MM RAILduct™

MM RAILduct™ Cable Trough (2)
MM RAILduct™ Cable Trough

MM RAILduct™ is an GRP moulded cable trough system. Weighing under 10kg but capable of of taking loads imparted by vehicular traffic, MM RAILduct™ offers significant advantages in health and safety, speed of installation and flexibility.

Most importantly, laying MM RAILduct™ is typically 5 times faster than traditional concrete units, reducing the total cost of installation.

1 metre long sections are connected together using jointing pegs which allows 1-3° of movement possible to follow gentle curves in the track.

MM RAILduct™ has been installed in many rail applications throughout the world and in different extremes of temperatures. It has also been adapted for projects in power and highways applications and is type approved for use in TfNSW (Transport for NSW) networks.

MM Railduct™  is commonly used for the following applications:


  • Telecommunications 
  • High / Low Voltage power cabling 

Power & Energy

  • High / Low Voltage power cabling 


MM RAILduct™ a is manufactured in Sheet Moulding Compound (SMC), a form of Glass Reinforced Polyester Resin (GRP).

Benefits of GRP:

  • High strength to weight ratio
    The material is significantly lighter than other conventional materials that can provide the same inherent strength.
  • High temperature range
    GRP is a thermoset material, meaning that it irreversibly cures when heated. As a result, GRP will not melt, drip or form molten droplets.
  • Fire retardancy
    MM RAILduct™ won't catch fire and has low smoke properties. This means the product can be used in enclosed areas such as tunnels and underground transport.
  • High mechanical properties
    The material is non-conductive, has a low coefficient of expansion and is resistant to weathering. GRP possess high tensile and bending strengths combined with high stiffness. The material is superior in mechanical strength properties compared to those of commodity thermoplastics such as the Polypropylene and the Polyethylene family.
  • Chemical resistance
    GRP is chemically inert, which means it is not chemically reactive. Its high chemical resistant nature is essential for ensuring a long service life when buried underground. GRP is not affected by frost, acids, alkalis or diesel, all of which will affect the lifespan of concrete products.
  • Not susceptible to creep
    Creep is the tendency of a solid material to permanently deform under continuous or long term loading or mechanical stresses.
