Detailed Description of Extension Spring
Extension springs are coiled elastic components with double-end hooks, made from high-carbon spring steel or 304 stainless steel wire. After heat tempering treatment, these springs possess stable elasticity and anti-fatigue properties, and are not easily deformed or broken after repeated stretching.
The surface galvanized finish offers reliable rust resistance for outdoor farming applications; the stainless steel type is suitable for humid, coastal, and corrosive orchard environments.
Multiple sizes are available: wire diameter ranges from 1.2mm to 2.0mm, free length between 50mm and 150mm, with standard round hooks for easy installation.
Main function: maintaining tension on 1.6mm and 2.0mm aluminum solid wires used in agricultural electric fencing, keeping the wires tight throughout the year, absorbing impacts when livestock hit the fence, effectively preventing wire sagging
