The History of Steel Structure Development

Although China achieved early success in iron structures, it remained at the level of iron buildings for a long time. It wasn't until the late 19th century that modern steel structures were adopted in our country. After the founding of the People's Republic of China, the application of steel structures saw significant development, far surpassing the past in both quantity and quality. Light steel floor structures are composed of cold-formed thin-walled steel frames or composite beams, floor OSB structural boards, supports, connectors, and more. The materials used include定向刨花板, cement fiber boards, and plywood. These lightweight floors can bear loads of 316 to 365 kilograms per square meter.
