Steel stirrups are used in construction as a reinforcing component in reinforced concrete structures. They are typically made of steel and are used to tie the reinforcing steel bars (rebar) together in a concrete structure. They help to distribute loads evenly throughout the structure and increase its overall strength and stability. Stirrups are typically bent into a specific shape or design in order to fit around the rebar and secure it in place. They are used in a variety of construction applications, such as buildings, bridges, and other structures.
