Product Description
Steel Cross-Shaped Columns in Modern Construction
A High-Performance Structural Solution
1. Structural Configuration
Cross-shaped columns (cruciform sections) are fabricated by welding four steel plates into a "+" configuration, combining the advantages of H-sections and box columns. Typical dimensions include:
- Flange width: 200-800mm (standard series: C200×200 to C800×800)
- Plate thickness: 12-40mm (Grade Q355B/Q460C)
- Fillet welds: 8-20mm leg length (AWS D1.8 Class CP)
Key components:
- Web plates: Main load-bearing elements (σ_max ≤ 0.8Fy)
- Flange plates: Enhance buckling resistance (λ ≤ 0.45√(E/Fy))
- Stiffeners: Horizontal diaphragms @ 1.5m intervals
2. Material & Fabrication
Base materials:
- Chinese standard: Q355B
- International equivalents: ASTM A572 Gr.50 (Fy=345MPa) / EN 10025 S355
Fabrication process:
- CNC plasma cutting (tolerance ±1.5mm)
- Submerged arc welding (SAW) with ER70S-6 wire
- Post-weld heat treatment (PWHT @ 580-620°C)
- Shot blasting to SA 2.5 cleanliness
