The designation 20mm typically refers to the wire diameter or the outer diameter of the spring in millimeters, although it can also denote different dimensions depending on context. Depending on the specific requirements, the 20mm compression spring can be manufactured using various materials—most commonly stainless steel, carbon steel, or alloy steel. These materials are chosen for their strength, durability, and resistance to fatigue, which are critical in ensuring the longevity of the spring.

In this article, we’ll cover various aspects of compression coil springs, including their construction, materials, load capacity, and the different types of ends they can have. We’ll also discuss the key factors to consider when selecting a coil spring, such as required spring force, continuous loading, and the environment in which it will be used.

4. Durability Structures reinforced with wire mesh tend to have improved durability against environmental factors. The mesh helps prevent cracking and spalling, which can lead to water infiltration and corrosion of embedded steel. This characteristic extends the lifespan of concrete structures, making them more resilient over time.

1. What is a spiral coil spring?

When selecting compression coil springs, there are several important factors to consider to ensure the spring meets the application’s requirements. Here are some of the key factors:
