1) Polymeric concrete is a durable channel with high strength and chemical resistance. It is long lasting and has no hazard to environment, so can widely used for drainage systems.
2) All our channels are made of polymer concrete, 1000mm long and the CO (internal width) is from 100mm to 400mm with variety external height. About the grating material we usually use Ductile Cast Iron,Stainless Steel and Galvanized Steel.
