#6 (No. 6) Reinforcing Bar - ASTM (US)

#6 (No. 6) is a ASTM (US) reinforcing bar to ASTM A615 / A706 (Table 1). Its nominal diameter is 0.75 in (19.1 mm), giving a cross-section area As of 0.44 in² (284 mm²) and a mass of 1.502 lb/ft (2.235 kg/m). It is supplied in grade Gr.60 / Gr.75 / Gr.80 with characteristic yield f_yk = 420 MPa. The tables below give the total steel area for 1-10 bars and the area per foot of width at common bar spacings.
