  Canadian sizes  
Metric bar designations represent the nominal bar diameter in millimeters, rounded to the nearest 5 mm.

  European sizes  
Metric bar designations represent the nominal bar diameter in millimetres. Bars in Europe will be specified to comply with the standard EN ****0(awaiting introduction as of early ***7), although various national standards still remain in force (e.g. BS ***9 in the United Kingdom).

  Australian Sizes  
Reinforcement for use in concrete construction is subject to the requirements of Australian Standards AS********9 (Concrete Structures) and AS/NZS********1 (Steel Reinforcing for Concrete). There are other standards that also apply to testing, welding and galvanising. The designation of reinforcement is defined in AS/NZS********1 using the following formats:
  Bars  

Shape Code	Yield Strength (MPa)	Ductility Class	Nominal Diameter (mm)
D - Deformed Bar	**0 MPa	N - Normal	*0
R - Round Bar	**0 MPa	L - Low	*2
			*6
			*0
			*4
			*8
			*2
			*6
			*0

 

• Examples:
• D**0N*2 is deformed bar, **0MPa strength, normal ductility and *2mm nominal diameter - also known simply as "N*2"
• R**0N*0 is round bar, **0MPa strength, normal ductility and *0mm nominal diameter - also known simply as "R*0"

 
Bars are typically abbreviated to simply \'N\' (hot-rolled deformed bar), \'R\' (hot-rolled round bar), \'RW\' (cold-drawn ribbed wire) or \'W\' (cold-drawn round wire), as the yield strength and ductility class can be implied from the shape. For example, all commercially available wire has a yield strength of **0MPa and low ductility, round bars are **0MPa and normal ductility, etc.
