    Reference projects demonstrate scale, while long-term cooperation demonstrates continuity

     

    A pipe diameter or the number of kilometres illustrates the scale of a project, but the quality of contracting is also reflected in the continuity of client relationships. Warmnet carries out both individual projects and work under annual contracts. Our longest client relationships date back to the 1970s.
