Thank you for your inquiry. This fire pit ring is made of heavy-duty steel with a high-temperature paint finish. While it is designed for outdoor durability, it is not rust-proof. If left in a low-lying area with standing water for extended periods, the steel will eventually develop rust. To maximize its lifespan in such conditions, we recommend placing it on a raised, well-draining stone or gravel base to prevent direct contact with water.
