90mm Wall Frames

Central Steel Framing's 90mm Framing is run from AXXIS® Steel for Framing using Howick FRAMA™ technology - so you know your framing is strong, straight, and built to last.

Get in Touch


90mm Framing is perfect for residential stud walls, mid floors, and roof panels. Commercial internal and external walls, mid floors, inter tenancy and fire rated walls. It also allows for higher R Value to be achieved where energy efficiency or extreme temperatures are a factor.


Frames can be designed using the following software Vertex, SFS, Quick series, Truss D&E, Tekla, and Howick Panel Software. Our preferred partners choose Vertex Software.

If you have a small project and want to have a go yourself, request a download of our free Howick Panel Software.

Alternatively, for projects large or small send your plans through via our enquire now section for a free quote. One of our detailers will be in touch with a budget price and to discuss your project.

90mm Framing is designed to be used with all other frame, joist, and truss profiles. We partner up with providers of these across New Zealand to deliver you a complete package.


Our 90mm Framing is manufactured from AXXIS® Steel for Framing and is backed by New Zealand Steel's 50-year durability statement. It is a hot dipped galvanised steel with a coating weight of 275 g/m2, in line with other common lightweight steel structural building products.

This gives good protection in most exposed internal environments, and for external use in moderate marine environments. Where used in a lined interior dwelling, a thermal break should be installed between the framing and the cladding to avoid thermal bridging.


Handling and Storage

90mm Framing should be kept dry during storage as water present between close stacked sections will cause premature corrosion. Once the frames have been installed onsite and the building is wrapped, apply a quick blow down of the upper frames to remove loose swarf and excess moisture. Also vacuum out of the bottom track before organising a pre-line inspection.

Where sections are exposed to salt spray but not rain washing, maintenance is required to remove any build-up of salt deposits on the surface.

Run-off from, or contact with, materials which are incompatible with zinc should be avoided.


90mm Framing is pre-punched and cut to length in our machine using machine files generated by the design software specifically for your project. Each stud, track or brace is cut to length and marked to a plan. It arrives on site either pre-assembled in our factory or flat pack cut-to-length ready for your builder to assemble. All you need is an impact driver and driver bit. We provide an easy-to-follow plan and the fasteners required to screw the pieces together. We recommend maximum wall dimensions of 3m x 6m for pre-assembled walls. For flat pack bundles the longest length is only limited by the available transport and handling facilities. Standard track and stud lengths can be run for commercial interior type walls if required, but we do recommend taking advantage of our design software.
