The USGS has standardized on a basic design with three galvanized A-frame sizes. These are fabricated from A-36 structural steel and galvanized to A-123 specifications. A-Frame fabrication is welded wide flange I-beams sized per USGS specifications. Concrete anchor foundation design requirements are available. All necessary components are supplied including fasteners and concrete anchor bolts. Pipe or tubular section designs are discouraged because interior section corrosion inspection is impossible. These A-frame designs are for spans up to 1000 feet long.
