The Goldstream sump tray is made of Corten steel, it comes unrusted. When you place the Goldstream sump outside a rust layer will form fairly quickly. Depending on the weather and environment, each steel fire bowl will take on a beautiful rust brown-orange color in its own way. Corten steel is durable and has a unique metal alloy. The combination of these metals creates a dense layer of oxidation. The strength of the steel is similar to that of stainless steel. So you will have endless enjoyment from this durable fire bowl.

• Basically, the Goldstream sump requires no maintenance. The rusting process causes a protective layer to form on the steel.
• Place the steel catch basin in a place where it can always dry quickly after a rain.
• Remove wet leaves from the catch basin to prevent accelerated corrosion.
• Please note: Corten steel can deposit rust on the surface.
