Originally named after a form of low-quality steel cooled in long moulds directly on the ground without continuous casting and direct rolling, the term now refers to poorly manufactured steel product in general. It is often made in small workshop-style factories from melted scrap iron and steel, making chemical composition and quality difficult to control. Though no official figures exist, industry insiders estimate production capacity to be around 100 million tonnes. Posing a threat to construction quality and the environment, the government targeted eliminating substandard steel capacity by end June 2017 as part of de-capacity efforts.
