High-Strength Prefabricated Multi-Story Steel Structure Buildings
Multi-story steel structure factory buildings, warehouses, and workshops designed for fast assembly and industrial applications.
Product Overview
Industrial buildings with 2 or more stories using steel as the main load-bearing system, featuring rapid assembly capabilities.
Structural Composition
- Steel columns + steel beams + steel frame / frame-bracing system
- Profiled steel sheet concrete composite floor slabs
- Typically 2–8 stories with floor height of 4.5–6m
- Column grid spacing of 6–12m
- Floor live load designed at 5–15 kN/㎡
- Compatible with light/medium-sized cranes
Main Structural Solutions
- Pure Steel Frame: Ideal for 2–3 story light industrial/electronics factories with uniform loads
- Steel Frame + Cross Bracing: High seismic and lateral stiffness, suitable for 4–5 story machining and storage buildings
- Steel-Concrete Composite Structure: Steel columns + steel beams + thick composite slabs, offering excellent stiffness and low vibration for precision instrument workshops
