以钢材制作为主的结构，是主要的建筑结构类型之一。钢材的特点是强度高、自重轻、整体刚性好、变形能力强，故用于建造大跨度和超高、超重型的建筑物特别适宜；材料匀质性和各向同性好，属理想弹性体，最符合一般工程力学的基本假定；材料塑性、韧性好，可有较大变形，能很好地承受动力荷载；建筑工期短；其工业化程度高，可进行机械化程度高的专业化生产。钢结构今后应研究高强度钢材，大大提高其屈服点强度；此外要轧制新品种的型钢，例如H型钢（又称宽翼缘型钢）和T形钢以及压型钢板等以适应大跨度结构和超高层建筑的需要。
Steel based structures are one of the main types of building structures. The characteristics of steel are high strength, light weight, good overall rigidity, and strong deformation ability, making it particularly suitable for constructing large-span, ultra-high, and ultra-heavy buildings; The material has good homogeneity and isotropy, belongs to the ideal elastic body, and most conforms to the basic assumptions of general engineering mechanics; The material has good plasticity and toughness, can undergo significant deformation, and can withstand dynamic loads well; Short construction period; It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization. In the future, high-strength steel should be studied in steel structures to greatly improve their yield point strength; In addition, new types of steel profiles, such as H-beams (also known as wide flange steel), T-beams, and profiled steel plates, need to be rolled to meet the needs of large-span structures and super high-rise buildings.
另外还有无热桥轻钢结构体系，建筑本身是不节能的，本技术用巧妙的特种连接件解决了建筑的冷热桥问题；小桁架结构使电缆和上下水管道从墙里穿越，施工装修都方便；无比节能是世界上唯一的一家以冷弯薄壁型钢建7层住宅的建筑体系。
In addition, there is a light steel structure system without a thermal bridge, and the building itself is not energy-saving. This technology solves the problem of cold and hot bridges in buildings with clever special connectors; The small truss structure allows cables and water supply and drainage pipes to pass through the wall, making construction and decoration convenient; Extremely energy-efficient is the only building system in the world that uses cold-formed thin-walled steel to build a 7-story residential building.
在我国，钢结构行业的市场化程度较高，市场竞争较为激烈。目前我国钢结构企业在4,000-5,000 家左右。据中国钢结构协会统计，截至目前，拥有钢结构制造企业资质的单位共238 家，但多数为年产1 万吨以下的中小企业，年产10 万以上的企业仅30 多家。大部分企业生产规模较小，行业集中度不高
In China, the steel structure industry has a high degree of marketization and fierce market competition. At present, there are around 4000-5000 steel structure enterprises in China. According to statistics from the China Steel Structure Association, as of now, there are a total of 238 units with steel structure manufacturing enterprise qualifications, but most of them are small and medium-sized enterprises with an annual output of less than 10000 tons, and only more than 30 enterprises with an annual output of more than 100000 tons. Most enterprises have relatively small production scales and low industry concentration
