Seismic Resistance
Low-rise villas typically feature pitched roofs, with roof structures primarily composed of triangular trusses made from cold-formed, color-coated steel members. Once structural sheathing and gypsum board are installed, these light-gauge steel components form a highly robust "panel-rib structural system." This system offers superior seismic resistance and the ability to withstand lateral loads, making it suitable for regions with a seismic intensity of magnitude 8 or higher.
Wind Resistance
Buildings constructed with color-coated steel structures are lightweight, high-strength, possess excellent overall rigidity, and exhibit strong deformation capacity. Weighing only one-fifth as much as traditional brick-concrete structures, they can withstand hurricane-force winds of up to 70 meters per second, effectively protecting lives and property.
Durability
These structures are composed entirely of cold-formed, thin-walled steel members. The steel framework is crafted from high-strength, cold-rolled, galvanized sheets with advanced anti-corrosion treatment, which effectively prevents rust during both construction and long-term use, thereby extending the service life of the steel components. The structural lifespan can reach up to 100 years.
Thermal Insulation
The insulation used in the color-coated sandwich panels-primarily fiberglass wool-provides excellent thermal performance. When applied to exterior walls, these insulation panels effectively eliminate "thermal bridges," ensuring superior thermal efficiency. For instance, a layer of R15 insulation wool approximately 100mm thick offers a thermal resistance equivalent to that of a 1-meter-thick brick wall.
Sound Insulation
Sound insulation is a key metric for evaluating residential buildings. Windows installed in these light-gauge steel systems utilize double-glazed (hollow) glass, providing effective noise reduction of over 40 decibels. Furthermore, wall assemblies-comprising light-gauge steel framing, insulation materials, and gypsum board-can achieve sound insulation levels of up to 60 decibels.
Health and Environmental Impact
The construction process relies on "dry" methods, which minimize environmental pollution from waste. Most auxiliary materials are recyclable, aligning with modern environmental standards. All materials used are classified as "green" building materials, meeting ecological requirements and promoting a healthy living environment.
Comfort
The color-steel wall system is highly energy-efficient and features a "breathing" function, which helps regulate indoor humidity levels. The roof is designed with a ventilation system that creates an airflow space beneath the roof structure, ensuring proper ventilation and heat dissipation.
Efficiency
Construction relies entirely on "dry" methods, making it independent of environmental or seasonal constraints. A building of approximately 300 square meters can be completed-from foundation to interior finishing-by a crew of five workers in just 30 working days.
