All Aluminum or Composite Panel Alu Skydeck Formwork System for Concrete Slab

Created on 07.06

Case Study: Panelized Aluminum Slab Formwork with Drophead Technology Enables 1-Day Early Striking in Post-Tension Construction

01. Technical Background

The Mattapan Station redevelopment project in Boston utilized the SKYDECK panelized aluminum slab formwork system for 20,000 ft² of structural slab construction – including first-level structural slab and second-level post-tension slab. The system was selected for its drophead mechanism allowing early striking while maintaining prop support for curing concrete.

02. System Specifications & Performance

Parameter
Specification / Result
System type
Panel slab formwork
Material
Aluminum with powder coating
Formlining
9 mm FinPly
Panel weight
35 lbs (approx. 16 kg) per panel
Area per support
3.45 m²
Slab thickness capacity
Up to 109 cm
Permissible platform load
150 kg/m²
Drophead stroke
60 mm (single hammer blow)
Engineering advantages:
  • Drophead mechanism – early striking is possible after just one day; a single hammer blow lowers the drophead by 60 mm, allowing panels and beams to be removed while props remain as re-shoring
  • Panel interlocking – panels lock in place without swaying, enabling unskilled workers to learn quickly
  • Low prop density – only 0.29 props per m², significantly reducing material inventory on site
  • Powder-coated surface – undercut panel edges simplify cleaning and maintain performance across multiple reuses

03. Applications & Suitability

Alu Skydeck is widely used for:
  • High-rise residential and commercial slab construction
  • Post-tension slab forming
  • Renovation projects with confined spaces (panel size allows hand-carrying through tight access)
  • Projects with repetitive floor layouts where fast cycling maximizes ROI
