Providing, installing and fixing with necessary clamps etc. retro-reflective Single Sided gantry/overhead and cantilever mounted signboards comprising of customized modular PU Epoxy coated MS tube, frame work, aluminum composite panel (ACP) both side , digitally printed micro prismatic retro-reflective sheet signages with QR Codes. (i) The horizontal and vertical members of the MS frame module shall be made of MS tube 50x50x4.50mm thick as per approved drawing and each panel shall be braced diagonally (one way only) with same section. (ii) The aluminum composite panel (ACP) both side shall have thickness of 4mm consisting of 3mm thick Non FR grade thermoplastic core of LDPE/HDPE sandwiched between two 0.50 Aluminum sheets. The ACP Sheet shall be coil coated with kynor 500 base PVDF on one face and another face will be mill finish for pasting retro reflective sheet. The ACP shall be routed, folded and fixed on the MS frame with VBH tape, 24mm wide and 0.5 mm thick of approved brand & made provided throughout the length and breadth of the frame including riveting at the right angle face of the frame with pop riveting or with self taping SS screws 5mm dia spaced not more than 300mm center to center on both side of frame ensuring that no riveting is seen on either face of the frame. (iii) On the front face of the ACP, micro prismatic retro reflective sheet conforming to Type-XI of IRC 67-2022 and ASTM:D4956-17 with digitally printed signs on top of the base retro reflective sheeting covering the entire sign facia (end to end) shall be pressure fixed. The sign shall be manufactured using a system of matched components of reflective sheeting and overlay films and digital inks manufacuted and supplied by the reflective sheeting manufacturer. The digital printer and digital ink shall be approved by the reflective sheeting manufacture. Digitally printed traffic colour (which ever required) areas on white sheeting shall not be having less than 70 percent of the value of the coefficient of retro reflective established for its colour and type of sheeting. (iv) The rear side of the MS frame shall be covered with balancing ACP sheet of the same description as mentioned above and shall be fixed in similar manner as described above. The edges of the board shall be covered alround with 50 micron powder coated die cast extruded aluminum channel of required color and shade of size 68x12x2mm. the channel shall be fixed using two rows of double sided VHB tape of above description. The channel shall further be secured by pop riviets having SS screws of 5mm dia at junctions and corners. (v) Labes/QR Code to be printed on signage at bottom right side corner (2”x2”) with details like name of manufacture, date of manufacturing, code of reflective sheeting used, warranty etc. Note: The rate shall include all materials, labour, equipments, fabrication transportation, erection, installation and incidentals all complete as per direction of Engineer-in-Charge. Only front area of the board shall be measured for payment i.e. only one side shall be measured for payment.
