Outdoor Coal Bin Construction

Outdoor Coal Bin Construction

PostBy: SteelerCoal On: Mon Jul 14, 2008 10:11 am

Hi. I'm in the process of planning my outdoor coal bin. I'm looking at building it with pressure treated 2x4s and pressure treated plywood. I want to make it 12' L x 8' W x 4' H. I will frame out the floor with PT 2x4s, 16" on center, with PT plywood as the flooring. Then construct the walls the same way, using all PT lumber. I'll then nail the walls down to the floor I framed. This will sit in my yard near my house (grass and dirt base). I'll cover the bin with plywood and tarp when it's filled.

Does this sound like it will work? Will the walls be able to support the weight of the coal, by just nailing them down to the framed floor? Or should I reinforce them somehow?

Also, any issue with having the bin sit directly on the ground?

Thanks for any comments you can give.

instead of 16" OC 12" would be better siding on the coal side,very a good plan

Thanks for the offer, but I burn rice coal. Mind if I ask how much you're paying for the Superior coal?

You'll need more support on the sides. Someone posted a photo of a wooden bin. I'll try to find it for you. I'd go pressure treated everything....or concrete.

I can't find it. Maybe someone remember where it is. They made triangles from 2 by fours that came out a couple of feet to support the sides.

Thanks. I did look through that thread, but I didn't really see much on free-standing outdoor bins.

I'm basically building a free standing rectangular box (12' x 8' x 4') with an opening on one end to access the coal, and no roof (that I'll cover with sheets of plywood and tarp). I'm wondering if I'll need reinforcement on the walls and how best to do that. Also, if having it set directly on the ground will be an issue.

Thanks for the link. But is that what I really need to do to build the bin? Space wise, there is no way that I can go with that type of support on the walls. I was hoping of a bit more of a "low profile". Visually, that bin looks like it would stick out like a sore thumb.

Maybe I'll just stick with bagged coal.

You don't need support like that, you can run cables inside the bin from one side to the other to hold it together or anything else really. That picture from that link I would suggest is well overbuilt. If you were stacking rock up inside it then you'd need that. Coal has about double the volume of rock.

You have to bind the sides together somehow, the open end of the U wants to spread. The top wants to splay out also. You have to hold it in place. The big blocks work well. Cables at 4' high would get in the way. You could dig a hole, provided you have a way to drain the water that will naturally want to go in also. A circle will work, think pool, good disguise too!

You can make the cables removable or use wratchet straps which would also be removable so it won't get in the way. At 4 feet high and the dimensions he has at most he might need two supports like those in the link. One on each side in the middle of the 12 foot length and that's only if you don't add the cables or something else. Truthfully even running something a like a 2X8 along the bottom would be sufficient or a 2X4 going across the top from one side to the other.

It's a nice bin CapeCoaler but it's way overbuilt for coal. That would be more suited for an industrial application for rock where you were stacking it as high as you could.

when making you floor frame put the 2x4 on end make your box frame run 2x4 in the middle for support Then lay your
Floor down nail or screw in down to the frame Take 2x4 make a L in each corner you will use 4 2x4 x 8ft cut them to 4ft
Put 2 or 3 more 2x4 4ft along both sides for support 1 in the middle for the back wall nail or screw the back & sides on for the front door Take 1x3x4ft go in 1 1/2 " from the 2x4 corners in the front screw the 1x3 inside one on each side wall to make a channel take a 4x8 sheet of plywood cut it in half 2ft use this for your door you can slide them up & down in the channel you can take one out when the coal gets low Now take some 2x4 and go across the top front middle and back screw them at the top of your corners and middel side support 2x4 now you will have more support for the sides they

will not move or bow out from the weight of the coal You can also split the front doors if you want to put a 2x4 in the middel on the front of bin you would make a T out of the 2x4 one flat against the bottom of the front floor frame take the other screw that to the first one on end like a T that way you can use that one to screw the 1x3 to make a 1 1/2 " channel for you doors use 3/4" Plywood That might work better being your bin will be 8ft wide You will have more support with that 2x4 in the middel only one side will be sliding doors the other will be solid you door still will be a 4x4 door Just a thought that's how I made mine been using it since 1996 it is under my front porch so it is out of the weather

The easest way to tie the two sides together is use a 8' 1 1/4" black iron pipe and two floor flanges.
A stick of pipe is 32 dollars and two floor flanges should be less than 5 dollars.
Screw a flanges on eithor end and put it inside the box adjust the flanges out until there snug againt the walls.
The floor flange will accept four screws this will stop the top of the bin from spreading.
