Steel structure refers to a structural form that can withstand and transmit loads by connecting steel plates and hot-rolled, cold-formed or welded profiles through connectors. The steel structure system has comprehensive advantages such as 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 has unique advantages in the development of "high, large, and light" aspects. Globally, especially in developed countries and regions, steel structures have been reasonably and widely used in the field of construction engineering. The steel structure industry is usually divided into five subcategories: lightweight steel structures, high-rise steel structures, residential steel structures, spatial steel structures, and bridge steel structures.

Seismic resistance: The roofs of low rise villas are mostly sloping roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel components. After sealing the structural panels and gypsum boards, the light steel components form a very strong "plate rib structure system", which has stronger seismic resistance and resistance to horizontal loads, and is suitable for areas with seismic intensity above 8 degrees.

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

Durability: The light steel residential structure is entirely composed of cold-formed thin-walled steel components, and the steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet, effectively avoiding the influence of steel plate corrosion during construction and use, and increasing the service life of light steel components. The structural lifespan can reach 100 years.

Thermal insulation: The insulation material used is mainly fiberglass cotton, which has good thermal insulation effect. The insulation board used for exterior walls effectively avoids the "cold bridge" phenomenon of the wall and achieves better insulation effect. The thermal resistance value of R15 insulation cotton with a thickness of about 100mm can be equivalent to a brick wall with a thickness of 1m.

Soundproofing: Soundproofing effect is an important indicator for evaluating residential properties. The windows installed in the light steel system are made of insulated glass, which has good sound insulation effect and can achieve sound insulation of over 40 decibels; The wall composed of light steel keel and insulation material gypsum board can achieve a sound insulation effect of up to 60 decibels.

Health: Dry construction reduces the pollution caused by waste to the environment. 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 current environmental awareness; All materials are green building materials that meet ecological and environmental requirements and are beneficial to health.  ?

Comfort: The light steel wall adopts an efficient and energy-saving system, with breathing function and the ability to adjust indoor air dryness and humidity; The roof has ventilation function, which can create a flowing air space above the interior of the roof, ensuring the ventilation and heat dissipation needs inside the roof.

Quick: All construction work is done without being affected by environmental seasons. A building of about 300 square meters can complete the entire process from foundation to decoration in just 5 workers and 30 working days.

Environmental Protection: Materials can be 100% recycled, truly achieving green and pollution-free.

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

Steel structures are widely used in various engineering constructions, such as steel bridges, steel workshops, steel gates, various large pipeline containers, high-rise buildings, and tower rail mechanisms.
