Sheet plywood weight and questions

Postby Rob Dines » Mon Apr 03, 2006 8:51 pm

Does anyone have weights for sheets of plywood? 1/4", 1/2", and also 3/4". Need this to get my overall weight so I can design the frame. Either sq. foot or sheet weight is good. Anyone have a good 1/4" exterior skin suggestion as ply is sorta expensive if exterior.
Thanks..

There have been many discussions concerning this matter. I just did a Search on "weight of plywood" and got this one: http://tnttt.com/viewto ... 26&start=0

Do a search and you will probably find a whole lot more info.
Chris :D

Rob,

I use this rough guesstimate...

3/4" plywood is 75#

1/2" plywood is 50#

1/4" plywood is 25#

You can extrapolate the rest...

Since you've given away the secret of Guesstimating Ply , how about telling us this .... That GVW thingie , that's including the weight of the trailer too that the cabin /TD sits on ,right ???? Those trailers have to be heavy , no ???

Yep, all weights include the chassis...

More info...
Net carrying capacity (NCC) determined by subtracting unloaded vehicle weight (UVW) from gross vehicle weight (GVWR) and includes fluids, options and cargo.

BUT...those weights are general guidelines and will vary with moisture content, type of wood in the ply, etc. I thought my 3/4" BC plywood for the floor felt heaver than 75 lbs, so I weighed it...87 lbs. It is made from yellow pine, which is heavier than spruce.

I see you Merkans still use the easy abbreviations.

The max weight of a British caravan (trailer) is its MTPLM - Maximum Technically Permissible Laden Mass!

And its 'empty' weight but with any options fitted is its MIRO - Mass In Running Order.

I think these are probably both Yurpeen terms, but decided on by non-English speakers - Yurp does have about 25 languages........

There are other quaint mercun acros that would apply to my build. So far, I've run up against situations best described as SNAFU, SUSFU, FUMTU, FUBB, TARFU, TOFU, but as of yet, I haven't made it to FUBAR, and hope I don't get that far.
