Windshield Wiper

Windshield wipers need to have the right balance of elasticity and pressure to ensure that the wiper blades adhere tightly to the windshield surface and apply pressure evenly. Carbon steel, with its excellent strength and hardness, can withstand high levels of stress and loads while meeting processing conditions. It is the optimal choice for both carbon steel suppliers and cold-rolled steel suppliers.
