Steel bar is often painted at the ends. This is to Colour code the bar, generally by Steel quality (i.e. grade).
However, different suppliers tend to follow different colour codings. What one supplier paints blue, another will mark in green.
Time for a new standard perhaps - where colours are applied consistently by all rolling mills across the industry?
