Product Description
In addition to stainless steel springs, many customers prefer to choose zinc-plated steel compression springs. Because the materials are cheaper than stainless steel, the zinc-plated compression steel spring is not only more competitive in price but also has excellent anti-corrosion and anti-rust properties.
Therefore, zinc-plated steel compression springs can replace stainless steel springs in many applications.

Measurement Method of Compression Springs
When you want to purchase the compression spring, you should measure the sizes below:
1. Outer Diameter of Compression Springs
2. Free Height of the Compression Springs
3. The Wire Diameter of the Wire Used for the Compression Springs.
Please use a vernier caliper instead of a tape measure when measuring the compression spring size.
Because the vernier caliper can be accurate to 0.01mm, which is more accurate, while the tape measure can only be accurate to 1mm, which is very error-prone, resulting in a large difference between the measurement result and the actual one.
Usage:
A compression spring also called a tension spring, is a helical spring that bears axial tension. When not under load, the coils of the compression springs are generally tight and there is no gap between the coils.
Compression springs are widely used in medical respiratory equipment, sports equipment, medical equipment, hand tools, furniture, doors and windows, shock absorbers, pump springs, mechanical and electronic protective hardware, fluid control valves, mechanical aerospace components, actuators, switchgear machines, instruments, and other fields.
