Spacing: The spacing between rebar bars also depends on the size of the bars. For example, for concrete with a strength of 3000 psi, 10# rebar typically requires a spacing of 10 inches (center-to-center) while 20# rebar typically requires a spacing of 20 inches (center-to-center). This spacing can also vary depending on the requirements of the specific project and local building codes.
Bendability: Because of its smaller diameter, 10# rebar is generally easier to bend than 20# rebar. This can be an advantage in projects that require complex shapes or curves.
Handling: The weight and size of 20# rebar can make it more difficult to handle and maneuver on a job site. This may require the use of specialized equipment, such as cranes or forklifts, to move and position the rebar.
Availability: The availability of 10# and 20# rebar can vary depending on the location and the specific supplier. In some areas, one size may be more readily available than the other.
It’s also worth noting that rebar is available in a range of sizes and shapes beyond just 10# and 20#. This includes sizes as small as #3 and as large as #18, as well as specialty shapes such as square and deformed rebar. The specific size and shape of the rebar used in a construction project will depend on the design requirements, load capacity, and other factors.
