Browse Forums Outdoor Living 1 Dec 27, 2013 5:08 pm Hi All, Im looking to construct a patio roof to cover a new deck I am building in my backyard. I want a single sloped surface back to the fence. What I don't want is to have any posts on the edge that is within the garden. It is probably easier to explain with a picture and this design from Nathan Burkett in Melbourne is exactly what Im after - he has used single, welded steel beams for this, wondering if anyone else has achieved it other ways or if not, where to go to get something like this done in my yard. http://nathanburkett.com.au/project/malvern-project-2/ Thanks for any possible advice Cheers, Re: Patio Roof Construction help needed. 2Dec 27, 2013 6:53 pm That looks great in the link Looks like hes used 200mm square hollow section, that would be pretty heavy im guessing 35-40kg per meter I reckon he has also bolted it to the concrete fencing and used a decent amount of concrete to secure this at the footing. I would work out how much you need in meters and how many sections, go to a steel supplier and get a quote. Then visit a powder coating workshop ask then for a quote to coat the colour you desire and also ask them to weld it together (not hard) if they are coded welders. Then you'll need to organise transport ( they will be a weird shape) and a crane or many strong hands to fit them in place. Im guessing 85% of the total cost of this project will be the price of the steel Steel is really, really expensive so maybe going down to 150-100mm SHS might be an option. 8m of 200mm SHS should set you back $950 a length I did think about doing this at my old place but chickened out, you may also need council permission to errect this. Have fun Re: Patio Roof Construction help needed. 3Dec 27, 2013 7:25 pm Thanks for the reply Sunshine... Yes I agree - all the work on that website is exceptional. I am also considering timber as an option. Steel may just be to difficult, I guess I dont mind paying if the advantages ovver timber are so significant. I can always have posts in the yard just afraid of how they will interrupt what is a relatively small backyard. Lots of research to do - I will contact some steel yards as a starting point per your suggestion. Re: Patio Roof Construction help needed. 4Dec 27, 2013 7:35 pm The advantages of steel is you could achieve a large span, as with timber you would need bracing and coatings such as sealants or paint to prevent rot and weathering of the timber. Personally i think the look of steel looks very clean,and if powdercoated would last many years. What sort of dimensions did you want to cover? Thinking of getting this done over my spa as i don't like the gazebo huts that confine the spa Re: Patio Roof Construction help needed. 5Mar 30, 2014 10:11 am This is the style I am wanting to go for. I am happy to have exposed steel/corten beams. I am dreading getting a quote. The other option I am considering are those really chunky solid timber beams and running wire across the side 'wall' of one but still have the simplisitic look of the beams running across the roof. I'd be interested to see what your quotes come back as. Re: Patio Roof Construction help needed. 6Apr 30, 2014 6:02 pm Funny how so many people seem to have fallen in love with that design, including us. Not quite sure how we will alter the "roof" to be covered without affecting it's beauty though. Initially I thought it would be pretty trivial to build. Looking closer there are a lot of elements to consider. One being that fence, two being the heavy beams as Sunshine2013 mentioned. Onsite welding seems like it'd be easier? I was thinking the best way to build it would be to get a draftsman involved and give them the dimensions. They can use span tables etc to determine beam sizes. I'm thinking you'd need an actual builder to do the work, not a diy one. Please get a quote and let us know lol Re: Patio Roof Construction help needed. 7May 01, 2014 1:24 pm If you get decent drawings done a steel place would be able to weld it up in their factory then send it straight to be galvanized . A lot easier than doing it on site. Just get your measurements and angles right. Anyone with a bit of 'nous would be able to erect it and finish it off. Stewie Re: Patio Roof Construction help needed. 8May 11, 2014 12:56 pm HI Guys, O.K. having done quite a few like this, I can give you some advice. Firstly, get in touch with a business called Orrcon Steel or Onesteel, both are suppliers of the steel shs section. I believe that this is 180mm shs. Now, get a price on the steel as a regular pleb off the streets and then ask them if they can refer a small manufacturing / welding business, do NOT buy direct from the wholesaler, the manufactured price will be similar to the shs cost price if buying direct as a pleb off the streets. Now, in the picture from the previous listing, the timbers on top are not timber, they are aluminium. 50 x 50 timber is never straight and when it gets wet, its worse. Get in touch with Ullrich Aluminium or Alspec, Aluminium Specialties. Connecting the aluminium to the structural shs. The shs has connecting tabs welded to the top of it and the aluminium is screwed to it. If you are wanting to use timber on the top, you will need to reduce the distance between the steel supports. Joining the 2 together is exactly the same. Have a foot plate welded at each end of the shs, 1 to bolt to the wall or fascia and one to the concrete. simples. Extra support will be needed if connecting to the fascia. Allow $800.00 to $1200.00 cost price manufactured for each shs section and another $4.00 per kilo for galvanising. Aluminium for the top is relatively cheap in comparison. Buy end - caps for the aluminium. If you have the knowledge, go for it... steve@everlastpatios.com.au www.everlastpatios.com.au Re: Patio Roof Construction help needed. 9May 11, 2014 1:27 pm Another option, this one is much cheaper with very similar look.. Use 150 x 50 rhs aluminium section for the structure and 50 x 50 section for the roof fill. Buy woth from the suppliers listed above, when ordering, choose colour, the suppliers will have it powdercoated and will deliver to your address. Buy end-caps and some 150 x 50 internal joiners. Cut your rafters to length, do a 2 degree face cut both ends, where it meets the house and the other end, and do a 2 degree cut to the top of the upright section. If done right, when the upright/post is plum or level, the roof will be on a 2 degree fall. Find temporary stands to rest it on, concrete the post in later on. Once you know how far apart your main structure will be, mark it on the underside of the 50 x 50 section, also mark in the 50mm for the main structure. Where it will join to the main structure, pre-drill 2 holes.These will be used to join them together. Simply sit the smaller section over the main structure, and screw together. Use a small offcut piece as a spacer. Once the roof fill is on, plumb and concrete the posts in. Cheap and easy... steve@everlastpatios.com.au www.everlastpatios.com.au Re: Patio Roof Construction help needed. 10May 16, 2014 9:33 am I'm doing something like this - viewtopic.php?f=17&t=70232&p=1173810#p1173810 Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16140 Firstly the ableflex that has been installed needs (manufactures specification) a sealant cap over the top, preventing water draining down between the slab and the… 3 7780 If your patio is going to be 35 sqm then that's going to need Council Approval.
