Features & Benefits
- Composite PE and Steel Construction
Combines the corrosion resistance and flexibility of polyethylene with the structural strength of steel, delivering exceptional long-term performance. - Mechanical Composite Assembly
The PE layers and steel reinforcement are mechanically assembled without the use of chemical adhesives or bonding agents, ensuring a robust and durable composite structure. - Extensive Diameter Range
Available in sizes from 800 mm to 2000 mm, making the system suitable for a broad range of large-scale sewerage and drainage projects. - Smooth Internal Bore
The smooth PE inner surface promotes efficient water flow, reducing hydraulic resistance and minimising sediment build-up. - Smooth External Surface
The flat external profile simplifies handling and installation while providing durable protection against environmental conditions. - Reliable Jointing Options
Available with integrated electrofusion socket connections or gasketed joint systems, providing secure, watertight and dependable connections. - High Joint Integrity
Designed to deliver long-term sealing performance, reducing the risk of infiltration and exfiltration throughout the pipeline’s service life. - Lightweight Design
Significantly lighter than traditional rigid pipe materials, enabling easier transportation, handling and installation while reducing construction costs. - Excellent Chemical and Abrasion Resistance
HDPE construction provides outstanding resistance to corrosion, chemicals and abrasive media, ensuring long-term durability in demanding environments. - Electrically Non-Conductive
Inert to stray electrical currents, helping to prevent corrosion-related issues commonly associated with metallic pipeline systems. - Ideal for Underground Infrastructure
Suitable for gravity sewerage systems, drainage networks, road embankment crossings and a wide range of non-pressurised civil engineering applications.
