EFFECT OF SUNLIGHT
Exposure to stong sunlight over a period of months will result in a gradual loss of strength in black coloured Autoway Fabrics.  It is advisable not to remove the wrapping until the fabric is required for use
EFFECT OF TEMPERATURE
Fabric strength is unaffected between a temperature of -25ºC / +100ºC
FABRIC LENGTH
Standard length of 100 metres rolled on to a robust cardboard tube.  Longer lengths available on request
FABRIC WIDTH
Standard 4.5 metres.  Other widths can be made to order.
