All joints of the aluminum channel shall be welded with an inert gas shielded-arc welding process using 4043 electrode filler wire in accordance with good shop practice. The width of the filler wire shall be equal to the wall thickness of the channel being welded.

The top of the frame will have two 2” x 2” x .250” (53 x 53 x 6 mm) wall thickness channel members welded and fastened to the frame with stainless steel bolt, washer, lock nuts and cotter pins. The adjustable swing assembly will be attached to thesemembers.

b. Assembly:

A sign panel shall be fastened to both sides of the channel frame to make a double-faced unit. Each sign panel must be a continuous sheet, no vertical or horizontal splices to make up one panel.

The sign panels shall be affixed to the frame with 3/16” (5 mm) diameter blind pop rivets, alloy 5052, or a type approved by the City.

They must be aluminum approved. The exposed face of the rivet shall be of similar shade and compatible with face color of the finished sign.

The rivets shall be placed through the face of the sign with the wall of the channel placed against the back of the sign panel. Rivets shall be placed no closer than ½” (13 mm) from the edge of the sign panel and a maximum of 8” (200 mm) apart from one another. All rivets must penetrate the web of the channel frame for proper grip strength between sign panel and frame.

The swing hinge is attached to the 2” x 2” (53 x 53 mm) channel member with a ¼” (7 mm) stainless steel bolt and bronze bushing, and then secured with any lock nut.

4. Mounting Assemblies:

The top of the sign frame shall have two free swinging mounting brackets. They shall be of all aluminum, bronze, and stainless-steel parts. The 5” (125 mm) long stainless-steel bolt for fine adjustments shall have nuts and lock washers, or self-locking nuts and cotter key. Dampening springs are required. The bracket assembly shall permit the sign to swing perpendicular to the supporthardware.

The aluminum mounting brackets shall be adjustable MD Solutions Inc. Oscillating Mast Arm Bracket-Adj or approved equivalent (for example, ZAP Manufacturing Bracket Kit, Hawkins Adjustable Bracket Kit).

When installation of the sign to the mast arm is complete, the sign should swing freely 90 degrees in both directions when moved by the installer.

5. Finish:

The finished sign shall be flat within a ratio of 0.40” (10 mm) per linear foot when measured across the plane of each panel from opposite corners or at any location on the panel. All finished signs shall have a smooth flat surface without defects or objectionable marks of any kind on either the front or the back faces. All letters and designs shall be clearly cut and sharply defined.

The appearance of the sign face shall be uniform throughout and shall be free of wrinkles, gel, hard spots, streaks, extrusion marks, air bubbles or blemishes that may impair the serviceability, detract from the general appearance or color-matching of the sign when viewed from a distance of twenty-five (25) feet (7.5 m).

The finished sign shall be clean and free from all burns, sharp edges, loose rivets and aluminum marks.

Signs with any defects or damage that affect their appearance and serviceability will not be acceptable. All metal parts shall be fabricated in a uniform and quality workmanlike manner with all sign surfaces and edges free of defects. No repairs shall be made to the face sheet without the approval of the City inspectors.

ADD the following:
