Tubes with high corrosion resistance

Tubos zincados y pintados con poliéster

Tubes with high corrosion resistance for environments like offshore wind energy galvanized and painted with polyester paint with high mechanical strength and to ultraviolet rays.

The tubes without welding galvanized and painted with polyester paint, are particularly suitable for hydraulic and pneumatic applications requiring high resistance to environmental corrosion.

Besides zinc, the additional layer of polyester paint gives the tube a high mechanical strength (erosion, etc.) and ultraviolet rays at a facility located outdoors.

The results obtained in testing in salt spray chamber the curved excess of 1000 hours without appearance of white rust (zinc):
