What if your components supplier could also deliver solutions?


At Marmen, we have developed exceptional expertise in the welding and assembly of all types of alloy steel, nickel alloys and corrosion resistant coatings (e.g. Inconel and stainless steel).

Eager to meet your needs perfectly, we strictly respect the submitted plans and technical specifications. With our solid expertise, we ensure impeccable quality at competitive prices.


State-of-the-art facilities

The exceptional capacity of our facilities allows us to manufacture both small and non-standard parts as well as steel structures of extraordinary height.

Our fabrication processes are optimized by our automated equipment. Our facilities include a wide range of state-of-the-art automated equipment (manipulators, positioners and robotic cells) that allow us to have no limits on the complexity of the parts we manufacture. We also use manual welding for some parts that require greater dexterity or are difficult to access with robots.
