Circular Formwork

A circular steel formwork system for curved wall construction.


Circular Formwork


Each Panel weighs 438 Kilos (2m x 2.25m) and can easily be lifted stacked in twos thanks to the unique aligning and plumbing mechanisms the system has to offer.

This is not possible with any other steel faced panel system due to the weight - but BIRA is only the same weight as a regular plywood shutter of the same dimensions.

When the concrete is poured the joint in the height is extremely tight thanks to the aligning wedges, so no grout loss occurs.

The feet on the pans allow the formwork to sit on the ground with ease as it enables you to adjust the panel level to suit any varying ground conditions.
