Charbrofire cast-iron replacement grill grates for Char-Broil G460 G421 3-4 Burner Matte Enamel, Heavy-Duty Searing

These Charbrofire replacement grill grates are heavy-duty matte enamel cast-iron cooking grates engineered to restore even heat, superior searing, and long-lasting performance to compatible Char-Broil and related grills.

If your Char-Broil or compatible gas or coal grill has worn, cracked, or flaking grates, this set offers a durable cast-iron alternative sized to fit many Char-Broil Performance, Advantage, Classic, Thermos and Gourmet series models (examples: G460-0500-W1, G421-0008-W1, 463344116, 463370719 and others). Unlike thin porcelain-coated pieces that chip over time, these matte enamel cast-iron bars are thicker, keep heat longer and deliver solid sear marks while standing up better to regular use when seasoned and cared for properly.

Which Char-Broil and related models will these grates replace?

These grates are designed to be compatible with a broad set of Char-Broil model numbers across 3- and 4-burner lines as well as several specialty and older models. Check your grill’s part number against the provided compatibility list before ordering.

• Fits Char-Broil models like G460-0500-W1, G421-0008-W1 and multiple 4633xx/4634xx series.
• Listed compatibility covers Performance, Advantage, Classic, Thermos and Gourmet grills.
• Also cross-referenced to some Kenmore and Broil King part numbers for broader fitment.

How do these cast-iron grates improve cooking performance?

Cast iron transfers and retains heat much better than thin steel or flaked porcelain. That means faster, more consistent searing, improved temperature stability across the cooking surface, and deeper grill marks on steaks, chops and vegetables.

• Matte enamel finish prevents bare-metal rust while preserving heat transfer.
• Thicker solid rods hold higher temperatures for longer searing windows.
• Even heat distribution reduces hot-and-cold spots across the grate.

What are the construction and care details I should know?

The grates are made from heavy-duty cast iron with a matte enamel coating to resist rusting and reduce sticking when properly seasoned. They require a little routine maintenance—seasoning with oil and avoiding harsh detergents—to maximize lifespan.

• Material: matte enamel cast-iron for high heat retention and durability.
• Care: pre-season with cooking oil, clean with a brush, and dry to avoid rust.
• Not a porcelain-coated replacement—enamel finish is more resistant to chipping.

What should I check before buying to ensure proper fit?

Confirm your grill’s existing grate part number or measure the cooking area to match the replacement dimensions. Cross-reference the model numbers listed with your grill’s manual or current grate stamping to avoid returns.

• Compare your existing part number (e.g., 463344116, 463370719) with the compatibility list.
• Measure length and width of the cooking surface if part number is unavailable.
• Consider burner count (3 vs 4 burners) and grate shape when matching fitment.

Who is this for: These Charbrofire cast-iron replacement grates are intended for grill owners who need a robust, long-lasting grate solution for Char-Broil and compatible grills, including older or discontinued models. Choose these grates if you want better heat retention and searing capacity than thin porcelain-coated grates, are comfortable with basic cast-iron care (seasoning and brush-cleaning), and need a direct fit for the model numbers listed.
