Optimised beams are perfect for portal frames

Glassworks portal frame3

Every day, you probably use a product that has been manufactured or stored in a portal frame building made by STELTECH®. Portal frame buildings are everywhere, all over New Zealand.

A typical portal frame building has tapered columns and a tapered haunch section leading to parallel rafters. Using a column or central spine often results in a tapered apex section.

Probably the tallest building that STELTECH® has helped construct is the Recall building in Penrose, Auckland. It was built by Haydn and Rollett to be used for document storage as part of Recall’s nationwide service.

In 2010, we also provided portal frames for the new Countdown Supermarket in Manukau City, as part of their nationwide upgrade. Grayson Engineering pre-formed the fabrication and erection, a task made more challenging by the inclusion of an underground car park. This meant that no heavy lifting equipment could be placed inside the build.
