Hongso Porcelain-Enameled Cast Iron Grill Grates — 3-Piece Replacement for CharBroil 4/5-Burner, Heavy-Duty Heat Retention

These Hongso porcelain-enameled cast iron replacement grill grates are designed to fit select CharBroil 4- and 5-burner Performance grills, restoring even heat, clear sear marks, and long-lasting durability.

If your CharBroil Performance 4- or 5-burner grill needs new cooking grates, this three-piece Hongso set offers two larger grates and one narrow center grate engineered to match the original fit and cooking performance. Manufactured from heavy-duty porcelain-enameled cast iron, the rods are thick enough to retain and distribute heat evenly while producing attractive sear lines. The set replaces several CharBroil part numbers across different model years — but always measure your existing grates to confirm fit before ordering.

Will these grates fit my CharBroil Performance 5-burner grill?

Yes — the set is created to replace multiple CharBroil 5-burner grate part numbers commonly used across Performance series models, but fit depends on your grill's specific measurements and original parts. Check the listed compatible part numbers and compare sizes to your current grates.

• Compatible with CharBroil part numbers including 463347519, 463347518, 463373019, and related variants.
• Includes two larger grates sized 18 3/16" x 9 1/4" and one narrow grate 18 3/16" x 6 1/2".
• Total combined length for the three-piece set equals 18 3/16" x 25" — verify against your grill's cooking surface.

How do these cast iron grates affect heat and searing?

The grates are made from heavy-duty cast iron with porcelain enamel, giving them strong heat retention and the ability to produce consistent sear marks. Thicker rods (approximately 10.25 mm diameter) hold more thermal mass than thin steel grates, helping to stabilize temperature when you add food to the surface.

• Porcelain enamel creates a semi-nonstick surface that helps prevent food from sticking and simplifies cleanup.
• Thick cast-iron rods retain and spread heat for even cooking across the grate.
• Leaves attractive grill marks while keeping food flavor intact by limiting flare-ups when used properly.

What materials and build quality can I expect?

These replacement grates are cast from heavy-duty iron and finished with a porcelain enamel coating. That combination offers the durability and thermal properties of cast iron combined with a protective finish that resists rusting and simplifies maintenance compared with bare cast-iron surfaces.

• Porcelain-enameled cast iron for durability and improved corrosion resistance.
• Rod diameter ~10.25 mm for solid heat retention and longevity.
• Manufactured to match original model codes like G470-0003-W1 and similar OEM references.

How should I maintain and install the replacement grates?

Installation is typically straightforward: remove the old grates and set the new pieces into the grate supports, ensuring the narrow center section aligns with the burner layout. Maintenance is routine but important — keep grates clean to extend life and preserve the enamel finish.

• Before ordering, measure your existing grates and confirm model compatibility.
• Hand-wash with warm water and a soft brush; avoid metal scouring pads that can damage enamel.
• Season lightly with cooking oil after cleaning to reduce sticking and protect the surface.

Who is this for? Grill owners with CharBroil Performance 4- or 5-burner models who want a durable, heat-retaining replacement that restores searing performance and looks. This set is aimed at people replacing worn, rusty, or warped grates who prefer the feel and cooking results of cast-iron surfaces finished with a porcelain coating. Measure your current grates and confirm part compatibility before purchasing to ensure a proper fit.
