SBM 20/30

SBM Steel Buoys are designed by combining conventional architecture used during several decades with the application of latest technologies in materials and current standards.

The high-quality steel for its construction is the same than the one used in the naval field, with a thickness greater than 10 mm. Float diameters available from 2 to 3 meters are submitted to an antioxidation treatment providing maintenance periods above 5 years. They are characterized by their high shock resistance and stability.

Metallic parts of the buoys (superstructure and tail) are made from hot-dip galvanized steel, and designed to provide a long service life under harsh marine conditions. They can be customized under client’s request, as well as to be made from stainless steel or marine aluminium.
