Square Circle Formwork Circular Column System is one of our most popular patented products which like our panels, are custom designed and manufactured specifically for the columns on your project.

The Circular Column forms are manufactured using film faced plywood sheets which have been moulded to a specific diameter of the customers request. These are then sealed shut using our steel belt at various levels around the column as required. Our Circular Column forms come in a wide range of heights and diameters depending on the customers needs. Our sizes are limited by your requirements. From 10000mm heights or 4200mm diameters (Or taller and wider), we are able to create the form you require.

The circular column panels arrive on site in either two semi circular pieces (For heights up to 3000mm and diameters up to 1550mm) or in multiple pieces (For heights above 3000mm and diameters bigger than 1550mm) which can be quickly assembled by 2 workers with zero cutting required. When poured and cured the forms can then be disassembled and moved for their next pour on the job and if required heights cut to fit beams or smaller heights as the design changes across the project.

Suitable for both a pouring up and down method of construction. Able to accommodate a wide range of setting up methods to suit the preference of the customer. The quick assembly method, multiple uses and high level of flexibility of our circular column forms has seen our customers save time and money across in many areas of their projects!
