RAL 9017
Traffic Black
RAL 9017 Traffic Black is a standardized deep black from the RAL traffic color family, designed for consistent application across European road infrastructure and public transportation systems. This intense, neutral black is specified for traffic signal housings, road furniture, and transit equipment where a uniform, professional dark finish is required. Traffic Black provides excellent durability in exterior applications and maintains its depth even after years of exposure to UV radiation and urban pollution.
