Construction Zone Signs
hdiv

SA-SO construction zone signs make construction zones safer for workers and motorists. Our construction zone signs are reflective .080 aluminum, and they’re made in the USA! SA-SO retro-reflective sheeting on signs increases visibility at night by reflecting light back towards the vehicle. SA-SO construction zone signs are specifically designed to alert pedestrians and motorists! Give drivers advanced notice of changing traffic patterns and help to improve safety and reduce accidents.
