On April 25, China's first low-carbon emission H-beam product rolled off the production line at the Ma'anshan Iron & Steel Co., Ltd. (Ma Steel) heavy H-beam production line and was officially launched. Over the past two years, Ma Steel has successively released Environmental Product Declarations (EPDs) for large, small, and heavy H-beams on China's steel industry EPD platform, being the first in the country to do so.
