Seperatation under steel bottom plate

There should be a separation layer between the bottom plate of the steel framing and the timber subfloor. Just needs a simple layer of DPC (damp proof course).

Fixing frames together

Frames are stood and connected using self-drilling screws that we usually provide. We find a drill torqued to the correct setting works better than an impact driver for drilling the screws. Screws are generally placed every 600mm minimum, two side by side, use discretion.

Bracket fixings

There are several different off the shelf options available depending on design and application. Self drilling screws can be used to screw off. Offen the roof connection will need these hold downs.

Bracing

Bracing straps are needed to be screwed and tightened to the outside of the framing. Should be added where possible to avoid openings on walls and roof. Keep an eye on plumb and level when tightening.

Packers

As seen in image above timber packers / wedges can be made up to fill and support a gable roof/wall connection for example. Timber is screwed in place and strapped down.

All this hardware is usually on the self on any hardware store. Refer to Mitek or Pryda for more detail.
