SIGN SUPPORT STRUCTURES (a) General Sign support structures shall be fabricated from steel sections which shall comply with Standards the requirements of AS 1163, AS 3678 and AS 3679.1. Signs support structures shall be standard round galvanised posts of 50, 65 or 80 mm Size nominal bore or purposedesigned steel structures as shown on the Drawings and manufactured in accordance with the requirements of AS . Splices in members shall be restricted to a maximum of one splice per member. Splices Splices shall be full penetration butt welds. All welding shall be as shown on the Drawings and in accordance with the requirements Welding of AS 1554.1, Category GP. Standard (b) Protective Treatment Except for standard galvanised posts, all steel components including brackets shall be Hot-Dip protected by hotdip galvanising after all fabrication processes are Galvanising completed. The steel components shall be finished by the hotdip galvanising process in accordance Finish with to provide a minimum thickness of 100 microns and a bright finished surface free from white rust and stains. Bolts, nuts and washers and brackets shall be galvanised in accordance with AS 1214. Bolts, Nuts etc. Splices in standard galvanised posts shall be painted by using a zincrich to provide a Splices zincrich coating at least equal to the thickness specified for the galvanised layer. Scratched and slightly damaged surfaces of galvanised coatings shall be renovated by Damaged using a zincrich to provide a zincrich coating at least equal to the thickness Surfaces specified for the galvanised layer. This method of renovation shall be restricted to areas not exceeding 2500 square millimetres on any one structure. Any structure with totallydamaged coating areas exceeding 2500 square millimetres shall be regalvanised by the Contractor. (c) Attachment of Signs Posts and other components shall be provided with the required sign attachment holes or Typical fittings to suit the typical attachment systems as shown on the Drawings. Systems Sign panels shall be attached to each supporting member at each extrusion section or bolthole in the sign panel. ERECTION OF NEW SIGNS SETTING OUT
