This is from Small Parts and they deliver their products, like this Aluminum 6063-T52 Square Tubing, ASTM B221, 1" x 1", 0.062" Wall, 72" Length in Tubes, very well protected from shipping damages and I have never gotten a damaged product and have received many orders in perfect condition.  This is an aluminum square tubing for building a light string fixture.  The light string can be stuck to the tubing with the adhesive back and held secure with tie wraps for assurance it will stay put.  Straight and true, due to the great shipping preparation taken by Small Parts.  I love these guys!
