The upgrade that changes the marks more than the barbecue does · review
Two polished porcelain-coated grates at 6019 g (212.3 oz) — the most cast iron per square inch on this shelf.
What we would actually buy The densest cast iron on this shelf at eighteen grams per square inch — more metal per inch than the $140 Weber set. Two polished porcelain-coated grates for forty dollars, for Dyna-Glo and Blue Rhino.
The densest casting on this shelf — and the comparison with the most expensive grate here is the interesting part.
No listing on this shelf publishes a bar thickness, so weight over area has to stand in for it:
So a $39.99 two-pack carries more cast iron per inch than the $139.99 Weber set, and nearly twice the metal per inch of the $79.97 Aura grate.
Five grates on this shelf publish no weight at all and cannot be placed in that list.
A cast iron grate works by stored heat.
When six cold burgers land on a hot grate, the bars either hold their temperature or give it up. A light grate gives it up — the meat sits in its own juice and greys. A heavy grate keeps searing.
That is also why cast iron is slow to heat in the first place, and why preheating it properly is not optional.
Porcelain enamel is glass fused to the casting at high temperature. Its advantage over bare iron is simple: it does not rust. The two bare-iron listings on this shelf — COGRICHBF and QuliMetal — carry anti-rust routines, and this one does not need to.
Polishing smooths the faint orange-peel texture enamel comes out of the kiln with, so food releases more easily and a grill brush does not catch.
EasiBBQ states both: porcelain coated finish that prevents sticking, and durable polished porcelain coated cast Iron.
The trade, which QuliMetal argues on this shelf, is that a glass layer sears a little less hard than bare metal. And enamel can chip — at which point the chip rusts.
The smallest multi-grate set on this shelf, which is what the price per inch reflects:
Nearly double the Direct Store set per inch — and carrying noticeably more metal per inch in exchange.
Models: DGF350CSP, DGF350CSP-D, DGF350SNP, DGF350SNP-D, DG1-70-01-634-R, 101-03011. Dyna-Glo parts: 70-01-634, 101-03011, 70-01-635. Blue Rhino GBC1932L, Lowes 1139071.
Each grate is 15.8 × 10.5 inches — the figure to measure your old one against.
No incompatibilities published. Only QuliMetal names what it will not fit. Direct Store’s advice covers the gap and applies to every grate on this shelf: measure your original parts and compare before ordering.
No care instructions. No warranty.

On a grate, it is the single most useful number, and this is the heaviest casting per inch on this shelf. No listing here publishes a bar thickness, so the published weights and areas have to stand in: 6,019 g over about 332 square inches is 18.1 grams per square inch, against 16.8 for the Broil King, 15.6 for the $139.99 Weber Crafted set, and 10.0 for the $79.97 Aura grate — which carries barely more than half the metal per inch that this does. Mass is stored heat, and stored heat is what keeps a grate’s temperature up when cold food lands on it. That is the difference between a steak that sears and one that greys. Five grates on this shelf publish no weight at all, so they cannot be ranked.
Two, and they answer the two different objections to coated iron. Porcelain enamel is glass fused to the casting at high temperature, and its advantage over bare iron is that it does not rust — which is why the two bare-iron listings on this shelf carry anti-rust routines and this one does not need to. Polishing the enamel after firing smooths the faint orange-peel texture it comes out of the kiln with, so food releases more easily and a grill brush cleans it without catching. EasiBBQ states both halves: "porcelain coated finish that prevents sticking and allows for easy clean up" and "durable polished porcelain coated cast Iron". The trade, which QuliMetal argues on this shelf, is that a glass layer sears slightly less hard than bare metal — and that enamel can chip, where a chip then rusts.
Check the part number rather than the model name, because this listing publishes both. The models named are DGF350CSP, DGF350CSP-D, DGF350SNP, DGF350SNP-D, DG1-70-01-634-R and 101-03011, with Dyna-Glo original parts 70-01-634, 101-03011 and 70-01-635 — plus Blue Rhino GBC1932L and the Lowes 1139071 three-burner parts. Each grate measures 15.8 × 10.5 inches, which is the figure to measure your existing one against. What this listing does not publish is any incompatibility: only QuliMetal on this shelf names what it will not fit. And Direct Store gives the advice that covers the gap, which applies to every grate here — measure your original parts and compare before ordering.
