Pile cages


Our welding department at the Dormagen branch, which has been in existence since 1991, has been constantly upgraded and expanded so that we can produce an average of 1,400 t of round pile cages per month. Our storage area of 15,000m² also allows us to handle large projects with ease. Deliveries are made using our own trucks, up to 24m in length as well as with self-loading crane vehicles.
