Steel Structure House Building Characteristics
High yield strength main frame
Using Q355B grade H-beam, yield strength ≥ 355MPa. Compared with the traditional concrete structure, the section is smaller under the same load-bearing, and the use area in the sleeve is increased by about 6-10%.
precision precast production
All components are cut, drilled and welded at the factory with dimensional tolerances within ± 2mm. Zero welding installation on site reduces the structural risk caused by human installation errors.
Anti-corrosion treatment reduces maintenance costs
All steel components have been sandblasted and derusted at Sa2.5 level, and the surface is covered with 275g/m² hot dip galvanized layer or epoxy zinc-rich primer, which effectively prevents atmospheric corrosion and reduces maintenance costs by 80%.
Efficient thermal insulation enclosure system
The wall is made of 75mm thick PU (polyurethane) sandwich panel with low thermal conductivity of 0.024W/(m · k). Compared with 240mm brick wall, the overall energy consumption of the building is reduced by more than 40%.
Flexible Large Span Design
Supports maximum 60 m span design without mid-column. The interior space is not limited by load-bearing walls, providing contractors with a high degree of freedom in the division of units to adapt to various commercial or residential layouts.
Rapid construction cycle
Dry construction method is not affected by the season. Every 1000 square meters of Steel Structure House Building takes only 20 days to complete the main construction, speeding up the return of funds.

Steel Structure House Building Comparison Points
Compared with traditional reinforced concrete buildings, this Steel Structure House Building significantly improves the return on investment and reduces construction risks.
Shorten the project delivery cycle and reduce the cost of capital occupation.
In view of the long construction period of traditional buildings and the great impact of shutdown due to rain and snow, the overall delivery time is shortened by 40%-60% through 100 prefabricated production in the factory and only bolt assembly is required on site, allowing developers to enter the sales or operation period half a year in advance.
Solve the problem of high labor costs in developed areas
In view of the current situation of high hourly wages for construction workers in European, American and Australian markets, Steel Structure House Building adopts dry construction, which does not require a large number of masons and steel workers on site, reduces the number of workers on site by about 70%, and greatly reduces labor expenditure.
Improve the adaptability of the foundation and reduce the investment in basic engineering.
In view of the high cost of foundation treatment caused by complex geological conditions (such as soft soil and sloping land), the weight of steel structure is only 1/5 of that of concrete building, which significantly reduces the requirements for foundation bearing capacity, and the cost of foundation engineering can be saved by 20%-30%.
Steel Structure House Building Target audience
Residential developers and general contractors
Suitable for small and medium-sized residential projects seeking quick turnaround. Take advantage of the rapid assembly characteristics of Steel Structure House Building to complete the delivery of townhouses or low-rise apartments in a shorter cycle time, maximizing capital utilization.
Mining and engineering camps in remote areas
For temporary or semi-permanent living needs in inaccessible areas. Modular components are easy to transport in containers and can resist the harsh wind and snow environment in the wild, providing safe and comfortable staff quarters.
Government projects for affordable housing
Suitable for large-scale housing projects with limited budgets and the need for rapid resettlement. The standardized production process greatly reduces the cost of monomers and is a cost-effective solution to the housing shortage of Steel Structure House Building solutions.
Owners of private self-built houses
For individual investors who own land and want to customize their apartment. The large-span column-free design allows owners to freely plan indoor partitions, and the steel structure material recovery rate is 100%, which is in line with the concept of environmental protection and sustainable construction.
Instructions for use Steel Structure House Building
Calibration of embedded parts of foundation
When pouring concrete foundation, it is necessary to accurately embed anchor bolts of M24 or larger size. Use theodolite to control the bolt center deviation within ± 2mm to ensure smooth seating of steel column.
Hoisting of main frame
The steel columns and beams shall be assembled first and connected with 10.9 grade high strength bolts. Initial tightening shall be carried out first, and after the verticality deviation is adjusted to be less than H/1000, the torque wrench shall be used for final tightening and fixing.
Installation of secondary structure and support
Install roof purlins, wall purlins and tie bars. The support between columns (X-type support) and the roof horizontal support must be installed synchronously to form a stable geometric invariant system to prevent structural deformation.
Laying of enclosure system
Roof panels shall be laid from the eaves. Waterproof sealant shall be applied at the overlap between panels and fixed with self-tapping nails with EPDM gasket to prevent rainwater leakage.

FAQ And Contact Us
Welcome to our Frequently Asked Questions page. We have compiled answers to common questions you may have, hoping to provide you with clear and quick solutions. If you cannot find the information you need here, please feel free to contact our customer support team.
How long is the useful life of Steel Structure House Building?
The main steel structure is hot-dip galvanized or high-quality anti-corrosion coating. Under normal maintenance, the design service life can reach 50 to 70 years, which is equivalent to traditional concrete buildings.
Is this building able to withstand hurricanes or strong earthquakes?
Yes. Steel has extremely high ductility and toughness. Our design criteria are generally resistant to hurricanes above 120 km/h (12 wind) and earthquakes of magnitude 8, and the structure will not undergo brittle fracture.
How is the sound insulation effect of the wall?
Through the use of 75mm or 100mm thick rock wool or glass wool sandwich panels, with double-layer hollow glass windows, the wall sound insulation can reach 40-50 decibels, meeting the general residential and office mute standards.
What kind of daily maintenance does this kind of house need?
The maintenance cost is very low. It is recommended to check whether the roof waterproof glue and drainage ditches are blocked every 3-5 years, and repair and renovate the external steel components every 10-15 years as appropriate to maintain the best anti-corrosion performance.
Does Steel Structure House Building support custom design?
Support. We use Tekla Structures software for modeling and can customize the design and production to 100% according to the floor plan or specific dimensions (length, width, cornice height) provided by the customer.
What is the mode of transportation?
All components are packaged in pieces and designed for export. Usually use 1333.32cm high cabinet (40HQ) container transportation, a 40HQ can be loaded with about 150-200 square meters of housing materials (depending on the thickness of the wall).
Please feel free to contact us. We look forward to hearing from you.
