The steel structure project of China Hainan Walton Glass Factory is a typical single-layer steel structure factory building with a construction area of about 3850 square meters. The comprehensive steel consumption is about 1400 tons, and the steel consumption per square meter is about 36kg. The steel columns are made of H-shaped steel columns, and the steel beams are made of H-shaped steel beams. The production cost of profiles is low and the speed is fast. There is no need for manual splicing during the construction process, which not only reduces costs but also shortens the construction period.
