冷弯C型钢是指由钢板或带钢在常温下弯曲而成的各种截面形状的钢材成品。由于冷弯型钢具有重量轻、节约钢材、结构高、性能好、 工业化程度高、建设周期短、经济和环境效益明显等诸多优点，近年来得到越来越多的应用。 .在建筑结构中。 随着我国经济建设的发展和生产技术的提高，冷弯镀锌C型钢结构以其诸多优势逐渐被市场认可和重视， 在民用建筑中具有很大的发展潜力。冷弯C型钢在欧美发达地区的建设中发挥了非常重要的作用。它是建筑行业的主要建筑材料。 其消耗量占钢材总量的5%。在建筑行业，冷弯型钢占冷弯型钢总产量的70%以上，而在日本已达到80%以上。2011年， 我国生产钢材6.9亿吨，而冷弯型钢产量不足1000万吨。冷弯型钢产量占钢材总产量的比重过低，与发达国家仍有较大差距。 Cold-bent C-type steel refers to the finished steel product made of steel plate or strip steel bent at room temperature. Because cold-bending steel has many advantages of light weight, saving steel, high structure, high performance, high degree of industrialization, short construction cycle, obvious economic and environmental benefits, more and more applications in recent years.. In building structures.With the development of China's economic construction and the improvement of production technology, cold-bent galvanized C-shaped steel structure is gradually recognized and valued by the market with its many advantages, which has great development potential in civil buildings. Cold-bending C-type steel plays a very important role in the construction of developed areas in Europe and America. It is the main building material in the construction industry.Its consumption accounts for 5% of the total steel product.In the construction industry, cold-bent steel accounts for more than 70% of the total cold-bent steel production, while in Japan, it has reached more than 80%.In 2011, China produced 690 million tons of steel, while cold-bending steel produced less than 10 million tons. The proportion of cold-bending steel production in the total steel production is too low, and there is still a large gap with developed countries.
