Specification
Steel rebar is metal bars often used in construction for pouring concrete or supporting walls and columns. The rebar can
be smooth, though they are frequently manufactured with deformations that create greater texture to which concrete can
adhere, creating a stronger bond that helps prevent cracking of concrete. These deformations do not create weaknesses in
the rebar, and when rebar is measured to determine its diameter, it is typically measured at the narrowest point. Strength
grades indicate the amount of pressure the steel rebar can withstand, and grade and diameter are typically presented in both
imperial and metric units.
Most grades of steel used in rebar cannot accept welding; such as, to adjacent steel plates or as means to bind single
pieces of rebar together. However, special grades of rebar steel and welding rods make welding by expert welders possible.
