Structural Steel Engineering Structural steel engineering primarily involves the use of steel in construction, comprising steel beams, columns, trusses, and other components mainly made from sections and plates. These components are typically connected by welds, bolts, or rivets, making it one of the primary types of building structures. Due to its light weight and ease of construction, it is widely used in large factories, stadiums, and high-rise buildings. Advantages of Structural Steel: - Seismic Resistance: Low-rise villa roofs are mostly sloped, so the roof structure usually employs a triangular truss system made of cold-formed steel sections. After covering with structural boards and gypsum boards, the light steel components form a very robust "plate rib structure system" with strong seismic resistance and the ability to withstand horizontal loads, suitable for areas with seismic intensity above 8 degrees. - Wind Resistance: Structural steel buildings are lightweight, high in strength, have good overall rigidity, and are resistant to deformation. The weight of the building is only one-fifth of that of brick-concrete structures, capable of withstanding hurricanes with wind speeds of up to 70 meters per second, effectively protecting life and property. - Durability: The residential structure of light steel is composed entirely of cold-formed thin-walled steel components. The steel frame is made from high-grade corrosion-resistant cold-rolled galvanized steel plates, effectively preventing rust during construction and use, thereby extending the service life of the light steel components. The structural lifespan can reach *. - Insulation: The main insulation material used is glass fiber cotton, providing excellent thermal insulation. The insulation boards used on the exterior walls effectively prevent the "cold bridge" phenomenon, achieving good insulation effects. A 100mm thick R15 insulation cotton has a thermal resistance equivalent to that of a 1m thick brick wall. - Soundproofing: Soundproofing is an important indicator for residential buildings. Windows installed in the light steel system are made with double-glazed glass, offering good soundproofing with a rating above 40 decibels. The walls composed of light steel studs, insulation materials, and gypsum boards can achieve a soundproofing rating of up to 60 decibels. - Health: Dry construction methods reduce environmental pollution from waste, and the steel materials used in the building are recyclable, as are most of the other supporting materials, in line with current environmental awareness. All materials are green building materials, meeting ecological requirements and conducive to health. - Comfort: Light steel walls use an energy-saving system with breathable functions, allowing for regulation of indoor air humidity. The roof has ventilation features, ensuring the house is well-ventilated and thermally dissipative. - Speed: All dry construction, unaffected by environmental or seasonal conditions. A building of about 300 square meters can be completed from foundation to decoration in just 30 workdays by a team of 5 workers. - Environmental Protection: Materials are recyclable, ensuring true green and pollution-free construction. - Energy Efficiency: All energy-saving walls provide good insulation, heat retention, and soundproofing, meeting 50% energy-saving standards.
