Consistent Counterbalance & Safety
Our garage door torsion springs provide stable lifting force throughout the door’s travel, reducing workload on operators, cables, and hardware. Accurate matching of spring torque to door weight ，this helps ensure smooth, controlled operation and ensures safer daily operation for users.
Durable Materials & Long Cycle Life
Our garage door springs are manufactured from high-tensile oil-tempered steel with controlled heat treatment and precise coiling. This construction provides reliable fatigue resistance under repeated opening and closing cycles, supporting both residential and high frequency use commercial environments when correctly selected and installed.
Flexible B2B Customization & Supply
KOP DOOR supports garage door torsion springs with custom wire sizes, inner diameter, free lengths, left & right directions, surface treatments, private labeling, and bulk packaging (Wooden case &Nude packing for container loading).
This means two winding directions of garage door torsion springs. Left-hand wound springs are counter‑clockwise coiled, while right-hand wound springs are clockwise coiled. One left-hand and one right-hand spring are normally used as a matched pair for standard double spring garage doors.
Our torsion springs are manufactured with high-tensile oil-tempered steel wire ,72B,82B(domestic standard). Surface treatment is applied for anti-rust and anti-corrosion performance for long-term outdoor use.
Cycle life depends on frequency of use. Our standard torsion springs offer 10,000-50,000 cycles under normal operating conditions. Heavy-duty options for high-frequency use are also available.
Torsion springs are mounted on a torsion shaft above the door and save energy by torsion to provide balancing force; they are the mainstream solution in the North American and European markets at present. Extension springs are mounted on the tracks on either side of the door and save energy by tension.
We maintain a range of standard sizes for fast delivery and also accept custom dimensions, wire gauges, free lengths, and packaging for bulk or OEM orders. Share your technical requirements and volume expectations for a quotation tailored to B2B supply.
