| 1 | Supplying and Fixing 22 mm thick Polycarbonate sheet roofing canopy: Design, Manufacture and Installation of roofing system, a complete assembly of extruded cellular structure multi cell/ multi layered UV protected polycarbonate panels Cellular structure system. Co-extruded UV protected polycarbonate panel system of minimum 22 mm thickness to ensure best performance for wind uplift and visual appearance. Panels shall be manufactured with vertical offset standing seam at both sides of the panel. Panels shall be of anti-reflective / softlite / antiglare type to prevent glare. The width of the panels shall be minimum 900 mm-1220 mm and panels with maximum width shall be preferred to minimize junctions and to ensure a leak proof system. Panels shall have minimum five to seven layers for better strength with truss bracing cell structure. Panels shall be fixed on Purlins with expansion fastener with three numbers of self-drilling screws to ensure pull out load of minimium 7000 N (7KN) tested as per ISO 6892:1998 &IS 1608:2005 (design load 250 kg/clip) / Aluminum spacers and connected with polycarbonate U connectors to interlock the panels with snap on / click-on / grip lock mechanism to ensure maximum uplift capacity. Panels will be sealed with mill finished aluminium U profiles at the ends. Each panel shall be with opaque and clear combination of louvers inside the single panel i.e. with transparent body and opaque layers in between layers for better ambience and increase shading and variable daylight and minimising direct sunlight in the noon. Polycarbonate panels also shall have Yellowness Index as per ASTM D 1925 when tested on a sample exposed to UV for 500 Hours as per ASTM G 155. The polycarbonate panels must satisfy Dart drop impact test as per IS 14443-97 shall show no sign of breakage on Polycarbonate sheets which have been exposed to UV for a min. of 500 Hours as per ASTM G 155. The panels shall be fixed over structural steel / MS purlins and be secured with Snap- On connectors at all levels including all accessories like screws, trims etc. complete to make a water tight roofing canopy conforming to specifications and directions of Engineer-in-Charge.
