It can be difficult as a Civil Engineer finding the right steel reinforcement specification whcontractors on site will be happy with and is readily available. We summarised some of the most common reinforcement and rebar sizes along with their design properties

Reinforcement Size	Diameter (mm)	Cross-Sectional Area (mm²)	Weight per Meter (kg/m)	Yield Strength (MPa)	Tensile Strength (MPa)
6 mm	6	28.3	0.222	400 - 600	500 - 700
8 mm	8	50.3	0.395	400 - 600	500 - 700
10 mm	10	78.5	0.617	400 - 600	500 - 700
12 mm	12	113.1	0.888	400 - 600	500 - 700
16 mm	16	201.1	1.578	400 - 600	500 - 700
20 mm	20	314.2	2.466	400 - 600	500 - 700
25 mm	25	490.9	3.853	400 - 600	500 - 700
32 mm	32	804.2	6.313	400 - 600	500 - 700
