Concrete vs Steel: What You Need to Know

Jan 20, 2020  Although concrete’s natural alkalinity reduces rebar corrosion, further protection may be needed for reinforced concrete exposed to seawater or large quantities of deicing salt. Epoxy-coated, stainless steel, or composite rebar work well for this purpose. Structural steel is as susceptible to corrosion as rebar and also requires protection.
