Why are stainless steel outdoor chairs less prone to staining than other metals?

Stainless steel outdoor chairs are less prone to staining compared to other metals due to their unique composition. The key factor is chromium, which forms a passive oxide layer on the surface when exposed to oxygen. This layer acts as a protective barrier, preventing rust and corrosion. Unlike iron or regular steel, stainless steel resists moisture, UV rays, and harsh weather conditions, making it ideal for outdoor use. Additionally, its non-porous surface repels dirt and stains, ensuring easy maintenance and long-lasting aesthetics. For durability and low upkeep, stainless steel stands out as the top choice for outdoor furniture.
