Timber and Steel Gates too heavy??
Hi All,
Hope I have posted in the right area? Well the time has come for me to make some gates for the end of my carport and side path. I've always wanted steel frame gates painted black with Merbau timber slats running horizontally. The gates need to be aprox 1800mm high and the pair of gates in the carport will about 1300mm wide each. The problem I have is the Merbau is going to cost a fortune.
Just the other day I was given this mass pile of Modwood (a great product) which I thought will be a great alternative. (See pic)
I was going to rip the wide boards in half to match the narrow ones. This stuff is 32mm thick! Wow! And it's heavy!!! I thought about making the gates from 30x30x2.5 SHS. Do you think this will be sufficient?
i guess the big issue in the back of my mind the whole time is the weight of these gates. I would use 4 x weld on hinges on each gate but I am worried if the brick work can hold such weight. I was thinking about using a heavy duty steel posts on each side which will then be bolted to the brick work at several locations down each side of each post. (To try to spread the load across more than one brick). Then do I use dyna bolts or Excalibur bolts?
This really has me concerned. I would appreciate any advise please.
Thank you,
Derek

if was me and I mean if was me building these gates, the first step would the size I could get a way with, height, length, swing direction and can I do three gates instead of two, and you have done that. you could bolt to the brick post and the wall of the house. but is the post core filled, is the wall just a brick veneer. which way will they swing into the back yard or towards the front of the house. with all these points taken in.
The brick work is a veneer, and not even. = support post will be needed with mounting points up the wall, this will give a straight line to hinge off, i would use the 30 x 30, just remember the brick wall of the house is only around 75mm thick its a veneer.
The brick post is not core filled and may be only a 12mm threaded rod going up in it as a tie down = support post will be needed with mounting points up the post, this will give a straight line to hinge two gates off
All gates swinging to the back yard to give the widest opening, so i would be mounting them to the backyard side of the post. 3 hinge points min on each gate
this is what I would do if it mine.

Thanks for your response. Yes I think the post is a simple brick veneer. I am worried about the gate pulling the bricks out due to weight. I will have a look down from top by taking roof off. Maybe I can fill it with concrete?

Not that I can really tell from the pictures if this would work, but could you put a dolly wheel under the leading edge of both gates so when swinging them, the wheel helps take the weight?
Just a quick thought.
Cheers

I think your 30x30x2.5 SHS is plenty strong enough once it's welded together and the timbers are attach, it should help brace the frame.. If you have any doubts about attaching the gate to your brick work, i would play it safe and concrete in something like 75x75x2.5mm or 100x100x2.5 duragal post, and hang the gates off of it.. I prefer to er on the side of to strong rather then to weak. You could always attach a wheel to the bottom of the gate to take some of the strain off the whole thing especially if you decided to attach it to your brick work. good luck..

The brick pier (not a post) is 230 x 230 brick, there is no hollow in the middle and I will lay odds on there is only a hoop iron strap in the pier to tie the pitching beam for the roof down but since where you are, is possible ther is a 12mm rod up the centre of the pier
For the pier use a 30 x 30 SHS but use 3 all pieces of Booker rod (threaded full length) 10mm dia and using a masonry bit drill through the joints between the bricks and nuts & washers each side or 300 long cup head bolts. The brick veneer is 110mm thick with 40mm to 50mm cavity to the frame.
For the house, use a 10mm x 200 bolt, cut the head off, bend cut end at 90 deg 30mm long, rake out joint in between bricks 30mm wide full depth of brick, insert bolt, rotate 90 deg, grout around bolt to eliminate side to side movement, mount post and tighten. Any of the propriety anchors will not hold in those bricks, they will have either 3 large holes per brick or 6 holes per brick.The person who never made a mistake never made anything
Cheers

Could you attach a jockey wheel to support the load?

I didn't want a jockey wheel if I could get away with it.
Thanks for for the advise rw build. So the bolts going into the house will hook behind the back of the brick? Do you think the mortar around the brick will be strong enough to stop it pulling out?
i guess if I have a few fixings point it should be ok.
