Steel rebar sizes chart
U.S. rebar sizes:Imperial bar designations represent the bar diameter in fractions of 1/8 inch, such that #8 = 8/8 inch = 1 inch diameter. Area = (bar size/9) 2 such that area of #8 = (8/9)2 = 0.79 inch. This applies to #8 bars and smaller. Larger bars have a slightly larger diameter than the one computed using the 1/8 inch convention. 



European steel rebar sizes: Metric bar designations represent the nominal rebar diameter in millimetres. Bars in Europe will be specified to comply with the standard EN 10080. Unit weights for rebar or reinforcing bar length 11,75 meters. Rebar weight table for reinforcing bars from 5, 5 mm to 32 mm.  


Steel reinforced bar concrete beam formulaThere are four main rules for steel reinforced concrete beams: 2. To count the width of the concrete beam: Multiply the height by 5 and devide by 7. For example: the beam height is 0,2 meter. 0,2 x 5 / 7 = 0,14 m. 3. The beam should be enforsed with at least 4 steel re bars d1214 in two levels. 4. The concrete should be applied all volume at once without big waiting gaps.
