Gizom is very well known for its concentric aluminium reducers. We make these (welding)fittings available in various alloys and sizes, both for metric connections and inches according to ANSI. In addition to the concentric reducers, Gizom also has excellent contacts for eccentric reducers.

In addition to supplying individual products, we are also able to supply everything as a prefabrication, so that it can be applied directly in the desired setting. Some operations we can perform there in are welding and surface treatments.
