　　Stainless steel signs are mainly produced by steel mills through various chemical reactions to produce steel. Stainless steel is very stable and not easily corroded by acids and alkalis. It is influenced by its chemical structure, and stainless steel is also less prone to rusting. Therefore, most signs that require long-term exposure to rainwater will be made of stainless steel. For example, there are signs and signs on the road. These adversarial and rust resistant requirements will be very high.

        

　　Another characteristic of stainless steel nameplates is that they are very sturdy and durable, and are not easily deformed. The advantages of stainless steel signage have basically been explained, let's briefly mention its disadvantages below. The density of stainless steel is 7.7-8.0, which is clearly worth it compared to the heavy iron 7.8. Stainless steel is very heavy, and due to its complex production, its price will also be relatively high.

　　The manufacturing process of aluminum signs is much more convenient, as they only need to be produced by electrolysis of aluminum and cryolite. Compared to stainless steel, aluminum plate has a much lower density, with a density of around 2.7. Therefore, aluminum is also relatively light, and aluminum plate prices are also relatively cheap. However, the corrosion resistance of aluminum plates is relatively weak and they are more prone to oxidation. Compared to stainless steel, aluminum is much softer, so there will be different deformations when exposed to a large amount.
