As an alternate to the hot dip method of ASTM A153, nuts, bolts, washers and other miscellaneous hardwar e, approved by the Engineer, may be mechanically galvanized. The mechanically zinc -coated product(s) shall conform to the applicable coating thickness, adherence and quality requirements of ASTM A153. Mechanically zinc -coated nuts for assembly with mechani cally zinc -coated bolts shall be tapped oversize prior to coating and need not be re -tapped afterwards.
C.Type III. ASTM A123 Zinc (Hot -Dip Galvanized) Coating on Iron and Steel Products, except as modified herein. A minimum weight of coating ( oz/ft2 of surface) for base metal less than 1/16 inch thickness shall be as follows: Average of Specimen Any Individual Specimen or Computed Value 1.5 1.25

1.Preparation of Base. Those areas to be coated shall be sand blasted with silica sand or crushed garnet of such gradation that sand shall be mesh size 20 to 40 with a minimum of 40% retained on a No. 30 mesh screen (U.S. Standard Sieve series). Pressure of not less than 75 psi shall be maintained at the blast generator. A sample steel plate shall be blaste d until the surface cannot be further cleaned or roughened. This plate shall be used for visual comparison and any areas that do not meet this standard as to roughness or cleanliness shall be reblasted.
2.Zinc Application. The wire used in spraying shal l be 15 ga., 1/8 inch or 3/16 inch diameter, zinc 99.0% purity. Air pressure at the Air Control Unit shall be 60 psi and there shall be no more than 35 feet of 3/8 inch I.D. hose between the Air Control Unit and the gun. The metal coating shall be applied at a minimum thickness of 3 mils . At least one coating shall be applied within 4 hours of blasting and the surface must be completely coated within 8 hours of blasting. The specified thickness of coating shall be applied in multiple layers and in no case shall less than two passes be made over every part of the surface.
3.Finish Coat. The zinc coating shall be given a finish coating consisting of two coats of Aluminum Vinyl sealer. This sealer shall consist of a volatile vehicle containing a minimum of 20% Vinyl Copolymer and plasticizer and a minimum of 10% Non -Leafing Aluminum Flake. REPAIR. The Contractor shall be required to repair damaged areas of galvanized zinc coating. Damage may result from wet storage (white rust), welding or cutting (flame), or from excessive rough handling during shipping or erection. In general, only field repairs will be allowed. Shop repairs shall only be permitted when the total area of damage on any single piece is less than 2% of the coated surface or 16 square inches , whichever is less. Any coated piece on which the total area of damage exceeds these amount s in the shop shall be rejected. Materials for field repair shall be selected from Department =s Approved List of Galvanized Repair Materials. Zinc solders shall be zinc -cadmium and zinc -tin-lead alloys supplied in stick or paste form,
719-02 Aluminum Anodic Coatings
NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 700 STANDARD SPECIFICATIONS (USC) May 1, 202 4 VOLUME 4 and that liquidize for application at temperature ranges of from 518 to 527OF and 446 to 500OF, respectively. Zin c paints shall contain not less than 65% zinc dust (by weight) in the dried paint film and shall meet current standards for the emission of volatile organic compounds. Detailed requirements for the approval of galvanized repair materials are available fro m the Materials Bureau. Corrosion deposits shall be removed in a manner satisfactory to the Department prior to incorporation of the material in the work. After removal of these deposits, the coating shall have a uniform appearance free from uncoated spots , lumps, blisters, gritty areas, acid, flux and black spots. Materials with these defects will be rejected and shall be immediately removed from the worksite. Acceptable material shall be provided to replace rejected material at no additional expense to th e State. Damaged areas of loose and deteriorated galvanized zinc coating shall be cleaned by power sanding, power grinding, or abrasive blast cleaning to bright metal. If zinc solder is used for repairs the cleaned area shall be preheated in accordance w ith the manufacturers instructions for use. The heated surface shall then be rubbed with a repair stick to evenly distribute a layer of zinc alloy, or if zinc paste is used it shall be spread evenly using a spatula or similar tool. Zinc solder shall be d eposited in a uniform layer at a minimum dry film thickness of 3 mils . If zinc paint is used for repairs it shall be applied in accordance with the manufacturers instructions for use, using a brush or by spray methods. Zinc paint shall be applied in su ch quantity as to produce a minimum dry film thickness of 3 mils . BASIS OF ACCEPTANCE. The acceptance of galvanized coating and repairs is included in the acceptance of the materials receiving the coating.
