What are the effects of acid rain on stainless steel outdoor bench surfaces?
Acid rain can significantly affect stainless steel outdoor bench surfaces, leading to corrosion and aesthetic damage. When acidic pollutants in rainwater react with the metal, they weaken the protective chromium oxide layer on stainless steel, making it prone to rust and pitting. Over time, this can compromise the bench's structural integrity and appearance. Regular cleaning and applying protective coatings can help mitigate these effects. Choosing high-grade stainless steel (e.g., 316 grade) with better corrosion resistance is also advisable for outdoor use in areas prone to acid rain.
