4. Terrain and Preparation The condition of the land where the fence will be installed plays a significant role in cost. Uneven or rocky terrain may require additional preparation, such as grading or concrete footings, which can increase labor and material costs.

Next, the load capacity is critical. The maximum load, or the force that the spring must withstand, will dictate the material choice. Common materials for compression springs include music wire, stainless steel, and oil-tempered carbon steel, each chosen for their unique properties such as tensile strength and fatigue resistance.
The surface finish of a spring can impact its fatigue life, corrosion resistance, and interaction with other components. Specifications for surface finish ensure that springs meet the desired level of performance and appearance.
