Prefabricated Steel Structure

Traditional Concrete Structure

Construction Efficiency

Components are standardized and manufactured in factories, requiring only assembly on-site. Construction is fast, the construction period is controllable, and it is less affected by weather.

Require on-site formwork, reinforcement binding, pouring, and curing. The process is complex, the construction cycle is long, and it is easily affected by environmental factors.

Structural Weight

Lightweight, approximately 1/3 to 1/2 the weight of concrete structures, significantly reducing the foundation load. Suitable for soft foundations or high-rise buildings.

Heavy, requiring high foundation bearing capacity, resulting in larger foundation works and higher material consumption.

Seismic performance

Steel has excellent ductility and toughness, effectively absorbing and dissipating seismic energy, with strong structural deformation capacity and superior seismic performance.

Brittle materials with low tensile strength, prone to cracking, crushing, and even collapse under seismic loads, resulting in relatively weak seismic resistance.

Environmental friendliness

Steel is 100% recyclable, generating less waste during production, and producing less noise and dust at the construction site, aligning with green building principles.

Concrete is difficult to recycle, becoming mostly construction waste after demolition, and the cement production process has high carbon emissions, resulting in a heavy environmental burden.

Economical advantages

While initial material costs are slightly higher, the overall construction period is shorter, labor costs are lower, foundation costs are lower, and maintenance is convenient, resulting in a significant cost advantage over the entire life cycle.

While has relatively low material costs, suffer from long construction periods, high labor demands, and expensive foundation treatment, meaning their overall cost may not be lower.
