Mesekon is synonymous with welded structures.

We are Mesekon, a turnkey supplier of welded steel structures. We fabricate, machine and assemble steel structures and equipment for industrial processes. Our three decades of experience breed confidence, and investing in continuous development makes for solid expertise.

On land.
At sea.
In the air.
Underground.

Cooperation is based on trust and shared goals.

Mesekon is known as a specialist in process equipment fabrication for the technology industry. We fabricate process equipment for different industry sectors, carry out assembly and machining at our own facilities and actively develop the structure and fabricability of products.

Our special expertise is based on international standard-compliant welding work and a process that provides the customer with the required documentation and traceability. Our production facilities are located in Turku, Finland, but our customers operate globally. Half of our production is shipped directly abroad, and 95 per cent of it indirectly.

Our expertise is scalable between industries, from land to sea, from extreme heat to freezing cold, from underground to high in the sky. Our experience is as broad as the horizon. We have insight into the challenges of the offshore and marine industry and the special needs of the paper and pulp industry and cleantech environments. We are also familiar with the specific requirements of lifting and handling equipment as well as mining and excavation machinery.

We are a seamless joint between the customer’s needs and the equipment.
