Round Tubes

Round Column 

Our round formwork for concrete columns are manufactured by a revolutionary spiral system patented by Consystex.

Our circular columns range from 160mm up to 1510mm diameter with no limits in height. Our round tubes are lightweight, have strong resistance against fracture and are flexible for various applications.

Each diameter offers options for standard, medium and heavy sizes depending on your required length and allows us to achieve work for the highest of columns. 

Our columns are designed for an easy setup. Consystex columns require minimal bracing, depending on the pouring method used, saving time and labour.



Standard: Up to 5000mm

Medium: 5000mm - 6000mm

Heavy: 6000mm - 9000mm

Diameter: 160mm - 1810mm

We can manufacture any length. Pink tubes can be ordered to exact mm. Columns can be marked so that they can be dropped straight in when getting to site. 

They can also be cut on site. 

The Wrap System

Consystex has developed the Wrap System for larger diameter columns greater than 1810 mm in diameter.


Our workers form columns by wrapping filament tape and the double ply around  lightweight polystyrene shapes.

The wrapping system allows us to form larger diameter columns with no height limit. This approach creates the perfect finish and is ideal for large construction and infrastructure.
