does new untreated lumber get damaged by rain before you can finish your progect, such as shed,?
Answers:
No, over the course of rough framing a large house, we can get rained on quite a few times. As long as the lumber has time to properly be dried out before the interior wall covering goes on, it doesn't cause a problem. With a utility shed, I doubt you'd even use an interior wall covering, so you should be fine.

You project isn't ruined just because the frame got wet. Some new lumber, such as Doug Fir, is frequently wet when purchased. When lumber dries, it tends to twist and bend, sometimes dramatically. So what's important is securing it in place and finish your project as soon as possible, before the lumber starts to dry and warp. Once anchored securely, it won't go anywhere.

no worries. your fine. in my 36 yrs of const. ive yet to have to start on over because of rain.
no. however, lumber will twist after it dries. and prolonged exposure to the sun. if it is secured it will minimize the warping and twisting. the floor system will remain relatively straight, but the studs can warp. if you have a stud that is bowed or twisted, cut a wedge in it where the bow or twist is worse straighten it and add a stud next to it. structure wood (osb) will swell along the seams and in extreme conditions begin to deteriorate, so cover that up as quickly as possible.
