Head-to-Head Comparison Table between Steel Structure and Concrete Structure - Knowledge
Taking a 1000㎡ building as an example, the differences between steel structure and concrete structure...
1. Construction period (1000㎡):
Steel Structure : 3–4 weeks
Concrete Structure : on-site 6–12 months
2. Clear span without columns:
Steel Structure: Up to 40–60m
Concrete Structure: Typically 8–12m
3. Foundation cost:
Steel Structure:Light weight, 30–40% lower foundation
Concrete Structure: Heavy, deep foundation required
4. Service life:
Steel Structure: 50+ years with anti-corrosion
Concrete Structure:50–100 years
5. Recyclability:
Steel Structure: ~98% recyclable
Concrete Structure:Hard to recycle, demolition waste
6. Later expansion:
Steel Structure:Easy frame extension
Concrete Structure:Difficult, major demolition
7. Weather sensitivity:
Steel Structure:Factory prefab, minimal site work;
Concrete Structure:Curing depends on weather
8. Earthquake behavior:
Steel Structure:Ductile steel absorbs energy
Concrete Structure:Brittle cracking risk
