Formwork propping and panels

SPI Expandadek Back to products

SPI Expandadek is a formwork soffit panel system. The panels are aluminium with a ply face that sits on an aluminium crown. The crown can be fixed on a special SPI prop or on SPI Speedshor, which can also include SPI Deck.


Expandadek panels can be used for slab thicknesses up to 450mm.


The panels are fitted with Bamboo Ply (bamboo has a longer life than timber). The panel frames are powder coated to make cleaning easier. Please refer to the Prop & Speedshor brochure for more details.
