1 in. x 2 ft. x 2 ft. Pine Edge Glued Panel Round Board

Yes, I made 10 plant dollies. I used 5 casters each--the 5th caster helps with stability. They were used outdoors in a condominium complex for the common area plants. This product has held up quite well. I stained and sealed them with a water seal. They have lasted over 5 years under rugged circumstances. It is time to make some more. My HOA bought some heavy duty plastic ones that only lasted 2 years.

You can stain this, but you should use a grain sealer to keep the finish from getting a blotted look. That is true of all soft wood and some hardwoods, suck as cherry.

Yes it could as long as the corner is a perfect 90 degrees. If its less than 90 it would work also but if the corner was, lets say 92 degrees, then you might only get three shelves to fit tightly.

No, the wood is composed of glued strips and is also to soft for weight bearing.

I am not sure, but I hesitate to use soft wood for food prep. For me, there is too much of a chance of food particles getting into the wood and I would not advise using this type of wood where you are going to have to wash and scrub it. Go to the lumber department and ask for a good hardwood, with a tight closed grain.

According to the website, your choices are 18" and 24".

I hope it doesn't warp. The grain alignment in the laminations appear to counter against warping. Be sure to seal the backside and especially the Circumferate edge grain to help stop moisture from being absorbed.

It's soft pine. Not typically used in outdoor wet conditions. A sealer would help but it's long term endurance outdoors is doubtful.

Yes, mine is outdoors and should last with the three coats of exterior varnish I used. If its going to sit in direct sunlight for eight hours a day? not so much.

That is what I used mine for
