ACO - Highway and Motorway Grated Trench Drains, Access Covers and Cable Pits

As an ISO 9001-registered company, ACO has supplied a variety of products, including access covers, cable pits and grated trench drains, to highways and motorways worldwide for over 30 years.

Road drainage systems, electrical pits and manhole covers

Highways and motorways provide the most challenging environments for drainage systems, electrical pits and manhole covers. A variety of vehicle types, from cars to semi trailers, can impose severe stress on road surfaces by travelling at high speeds, and breaking and turning in various weather conditions, 24 hours a day.

Only proven, reliable, quality products are used in these applications. Drainage systems need to work efficiently to ensure surface water is removed quickly and that accidents caused by aquaplaning do not occur.

Highway grated-trench drainage systems

ACO's grated-trench drainage systems (ACO DRAIN) are available in many configurations and sizes to allow for the efficient removal of surface liquids from roads. The trench comprises interlocking precast channels made from polymer concrete, a durable resin composite with excellent strength properties.

ACO's grated-trench systems are either monolithic in construction for optimum safety in high-speed traffic or are available with removable grates that are locked with boltless mechanisms into integrally cast ductile-iron edge rails with anti-shunt mechanisms.

Interlocking precast drainage kerbs

Monolithic interlocking precast drainage kerbs (KerbDrain™) are available for use with our grated-trench drainage systems, to reduce the width of flow where there is limited space between the edge of the carriageway and the kerb.

Road cable pits and surface ducting systems

A range of cable pits and surface ducting systems (ACO CABLEMATE) is also available for road applications. ACO was the first approved registered supplier of pit covers to Queensland Main Roads. The covers are part of a dedicated range of products for this niche market.

ACO's upgraded range complies with Main Roads' specification and is manufactured to Main Roads' standard drawings. All lids are tested to AS3996-2006 and have an electrical insulation coating that meets the AS/NZS1580.408.5-2006 standard.

Highway manhole covers and frames

ACO ACCESS is Australasia's widest and most comprehensive range of manhole cover and frame solutions in a choice of materials including ductile iron, galvanised steel and composite plastic. These systems are available in all sizes and multipart configurations. The range complies with the industry's strictest regulatory requirements.
