Steel Rebar are also known as Reinforcing Steel Bar in UK. There are 2 major types of Rebar which are Composite and Steel. Rebars are produced from Mild Steel Rods and Mesh which strengthen the concrete structures and foundation. Mild Steel Rebar are manufactured in various grades including 40, 60, 75, 80, 100 as per ASTM A706. These low-alloy steel A706 Reinforcing Bar are weldable. Here you can find Rebar Weight Calculator to estimate the weight in Kg and Square Foot. This Calculator help the engineers to calculate exact Rebar Weight Per Linear Foot. Also find an accurate Rebar Weight Chart to estimate for small or large construction projects.
The value of the given Rebar Weight Table is according to BS8666, CSA A23.3 and ACI 318. Black and Epoxy Coated Rebar may impact the weight which depends upon the thickness of coating. Also refer reinforcement weight of different countries such as USA, Europe and Canada.
