Advantages of steel structures

The steel structure system has the comprehensive advantages of light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it is more "tall, large, and light" With the unique advantages of development in three aspects, this article mainly outlines the advantages of steel structures.

Earthquake resistance: Most of the roofs of low-rise villas are sloped roofs, so the roof structure basically uses a triangular roof truss system made of cold-formed steel components. After the light steel components are sealed with structural plates and gypsum boards, they form a very Strong "plate rib structural system", this structural system has stronger ability to resist earthquakes and horizontal loads, and is suitable for areas with seismic intensity above 8 degrees.

Wind resistance: The steel structure building has light weight, high strength, good overall rigidity and strong deformation ability. The building's self-weight is only one-fifth of that of a brick-concrete structure, and it can withstand hurricane winds of 70 meters per second, effectively protecting life and property.

Durability: The light steel structure residential structure is all composed of cold-formed thin-walled steel component systems. The steel frames are made of super anti-corrosion high-strength cold-rolled galvanized sheets, which effectively avoids the impact of corrosion of steel sheets during construction and use, and increases the durability of light steel components. service life. The structural life can reach 100 years.

Thermal insulation: The thermal insulation material used is mainly fiberglass cotton, which has good thermal insulation effect. The use of thermal insulation boards on exterior walls can effectively avoid the "cold bridge" phenomenon in the wall and achieve better thermal insulation effects. The thermal resistance value of R15 insulation cotton about 100mm thick can be equivalent to that of a 1m thick brick wall.

Sound insulation: Sound insulation effect is an important indicator for evaluating residences. The windows installed in the light steel system are all made of insulating glass, which has good sound insulation effect, with a sound insulation of more than 40 decibels; the wall composed of light steel keels and insulation material gypsum board has good sound insulation The effect can be as high as 60 decibels.

Healthy: Dry construction reduces environmental pollution caused by waste. The steel structure materials of the house can be 100% recycled, and most of the other supporting materials can also be recycled, which is in line with the current environmental awareness; all materials are green building materials and meet the requirements of the ecological environment. Good for health. ?

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

Fast: all construction work is done, not affected by environmental seasons. For a building of about 300 square meters, it only takes 5 workers and 30 working days to complete the entire process from foundation to decoration.

Environmentally friendly: The materials are 100% recyclable, truly green and pollution-free.

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