During a construction project, a wise builder knows that we don’t only look at the building materials we’re using, but also the environment of where they will be used. Our materials will react and be altered by fluctuations in temperature, stability, moisture and other outside factors. One interaction in particular can be the bane of any coastal builder, and that’s the interaction of salt and metals. Salty air and moisture cause metal to corrode and slowly deteriorate. As a result, metal fasteners on buildings in coastal areas can lose their structural integrity from exposure to ocean air. The combination of oxygen, salt, and sodium chloride eats away at the metal, as airborne bacteria from the ocean also consume the iron and cause it to rust.
