Query: Rusty disaster

I wanted to replace the flame deflectors in my hybrid gas/charcoal grill to use lava rocks and this item was the closest in width and length. I had to cut the rack down to size for use. The item served its purpose, but after about a month, this product has proven to be quite an inferior product. The item is rusting badly sitting inside my grill. My grill is always covered when not in use with a multi-layered waterproof and weatherproof canvas cover. I'm surprised other buyers of this product in a different size didn't comment on this. I don't think it should be something that is acceptable because the grate will continue to deteriorate and require another replacement. I wish I had known about the inferiority of the product so I could avoid purchasing the item. Since I trimmed it already, I don't think I can return the product.
