MetroDuct Twinwall Ducting

Civils, utility and telecommunications projects all have one thing in common, they use ducting to protect cables and pipework that bring power, communications and water to many essential applications.

Ducting comes in a variety of colours and markings to distinguish one utility from another.  This is particularly useful when it comes to identifying the correct ducting when it comes to future repairs and maintenance work.

George Lines supplies ducting in the full range of colours and markings to suit NJUG recommendations. Our range of MetroDuct offers all the advantages of a lightweight flexible ducting product, with unrivalled strength and durability.

Designed to meet current compression strength Highways specification, our MetroDuct Twinwall ducting is fully compliant to the new BBA certification for sealed systems. This incorporates all ducting sizes ranging from 63mm to 173mm.

Key Benefits of MetroDuct

Manufactured in polyethylene and issued as standard in 6 metre lengths or 50 metre coils, the corrugated exterior of these ducting pipes deliver additional strength. Whilst the internal surface has an extremely smooth bore to prevent cables from snagging.

Other advantages include:

  • Easy installation thanks to push fit joints
  • HDPE flexibility to reduce the need for bends and to cope with trench undulations
  • Extreme compression strength
  • Water resistance when sealed
  • Ability to be laid at extreme temperatures
  • High chemical resistance
  • High impact resistance to minimise special preparation of beds and eliminate the need for special surrounds (in most instances)

Our full ducting range is available to order at all Lords branches. Collection is available from Hayes & Colnbrook.  For more details or to place an order please call George Lines on 01753 685354.
