DuraGal Flooring System®

Page Menu

DuraGal Flooring System® is a fully-engineered steel flooring system developed to provide a fire-and-termite-resistant, economical and easy-to-install alternative to conventional timber bearers and joists.

Easy to Install

DuraGal Flooring System® uses high strength C450L0 grade galvanized DuraGalPLUSTM ZB135/135 Hollow Sections. The sections are strong and lightweight making them easy to handle on site.

DuraGalPLUSTM ZB135/135 is easy to cut and drill, and best of all the system has been designed so that it simply screws together on site using a screw gun fitted with a hex head bit. The DuraGal Flooring System® features a range of speciality galvanized fittings designed to allow you to get on with the
job easily and quickly. Fast and accurate levelling of the floor using the adjustable piers during and after construction is a great feature.

Sheet flooring can still be attached in the traditional way using building adhesive and gun-nailing. Most reputable nail tool suppliers have hardened tipped nails to suit common nail guns to attach sheet flooring to steel joists up to and including 2mm thick.


Joists are typically 100 x 50 x 1.6mm with continuous spans of 2800mm and bearers are typically 150 x 50 x 2.0mm with continuous spans of 3000mm. Other sizes may be specified with differing spans subject to the floor layout and site conditions. Your DuraGal

Flooring System® distributor will be able to nominate the most economical sizes and layout upon receipt of the house plans.

Note: DuraGal Flooring System® requires independent engineering certification to determine compliance of site specific conditions with statutory requirements.
