Channel Drain Load Classes — A15 to F900
Load classifications define the maximum test load a drainage channel system has been assessed for under EN 1433. Selecting the correct class for your application is essential — an under-rated channel may fail under load. Final suitability always requires confirmation against product documentation and project conditions.

Pedestrian & Landscaped Areas
A15 is a documented load classification under EN 1433, generally considered appropriate for pedestrian and landscaped areas. Final suitability depends on specific site conditions, installation detail and the manufacturer's technical requirements.
Typical applications
- •Patios
- •Garden paths
- •Pedestrian walkways
- •Landscaped areas with no vehicle access
Requires further assessment
- —Any area where vehicles will cross or park over the channel
- —Driveways with vehicle access
Available materials
Polypropylene, Polymer concrete
Available grate types
Polypropylene, Galvanised steel, Aluminium
View A15 productsDriveway & Light Vehicle Areas
B125 is a documented load classification under EN 1433, commonly considered for suitable driveway and light-vehicle applications. Final suitability depends on traffic position, installation detail and the manufacturer's technical requirements.
Typical applications
- •Residential driveways
- •Domestic car parks
- •Light vehicle areas
Requires further assessment
- —Commercial vehicle routes
- —HGV access roads
- —Areas with frequent heavy vehicle crossing
Available materials
Polypropylene, Polymer concrete
Available grate types
Ductile iron — slotted, Ductile iron — heelguard, Polypropylene — heelguard
View B125 productsCommercial & Kerbside
C250 is a documented load classification under EN 1433, generally associated with commercial car parks and kerbside areas. Final suitability depends on project-specific loading conditions, installation specification and the manufacturer's technical requirements.
Typical applications
- •Commercial car parks
- •Kerbside drainage
- •Appropriate medium commercial areas
Requires further assessment
- —Major road applications
- —Continuous HGV traffic areas
- —Industrial vehicle routes
Available materials
Polymer concrete
Available grate types
Ductile iron — wide slotted, Galvanised steel — top slot

D400 is a documented load classification under EN 1433, commonly used for road drainage and heavy-vehicle areas. Final suitability requires confirmation against project-specific loading, installation and manufacturer documentation.
Typical applications
- •Roads
- •Heavy vehicle access routes
- •Industrial access roads
- •Urban drainage
Requires further assessment
- —Extreme industrial loading without verification
- —Aircraft or port areas
Extreme Duty
F900 is the highest documented load classification under EN 1433, associated with extreme-duty environments including aircraft stands, ports and heavy industrial sites. Project-specific assessment is required before specifying F900 products.
Typical applications
- •Aircraft stands
- •Dock areas
- •Port environments
- •Extreme industrial loading sites
Requires further assessment
- —General commercial or road use — lower-rated channels are normally appropriate
