Beam wiper blades have no external frame to keep the rubber rigid. Instead, they have spring steel integrated into the rubber blade. Spring steel is a type of elastic steel that when used in a wiper blade, allows the blade to be flexible and contour to the curve of your windshield more. That’s why beam wiper blades have a cleaner wiping action than conventional ones.

Being a one-piece design, it also looks sleeker on your windshield. Beam wiper blades were initially used on luxury vehicles but are now commonly used on modern cars from almost all automakers.
