exposed metal edges to a smooth radius. <br />Grind exposed welds and rough areas to make flush with adjacent smooth <br />surfaces. <br />F. Welding <br />Make welds continuous. Comply with American Welding Society, Aluminum <br />Association, and Copper Development Association standards or equivalent, <br />for the type of metal. Provide the alloy and type required for strength, <br />workability, compatibility and color match after grinding smooth and finishing <br />the fabricated product. <br />G. Fasteners <br />Provide tamper -proof bolts, nuts, screws, washers, anchors, and other <br />devices required to complete the work. Use same basic metal alloy as the <br />metal fastened, and finished to match color and texture. Use stainless steel <br />300 series alloy where joining dissimilar materials and weather seal. Use <br />exposed fasteners only where indicated. Perform drilling and tapping at shop. <br />Provide adhesive, sealant, and other necessary materials as specified by <br />Designer /Client. <br />H. Dissimilar Materials <br />Where metal surfaces will be in contact with dissimilar materials, coat the <br />surfaces with epoxy paint or provide other means of dielectric separation as <br />recommended by Fabricator to prevent galvanic corrosion, separate all <br />ferrous and nonferrous metals with nonconductive gaskets, provide stainless <br />steel fasteners to secure ferrous to nonferrous metals. <br />I. Hardware <br />Provide all incidental hardware necessary for the proper functioning of signs. <br />External hardware shall conform to the external appearance of the sign, and <br />be tamper - proof. All hardware to be stainless steel non - oxidizing material <br />J. Castings Exposed surfaces uniformly free from porosity and roughness. <br />' Edges filled and ground smooth. Faces chemically etched and mechanically <br />polished for specified finish. <br />02/06 6 03-4122.E <br />
