Solutions for critical offshore components

Columbia Metals is an approved supplier to major subcontractors in the global oil and gas industry. Our materials are used in downhole tooling, valves components and assemblies and we have established ourselves as a high quality and reliable supply partner in this sector.

Our alloys for the oil & gas industry feature excellent heat and corrosion resistance. We hold extensive stocks of nickel-based alloys as well as duplex and superduplex stainless steel. This product range is enhanced by our trademark alloys, especially NIBRON SPECIAL®, which is widely specified by leading OEMs for use in all types of critical subsea components in aggressive offshore environments.

Through our partnership with European forges we can also offer bespoke forged rings, blocks and shafts made from nickel alloys and many grades of steel.
