Alu Skydeck Formwork Strips Slabs In 48 Hours While Props Keep Curing Below

Alu Skydeck is an aluminum panelized slab formwork system built around a single defining feature — the drophead. When struck with a hammer, the drophead lowers the formwork panels by 60 mm while the props remain fully loaded, supporting the curing slab. Panels are free to strip and rotate to the next floor within 48 hours, while the concrete continues curing undisturbed. For multi-story construction where floor cycle speed governs the entire project timeline, this is the competitive advantage.

• Pour phase: Drophead locked in raised position — beams and panels form a level, continuous soffit
• Strip phase: One hammer blow releases the collar — beams and panels drop 60 mm, freeing them for removal
• Cure phase: Props remain fully engaged, supporting the slab at full design load for the complete curing period

Panels, beams, and dropheads move to the next floor while props stay in place. This eliminates the trade-off between early stripping and structural safety — both happen simultaneously.

A 15 kg panel is handled by one worker — no crane, no trolley, no waiting. The entire system ships in compact stacks, a major logistics advantage for sites with limited laydown space.

• Standard configuration: Slab thicknesses up to 30 cm at standard prop spacing
• Reinforced configuration: Slabs up to 95 cm with closer prop grid and heavier beams
• Platform live load: 150 kg/m² during construction
• Drophead capacity: 20 KN per unit — verify prop grid against slab dead load

The system is most efficient for flat slab construction with regular, predictable prop grids.

• High-rise residential (★★★★★): Repetitive floor plates maximize early stripping value
• Commercial office towers (★★★★★): Large open floor plates suit panelized grid layout
• Parking structures (★★★★): Consistent bay dimensions within system capability
• Industrial and warehouse (★★★): High headroom and large spans may require supplementary shoring

• Over-tightening props before pour — props should be snug, not preloaded; over-tightening lifts beams off dropheads
• Delaying the first strike — dropheads release cleanest within 48–72 hours; fully hardened concrete grips panels tighter
• Neglecting drophead maintenance — concrete splatter accumulates on the release collar; clean after each use
• Exceeding max prop spacing — too wide a grid for the slab thickness risks excessive deflection

Alu Skydeck separates formwork from falsework mechanically — one crew strips panels while concrete cures. For high-rise developers where floor cycle time is the schedule governor, the drophead makes a 5-day floor cycle achievable.
