For high volume catchment areas with restricted depth and extra heavy duty traffic loads, CH300 drainage channels are the answer.
Orca Drain CH300 series is manufactured from corrosion resistant polymer concrete with integrated ductile iron edge rails. Orca polymer concrete is non flammable, frost proof and resistant to weathering and diluted acids and alkali’s.
Orca Drain CH300 grates lead the industry in design and quality. CH300 channel grates are held captive in the edge rail and are engineered to meet the following standards:
AS3996:2006 Access covers and grates
AS4586:2013 Slip resistance classification of new pedestrian surfaces
