It's often said that a 16ga. 1x1" tubing is as strong as a construction grade 2x4. How is that - in a certain direction, with a certain structure to it? explain. Consider if you will a 4x8 platform that has a 3/4" plywood top screwed to a 1x1 box steel frame done in the same way of fraiming - certainly this wouldn't be as strong or we would have 1.3/4" thick platforms.
