Excellent. Got a strong strap at the corners including a good metal ring in each one. Strong enough to be stretching with a pulling wire usually using to squaring gates in a wire fence. Also are strong enough to support good amount of wind and water probably snow pressure.  I recommend a 100 for decks, patio or even for some partys out side the house. Only thing I believe its should have some metal rings at the center due to the length of sail tarp.
