Standard Thickness of Column Shuttering
The thickness of column shuttering varies depending on the material used (steel, aluminum, or wood) and the project’s load requirements. Below are the typical thickness ranges for each type:
1. Steel Formwork
- Standard Thickness: 3–6 mm (commonly 4–5 mm for Q235 steel)
- Load Capacity: Thicker panels (e.g., 6 mm) can withstand higher pressures (up to 60 kN/m²), making them suitable for heavy-duty applications like high-rise columns1219
- Reusability: Thicker steel formwork (≥5 mm) typically lasts 40+ cycles due to enhanced durability
2. Aluminum Formwork
- Standard Thickness: 2–4 mm1618
- Advantages: Lighter than steel but with lower load capacity; ideal for repetitive use in residential projects
- Reusability: ~50–100 cycles (depending on maintenance)
3. Wood Formwork (Plywood)
- Standard Thickness: 15–25 mm1626
- Limitations: Lower durability (reuse 5–10 times) and prone to moisture damage; used for low-cost or small-scale projects
Key Considerations
- Thickness vs. Performance: Thicker materials (e.g., steel) offer higher strength but require more handling effort
- Project Suitability:
- Steel: High-rise buildings, heavy loads
- Aluminum: Fast-paced residential projects
- Wood: Temporary or low-budget structures
