Road Projects
Telecom Manhole
Iron covers act as electromagnetic shields and block wireless signals; composite covers allow Radio Frequency transmission with little interference, matching the needs of modern smart municipal infrastructure. No compromise on load ratings or long-term quality.
Sewer Manhole
Vented-hole SMC manhole covers feature preformed ventilation openings. These holes allow continuous gas exchange between the sewer and ambient air. Gases diffuse out slowly to avoid explosive concentrations. In case of deflagration, vents quickly release pressure and reduce the risk of cover ejection.
Stormwater Drainage
In African coastal zones, road and bridge stormwater drainage needs to cope with intense seasonal rain and salt-laden sea spray. Drainage inlets and channels quickly evacuate surface water to avoid standing water and pavement damage. Salt exposure causes fast corrosion, so corrosion-resistant grating and channel systems are selected to safeguard road surfaces and bridge substructures against long-term degradation.
Municipal Projects

Public Utility
School Projects
The utility manhole systems in Asian Schools. Especially China and South Korea, composite cover installation costs are lower than cast iron, with a lighter weight for easy handling and fast fitting. Maintenance expense is minimal, as it resists rust and corrosion, requiring few inspections. However, it has lower load capacity, is unsuitable for heavy vehicle zones, and may age and turn grey slowly under long-term UV exposure. By contrast, cast iron boasts higher strength but suffers from theft risk, heavy lifting labour costs, and recurring rust maintenance fees.
