Reusable Aluminum Formwork System Modular Metal Formwork System For Tunnel And Bridge
The Aluminum Formwork System is a complete, modular shuttering solution designed for the rapid, repetitive construction of cast-in-place concrete structures, particularly high-rise residential towers. It replaces traditional timber and steel forms with lightweight, high-strength aluminum alloy panels and a unified support system, enabling monolithic pouring of walls, slabs, beams, and columns.
- Exceptional Strength-to-Weight Ratio: Fabricated from 6061-T6 aluminum alloy, the panels are remarkably lightweight (approx. 23 kg/m²) for easy manual handling, yet offer a design concrete pressure capacity exceeding 60 kN/m².
- Rapid Cycle Time & High Reusability: The simple pin-and-wedge connection allows for quick assembly and stripping by a small crew, achieving a typical floor cycle of 4-7 days. The system can be reused over 300 times with minimal maintenance, offering outstanding long-term economy.
- Superior Finish & Dimensional Accuracy: Precision-extruded components ensure tight joints and minimal grout loss, producing smooth, high-quality concrete surfaces that often eliminate the need for plastering, saving time and material costs.
- Material: Primary alloy 6061-T6, yield strength ≥240 MPa
- Panel Thickness: 4 mm face plate with 65 mm deep ribbed frame
- Standard Widths: Modular sizes from 100 mm to 600 mm
- Surface Treatment: Mill finish or optional powder coating for corrosion resistance
