1.Go Steel Garden Arch, 7'8" High x 4'5" Wide, Garden Arbor for Various Climbing Plant, Outdoor Garden Lawn Backyard

Can this hold a rose bush forever ?

is there a way to build this so it will not be as tall?

Is this strong enough to support vining vegetables? Squash, gourds, cucumbers?

Will the steel get hot enough from the sun to burn the plants that would go on it? I live in Texas and it can get over 100 degrees easy.
