Frequently Asked Question

Do you have any question?

We will provide our screen mechanical drawing for your locally engaged structural engineers to evaluate your local zoning requirements and to determine your structure's ability to manage the requirements of the new display.

Our digital systems have been installed for many years where sometimes they have been pelted with rocks, bottles and cans. The durable face materials of our displays are resistant to such attacks. In extreme cases, where the displays have actually been heavily hit, the damage is limited to the area of the sign, requiring only modules to be replaced.

Our displays are built to withstand extreme weather. To protect against water damage, our display cabinets are sealed and the individual components are encased in a sealant, which prevents water from reaching the electrical leads and wiring. For protection against lightning storms, our digital technology is always installed with maximum grounding. In temperature extremes, ranging from as low as -20º to as high as 50º Centigrade, our digital technology is fully functional. We have hundreds of displays installed in coastal areas and hundreds more installed in areas of extreme cold or extreme heat. In hurricanes, blizzards and desert heat, we have real-world proof that our displays perform in all environments.
