What is rebar/ reinforcing bar?, Rebar is short form of reinforcing bar, it is steel bar or Steel wire provided as tension bar, used in reinforced concrete structure like column, beam and slab of house construction and it also used in reinforced masonry structure. It is used to increase the tensile strength of concrete structure.

Reinforcing bar/rebar surface is often deformed with ribs to promote a better bonding with concrete material and reduce the risk of slippage. The most common Reinforcing bar/rebar is carbon steel of hot rolled round bar with the deformation patterns, the Steel rebar may be also coated with epoxy resin material, design to resist effect of corrosion mostly in saltwater environment.

US based steel/ reinforcing bar sizes and their diameter, as we know that different countries in the world have their own gradation, specification of Steel and record of measurement for reinforcing bar. First remember that rebar is measured differentially in United States and Europe. while the United states, it uses the Imperial measurement system. Europe and most of rest of world uses the metric system.

In this article we briefly explain “Rebar weight per foot: (#3, #4, #5, #6, #7, #8, #9 & #10)”, based on Imperial measurement system. This will help to viewers in better understanding and it is easy to choose the most suitable rebar you wanted according to requirement.

Imperial rebar size/ Reinforcing bar size

US/ imperial rebar sizes gives the diameter in units of 1/8 inch (3.2mm), for bar sizes #2 to #10 we use this formula, for example size of number 2 (#2) rebar is of 1/8 inch in metric system measurement, such that 2×1/8 inch = 0.25 inch or 6mm.
