Marconn and the Use of Polyethylene in Port Infrastructure

Real resistance to salinity, impact, and solar radiation in demanding marine environments

In the marine environment, there are no compromises. Salinity, UV radiation, constant humidity, and mechanical impacts put every material to the test. If we observe which elements remain intact for years in the ocean — buoys, floating pontoons, fenders, or auxiliary structures — we find a common denominator: high-density polyethylene (HDPE).

Following this same logic, Marconn manufactures the casings of its pedestals in polyethylene. This is not an aesthetic or circumstantial choice, but a technical decision based on experience and on the proven performance of the material under extreme conditions.

Polyethylene does not rust, does not corrode, and is not affected by salinity. In addition, it offers high impact resistance, stability against solar radiation, and excellent performance under sudden temperature changes. This allows the pedestals to maintain their structural integrity and exterior finish even after years of direct exposure to the sea.

The result is a solution designed for intensive use in marinas and yacht harbours, combining robustness, low maintenance, and an innovative aesthetic adapted to the marine environment.
Confidence in the material translates into a firm commitment: a 20-year warranty on the casing, reflecting a clear commitment to quality, durability, and long-term reliability.
