🚪 Choosing the Right Garage Door Spring for Your Business

When it comes to garage doors, the spring may look like a small part, but it’s the key to making the whole system work safely and smoothly. Many buyers often ask us: “What kind of spring should I choose?” Let’s break it down in a simple way.

🔧 Types of Garage Door Springs

1. Torsion Springs

   • Mounted above the door

   • More durable and safer for most residential and commercial doors

   • Common sizes: 2”, 2 5/8”, 3 3/4” ID

2. Extension Springs

   • Installed on the sides of the door

   • Cost-effective and easy to replace

   • Suitable for lighter doors

3. Industrial Heavy-Duty Springs

   • Designed for large warehouse and factory doors

   • Made with thicker wire and larger inner diameters

   • Can handle heavy weight and high daily usage

📐 What to Look for in a Spring

• Material Quality: Springs made from ASTM A229 82B high-carbon steel can last up to 70,000–80,000 cycles.

• Surface Finish: Electrophoretic coating or galvanizing helps prevent rust and extends lifespan.

• Correct Size: Inner diameter (ID), wire diameter, and length must match your door for safe operation.

• Supplier Reliability: A good supplier doesn’t just sell springs; they provide technical support, on-time delivery, and after-sales service.
