RAL 5011
Steel Blue
RAL 5011 Steel Blue is a very dark navy blue that evokes the color of tempered steel under low light. This commanding shade is specified for heavy industrial applications, structural steelwork, and formal architectural elements where a deep, authoritative blue is needed. Steel Blue provides excellent corrosion concealment on ferrous substrates and is commonly used for bridge components, structural columns, and heavy machinery frames across European infrastructure projects.
