Steel Structure Homes

A steel structure residence, as the name implies, refers to a residential building whose main load-bearing components (such as beams, columns, floor slabs and roof trusses) are made of steel (usually hot-rolled H-shaped steel, cold-formed steel, etc.) and assembled by means of welding, bolt connection and other methods.

It Is More Than Just a "Skeleton": A complete steel structure residential system is a systematic project, consisting of the main steel structure, enclosure system (walls and roofs), equipment system (water supply, heating and electricity) and interior finishing system. Its core concept is the separation of the structural system from the enclosure and equipment systems, which offers great flexibility for design and renovation.

It Is Not a "Prefabricated Temporary Hut": The public often confuses steel structure residences with temporary buildings. In fact, modern steel structure residences boast mature technologies and strict standards. Their safety, comfort and aesthetics far surpass those of traditional brick-concrete structures, making them synonymous with permanent high-end buildings.

High Strength and Light Weight: Steel has a much higher strength than concrete and masonry, while its self-weight is considerably lighter (approximately 60% of that of brick-concrete structures). This reduces the requirements for building foundations, making it particularly suitable for areas with poor geological conditions.

Excellent Seismic and Wind Resistance Performance: Steel boasts good ductility and toughness, capable of absorbing and dissipating seismic energy through deformation. It is not prone to sudden brittle failure during earthquakes, truly achieving the goal of "no collapse in major earthquakes". This is crucial for regions with high seismic intensity.

High Precision and Stable Quality: Steel components are manufactured in factories with standardized and automated processes, featuring precise dimensions and controllable quality. This completely eliminates quality fluctuations caused by weather-dependent construction and manual operations at traditional construction sites.

Recyclable Materials: When buildings are demolished, steel boasts an extremely high recycling rate (up to 80%–90%). As a genuine green building material, it is fully aligned with the concept of circular economy.

Reduced Construction Waste: With dry construction as the primary method, on-site construction waste is reduced by approximately 80%, while noise and dust pollution are significantly lowered.

Resource Conservation: Clay bricks are no longer used, thus protecting arable land. Thinner wall structures effectively increase the usable floor area by around 5%–8%.

"Building Houses Like Manufacturing Cars": Components are prefabricated in factories, and on-site construction only requires assembly just like "putting together building blocks", resulting in extremely high construction efficiency. The construction period is shortened by 1/3 to 1/2 compared with that of traditional buildings. This greatly reduces capital costs and risks caused by weather conditions.

Steel structures can easily achieve large-span, large-space designs with no columns or few columns, providing unlimited possibilities for interior space layout and allowing residents to easily change the position of partition walls according to changes in living needs.

The main load-bearing components adopt cold-formed thin-walled C-section steel and U-section steel, with the wall thickness usually ranging from 100 mm to 150 mm. They are widely used in low-rise (1–3 stories) detached houses, villas and stacked villas, and have become the mainstream in the current civil residential market.

Frame systems are formed using hot-rolled H-section steel and square steel pipes, which are commonly used in mid-rise (4–12 stories) apartments and serviced apartments. They offer greater load-bearing capacity and larger space spans.
