Why is cast iron outdoor seating rarely anodized for color options?

Cast iron outdoor seating is seldom anodized for color options due to several practical reasons. First, cast iron is highly durable and resistant to wear, but its porous nature makes it prone to rust if not properly treated. Anodizing, a process more suited to aluminum, involves creating an oxide layer that doesn’t adhere as effectively to cast iron. Instead, cast iron furniture is typically powder-coated or painted, which provides better rust protection and longevity. Additionally, the traditional aesthetic of cast iron—often black or dark finishes—aligns with its classic, timeless appeal. While anodizing offers vibrant colors, the extra cost and limited durability on cast iron make it an impractical choice for outdoor use. Manufacturers prioritize functionality and weather resistance over colorful finishes, ensuring the furniture lasts for years in harsh conditions.
