Surface Treatment Options for Torsion Springs | Electrophoresis, Galvanized & Oil Finish
At Bellair, we provide different surface treatment solutions for torsion springs to meet various application requirements and working environments.
🔹 Electrophoresis
Electrophoresis coating offers excellent corrosion resistance, uniform coating coverage, and strong adhesion. The coating can evenly cover the spring surface, providing better protection and helping extend the service life of springs, especially in humid or corrosive environments.
🔹 Galvanized
Galvanized coating applies a zinc protective layer on the spring surface, improving rust resistance and corrosion protection. It is a reliable choice for applications requiring better surface protection, especially for outdoor or moisture-prone environments.
🔹 Oil
Oil finish is a traditional and practical surface treatment for torsion springs. The protective oil film helps reduce oxidation, provides basic rust protection, and is a cost-effective solution widely used for general applications, storage, and transportation.
Bellair is committed to providing high-quality torsion springs with suitable surface treatment solutions according to different customer needs and application conditions.
Quality, reliability, and long-term cooperation are always our commitment.
