How to prevent stainless steel from rusting?

1. Protective coating

Steel corrodes through what is called "uniform corrosion." This means that corrosion occurs evenly across the entire surface of the exposed metal. Equipping steel with a protective coating is one of the most effective ways to prevent uniform corrosion from occurring. The coating acts as a barrier between the steel and corrosive agents such as rain, humidity and salt. Most preventive coatings are easy to apply, come in many forms, and can be oil or water-based.


2. Metallic paint

Painting metal surfaces is one of the easiest and most economical ways to prevent corrosion. A coat of metallic paint acts as a protective barrier against moisture and other corrosive agents. However, since paint itself is prone to chipping and deterioration, it is important to reapply when wear occurs.


3. Steel lubricant

Paint will not work on moving steel parts such as hinges, joints, and bearings. Often, painting over moving parts will cause the parts to stick and the paint to crack when the parts are forced. This is where water-based lubricant comes in handy. In addition to facilitating movement, lubricants also repel moisture that can cause corrosion.


4. Galvanized metal

Galvanizing is the process of applying a thin layer of zinc to protect steel from corrosion. Because zinc is more chemically active than steel, it oxidizes when exposed to air, acting as a protective coating. The galvanizing process requires industrial chemicals and extremely high temperatures. Therefore, galvanizing should only be carried out by trained professionals!
