Need a stand-alone way to support an outdoor LED display? This free-standing support structure was designed and engineered to use its “self-weight” for stability. No external guy wires or ballast are required to meet a 30 MPH wind rating with the screen at 30′, 35 MPH at 25′, and 40 MPH, at 20′. The bare structure is good in winds up to 60 MPH. Higher ratings can be achieved using concrete blocks, water-barrels, etc. We use a weather station (you can see it sticking up from the top of the structure) to monitor local weather conditions, as well as a weather monitoring service to provide real-time data, alerts, and recommendations to our team on site. The engineering firm that certified the structure provided an operations and high wind action plan which we follow carefully to ensure the safety and reliability of the structure. If weather conditions are expected to exceed the safe operating criteria of the structure it must be lowered to the ground, (which is done with the press of a button) and in certain cases the LED tiles removed and the area cleared of all personnel and audience.
