Modern urban and landscape construction requires drainage systems that balance durability, corrosion resistance, load capacity and cost efficiency. Our PP or Plastic linear drainage channels paired with B125 to D400 grade ductile iron covers deliver a highly reliable, versatile and long-lasting drainage solution for commercial, municipal and traffic areas.

Made of high-strength modified PP material, the channel body features excellent anti-corrosion, anti-aging and anti-UV performance. Unlike concrete and metal channels, Plastic drainage channels will never rust or degrade under long-term exposure to rainwater, chemicals and temperature changes. The smooth inner wall ensures fast water flow, effectively avoids blockage, and greatly reduces daily maintenance costs. With a unified structural design for each inner width specification, only the height varies, ensuring easy installation, perfect alignment and stable quality in mass projects.

Matched with professional ductile iron covers covering full load classes from B125, C250 to D400, the system meets different traffic and site requirements. B125 is ideal for pedestrian areas, plazas and garden landscapes; C250 suits parking lots and light vehicle passages; D400 is applicable for roads, driveway entrances and heavy-load traffic zones. All iron covers are precision cast, anti-settling, anti-noise and pressure-resistant, fully adapting to frequent vehicle rolling and harsh outdoor environments.

The combination of lightweight corrosion-resistant PP channels and high-load iron covers achieves an optimal balance between hydraulic performance, structural strength and service life. Our PP Trench channels and Cast Iron Gratings have passed strict tests and obtained CE certification, and are widely exported worldwide. It is a cost-effective and standard drainage system for sponge city construction, municipal engineering, commercial projects and residential landscapes.
