LVL beam support


Hi everyone,
For the past couple of days I have been looking through all kinds of literature to find out how much weight an lvl beam can hold.

Some of the live load specs I've read states that I must facor in 50psf for snow and 10psf for dead load. We don't really get all the much snow here. However after calculating how much weight per linear foot I will need to support :

50psf X 20'=1,000
10psf x 20'=200

for a total of 1,200 per linear foot. The only documentation that comes close to my 45mm X 600MM is dealing with KN and so on. All I have is a simple tin roof that I am supporting, not much slope, so I thought an lvl beam would suffice.

I have heard that lvl beams are crazy strong and such, but I cannot find one site that lays it all out for me. Any help on this would be very much appreciated.

just talk to the guys on the contractor desk at your lumberyard. they should have a engineer who designs floor and roof systems on staff or one on call

LVL beam support


if my math is correct in converting mm to inches you have a 1-3/4" x 23-5/8" LVL. most manufactuers require a 2 ply beam when you reach 16" in beam depth due to buckling (slenderness) of a tall single ply member.

kirk is spot on, take with the guys at your local lumber yard.

By lumberyard nobody meant Box Store btw.

Just wanted to save you from some potential aggravation.

I googled "lvl strength" and found tons.

A possibility...

Hehe... Menards carries LVL in stock. I love Menards.

But, you can always go pay more at a lumberyard if that's your thing. I'm sure the spec doesn't apply to Menards because they have a store that is big and box-like instead of small and expensive. :-)
