Prefab Steel Frame Structure Buildings

Prefabricated steel frame structure buildings are assembled on-site using steel beams, columns, and other components that are prefabricated in factories. Their features include fast construction speed, as steel components are prefabricated in factories and can be easily installed on-site, significantly shortening the construction period; high cost-effectiveness, as they save materials and labor costs compared to traditional construction methods, and have lower maintenance costs; high strength and light weight, capable of bearing large loads while reducing the burden on the foundation; superior seismic performance, as the ductility and plasticity of steel enable it to effectively absorb and dissipate seismic energy; and flexible design, adaptable to various building requirements, allowing for complex designs and large-span structures. 

Prefabricated steel frame structure buildings are widely used in multi-story and high-rise buildings, such as residences, office buildings, schools, hospitals, and industrial plants, providing efficient, economical, and environmentally friendly solutions for the construction industry.

Q&A

Q: What are the differences between prefabricated steel frame structures and ordinary steel structures?

A: The components of prefabricated steel frames are standardizedly produced in factories and then assembled on-site, which makes the construction more efficient and precise, and reduces on-site pollution. Ordinary steel structures may involve some on-site processing steps, which are more flexible but have a lower degree of industrialization.

Q: Are steel structure buildings more expensive?

A: The initial material cost is higher than that of concrete structures, but through shortening the construction period, reducing labor, lowering maintenance costs in the later stage, and having a higher recyclable value, the total life cycle cost may be more advantageous, especially for projects with tight schedules.

Q: How are sound insulation and thermal insulation issues addressed in steel structure residences?

A: Usually, a "steel frame + composite wall" system is adopted, with rock wool, glass wool and other thermal insulation and sound insulation materials filled inside, or with ALC boards or decorative thermal insulation integrated boards hung outside, to meet the comfort requirements of living.

Q: Can prefabricated steel frames support personalized design?

A: Modular design can flexibly combine space units, but it requires detailed design and type approval in the early stage. For complex shapes, BIM technology should be combined to optimize nodes, which may increase costs and construction difficulty.
