Purchase channel stones and customize to measure

The robust stones are finally made to measure on precise processing machines. The custom-fit gutter stones are completely pre-assembled before delivery in order to be able to check all dimensions of the already existing sewer in advance. With the assembly on the corresponding sewers nothing stands in the way of the frictionless drainage of liquids. No matter in which dimensions (length, width, height) the blocks are to be made – they represent the custom-made solution for the glass industry in every design!

Contact us online or by phone and provide us with the required dimensions (length, width, height). In cooperation with our premium manufacturer Parkinson-Spencer Refractories Ltd. (PSR) we manufacture and deliver the drainage blocks within shortest time. Convince yourself now of our quality products for the glass industry!
