Despite the advance of electronic satellite navigation, physical signaling through lighthouses remains essential for plotting geographical positions. In the upper dome of these towers, known as the lantern, the constant atmospheric aggression of the marine environment requires materials with maximum durability. The main challenge in these historical infrastructures consists of replacing traditional metals to prevent continuous deterioration from corrosion and reduce high maintenance costs.

For the 19-meter lighthouse erected on Clover Island, a composite concrete structure was executed, topped by a 3-meter lantern fabricated entirely from stainless steel. The dome houses a solar lamp programmed to flash every four seconds, offering uninterrupted visual guidance. This integration between the concrete body and the metallic dome ensures optimal interaction with harsh coastal conditions.

Performance and Properties
Exceptional resistance to corrosion through the use of type 304, ensuring prolonged structural performance without degradation.

Design and Finishes
High-visibility structure that interacts with natural light and weathering, preserving its aesthetic quality and metallic finish.

Direct Applications
3-meter-high dome lantern and structural plates of varying thicknesses totaling over 15 tons of material.

Life Cycle
Enhanced long service life with minimal maintenance cost, ideal for isolated public infrastructure.
