The Althon Lid Unit Range has been put together to cater for all site circumstances. We provide lids for our high capacity channel drainage suitable for use in areas of tarmac, concrete hard-standing and block paving. The Stilpro lid unit comes complete with a 6mm slotted stiletto heelproof D400 load class ductile iron grating, making it the most aesthetically pleasing high capacity drainage system available. Our Forma and XHB systems are ideal for use in industrial estates, service yards, container terminals and rail depots. Please use our Lid Selector function to help you choose the best lid for you.
