EPOXY INTEREST GROUP ® EPOXY-COATED REINFORCING STEEL 40 YEARS Celebrate In 2013, we celebrate the 40th Anniversary of Epoxy-Coated Reinforcing Steel. Epoxy-coated reinforcing steel was frst used in Pennsylvania in 1973 based upon extensive research by the National Bureau of Science. It has been used worldwide and is used extensively in the USA, Canada, Japan, China, India and the Middle East. Epoxy-coated reinforcing steel has been used in over 74,000 bridge decks covering 850,000,000 ft 2 in the USA alone. During the past 40 years, changes have been made to the coating and application processes that are not visible to the customer. These changes have resulted in epoxy-coated reinforcing steel products that are more fexible, robust and durable, and are refected in the product specifcations ASTM A775 and ASTM A934 for reinforcing bar and ASTM A884 for welded wire fabric.
