,Prefab Steel Frame House
,Steel Frame Construction S235JR
- High Strength: Steel has high strength and strong load-bearing capacity, making it suitable for large-span and high-rise buildings.
- Lightweight: Compared to concrete, steel has a higher density but even greater strength, resulting in lighter structures and reduced foundation loads.
- Good Plasticity: Steel exhibits excellent plasticity, allowing it to withstand significant deformation and offering superior seismic performance.
- Good Toughness: Steel maintains good toughness even at low temperatures, making it suitable for cold environments.
- Fast Construction: Components can be prefabricated in factories and assembled on-site, shortening construction timelines.
- Eco-Friendly: Steel is recyclable, reducing construction waste and aligning with environmental sustainability.
- Good Sealing Properties: Welded steel structures provide excellent air and water tightness, making them ideal for containers and pipelines.
- Poor Corrosion Resistance: Steel is prone to rust and requires anti-corrosion measures.
- Poor Fire Resistance: Steel loses strength at high temperatures, necessitating fireproofing treatments.
