Browse Forums Building A New House 1 Jan 30, 2016 10:49 pm Hi, I have been researching building our first house (new to the whole building process) and I was wondering if anyone has or has seen the use of duragal rhs/shs used in the design and construction of a house? I have seen it used in sub floors on houses built on sloping blocks, which I am currently looking into buyingand I think its a great idea. I'm a boilermaker by trade and I love the idea of using this to build my own frames (in my shed) and bolt or weld it all together on site. I have seen the material used for typical steel frame homes and I just don't like it, I think rhs or shs would be so much better and easier to pre fab off site. If anyone has any info I would greatly appreciate it. Cheers, Mick Re: Steel house construction 2Jan 31, 2016 7:14 am The only time I see rhs sections is for times when additional structural support is needed such as large spans ans cantilevers, Even then it is only used for the main structural elements with a timber frame, or lightweight steel frame used to form non structural walls. Some of the reasons for not using it are:
Difficulty in fastening plasterboard to thick section (can't use nails or self tapping plasterboard screws) Need for a crane. Difficulty of adjusting the frame to suit on site (some of the slabs I see aren't that accurate. The Harder You Try - the Luckier You Get !

My thought was because of the strength of steel compared to timber you would be not need as much material which would obviously save money. As for price comparison I don't believe there is a great deal of difference (the saving I would have with fabricating myself would more than be enough to offset the price difference. Fixing plasterboard I am not quite sure about yet but at most I would be using 2mm wall thickness (maybe even 1.6mm) and I don't think there would be a problem fixing plaster board to this. Crane work won't be a problem (nothing a few slabs won't sort out) Adjusting the frame work will not be an issue. The 'thermal bridge' I need to do more research on as I only first read about it recently. I read of someone using this method in Darwin I think. Might be more common with termites and cyclones etc. Cheers, Mick Hi I am wanting some opinions about the build of a steel shed I am going to get one about 4.5 x 2.5 m steel shed and the height will be about 2.3-2.4m high The one I am… 0 14470 You’re on the right track, wire brush in a grinder then a zinc rich epoxy primer then a top coat of some sort, like a waterproofing membrane.
