ROC participated in WOC 2019 in Las Vegas, the industry’s only annual international trade show dedicated to the global commerce of concrete and the concrete and masonry construction industry since 1975. We concluded the exhibition with a lot of interest from South American countries such as Mexico and the Dominican Republic, including the United States, and European countries such as the United Kingdom and France, as well as Chinese, Japanese, and Korean companies. We are pleased to bring a new image of the one-touch rebar coupler to many people in the rebar-related industries around the world.
