General Information

Websteel Building System

WEBSTEEL building system originates from Canada and has been applied in many countries in North America for more than 20 years. Currently, it is the only technology, which can adopt 100% cold-formed thin-walled steel to construct buildings with up to 6 stories, and can be adopted for every climate conditions.

The main body of building members for the websteel system is a miniature bridge frame which is composed of light, thin wall square tube (rectangular tube) undergoing galvanization cold-formed high-frequency welding and triangular V-shaped connector. This bridge frame may be adopted for building beam, wall, floor, as well as roof. In a word, miniature bridge frame adopting this rectangular tube structure may be used in all kinds of building elements.

Together with the increasing of the usage of light steel frame construction around the world in the recent years, the structural and decoration boards industry has made significant steps for improvement. New materials with high quality specification are available now in the market. Combining these materials together with the web steel frame system, we are in position to propose to our customers building solutions that create a new understanding of living culture with environmental competence and harmony.

Aplication:

1). Light steel residential and office buildings up to 6 storeys

2). Infill partitions – the excellent fire resistance, structural strength and sound and heat insulation characteristics of the websteel wall system offers a fast, low cost, flexible for future modifications and high safety partitions system in both heavy steel and reinforced concrete frame buildings in low and high rise buildings.

Technical Inforamtion:

1). Firm intensity, anti-wind and anti-earthquake

Main body miniature bridge frame of WEBSTEEL building system is composed of tube with the square, rectangular cross section and V-shaped connector. As it is well known, it is not easy for hollow structure steel to undergo distortion and in combination with the connection method of triangular bridge frame, which results in even force transmission and distribution and integrated load transmission system. The abilities of anti-distortion, anti-multidimensional load and anti-horizontal load are enhanced. WEBSTEEL has the structure of shear-wall hinge joint, and force transmission route of the whole building is plate-shear-wall-foundation with integrated load transmission system. It is proved by experiments that this structure is more resistant to horizontal load than frame structure and may absorb and consume a great number of external energy by transformation owing to appropriate flexibility and intensity of bridge frame, and the damage caused by suddenly external load is decreased with the ratio of material intensity and weight increased. Therefore comparing to other light steel structure, the whole building can bear more loads.

2). Energy-saving, sound insulation

Wall and floor plate of WEBSTEEL building are composed of independent bridge frame with two tube fittings, 2 rectangular tubes are discontinuously connected by V-shaped connector of less than 2 mm, and heat transfer route is minimal with thermal bridge completely separated, hence it is almost impossible for internal and external heat transfer, which makes two independent heat-cycle systems without interference for inside and outside of the building. Square tube(rectangular tube) with hollow structure achieves interferential and decreasing effects on sound conduction. The glass cotton which is filled in vacant space of bridge frame achieves the excellent functions of vibration isolation, sound absorption, and the invasion of external noise and disorderly vibration is isolated. Heat transfer coefficient, U=0.24w/(m2.K), non-bearing wall air-borne sound insulation volume, Rw=50dB, and bearing wall air-borne sound insulation volume, Rw=51dB, all of which demonstrate that this structure achieves great thermal insulation and sound insulation performances.

3). Safeguard for fire prevention

There are three reasons for WEBSTEEL building’s high fire resistance:

the first one is its structure - even if local fire occurs, WEBSTEEL spatial grid structure may obtain support through nearby bridge frames;

the second one is bridge frame itself - triangular connection of bridge frame makes the heat transfer route become curvilinear, therefore heat diffusion during fire disaster may be stopped. Even if the fire is too strong and one side is fired to soften, the square tube of the other side keeps unchanged which can bear the load of the building;

the third one is combined indoor decoration board – high fire resistance boards with great performances are wrapped on both sides of the weight-bearing members, that protect the websteel members from the temperature rise. Websteel structure conforms to international fire-prevention regulations, since it is fire rated for minimum 2.5 hours.

4). Being beneficial for environment protection

Field construction with websteel rarely generates wastes or noise. Once the house reconstruction is needed in the future, the disassembled members can be reused with the recovery rate of up to 90%, which completely abides by the Evaluation System for Green Ecological Building prescribed by developed countries, such as 2nd edition of “Evaluation System for Green Building” issued by U.S. Green Building Council and related regulations of “Technical Essentials for Construction of State Comfortable Housing Estate Pilot Project” and the European Sustainability Guide. WEBSTEEL building needs no red bricks, which protects arable lands. Large areas of farmland are destroyed due to preparing red bricks by fire. If WEBSTEEL can replace red brick, not only living problem of people can be solved, but also the goal of sustainable development can be achieved in city construction.
