The manufacturing process also creates an attractive, smooth off steel form concrete finish under quality controlled conditions.
The hollow core makes Rocla® Building Columns up to 30% lighter than solid columns. The hollow core allows services to be run along it length and can also include access block-outs.
Rocla® Building Columns can be manufactured in lengths up to 24m, reducing joints and simplifying alignment. Connection at intermediate floors and to the other building elements can be detailed in the design. Work with Rocla's team of engineers to satisfy your needs.

Features & Benefits
Rocla® Building Columns can be installed in minutes allowing the next stage of construction to proceed. No waiting for formwork, scaffolding, steel fixing, concrete pumping, curing, formwork stripping and surface patching.
Our building columns are high in strength because they are made of reinforced concrete (65MPa min) but also they have a smaller footprint, leaving more valuable floor space.
There are a range of cast-in components and options including:
- Block-outs for building in beams, floors, access
- Starter bars or barrel connectors at the base
- Ferrules at teh top and/or side walls
- Hole formers
Rolca® Building Columns can be designed for use as fully structural columns, permanent formwork, or as self-supporting permanent formwork. Columns are suitable for high rise, commercial/industrial, infrastructure and residentail applications.
