Galvanized Wiper Spring
A Galvanized Wiper Spring is an essential component in automotive windshield wiper systems, designed to maintain consistent pressure between the wiper blade and the windshield surface. By ensuring stable tension, the wiper spring allows the wiper blade to achieve smooth, streak-free wiping performance under various weather conditions. Featuring galvanized protection, it offers excellent corrosion resistance and long-term durability, even in humid, rainy, or snowy environments.
What Is a Galvanized Wiper Spring?
A Galvanized Wiper Spring is usually made from high-strength spring steel that undergoes a zinc coating (galvanization) process to prevent rust. The zinc layer protects the spring from oxidation, extending its service life and improving overall performance in harsh outdoor conditions.
This spring plays a crucial role in the wiper arm mechanism by:
Providing tension to press the blade onto the glass
Maintaining uniform contact across the windshield
Keeping the wiper stable during high-speed driving or strong wind
Enhancing cleaning performance and driver visibility
Galvanized wiper springs are widely used in cars, trucks, buses, agricultural vehicles, construction equipment, and specialty vehicles.
Key Features of Galvanized Wiper Spring
1. Superior Corrosion Resistance
Galvanization forms a durable zinc coating that prevents rust and oxidation. This ensures stable performance even in rain, snow, and long-term outdoor exposure.
2. High Elasticity & Stable Tension
Made from premium spring steel, the wiper spring maintains strong tensile force, ensuring the wiper blade fits tightly on the windshield for maximum cleaning efficiency.
3. Long Service Life
The combination of high-quality steel and protective galvanization provides excellent fatigue resistance, reducing wear and extending the lifespan of the wiper system.
4. Weatherproof & Anti-Aging
The spring withstands UV exposure, humidity, road salt, and temperature fluctuations, making it ideal for all-season driving.
5. Lightweight, Compact Design
Engineered for easy installation and compatibility with most automotive wiper arms.
Typical Applications
Galvanized Wiper Springs are widely used in:
Passenger car windshield wipers
Truck and bus wiper systems
Heavy-duty construction machinery
Agricultural vehicle wipers (tractors, harvesters)
Marine and industrial wiper systems
Customized wiper assemblies for specialty vehicles
In each application, the wiper arm tension spring ensures smooth, stable wiping performance.
Material Options
Most Galvanized Wiper Springs are manufactured using:
High-Carbon Spring Steel (e.g., 65Mn, SAE 1074/1075)
Stainless Steel (optional upon request)
Galvanized Spring Steel Wire with protective zinc coating
The galvanization methods include:
Electro-galvanized
Hot-dip galvanized
Zinc-nickel coating (optional for premium corrosion resistance)
Benefits of Using a Galvanized Wiper Spring
Improved wiping performance
Consistent pressure ensures the blade removes water, dust, and debris efficiently.
Longer-lasting than non-coated springs
Zinc coating protects against rust, preventing tension loss or breakage.
Cost-effective durability
Offers excellent performance-to-cost ratio for automotive manufacturers and replacement markets.
Supports OEM & aftermarket needs
Custom shapes, lengths, and tension levels can be manufactured to meet specific vehicle models.
