Advantages of Multi-storey Steel Frame Construction

Safety of Multi-storey Steel Frame Construction

Earthquakes

Earthquakes themselves do not cause harm to people. Fatal earthquakes cause buildings without seismic resistance to collapse, resulting in significant losses to the nation and society. In response to the frequent earthquakes in recent years, the government has placed great importance on building renovations. Traditional brick houses are no longer being promoted nationwide. Multi-storey steel frame construction that can withstand severe earthquakes has gradually replaced traditional houses.

Typhoons

Typhoons store a huge amount of energy and have very high wind speeds. Traditional houses under a typhoon with a speed of 100 meters/second will bear 2.5 tons of wind pressure per square meter, causing severe damage and collapse of steel structure houses. Multi-storey steel frame construction uses advanced double-sided galvanized light steel as the main body, combined with OSB board to form a light steel system. In coastal areas prone to typhoon, many places have built multi-storey steel frame construction.

Geological Disasters

In geological disaster areas, brick-concrete structure houses have excessive self-weight, causing partial subsidence of foundations and leading to house collapse. Multi-storey steel frame construction has a self-weight only one-fourth of brick-concrete structure houses and one-sixth of reinforced concrete houses, greatly reducing foundation costs and solving issues of partial subsidence and collapse of foundations and houses.

Cracks

Brick-concrete structure buildings often develop cracks, with the time and labor costs of repairs and rework affecting living conditions. Multi-storey steel frame construction consists of more than 10,000 components feature stable performance, high precision, complete overall structure, and flexible connections, making them not prone to cracking.

Comfort of Multi-storey Steel Frame Construction

Moisture Resistance

Due to the large amount of water sprayed during the construction of brick-concrete structure houses, water condensation will occur according to the external air humidity over the next 40 years. Long-term habitation is very detrimental to human health, leading to severe illnesses such as colds. Multi-storey steel frame construction are all water-free dry construction and are specially equipped with a moisture-proof breathable layer. Based on the size of water molecules, large water droplets are blocked outside the wall, while indoor water vapor is allowed to permeate in.

Insulation

The brick-concrete building materials have poor insulation, making them cold in winter and hot in summer. Most roofs require a half-layer of insulation, which not only fails to maintain waterproofing for the long term but also increases building costs. The composite walls of multi-storey steel frame construction have obvious insulation functions, avoiding the  "thermal bridge" phenomenon.

Construction Time

Traditional houses take a long time to build, making construction impossible in rainy, snowy, or frosty weather. Building a house takes more than a year. Multi-storey steel frame construction is not affected by the environment and seasons and can be constructed year-round.

Shape and Usable Area

Traditional buildings are made of cement, making them difficult to shape and achieve ideal architectural effects. The red brick walls of traditional houses are up to 24 centimeters long, with a usable area that only accounts for 70% to 80% of the building area. Multi-storey steel frame construction can be flexibly assembled from design to production, construction, and after-sales service, making it possible to achieve various architectural styles and fully showcase diversified building appearances.

Environmental Protection and Demolition

Building brick-concrete structure houses requires a large amount of water resources. The construction process generates noise and dust pollution. Road construction affects people's travel and lives. After house demolition, construction waste makes the land barren. Traditional brick-concrete structure houses are very difficult to demolish. Many large vehicles cannot enter the construction site. Multi-storey steel frame construction components are all factory-produced, with more than 90% of the main materials being recyclable. In the United States, 70% of house waste can be recycled. Multi-storey steel frame construction adopts pre-assembly and dry construction at the construction site, with no dust and large amounts of construction waste, uniform construction appearance, unified management, and civilized construction.
