Celebrating 40 years of aerospace service and experience, integrating the knowledge and success of our team from our Issoudun, France facility across the global Mannesmann facilities to bring our aerospace & defence customers a truly versatile product offering. 

Innovating to set tomorrow’s standards for lighter, stronger materials – operating under higher pressures to meet and exceed exacting performance expectations.  

Bringing together our manufacturing facilities in Germany, France, Italy and USA whilst embracing and developing our manufacturing relationship in India. 

Recognizing the needs of our customers for quality, cost competitiveness and service. 

Service & Flexibility

Rapid deliveries, supporting breakdown requirements from our EU and US production facilities. 

Utilising the flexibility of its Issoudun, France and Houston, USA production facilities MST has launched a new service offering a manufacturing lead time of 6 weeks, to support rapid delivery needs on breakdown requirements.

Engine fuel systems, air bleed, heat exchangers and hydraulic controls.

Austenitic, martensitic PH grades and nickel superalloys (Ni-Cr, Ni-Co) for high temperature creep and oxidation resistance.
Supplied as straight tubes, components or profiles.
