Common use of Galvanizing Clause in Contracts

Galvanizing. Galvanizing shall be applied by the hot dipped process. The preparation for galvanizing and the galvanizing process shall not adversely affect the mechanical properties of the material being coated. The zinc coating shall be clean, of uniform thickness and free from defects. When zinc spray coating is used, surfaces shall be shot blasted before spraying. Drilling, punching, cutting, bending and removal of burrs shall be completed before galvanizing/zinc spray coating. The average thickness of the zinc coating shall be equivalent to not less than 0.6 kg/m2 of zinc for all surfaces, except steel wires. The thickness of the zinc coating for steel wires shall be in accordance with a national standard and shall be approved by the Engineer. Material on which galvanizing has been damaged shall be re-dipped unless, in the opinion of the Engineer, the damage is local and can be repaired by applying a coat of galvanizing repair paint. Where such a repair is authorized, tdamaged area shall be cleaned bwiping with clean rags saturated with mineral spirits or xylene followed by wire brushing. After wire brushing, the area shall be re-cleaned with solvent to remove residue and shall be given a minimum of two coats of zinc rich paint in accordance with the manufacturer’s instructions. Samples selected by the Engineer of all galvanized material shall be subjected to the galvanizing tests set out in the appropriate material standard (eg BS 443/BS 729). Sheradizing or other similar processes shall not be used unless expressly approved by the Engineer. Surfaces in contact with oil shall not be galvanized or cadmium plated.

Galvanizing. Galvanizing shall be applied by the hot dipped dip process. The preparation for galvanizing and the galvanizing process shall not adversely affect the mechanical properties of the material being coated. The zinc coating All galvanising shall be cleanin accordance with EN ISO 1461:1999 or an equivalent approved standard to give a uniform thickness, of uniform thickness and free from defects. When zinc spray defects and a minimum average coating is used, surfaces shall be shot blasted before sprayingweight. Drilling, punching, cutting, bending and removal of burrs shall be completed before galvanizing/. For zinc spray coating, surfaces shall be shot blasted before spraying. The average thickness of the zinc coating shall not be less than 505 g/m2 (equivalent to not less than 0.6 kg/m2 70 microns) of zinc for all surfaces, except surfaces of steel wires. The of thickness of the zinc coating for steel wires shall be in accordance with a national standard and shall be approved by the Engineer 3mm to  6mm. Material on which galvanizing has been damaged shall be re-dipped unless, in the opinion of the Engineer, the damage is local and can be repaired by applying a coat of galvanizing repair paint. Where such a repair is authorizedauthorised, tdamaged the damaged area shall be cleaned bwiping by wiping with clean rags saturated with mineral spirits or xylene followed by wire brushing. After wire brushing, the area shall be re-cleaned recleaned with solvent to remove residue and shall be given a minimum of two coats of zinc rich paint in accordance with the manufacturer’s 's instructions.
