Abstract
A screed bar for a vibratory concrete screed is formed from a long hollow extrusion having generally flat enclosing walls and defining in cross section two triangular sections that share a common interior wall. This construction has been found to provide more uniform distribution of vibrations along the entire length of the screed bar as compared to prior screed bar constructions.
