Alright, someone is supposed to bring a 55 gallon tank by my house this weekend so I'm gonna start building my stand.

I'd like to use a slightly modified version of this:

Would it be ok to put the green screw strips on the outside? (if I don't I'd need to make my stand a few inches longer than the tank) Also, would I need to put upright beams in the middle to support it? It is 51 long after all.
