Document Type and Number:
Japanese Patent JP2011104616
Kind Code:
A
Abstract:
To allow the steel grade and the diameter of bar steel to be discriminated easily.
The peripheral surface of the deformed bar steel 10 has a plurality of display regions 14A arranged along the axial line of the deformed bar steel 10. On each display region 14A, a steel grade discrimination mark 15A composed of a paint producing a color corresponding to the steel grade and a diameter discrimination mark 16A composed of a paint producing a color corresponding to the diameter are put. These steel grade discrimination mark 15A and the diameter identification mark 16A are different in at least one of a shape, a number, dimensions and an angle to the deformed bar steel.
