"Constructed of high density Polyethylene, our A-frame signs are ideal for directing traffic in parking lots, construction sites or any other high traffic locations. Choose from one of our stock A-frame signs or create your own custom design. They can be internally ballasted with sand to provide extra stability and resist wind gusts. A-frame signs are easily folded and stacked for transportation or storage."^^<http://www.w3.org/2001/XMLSchema#string>
