How can I ensure my stainless steel mesh won't rust?

How to prevent stainless steel mesh from rusting?

Unfortunately, it's impossible to guarantee 100% that your stainless steel wire mesh won't rust. This is simply because you can't control your environment.

There are many factors that cause stainless steel wire mesh to rust. 

Firstly, when different metals come into contact with the surface of the wire mesh, the protective layer on the surface may be damaged, subsequently leading to corrosion/rust.

For example, if stainless steel wire mesh is used outdoors, iron dust containing various alloy particles from the external environment will inevitably adhere to the wire mesh surface. This, in turn, will lead to corrosion over time, eventually forming a rusted mesh surface.

Of course, can rust be avoided when used indoors? However, even indoor use may involve exposure to corrosive chemicals, such as chlorine in indoor swimming pools, or particulate matter from filtration and screening processes.

Therefore, you should avoid using any cleaning products that are not suitable for stainless steel. Otherwise, it may cause the building mesh to rust more quickly.

So, regarding how to prevent stainless steel mesh from rusting, Dashang offers the following points.

1. Correct material selection: Choose the appropriate stainless steel grade based on the intended use environment. 304 is generally sufficient for kitchens, while 316 is recommended for coastal or industrial areas.

2. Keep it clean: Clean the stainless steel mesh regularly to remove salt, sweat, oil, dust, and any possible iron filings.

3. Avoid scratches: During installation and use, minimize mechanical damage to the surface.

4. Prevent contact: Avoid prolonged direct contact with dissimilar metals (especially carbon steel), or use insulating spacers at contact points.

5. Prompt treatment: If even minor rust is detected, clean it immediately with a stainless steel cleaner, a scouring pad, or a soft-bristled brush. Rinse thoroughly with water and allow the passive film to naturally reform in the air.

Rust on stainless steel mesh isn't caused by "fake" conditions, but rather by the destruction of the protective passive film on its surface and the excessive presence of corrosive agents (especially chloride ions) in the environment. Understanding this will help you better select and use stainless steel products, maximizing their corrosion resistance.

In woven mesh products, embossed weaves may develop rust. This is because the stainless steel wire undergoes a cold-working process, which easily damages the surface oxide film. To avoid this, use high-quality stainless steel raw materials and take protective measures during transportation and storage, maintaining a dry and clean storage environment. Dashang Wire Mesh strictly selects austenitic stainless steel raw materials from renowned steel mills such as Qingshan Taiyuan Iron and Steel Co., Ltd. We perform spectral analysis on each batch of raw materials to ensure that the content of core elements such as chromium, nickel, and molybdenum meets national standards. Each batch of raw materials is controllable and traceable.

Regarding Dashang's stainless steel mesh products, in addition to ensuring that the raw materials meet customer requirements, to prevent the stainless steel mesh products from rusting, we also consider three aspects: keeping them clean, avoiding scratches, and preventing contact. Dashang's packaging for stainless steel mesh is as follows:
