Founded in 1952 by A. van der Velde as a non-ferro foundry, Winteb has grown into the world's largest producer of seawater resistant aluminium (DIN1725) Air Pipe Heads. Winteb has been producing these Air Pipe Heads since 1985, starting with the WIKO5000 series. In the year 2000 Winteb developed the WIN2000 air pipe head series which set the standard in air venting. This series is also produced out of seawater resistant aluminium. Furthermore the WIN2000 series has a space and weight saving design that is revolutionary compared to other Air Pipe Heads.
