Stanley Canopies are produced from the same high strength, durable materials as our trailers - high grade aluminium for the framework and panels, and hot dip galvanised steel for the tailgate and hinges. They are designed and built to take the inevitable rough treatment they are subjected to in farming and construction environments. Tailgates are panelled either in galvanized steel weld mesh or 2mm thick aluminium with optional toughened glass window.
