Products Description
This prefabricated polymer concrete drainage channel is equipped with a heavy-duty ductile iron slotted grate. Made of high-density polymer concrete, it features high compressive strength, low water absorption, excellent corrosion resistance and long service life. The U-shaped inner cavity optimizes water flow capacity for rapid rainwater discharge. Widely adopted in municipal works, roads, plazas, parking lots and landscape projects.
Key Features
High Strength & Anti-Corrosion
Polymer concrete body resists acid, alkali, salt and freeze-thaw damage, suitable for harsh outdoor environments.
Efficient Drainage
U-shaped cross-section delivers superior hydraulic performance, quickly removes surface water and prevents waterlogging.
Heavy-Duty Ductile Iron Grate
Slotted cast iron cover bears vehicle loads; anti-slip surface increases safety for pedestrians and traffic.
Lightweight & Easy Installation
ighter than traditional concrete channels, simple assembly, shortens on-site construction time.
Application Scenarios
- Municipal road drainage, urban rainwater collection systems
- Commercial parking lots, shopping plazas
- Residential districts, parks, walkways and landscape projects
- Airport, ports, industrial zones and highway auxiliary drainage
