Material choices
Wire wound springs are typically made from medium and high strength steels, nickel alloys, titanium and stainless steels that have undergone heat-treating and cold reduction. Machined springs use somewhat similar materials. Spring wire and malleable bar are common to wound springs, but cannot be used for machined springs. A completed wound spring will retain various amounts of residual stress. While stress relieving processes can reduce residuals in wound product, the sum is not zero.
Because extension springs are designed to attach components to each other, a hook or eyehook is affixed to each end of the coil. Once the spring is attached to either component, the tension and resistance controls constant energy. The further the spring is extended, the greater the resistance and energy are released. Any visible signs of pitch between the coils indicate that the spring’s service life has ended. Extension springs are used in farm equipment from tractors to combine harvesters, in washing machines to stabilize the drum, in most baby carriages, and they provide the bounce for trampolines.
Spiral coil springs have many applications, notable ones include:
Thời điểm mua cũng là một yếu tố cần lưu ý. Ngành nông nghiệp thường có những mùa vụ cụ thể, và giá dây rào có thể biến động tùy thuộc vào thời điểm trong năm. Thông thường, vào mùa thu hoạch, nhu cầu về dây rào sẽ tăng lên, dẫn đến giá cả có thể cao hơn. Ngược lại, vào mùa thấp điểm, người nông dân có thể tìm được giá tốt hơn.

Moreover, wire supports are relatively easy to install and adjust, making them a popular choice among novice and experienced gardeners alike. They can be driven into the ground at any angle and removed or relocated as needed, allowing for a dynamic gardening experience. This flexibility is vital when dealing with perennials or plants that may need repositioning as they grow.
