GAOERJI offers high-strength steel-framed residential building solutions that integrate design, manufacturing, and global installation support, delivering exceptional seismic performance and rapid project delivery. As a source-manufacturing factory with many years of industry expertise, GAOERJI has implemented vertically integrated production to eliminate intermediary costs, enabling it to offer developers highly competitive ex-factory prices and rigorous, closed-loop quality control.
Steel-framed residential buildings are primarily used for high-end private villas, government-subsidized affordable housing projects, large-scale mining camp dormitories, and modular constructions in tourism and resort areas.
all the building components are precision prefabricated in the factory and only need to be bolted after arriving at the site, which can shorten the construction period by more than half compared with traditional concrete buildings and ensure the quick return of funds for the project.
the use of high-strength lightweight steel as the main frame, with excellent ductility and energy absorption capacity, under the action of seismic load only deformation and not easy to collapse, to ensure the safety of residents.
the self-weight of the steel structure is only about 1/3 of that of the traditional brick-concrete structure, which greatly reduces the requirements for the bearing capacity of the foundation, and can save significant earthwork and pile-based engineering costs under complex geological conditions.
due to the high strength of steel, the cross-sectional size of beams and columns is much smaller than that of concrete components, which can provide greater net use space under the same construction area and significantly improve the unit sales value of real estate developers.
the steel structure belongs to the category of green building, the main structure material recovery rate is high, and the construction site has no wet operation, low noise, no construction waste pollution, in line with international green investment standards.
components after shot blasting and multi-layer high-performance coating treatment, the film thickness of more than 120 microns, in all kinds of climate environment can maintain structural stability, reduce the later maintenance costs.
| Parameter name | Technical Specifications and Standards |
| Main structural material | Q355B or Q235B welded H-beams |
| Substructure | C-shaped steel, Z-shaped steel and channel steel supports |
| Connection method | High-strength large hexagonal bolt connection |
| Wall system | Glass wool sandwich panels or lightweight composite wall panels |
| Wind pressure resistance rating | It can withstand typhoons of level 12 or higher. |
| Anti-corrosion treatment | Hot-dip galvanizing or three-layer high-performance anti-rust paint |
| Floor decking material | Galvanized profiled steel sheet plus cast-in-place concrete |
| Sound insulation effect | The airborne sound insulation of the wall is greater than 45 decibels. |
It is suitable for large-scale residential development projects that pursue rapid capital turnover, and use the efficient construction advantages of steel structures to shorten the cycle from land acquisition to opening.
provide standardized housing modules that meet high seismic standards and can be quickly replicated on a large scale for affordable housing or post-disaster reconstruction projects.
It is suitable for supporting dormitories and office supporting buildings around large factories to meet the dual needs of rapid production and high-quality living environment.
It is suitable for the construction of boutique hotels or villas in ecological protection areas, reducing the damage to the natural landscape caused by on-site civil work, and realizing green construction.
before construction, the foundation shall be poured according to the anchor bolt layout provided by the GAOERJI, and the error between axis and elevation shall be strictly checked.
hoisting steel column and main girder in turn, preliminarily fixing with high-strength bolts, and final screwing after the whole span structure is corrected.
when installing wall panels and roof panels, ensure that the overlapping direction is away from the local prevailing wind direction, and use special waterproof gaskets to fix them.
after the delivery of the building, the water accumulation in the drainage channel should be checked regularly, and the coating of key nodes should be observed every 5 years to ensure long-term rust prevention.
