Steel structure plant has many unique characteristics and advantages. 

First of all, a significant feature of the steel structure plant is the large span. Compared with reinforced concrete, steel structure has better advantages in beam depth and span between columns. For example, the general depth to span ratio of reinforced concrete beams is about 1:12, while that of steel structures is 1:24. This means that steel buildings can be designed to be more spacious and flexible.

Secondly, the steel structure is light in weight. In general, the ratio of steel structure to reinforced concrete weight is about 1:1.6. Since the seismic force is proportional to the mass, the lighter the weight, the smaller the seismic force. If the steel structure is properly treated, its earthquake resistance will be more effective. In addition, the steel structure plant adopts the method of prefabrication, which can manufacture a large number of components in the factory, reduce labor costs, speed up construction, shorten the construction period, and ensure quality.

Third, the steel structure itself has a high toughness. Through proper composition and heat treatment, the strength and toughness of the steel structure can be improved, thus improving safety. The steel structure also has a strong elasticity, which can be used to design difficult buildings with large spans and special shapes.

Fourth, the factory building with steel structure looks beautiful and generous. The use of colorful steel plates, aluminum alloys, glass curtain walls and other diverse supporting materials can create beautiful and generous buildings. These materials can be combined as needed to create unique architectural styles.

Finally, the single span beam rigid frame series and the single span steel beam series are widely used in building systems. They are suitable for industrial and commercial plants, indoor sports venues and other steel structure plants. Because of its many advantages, such as factory production, site construction is convenient and fast, strong and durable, novel appearance, high quality and high efficiency, suitable price, column mesh size can be freely arranged according to needs, can meet different climate environment and different use requirements, steel structure plant has been widely used in modern buildings.
