Pine and really cheap particle board. all the houses over here are made out of cement and the floors are cement too. then they put hardwood floors in. that is the only real hardwood available to me over here. I don't think that will make a real good stand.
When I moved over here a year ago a friend told me to bring a bunch of oak and walnut over here. He said that is is very hard to find. I'll have to find a mill that deals only with hard woods and I know that if I find one it will cost a fortune to buy wood.
So as to what I was saying before the Germans make steel stands and cover them in a type of particle board that is laminated, kinda like sauder furniture. It's not strong at all!
On the other hand the rest of the aquarium supplies that they sell over here are awesome.
Oh, I just thought of this. You can buy some plywood here but its thinner than 1/2" and not usable for covering a stand!
