Each year, the direct cost of steel corrosion to the U.S. economy is $276 billion, or 3.1% of its gross domestic product. That’s according to a study by Houston-based NACE International–The Corrosion Society titled “Corrosion Costs and Preventive Strategies in the United States.” With so much potential to help mitigate these costs, it’s expected that inventors are searching for the latest breakthrough in the science of rebar-corrosion protection.
