100% Original Factory Trailer Roll Up Door - Roll Up Garage Door Springs – Bestar Detail:

We specialize in manufacturing high quality Roll Up Garage Door Springs, which meet ASTM A229 standard. All our Roll Up Garage Door Springs are made from high-tensile, oil-tempered spring wire and come in a range of sizes to suit different door weights.

Each month we make delivery almost 5800 pairs Roll Up Garage Door Springs to USA, Canada, Australia and Saudi Arabia.

Some smaller Roll Up Garage Doors use only one torsion spring, while most larger Roll Up Garage Doors use two torsion springs. Each torsion spring on the door typically has at least one turn when the door is fully open. This extra tension keeps the door open by restricting the curtain from unrolling off the drums. As you close the door, each torsion spring winds up even more. This extra tension allows the springs to lift extra weight. The extra weight comes from a greater portion of the curtain hanging off of the drums.

 

Standard Features:

(1) High tensile

(2) Oil tempered

(3) Factory lubricated 

(4) Corrosion resistant

(5) Long cycle life

(6) Custom size available

(7) Meet ASTM A229 standard
