Posco’s new steel recognized for ability to block out noise
One of Posco’s world-first steels, called high-manganese steel, received a grade one certification by the state-run Korea Institute of Civil Engineering and Building Technology for its ability to reduce noise by up to 90 percent. It is the first time a steel has been given top marks for its ability to block noise.In Korea, apartments are supposed to be built with materials like styrofoam or rubber to keep noise below 58 decibels. But Posco’s new steel kept noise below 43 decibels during an experiment at a state-run certification institute. With the new recognition, Posco hopes to supply some 20,000 tons of this steel to local apartment construction market.
