The sheeting makes these signs obvious throughout the day and through the night. Our aluminum signs are for both indoor and outdoor use, but because aluminum is one of the commonly used metals that never rusts in any weather, it’s also used outdoors. Your reflective aluminum signs can be found with curved corners for protection applications along with pre-slots for even easier installation. You can even customize your warning signs by contour-cutting them in desirable condition. These characteristics contain a sturdy plastic key between two metal sheets.
