Coatings for Your Springs

One thing that many industrial springs have in common is the coating on the surface of the springs. Most springs are made from inexpensive metals, such as steel, which will eventually corrode andfavicon rust if it does not receive an external coating. Many spring manufacturing companies create various coatings for springs depending on the final use of the spring. You can choose the coating that you want for your springs, depending on what the company offers and what you need your springs to do. Each coating has their own benefits and drawbacks that make them ideal for different situations and uses.

Galvanized: A galvanized coating is a series of chemical baths that coat the metal in a protective film that prevents the metal from rusting. This is essential for springs that will be used in moist climates, such as outdoors, or near other sources of moisture that can damage the springs and cause rust to form.

Metal plate: A metal plate coating is a thin coating of a stainless metal applied over another kind of metal. Metal plate coatings not only protect the springs from corrosion and rust, but they also can make the spring look more attractive, such as with a gold coating for indoor use, such as with doorstop springs.

Plastic: Other springs can be coated with plastic to protect them from weathering and to make them safe to the touch. A plastic-coated spring may be used in children’s playthings, such as outdoor playground equipment to prevent the springs from overheating and causing physical burns.

Rubber: A rubber coating has similar uses to a plastic coating over springs. One advantage of rubber over plastic is that the coating is more durable and can resist cracking and breaking. However, rubber can break down and crack with prolonged sun exposure, which makes them less suited to outdoor use.
