Steel Mill
PPG1001-4 · Aqua Guard Undercoat
A sophisticated and calming shade, Steel Mill is a beautiful midtone grey blue. It evokes the quiet strength of industrial elegance combined with a gentle sense of permanence. Think of cool dawn light reflecting off polished metal or the steady serenity of an overcast sky. This colour brings a balanced atmosphere, offering depth without becoming oppressive. It feels grounded, reliable, and wonderfully modern.
Calmness, strength, balance, reliability, sophistication.
