Ten advantages of steel structure will be beneficial to extend the life of the building

- Aug 13, 2018 -

  Steel structure refers to a structure that can withstand and transmit loads by connecting steel plates and hot-rolled, cold-bent or welded profiles through joints. The steel structure system has the advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery and less environmental pollution. Compared with reinforced concrete structures, it has more 'high, large and light'. The unique advantages of the development of the three aspects have been reasonably and widely applied in the field of steel structure construction engineering in the global scale, especially in developed countries and regions.

Earthquake resistance: Most of the roofs of low-rise villas are sloping roofs. Therefore, the roof structure basically adopts a triangular roof truss system made of cold-formed steel members. The light steel members form a very strong structure after sealing the structural plates and gypsum boards. Robust "ribbed structural system", this structural system has stronger seismic and resistance to horizontal loads, and is suitable for areas with seismic intensity of 8 degrees or more.

Wind resistance: The steel structure has light weight, high strength, good overall rigidity and strong deformation ability. The building's own weight is only one-fifth of the brick-concrete structure, which can withstand hurricanes of 70 meters per second, so that life and property can be effectively protected.

Durability: The light steel structure residential structure is composed of cold-formed thin-walled steel component system. The steel bone is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of corrosion of the steel plate during construction and use, and increases the light steel component. Service life. The structural life can reach 100 years.

Insulation: The thermal insulation material used is mainly made of glass wool, which has good thermal insulation effect. With the insulation board of the outer wall, the phenomenon of 'cold bridge' of the wall is effectively avoided, and a better thermal insulation effect is achieved. The thermal resistance of R15 insulation cotton with a thickness of about 100mm can be equivalent to a brick wall of 1m thick.

Sound insulation: The sound insulation effect is an important indicator for evaluating the house. The windows installed in the light steel system are all insulated glass, with good sound insulation and sound insulation of more than 40 decibels. The wall made of light steel keel and thermal insulation gypsum board is soundproofed. The effect can be as high as 60 decibels.

Health: dry work construction, reduce the pollution caused by waste to the environment, housing steel structure materials can be 100% recycled, and other supporting materials can also be mostly recycled, in line with current environmental awareness; all materials are green building materials to meet ecological requirements, good for health.

Comfort: The light steel wall adopts high-efficiency energy-saving system, has breathing function, can adjust the indoor air dry humidity; the roof has ventilation function, which can form the flowing air between the interior of the house to ensure the ventilation and heat dissipation requirements inside the roof.

Fast: All dry work construction is not affected by the environmental season. A building of about 300 square meters, only 5 workers and 30 working days can complete the whole process from foundation to decoration. Environmental protection: The material can be 100% recycled, truly green and non-polluting.

Energy-saving: All adopt high-efficiency energy-saving walls, which have good insulation, heat insulation and sound insulation effects, and can reach 50% energy-saving standards.
