Single Torsion Springs/Double Torsion Springs/White Zinc Plated

  A torsion spring is a type of spring that undergoes elastic deformation under the action of a twisting force. Unlike typical extension or compression springs, the load applied to a torsion spring is torsional; that is, when a torque is applied, the spring undergoes an angular displacement.

  The load on a torsion spring is an axial force, specifically a torque or twisting moment applied to the spring. The ends of the spring rotate through an angle as the load is applied.


  Torsion springs — Double torsion spring — White zinc plated are powerful and widely used spring products.Through appropriate material selection and structural adjustments, they can meet a variety of application requirements. If you need this type of spring, it is recommended to consult with a professional spring manufacturer to obtain the most suitable product.

White zinc plating is a common surface treatment method that coats the surface of the spring with a thin layer of zinc.

  • Rust prevention: Zinc is more reactive than iron and more readily reacts with oxygen to form a dense zinc oxide protective layer, which prevents the internal iron from oxidizing.

  • Improved wear resistance: The zinc coating increases the surface hardness of the spring, enhancing its wear resistance.

  • Enhanced appearance: After white zinc plating, the spring surface becomes bright and has a better decorative effect.
