Seamless heavy-wall tubes and hollow bars

Seamless, hot-rolled heavy-wall tubes are mainly used in mechanical engineering, pipeline construction and steel construction. Our full range covers all common grades dimensions.

Hollow bars for machining have long been a household name in the machining industry. With the introduction of EN 10294-1, the term nominal size has acquired its full meaning. The definition is as follows: The nominal dimension is the guaranteed clean turning dimension for a tube when centred on the outside diameter.
