#10 rebar, or reinforcing bar, represents one of the larger standard sizes of steel reinforcement used in concrete construction. With a nominal diameter of 1.27 inches (32.3 mm) and a cross-sectional area of 1.27 square inches, this hefty reinforcement plays a crucial role in major construction projects.
Commonly used in foundations, columns, and heavy civil engineering structures, #10 rebar provides exceptional tensile strength to concrete elements that must withstand significant loads. Its primary applications include:
The "10" in #10 rebar historically referred to the number of eighths of an inch in the bar's diameter, though modern specifications now use precise measurements. This size of rebar is particularly valued in seismic zones, where structures must resist substantial lateral forces.
While smaller rebar sizes are handled manually, #10 rebar typically requires mechanical assistance for placement due to its weight - approximately 4.303 pounds per linear foot. This considerable mass makes it ideal for projects requiring robust structural integrity but also demands careful planning for transportation and installation.
