Slab Panel Deflection

Aluplex Panels for Concrete Slab Casting | Tejus Centering India
Tejus Aluplex Panels are the ideal solution for efficient and lightweight concrete slab casting. Designed with modularity and ease of installation in mind, the Aluplex formwork system includes essential accessories such as crowns, tripods, props, pipes, couplers, and crown lock pins. Panels can be erected directly from slab corners and edges, simplifying setup time.
The core strength of Aluplex lies in its high-quality birch plywood with a plastic overlay, ensuring durability and excellent concrete finishes. For even higher repetition cycles, polypropylene glass fibre sheet panels are also available. The system includes specially designed filler (Gabdi) sections to efficiently cover odd slab gaps.
Lightweight, reusable, and built for high-rise slab formwork, Tejus Aluplex panels are trusted across India for cost-effective and high-performance slab centering solutions.

 Deflection -Slab Panel | Tejus Centering India
Tejus Centering offers precision-engineered aluminum slab panels (1800 x 900 mm) tested for structural deflection performance under varying slab concrete thicknesses. Based on structural engineering assessments, the panel system shows safe usage for slab thicknesses up to 450 mm.
Deflection values were measured for both the 1.8 m and 0.9 m spans. For 1.8 m length, deflections ranged from 1.84 mm (200 mm slab) to 4.14 mm (450 mm slab), staying within safe limits (L/325 standard). For the shorter 0.9 m member, deflection was minimal, between 0.14 mm to 0.32 mm—representing less than 12% of the allowable limit.
This performance confirms Tejus’ aluminum formwork panels are safe, reliable, and reusable for concrete slab construction up to 450 mm thick. Designed for minimal deflection and maximum durability, our panels meet site safety and efficiency standards for residential, commercial, and infrastructure projects.

Important Note | Tejus Centering India
The deflection calculations provided above are specific to the primary members of Tejus aluminum slab panels (1800 mm x 900 mm). Based on the test data and allowable limits (L/325), concrete slabs up to 450 mm thick can be safely poured using our Alu Panel system.
However, it is critical to ensure that the supporting system below—including props, beams, and staging—is designed according to the slab thickness and the height of the floor. Proper shoring and staging must be in place to maintain structural integrity and safety during casting.
