• All signs are made from high quality, weather-resistant aluminum
• Carabiner hanger clips (included in your shipment) are stainless steel; selected in consideration of applications exposed to coastal salt air and cold climate deicing salt.
• It is recommended the sign and metal attachments be washed at least a couple times a year to wash away corrosive salt build-up and extend the life of the sign.
• Mounting holes drilled into the signs are stainless steel grommeted to provide added protection from weather-related wear. Grommeted holes are all .50 inches in diameter.
