In Qianjiang Century City, Hangzhou, a 310 meter high, steel structure connected Hangzhou Century Center (Hangzhou Gate) stands out with great momentum. Not far from the Hangzhou Century Center, the Hangzhou Qianjiang Century City Talent Special Housing, which has been listed as the “National Healthy Housing Demonstration Project”, has also been successfully put into use, and has pioneered the promotion and application of steel structure housing in affordable housing projects. It is the leading steel structure affordable housing community in China in terms of area.
These two iconic projects were both constructed by Hangxiao Steel Structure, the first steel structure residential industrialization base in Hangzhou. Recently, reporters conducted a survey and interview at Hangxiao Steel Structure, and learned that under the promotion of China’s “dual carbon” strategic goals and the “new urbanization construction” policy, the steel structure industry has once again entered an upward cycle. Large steel structure enterprises with green and low-carbon development concepts are facing new development opportunities. However, due to factors such as low awareness of green buildings in the whole society and the dominance of traditional building models, compared to developed countries such as Japan and the United States, steel structure residential buildings in China are still in the initial stage of development, and industrialization still needs to be accelerated.
Prefabricated buildings create a new look for a green new city
Hangzhou Century Center, China International Silk Road Center Building, Qatar Doha International Airport… These are the epitomes of Hangxiao Steel Structure Co., Ltd.’s recent undertaking of major construction projects at home and abroad and the application of green building concepts.
The use of steel structures in commercial buildings has become very common, and the use of steel structures in residential buildings is also being explored and challenged by the industry.
More than 60 workers completed a 32 story residential building with a building area of over 20000 square meters in just 58 days. “Liu Xiaoguang, the chief engineer of Hangxiao Steel Structure, pointed to Building 11, a talent special building in Qianjiang Century City, Hangzhou, behind him, and told reporters that if the same building uses traditional reinforced concrete structures, the main structure usually takes 180 workers about 6 months to complete.
Unlike traditional building methods, this type of prefabricated steel structure building is like “building blocks” – steel columns, beams, floor support plates, wall panels, stairs and other building components and accessories are processed and manufactured in the factory, transported to the construction site, and then reliably connected to install the components and accessories together, completing a complete building.
Nowadays, prefabricated buildings are widely used in public buildings, resettlement houses, municipal roads… Thousands of prefabricated components like building blocks are “building” a green, modern, and livable new urban appearance.
“Compared with traditional buildings, prefabricated buildings have four major advantages – ‘more, faster, better, and more economical’.” Jiang Huancheng, an academician of the CAE Member and an academician of Hangxiao Steel Structure Workstation, introduced that “more” refers to more application scenarios of prefabricated systems; Fast “refers to the high degree of prefabrication in the factory and the overall short construction period; ‘Good’ refers to the components and accessories produced by the factory with exquisite effects, unified standards, and controllable quality; The “province” is because steel components are produced in factories, reducing on-site water consumption, reducing construction waste and dust pollution, and steel components can also be recycled.
Continuous efforts in green building material innovation
Steel structure buildings are a new type of green and low-carbon building system, widely favored by various parties in the industry. Promote policies such as green buildings, energy conservation and environmental protection, and resource recycling in the country
