Rollformers 2000 Ltd provide rollformed galvanised steel studs and track to meet the requirements of the building industry for lightweight, strong and versatile steel wall framing. All studs are manufactured in accordance
with NZS/AS 1397-1993 and are able to be used in fire and sound rated situations up to a height of 7.2 meters. Please refer fire rated stud section for relavant information.
Rollformers steel stud and track are intended for use in the construction of non-load bearing walls, both interior and exterior. It is crucial to the performance of the product that the loads applied do not exceed the capabilities of the product. To avoid excessive wall movement or plaster cracking do not exceed the deflection limits given in AS/NZS 1170
For requirements over and above this please contact Rollformers technical department. Rollformers manufacture stud in nominal widths of:
51mm, 63.5mm, 75mm, 89mm, 92mm, 150mm
The following BMT are produced as standard:
0.55, 0.75, 0.95, 1.15
Please note 1.15 can only be achieved in 89mm stud and above only.
All studs have a 34mm face width. Both faces of the stud have a knurled finish, which will assist in the installation of the product by resisting screw slipage and providing additional holding power. Stock lengths are available from 2.4m to 9.5m or for non standard or special requirements contact the team at Rollformers now.
Steel stud track sections provide a friction fit for studs when installed in the tracks. This serves to hold the studs in position untill the appropiate lining board is installed, but in addition provides a slip joint to allow
movement in the structure. Note: Lining board should not be screwed to the track for this reason unless specified by consulting engineers.
Standard Track – Nominal 32mm Flange
Deflection Head Track – which has a 50mm Flange
General steel stud installation where walls are lined both sides, the standard tracks will be fit for purpose. Where the consulting engineer has indicated the use of a deflection head track a typical application for this track would be under a concrete slab or where the wall height exceeds 4800mm. There are no specific requirements for isolation of track sections from the concrete slabs unless specifically stated.
Track sections are standard lengths of 3000mm and should be fixed at intervals of no greater than 600mm centres. Initial fixings should be placed within 100mm of either end of the track section.
