Talk to your supplier for ordering details. CAST IRON OXIDATION PROCESS Why are my grates turning orange? Raw cast iron starts out grey in color, but upon contact with water, a bright orange oxide develops. This loosely adhering layer (more commonly known as “rust”), easily washes or wears away, leaving behind a more tightly adhering oxide coating that actually protects the grate from further corrosion. What you end up with is a rich, chocolate brown patina, similar to any manhole cover in the street.

Depending on the environment the grates are placed in, the oxidation process generally lasts anywhere from a few months to a year. Just keep in mind that the more traffic and weather your grates receive, the faster their transformation. DURABILITY OF CAST IRON Will my grates rust away to nothing? Cast iron has been used for hundreds of years in the manufacture of items that need to be exceptionally durable and resistant to corrosion. For example, the Navy has traditionally made ship anchors out of cast iron. Our grates, just like those anchors, will last for decades in a raw state. PRE-AGING YOUR GRATES We generally recommend letting our grates age naturally, but for those who wish to bypass the bright orange oxidation phase of raw iron, we offer an eco-friendly “BAKED-ON-OIL FINISH” using recycled vegetable oil.
