Multi-Story Prefabricated Steel Structure Apartment Building Residential Dormitory Construction

Multi-story prefabricated steel structure apartment and dormitory buildings are modern, eco-friendly, and fast-construction residential building solutions developed for temporary and permanent residential needs. Different from traditional concrete residential buildings, this series of residential structures adopts modular factory prefabrication and on-site bolted assembly technology, which effectively solves the points of long construction cycle, high on-site pollution, poor flexibility and high comprehensive cost of traditional buildings. The product can be customized with 2–6 floors according to customer demands and site conditions, widely applicable to staff dormitories, worker accommodation apartments, construction site temporary residences, school dormitories, rural residential buildings, and temporary residential supporting facilities for industrial parks. Featuring lightweight structure, high safety factor, flexible layout, beautiful appearance and recyclable utilization, it has become the mainstream preferred residential building type for modern engineering construction and industrial supporting projects.

All main structural components are pre-processed and prefabricated in the factory with precise dimensional calibration and standardized production processes. The on-site construction only requires assembly and fixation, which greatly shortens the project delivery cycle. Meanwhile, the steel structure has excellent seismic resistance, wind resistance and structural stability, fully meeting national and international residential building safety standards, and can provide comfortable, safe and stable living space for long-term use.

Our multi-story steel structure residential buildings are equipped with a complete, high-performance building enclosure system, focusing on heat insulation, sound insulation, fire resistance, waterproofing and anti-corrosion performance to ensure comfortable living experience. The wall enclosure adopts high-quality color steel sandwich panels, with core materials including rock wool, glass wool and EPS foam, which can be selected according to different fire protection and heat preservation requirements. The rock wool sandwich panel enclosure has excellent A-level fireproof performance, effectively blocking flame spread and improving building safety; the integral wall panel has good thermal insulation performance, which can isolate external high temperature and cold air, realizing warm in winter and cool in summer, and reducing daily energy consumption for air conditioning and heating.

The roof enclosure system adopts waterproof and heat-insulating integrated roof panels, matched with professional waterproof grooves and sealing accessories, which can effectively prevent rainwater leakage and solve the waterproof points of traditional temporary buildings. The floor system uses high-strength cement fiber pressure plates or galvanized steel floor decks, with strong bearing capacity, no deformation, stable and wear-resistant, meeting the daily walking and furniture placement needs of residential spaces. All enclosure panels are installed with precise closing process, with tight overall sealing, excellent sound insulation effect, which can effectively isolate external noise and ensure a quiet living environment. In addition, the enclosure system has outstanding anti-corrosion and anti-aging performance, with long service life and no frequent maintenance required in the later stage.

To solve the problems of poor air circulation and stuffy indoor environment of traditional prefabricated buildings, our multi-story steel structure apartment dormitory is equipped with a scientific and reasonable full-house ventilation system, combining natural ventilation and auxiliary mechanical ventilation to ensure fresh indoor air all the time. In terms of natural ventilation design, each residential room is equipped with high-transparency aluminum alloy sliding windows or casement windows with large ventilation area. The windows adopt waterproof and dustproof design, which can flexibly adjust the ventilation volume according to outdoor weather conditions. The building overall adopts a staggered window opening layout, forming a smooth indoor and outdoor air convection channel, realizing efficient natural air circulation and improving indoor air quality.

For indoor closed areas and rooms with poor natural ventilation conditions, we support customized installation of exhaust fans, ventilation ducts and fresh air systems. The centralized ventilation system can effectively exhaust indoor humid air, peculiar smell and turbid air, and continuously input fresh outdoor air, avoiding indoor mildew, dampness and air turbidity. The ventilation system is reasonably arranged without occupying indoor living space, with low noise and low energy consumption during operation. It effectively improves residential comfort, ensures the health of residents, and adapts to long-term centralized living scenarios such as staff dormitories and school dormitories.

This multi-story prefabricated steel structure residential building has strong versatility and flexibility, covering multiple residential and supporting scenarios, with extremely high practical value and market applicability. First, it is widely used in engineering construction fields, serving as temporary staff dormitories, project department office and residential integrated buildings, solving the accommodation needs of construction workers and project management personnel. Second, it is applicable to industrial park supporting facilities, used as factory staff apartments and collective dormitories, providing standardized and comfortable living supporting services for enterprise employees.

Third, it can be used as campus supporting buildings, including school student dormitories and teacher apartments, with safe structure and comfortable space, meeting campus living standards. Fourth, it is suitable for temporary resettlement projects such as disaster relief resettlement and municipal temporary residential construction, with fast construction speed and stable performance. In addition, it can also be customized into permanent rural residential buildings, scenic area supporting accommodation buildings, and commercial short-term rental apartments, realizing multi-scene and multi-functional use.

First, superior structural safety and durability. We adopt high-standard Q235B and Q355B high-strength steel as the main frame materials, with scientific structural stress calculation and modular overall design. The steel frame has strong seismic resistance, wind resistance and pressure resistance, and can adapt to various complex climatic environments. All steel components undergo professional sandblasting rust removal and multi-layer anti-corrosion spraying treatment, with strong anti-rust and anti-aging capabilities, ensuring a service life of more than 50 years for permanent use.

Second, ultra-fast construction and cost savings. Adopting full factory prefabrication and on-site bolted assembly mode, no complex on-site welding and concrete pouring construction is required. The construction cycle is shortened by 70% compared with traditional concrete buildings, which can quickly complete project delivery and put into use, greatly saving time cost and labor cost for customers. The lightweight steel structure also reduces foundation construction investment, with lower overall comprehensive cost.

Third, comfortable and humanized living design. Equipped with high-performance fireproof, heat-insulating and sound-insulating enclosure system and scientific circulating ventilation system, the building realizes constant temperature, quiet and fresh indoor living environment. The indoor layout is flexible and customizable, supporting independent rooms, shared corridors, independent toilets and other functional designs, fully meeting daily living and learning needs.

Fourth, green environmental protection and reusable. The whole building is assembled with modular components, with no construction waste and no environmental pollution during construction. All steel components can be disassembled, transported and reassembled, realizing secondary reuse, which greatly improves resource utilization rate and conforms to the global green building development concept.

Fifth, one-stop professional service. We provide full-process customized services from scheme design, drawing customization, factory production, standardized transportation to on-site installation guidance. Complete installation manuals and technical supporting materials are provided for each project, with professional remote technical guidance and after-sales service, allowing customers to save worry, effort and cost throughout the whole process.
