Construction Notes
The steel fence posts are cut to the proper length, the short pieces are welded on the ends to form additional tread rails, or are used for legs.
The ¾-inch-diameter rod is cut into short pieces and inserted into the ends of the 1-inch square tubing - the rod is easier to bend and makes for a stronger weld.
The 3/8-inch-diameter rod is slipped through the ends of the chain-link fence material and used to stretch and hold it tight. A short piece of the flat bar is bent and welded at the center of the lowest and highest point of each half of the ramp to add additional strength to the rod. The ends of the rod are finally welded to the inside of the 2-inch square tubing.
The flat bar is bent at the proper angle on each end and welded to the 2-inch square tubing to provide lateral strength, additional tread strength, and to hold the chain-link fence in place.
Steel angle iron (2 by 2 inches) could be substituted for the steel fence posts. They would also be welded on the ends to the 1-inch square tubing with the point of the angle facing up.
