Note: Metric bar designations represent the USA Rebar Sizes. 5) 24 (610) 26 (661) 240000 (1067. For walls and columns, # 4 rebar is better, as these structures require more strength. This corresponds to 0. Importance of Measuring Rebar Diameter Correctly. 128 inches (28. It is often trusted as a strengthening material in slabs, piers, columns and walls. 5. Physical characteristics of #4 Rebar: Imperial Bar Size: #4 "Soft" Metric Size: #13; Weight per unit length: 0. 561 kg/m. Current A615 specification covers bar sizes #14 and #18 in Grade 60, and bar sizes #11, #14 and #18 in Grade 75. Because #9 rebar and concrete have comparable heat expansion coefficients, rebar offers an ideal solution to the construction challenges posed by concrete’s inherent shortcomings in tensile strength. This applies to #8 bars and smaller. an rx qo vi hm ww zh lx lt ru
