what is a basketball rim made of

A basketball rim is typically made of steel, though the specific type of steel can vary. The rim is usually coated with a layer of galvanized or powder-coated finish to help prevent rust and corrosion, especially for outdoor courts. The rim is mounted on a backboard and is designed to withstand the force of the ball and players. The net that hangs from the rim is typically made of nylon or cotton, with nylon being more common due to its durability and weather resistance.
