Product Overview
The U400 BMC drainage channel is a large-capacity surface water drainage system designed for extensive paved areas and infrastructure projects requiring efficient collection and conveyance of surface water. With a 400 mm inner width, it is suitable for industrial parks, logistics centres, transport hubs and large commercial developments.
Manufactured from fiberglass reinforced BMC composite, this channel combines high mechanical strength with lightweight construction, excellent corrosion resistance and electrical insulation. The non-metallic construction ensures reliable long-term performance without rust or degradation, even in the most demanding outdoor environments.
Key Features
Designed for Large Surface Drainage
The 400 mm inner width provides substantial water collection capacity for projects requiring efficient drainage across large paved areas, including industrial facilities, logistics centres and municipal infrastructure.
Fiberglass Reinforced Composite
Engineered with fiberglass reinforced BMC material, the channel delivers excellent mechanical strength and impact resistance while maintaining a lightweight profile that simplifies installation.
Corrosion Resistant

Frequently Asked Questions
What is the maximum load capacity of the U400 channel?
The U400 system is available with load class ratings up to D400, making it suitable for heavy vehicle access, industrial areas and municipal road applications when fitted with appropriate heavy-duty gratings.
Is the U400 suitable for large industrial facilities?
Yes. The U400 is specifically designed for large-scale applications including industrial parks, logistics centres and commercial facilities where extensive paved areas require efficient surface water drainage.
How does the U400 compare with concrete channels for large projects?
The U400 offers significant advantages over concrete alternatives including lighter weight, easier installation, superior corrosion resistance and elimination of freeze-thaw damage risks. These benefits make it particularly suitable for large infrastructure projects with demanding performance requirements.
