We pay particular attention to renewable energy sector, which represents the future of the world's power generation. The excellence of our steel tubes for solar collectors highlights our core values and philosophy. CSM Tube constantly invests in equipment, research and skills for renewable sector.
For example, we can manufacture all kinds of coiled tubes for heat exchange to equip solar heating systems. We are also equipped to manufacture collectors for heating coils as well as headers and connections making it easy to create heating networks for domestic and commercial use.
We produce solar collector’s steel tubes in line with highest international standards. The renewable energy sector requires products which resist corrosion and offers extended durability, perfectly represented in our connectors, headers and coils. They will become a reliable part of any organization’s sustainable energy strategy.
Our stainless steel tubing for solar collectors comes in coiled and bar formats featuring various thicknesses and diameters. High nickel and AISI alloys can be used along with heat treatment to ensure extra durability.
