Steel is a popular material in construction due to its strength and versatility. However, when exposed to the corrosive effects of a marine environment, steel is susceptible to corrosion. The primary cause of steel corrosion in the presence of saltwater is rust. The combination of saltwater, moisture, and oxygen triggers a chemical reaction that gradually weakens the steel’s structural integrity.
Newcastle, being a coastal city, is in close proximity to large bodies of saltwater including the Hunter River, Lake Macquarie and of course the Pacific Ocean. This means that certain suburbs face an increased risk of steel corrosion. Suburbs such as Mereweather, Stockton and Newcastle East are particularly vulnerable due to their direct exposure to on shore winds and occasional high humidity.

Selecting the right steel
When working in a marine environment, it is crucial to choose steel that is specifically designed to resist corrosion. Stainless steel and galvanised steel are two popular options.
Protective coatings
Applying protective coatings to steel surfaces is an effective way to prevent direct contact with saltwater and moisture
Proper drainage and ventilation
Proper drainage systems and adequate ventilation help minimise the exposure of steel structures to standing water and excess moisture. Ensuring that water is effectively directed away from steel components and that sufficient airflow if maintained can reduce the risk if corrosion.
Avoiding galvanic corrosion
Galvanic corrosion occurs when two dissimilar metals come into contact in the presence of an electrolyte, such as saltwater. Always use caution when combining different metals, using appropriate insulation or barrier materials to prevent galvanic corrosion. Read more about pairing metals to prevent corrosion here
