PLX Portal

The next generation in portal bracing is here!

A strong but lightweight timber bracing solution, the PLX Portal revolutionises building construction. A smart and sustainable alternative to heavy, hard-to-install and emission-intensive steel portals, the PLX Portal is proudly designed and manufactured in New Zealand by Prolam.

Innovative design
The PLX Portal is constructed from three glulam timber elements,   including Prolam’s trademarked PLX20 Beam – precision engineered from quality radiata pine reinforced with steel for increased load bearing capacity. The reinforced beam offers excellent spanning capability to deliver optimal design flexibility for architectural features ranging from large internal openings to garage and window bracing portals or anywhere you need bracing but only have a narrow wall space.

Unmatched Installation Ease
The beauty of the PLX Portal lies in its lightweight construction and the simplicity of its onsite assembly and installation. The timber lintel and legs can be cut to length onsite to suit your project, assembled using standard tools, and installed and fixed without the need for extra labour, specialised skills or equipment such as cranes.
