METAR TRAY
METAR TRAY
Recommended number of
fixings of cable tray fittings
All METAR cable tray fittings are available to order with
radii of 300mm, 450mm & 600mm. Those cable tray
fittings which have a standard radius of 75mm are also
available to order with a radius of 150mm. Consult our
Sales Team for details.
Material Gauges
The standard range of material gauges for the METAR
cable tray & fittings have been determined by providing
the most cost effective and efficient gauge for each
material type to suit the designed application of each of
METAR cable tray system types.
The standard material gauges are supplied for each tray
and fitting type & width unless otherwise specified. To
order a non-standard gauge, suffix the part number with
the required gauge in millimeters.
Consult our Design Team for guidance on the appropriate
selection of non-standard material gauge combinations.
Weights, where quoted in the catalogue, are for the
standard gauge mild steel/hot dip galvanized item. The
following correction factor should be used to determine
the weight for the corresponding item in an alternative
gauge and finish.
METAR cable tray fittings have integral jointing strips
for connecting to straight lengths and for connecting
cable tray fittings to cable tray fittings. The cable tray
fixing set comprises of an M6 x 12 screw and an M6 nut
(plus an M6 flat washer for stainless steel fixings).

The following table shows the standard material gauges
for each width and type of METAR cable tray system in
a number of finishes. Consult our Design Team for gauge
details for other materials & finishes.
As an example:
A heavy duty return flange cable 900flat bend, 600mm
wide, hot dip galvanized finish in standard 2.0mm gauge
weights 9.56kg. Equivalent weight of the stainless steel
item in 2.0mm gauge = 9.56kg x 0.96 = 9.18kg.
