Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Energy Storage & Torque Application: Designed to store and release rotational energy for applications requiring controlled force over small angles (e.g., garage door systems, automotive components).
  • High-Strength Material Construction: Made from cold-rolled steel with polished or galvanized finishes for enhanced durability and resistance to corrosion.

Key features

  • 1. Material Technology

    • With high-strength cold-rolled steel and corrosion-resistant surface treatments (bright finish, polished, or galvanized coating), you can ensure durability and longevity in harsh environments, outperforming standard steel springs prone to rust.

  • 2. Customization & Precision Design

    • With customizable dimensions (e.g., 243x2x30.5mm) and tight ±1% tolerance, you can achieve precise fitment and adapt to specific mechanical requirements, unlike non-customizable generic springs.

  • 3. Performance Parameters

    • With optimized torque capacity and cold-rolled steel construction, you can deliver consistent energy storage and release for heavy-duty applications, surpassing lower-grade materials in strength and reliability.

  • 4. Scenario Solutions

    • Designed for commercial and industrial use (e.g., garage door systems), these springs withstand repeated stress and environmental exposure, ensuring uninterrupted operation compared to consumer-grade alternatives.

  • 5. Certification Standards

    • With compliance to global standards (DIN, AISI, GB, JIS), you can guarantee safety and quality assurance for critical applications, meeting rigorous industry requirements.

Product details

Torsion Spring Torsion Spring Garage Door Accessory Torsion Spring

Our torsion springs are precision-engineered high-strength steel components designed for reliable energy storage and torque transmission in demanding applications. Crafted from cold-rolled steel with bright polished finishes and corrosion-resistant coatings, these springs feature customizable dimensions (e.g., 243x2x30.5mm) and green plastic end caps for secure, damage-free installation. Ideal for garage doors, automotive mechanisms, and industrial machinery, they combine durability with precise tolerances (±1%) to ensure consistent performance under repeated use.

Customization guide

Adjustable parameters include length, diameter, and thickness to meet specific torque requirements or spatial constraints. For example:

  • Length: Shorter springs for compact mechanisms, longer springs for greater energy storage.
  • Diameter/Thickness: Thicker coils for high-load applications (e.g., industrial doors) or thinner coils for lightweight systems.
