Quick answer
The Onlyfire Cast Iron Sear Grate for Weber Kettle 22.5" is the honest alternative to Weber's official sear grate, provided you own that exact model. It's a porcelain-enamelled cast iron insert —not stainless steel— at 11.8", cut to fit the central GBS slot of the 22.5" Kettle, so it delivers focused sear marks without paying for the official part. It's for Weber Kettle 22.5" owners (Original Premium, Master-Touch, Performer). It isn't universal: if your grill isn't that Kettle with a GBS grate, the part won't fit.
Porcelain-enameled cast iron insert — NOT stainless. 11.8" diameter sized to drop into the central GBS hole of the Weber Kettle 22.5". Not universal: it's cut for that exact geometry.

FAQ
Which grills does this sear grate fit?
It isn't universal: the cast iron insert is cut to 11.8" diameter to seat in the central Gourmet BBQ System (GBS) opening of the 22.5" Weber Kettle. If your kettle has the removable-center GBS grate, it drops straight in. Without that central system, this piece won't seat properly.
Is it stainless steel or cast iron?
It's porcelain-enameled cast iron, not stainless steel. That difference is deliberate: cast iron stores and holds far more heat, which is exactly what you want to lay down deep sear bars on a steak. The porcelain enamel makes cleaning easier and protects the metal against rust.
What exactly is a sear grate for?
It concentrates heat in thick cast iron bars to create the deep grill marks and Maillard crust that define a good sear. Swap it into your GBS grate's central disc just before the meat goes on: you sear over the searing-hot iron, then move to indirect heat to finish cooking.
