Who are we ?

CSM NV, with branches in Achel and Hamont, was established in 1964 and has since grown to be one of the most important companies in the area of engineering, manufacturing, preservation and erection of steel constructions.


With the performance of our projects, we consider the quality of the products, respecting of the planning, safety during the execution and outstanding contact with the client, central.


C.S.M. NV designs, manufactures and installs various types of steel construction and caters to a widespread international market. The contractual specifications for the construction are mostly recorded by the client and are based on specific (inter)national standards. In addition to high quality requirements, this also involves a large extent of flexibility with regard to the specific method statement.

It is CSM’s ambition to maintain its reputation as a high-quality company while simultaneously optimising its profitability.

Client at the forefront

In the quality policy of CSM the client takes centre stage, right from the tender request through to the final release of the construction; CSM makes every effort to deliver projects in accordance with the requirements and demands of the client, on a technical level, while taking into account the specific safety and environmental requirements and in keeping with the agreed schedule.

Always better

CSM also strives towards continuous good management of the quality of its organisation and method statements and therefore also the quality of its products and services, and where possible to improve upon and in so doing, take into account – and to keep watch over - the safety of its personnel and the environmental aspects.
