The versatile structures are manufactured from solid timber and galvanised steel to minimise corrosion and are said to be ideal for strengthening flooring and roofing structures. They are also capable of achieving floor spans of up to 10 metres due to the stronger/stiffer structure and roof spans of up to 20 metres with most sheet roofing materials.
Multinails new steel/wood joist system.
The robust SWJs can carry weights from 3kPa to 5kPa, and they utilise a Multinail patented ‘dry welded connection’, a steel web connected to the timber top and bottom chords that enables a variety of standard and specialised connections to be made.
Suitable for large spans and heavy loads in residential, commercial and industrial floor and roof structures, the SWJs are manufactured offsite, delivered when required, and designed to be simple and efficient to install. ■
