the number of steel structure buildings indicates the economic strength and development degree of a country or a region. Since 2, China's national economy has grown significantly, its national strength has been significantly enhanced, and steel production has become a world power. It has been proposed to "actively and reasonably use steel" in buildings, and since then, the shackles of "restricting the use of steel" have been shaken off, and steel structure buildings have gradually increased in economically developed areas. Especially around 28, under the impetus of the Olympic Games, there was a boom in steel structure construction. Strong market demand promoted the rapid development of steel structure construction, and a large number of steel structure venues, airports, stations and high-rise buildings were built, which led to the development of a large number of steel grating manufacturers.
