Rigid Steel Frame Homes
Rigid steel structure houses are reshaping the modern construction industry standards with their excellent safety, efficient construction speed and sustainability. Whether it is to cope with the challenges of frequent natural disasters or meet the needs of rapid urban expansion, it provides both economical and innovative solutions.
Product Introduction
What is a rigid steel structure house?
Rigid Steel Frame Homes is a building system that uses high-strength steel as the main frame and is constructed through rigid connection nodes (such as welding or high-strength bolts). Its core features are strong structural stability and high deformation resistance, and it can withstand greater loads and extreme environmental challenges. Compared with traditional concrete or flexible steel structures, rigid steel structures perform better in terms of earthquake resistance, wind resistance, and settlement resistance, and are widely used in high-rise residential buildings, industrial plants, and construction projects in special geological areas.
Core advantages of rigid steel structure houses
Extraordinary structural stability
High-strength bearing: The yield strength of steel can reach more than 350MPa, and the overall rigidity of the frame is significantly higher than that of traditional concrete structures, which can withstand earthquakes (above level 8), typhoons (level 15) and extreme climates.
Anti-settlement design: Through precisely calculated node rigid connections, the stress caused by uneven foundation settlement is effectively dispersed to avoid wall cracking.
Rapid industrialized construction
The factory prefabrication rate exceeds 90%: beams, columns, floor slabs and other components are all standardized in the factory, with errors controlled within ±2mm, and only mechanized lifting and splicing are required on site.
Construction period shortened by 60%: Taking a 200㎡ two-story house as an example, traditional construction takes 6-8 months, and rigid steel structure can be delivered in only 3-4 months.
Green, environmentally friendly and sustainable
Material recyclability: The steel recycling rate is as high as 95%, and there is no construction waste left after demolition, which meets the "dual carbon" goal.
Excellent energy-saving performance: The wall adopts a composite structure of rock wool + OSB board, with a thermal insulation coefficient of 0.18W/(㎡·K), which saves more than 40% energy compared with brick-concrete structure.
Flexible space design
Large-span column-free space: The span of the steel beam can reach 12 meters, realizing the integrated design of the living room and dining room to meet the needs of personalized layout.
Convenient secondary transformation: Non-load-bearing walls can be adjusted freely, and there is no need to rebuild the main structure for later expansion.
Design highlights of rigid steel structure houses
Diversified apartment adaptation & intelligent integrated system & fusion of aesthetics and functionality
Single-family housing
From 50㎡ single-family apartments to 300㎡ single-family villas, supporting various housing types such as lofts, split-levels, and mezzanines.
Collective housing
Suitable for multi-story apartments and townhouse communities, improving land utilization through modular combinations.
Prefabricated interior decoration
pre-buried pipelines, integrated ceiling, dry ground leveling technology, shortening the decoration period.
Energy management
The roof has a reserved photovoltaic installation interface, which is matched with the energy storage system to achieve energy self-sufficiency.
Appearance customization
It can be adapted to modern minimalist, industrial style, European classical and other facade styles. The combination of metal texture and glass curtain wall enhances the building's recognition.
Anti-rust and anti-corrosion treatment
hot-dip galvanizing coating + outdoor special powder spraying, with a service life of more than 50 years (salt spray test ≥1000 hours).
Applicable scenarios of rigid steel structure houses
| Scene type | Application advantages |
|---|---|
| Residential buildings in high seismic zones | Rigid node design absorbs earthquake energy, reduces structural damage, and ensures residential safety. |
| Buildings in coastal areas | Galvanized steel components are resistant to salt spray corrosion, with a wind pressure strength of 2.5kPa, and can resist typhoons. |
| Frozen/soft soil foundations | Lightweight structure reduces foundation treatment costs (40% lighter than concrete structure) and adapts to complex geological conditions. |
| Commercial complexes | Large span space meets the needs of shopping malls and exhibition halls, with a short construction period and can be put into operation quickly. |
Construction process of rigid steel structure housing
1. Design and planning stage
Demand communication: determine the building purpose, area, budget and local specifications (such as earthquake resistance level).
BIM modeling: optimize node design through three-dimensional modeling to solve the conflict problem of water and electricity pipelines in advance.
2. Factory production stage
Steel processing: laser cutting and automatic welding ensure the accuracy of components, and surface sandblasting enhances anti-corrosion adhesion.
Quality inspection system: ultrasonic flaw detection detects weld quality, and a third-party agency issues a mechanical properties report.
3. On-site construction stage
| Steps | Contents |
|---|---|
| Foundation construction | Independent foundation/raft foundation pouring, pre-buried anchor bolts (error ≤ 3mm). |
| Main assembly | Lifting steel columns → installing steel beams → laying floor decking → welding nodes (full penetration welds). |
| Enclosure system | Installation of exterior wall panels (ALC panels/metal curtain walls), roof colored steel tiles, and filling of rock wool insulation layer. |
| Interior decoration and equipment | Dry construction of walls and floors, integration of water and electricity pipelines, installation of doors and windows and smart home systems. |
