To give cautionary warning to passersby that a construction area exists, mark the area with the "Construction Area" safety sign. This danger sign is best used indoors and outdoors as four material options, aluminum, polystyrene plastic, fiberglass, and adhesive vinyl, are specifically made to withstand various environmental elements. It's also resistant to weather, moisture, and corrosive conditions, making this safety sign long-lasting and economical. For aluminum, plastic, and fiberglass materials, this safety sign has pre-drilled mounting holes and radius corners for easy mounting, while an adhesive vinyl has a strong adhesive backing that sticks on most dry surfaces.
