Characteristics of earthquake-resistant steel structures：

1. Light in weight and high in strength, the weight of a residence built with steel structure is about half that of a reinforced concrete residence. It meets the need for large open Spaces in residences, and the usable area is about 4% higher than that of reinforced concrete residences.

2. Safety and reliability, with good seismic and wind resistance performance.

3. Steel structure components are fabricated in factories, reducing on-site workload, shortening construction periods, and meeting industrialization requirements.

4. The steel structure factory has reliable production quality, precise dimensions, convenient installation and easy coordination with related components.

5. Steel can be recycled and causes less pollution to the environment during construction and demolition.
