Note: Our Polylok ductile iron grates are designed to provide durable and long-lasting performance. However, please note that we do not provide a warranty against rust formation. To help prevent rust and extend the life of your grates, we recommend regularly wiping them with a thin layer of oil. This simple maintenance step will help protect your grates and minimize the risk of further rusting.
