Ratings and reviews

Useful if you're inexperienced. Definitely not what you're looking for if you have a few years under your belt. I saw this advertised with a load calculator for joists and they lied, didn't have it. Plus the ads are too many to bare. Remember your formulas and just use a calculator.

it is really possible to develop any plan you want or need as there way it is from your mind
