Trays will be manufactured with a longitudinal ‘T – Welded ‘safety edge along the top wire of the sidewall (excluding 30X50). Trays will be constructed with a 50mm x 100 mm mesh configuration. All tray fittings (e.g. changes in direction, level and size) shall be constructed on site, to the manufactures instruction, using side action bolt croppers and fastened using 25 mm and 30mm counters clamps with M6 bolts and nuts, all surface treated as the tray. Trays will be coupled together using either a fast spring coupler or a 25mm/30mm counter clamp combination with supporting lateral splice plate on trays over 300mm width. The coupling will have the same surface finish as the tray. Trays are to be supplied with cover and suitable cover clips. Trays shell be supported at maximum span of 2.5mm by the trapeze ,wall ,floor or channel mounting methods and will not exceed maximum loads as specified by the manufacturer. The fixture of the cable trays to the supported system shall be fast fixing type bolt free system. Traditional nuts and bolts shall not be used in coupling and fixture of cable baskets to the support systems. Fire test certification should be submitted in accordance with the E30/E90 standard. Loading and deflection characteristic of the tray should be tested and the results published in accordance with the European standard IEC 615357.
