Is there an on-line resource for lumber weights...

Thanks.

I was looking for a lumber company/yard's resource with a table for finished/dried products. I found various woods with moisture contents in board feet etc. which is useful, but I haven't been able to find much for Pressure Treated ACS, Glulam, etc.

I know that you can call Menard's, etc. and they have weights on their computers, but I was just wondering if someone knew of a link that had all this good stuff in a tabular format.

I should've been more specific. Very interesting posts. Thanks.

• wood calculator

Ball park weight;

Pine = 30lbs/cft

Oak = 38lbs/cft

Thats all I can remember.

Good ballparks. A lot will depend on species and also moisture content. For instance, northern red oak comes in around 41 lbs at 12% moisture content (air dried, most places other than Arizona) and 46 lbs at 24% moisture content. Pines (Ponderosa) will be more like 28 lbs (12%)and 29 lbs 24%. Greener (wetter) wood will raise it substantially. This comes from the USDA Forest Products Handbook.

Green would be about 1/2 more? Or?

How about quoting some of the more common woods.

And is 24% about 1 year of field air drying?

Green moisture content will range up to 40% heartwood and 148% sapwood for pines. Red oaks are 80% heartwood and 70% sapwood.

More common woods? Ironwood isn't listed. LOL Common for Va would include black walnut at 36lbs(12%) and 38lbs (24%). Hickories at 42lbs and 46lbs. Black locust at 48lbs and 51lbs. Tulip poplar at 29lbs and 32lbs/cu ft.

Going back to red oaks, if it's really green, like up to 80% moisture content, we're talking 68lbs/cu ft. Ponderosa pine at 140% sapwood goes up to 60lbs/cu ft. There's a huge variation. Water ain't light.

Hope that satisfied your curiosity. I can go on, and on, and on.... Probably way more than the original poster wanted to know.

I rescued the son of a friend who had a trailer full of sopping wet pressure treated pine push him off the interstate, backwards. His little Toyota pickup just wasn't up to the job. Not sure just what that pile weighed, but my guess was in excess of 2 tons. I have a pretty good feel for my deuce-and-a-half. He was really lucky to have survived the experience. And continued to claim that the trailer (single axle) wasn't really overloaded. Yeah, right...

Ya I should have made myself more clear as I was talking about wood in log form for the 24%/yr ?

The green weights were more than I thought.

The black walnut was also a shocker. I thought it would be in the high 40's.

Thanks for posting the numbers.

Oh, that kind of common... Now we're on the same page. I look at trees and see boards. Firewood is what doesn't make it into boards.

24% wasn't anything but a number I grabbed for comparison. Trees don't do much drying until they're cut up. 24% won't happen until the log's been cut up (slabbed or split) and has sat for awhile.

Back to red oak. I just checked the one I was sawing. Dead 5 yrs, log ends exposed for almost 2 yrs, untreated. My moisture meter only goes up to 30%, which isn't anywhere close to measuring the log. Rough guess is maybe 40% moisture content. That means my 6"x24"x16' board is around 800lbs (16cuftx52lbs), headed down toward 670lbs (at 12%). When it was still growing, it would have been more like 1100lbs (70lbs/cuft). I'm not man enough to grab my end and go. That's why they make hydraulics. Need a board?
