9 Inches Door Spring

Engineered for durability and consistent performance, our 9-inch industrial door spring provides reliable tension for commercial gates, overhead doors, and heavy-duty access points. Constructed from high-tensile spring steel, it is designed to withstand high-cycle use in demanding MRO and fabrication environments.

  • High-Tensile Spring Steel
  • 9-Inch Unloaded Length
  • High-Cycle Durability
  • Corrosion-Resistant Finish
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Our 9-inch door springs are manufactured from high-carbon spring steel wire, conforming to material standards like ASTM A228 for strength and elasticity. This material is selected for its superior fatigue resistance and ability to maintain tension over thousands of cycles. The spring is coiled to precise specifications to ensure uniform force distribution, providing smooth and controlled door operation. A protective finish, typically an oil coating or zinc plating, is applied to resist corrosion in various industrial settings, making it a reliable component for long-term use.

This industrial-grade door spring is essential for MRO (Maintenance, Repair, and Operations) and new construction projects involving commercial and industrial doors. It is commonly used in warehouses, manufacturing facilities, loading docks, and security gates where reliable self-closing or counter-balancing mechanisms are required. Fabricators and maintenance crews in the Los Angeles area rely on these springs for repairing overhead doors, heavy-duty screen doors, and custom gate applications, ensuring safety and operational efficiency.

Specifications

  • Material: High-Carbon Spring Steel (Meets standards similar to ASTM A228)
  • Standards: General Industrial Manufacturing Standards
  • Strength/Tensile: High Tensile Strength for Fatigue Resistance
  • Dimensions: 9 Inches (Unloaded Length); various wire diameters available
  • Finish: Oil Coated or Zinc Plated for corrosion resistance
  • Certifications: Certificate of Conformance available upon request

Applications

  • Industrial Maintenance: Repairing overhead garage doors, loading dock doors, and heavy-duty access panels.
  • Commercial Fabrication: Integrating into new security gates, industrial enclosures, and custom door systems.
  • Warehouse Operations: Ensuring self-closing functionality for fire doors and high-traffic personnel doors.
  • Agricultural: Used in heavy gates, machinery covers, and equipment hatches.

Target Users

This product is ideal for maintenance technicians, building managers, metal fabricators, and MRO professionals requiring durable hardware for commercial door and gate systems in the Los Angeles area.

Finish Options

Our 9-inch door springs typically come with a standard corrosion-resistant finish, such as a light oil coating or zinc plating. These finishes protect the spring steel from rust and environmental degradation, ensuring longevity in both interior and exterior applications.

How to Measure

To ensure you order the correct spring, measure the length of the existing spring from end to end when it is fully relaxed (unloaded). Also, measure the outside diameter of the coils and the wire diameter. Note the type of ends (e.g., looped, hooked) required for your specific application.

Example: '9-inch Door Spring, 1.5-inch outside diameter, 0.125-inch wire, looped ends'

Order Checklist

  • Product name and required dimensions (Length, Diameter, Wire Gauge)
  • Grade/material specification and quantity
  • End type requirements (e.g., hooks, loops)
  • Surface finish requirements
  • Certifications required (Certificate of Conformance)
  • Special handling or delivery requirements
