| especially steel rebars have found extensive | | | | industry for rebar sizes – Imperial sizes and |
| usage to provide strength to the building | | | | Metric sizes. Imperial bar method (USA |
| structure. Concrete is basically high density | | | | convention) represents rebar diameters in |
| material and has less strength when applied | | | | fractions of 1/8 inch, such that #8 = 8/8 inch = 1 |
| tension. To counter this problem, steel rebar | | | | inch diameter. Metric bar method (Canadian |
