4x8 Porch Beam
« on: July 06, 2008, 09:44:06 AM »
Having trouble finding anyone who supplies 4x8 beams.  Are there any alternatives to using this size beam on the porch?

You will probably not find the true 4X8 but rather the milled demensions of 3-1/2 X 7-1/2 or maybe they are 7-1/4 now.  If you want a true 4X8 it would have to be special order from a mill.  Haven't looked to see if Lowes or HD have them but any lumberyard can get them for you if they are not on hand.

I just searched Lowes from Washington DC to the Virginias and apparently this must be a special order as none indicated it being in stock.  I would give them a call and see if they can get it for you.  But you would probably have better luck at a local lumberyard.

 What exactly where you looking for then? A 4x8 , net 3 1/2"x 7 1/4" beam of either Douglas Fir or PT Pine should be easy as finding a 16 penny sinker , lumber yards , of any worth should have plenty / some in stock.

 So what exactly where you looking for ? Links in your local area ? Saw mills ??   What???

Like I said PEG, I'm looking for alternatives to using a 4x8 beam on the porch.  If it was easy as finding a 16 penny striker, I wouldn't of taken the time to ask the question here in the forum. 

If I knew I was going to get advice like "look in a lumber yard" I would of considered getting my plans somewhere else.

 My statements have nothing to do with John or his plan sales , I'm just a member of this forum like you.  I recieve no pay nor perks I do know John as we met at a  WW guild show  a few years ago.And live on the same island , about 40 miles apart. But I have really nothing to do with John or his plan sales.   

 If you can't find 4x8 lumber there are alternatives like LVL , Laminate veneer lumber, of LSL a stranded type beam stock , generally those are more expensive but care more load per inch of thickness. They also would be found at a lumber yard , have you checked with supplier in your area ? Which I guess would be Alberta, Canada ? Are you out in the bush? I just can't see how it could be that hard to find a standard D. Fir beam in Alberta.

 Sorry if I offended you in anyway  :-[

Was that a Full size 4x8, Curt as most times the size is nominal -- in name only - so the finiished sizes would be the 3 5/8 x 7 5/8 or so.

Do you think you could make a built up beam like 2 2x8's and a piece of plywood as we commonly do with the house main beams?

Sometimes we get kidding around here but I have met PEG personally and while he does kid around a bit , he really has the forum members interest at heart and I'm sure he didn't mean to offend you.

It is hard to get your attitude across on the 2 dimensional computer when you can't talk to someone in person so they can see you are kidding but good natured. :)

Sometimes it is easier to find a 6x6 and that can work fine on most porch spans. A 4x8 can also be built up as Glenn mentions.

Another easy option is to take the page of the plans into the lumber yard and ask them for a substitution. There are lots of engineered options and local materials that might be move available. A 4x8 is pretty common so they must have something else your local builders use instead.
