Iran's first mass production of checkered steel sheet, with a capacity of 200,000 tons per year, has been inaugurated in Mobarakeh Steel Company, announced Iranian Mines and Mining Industries Development and Renovation Organization on Saturday. Since the annual domestic demand for this steel product is 100,000 tons, the remaining half can be shipped overseas, IMIDRO said. The sheets have a width of 800 to 1,550 millimeters and a thickness of 2 to 10 millimeters, and are offered in the three classes of ST44-2, ST37-2 and ST52-2. Chekered steel sheets are used in the making of industrial stairways, bridges, autos, wagons, ships and ports.
