Hongso Porcelain-Enameled Cast-Iron Grill Grates for Char-Broil Thermos/Classic — 3-Piece Set, Improved Searing & Easy Cleanup

If your Char-Broil grill has uneven heating, faded sear marks, or broken grate bars, these Hongso replacements bring back the cooking surface you expect. Each grate measures 16 13/16" x 9 7/16" (three together equal 16 13/16" x 28 5/16"), made from cast iron with a porcelain enamel finish to combine heat retention with easier cleanup. They match numerous Char-Broil and compatible model numbers so you can fit them in the grill you already own without custom modification.

How do porcelain-enameled cast-iron grates change cooking results?

Porcelain-enamel over cast iron combines the heat-holding and searing strength of cast iron with a protective porcelain surface. That pairing helps create clearer grill marks, more consistent crust formation, and improved temperature stability across the cooking surface.

• Porcelain finish reduces sticking and simplifies scrubbing
• Cast iron core retains and distributes heat for better searing
• Durability resists chipping and corrosion when maintained correctly
• Sizable grate bars concentrate heat for distinct grill marks

What installation and maintenance should I expect?

Installation is straightforward: remove the old grates, confirm measurements, and drop the Hongso pieces into place. Routine care preserves the porcelain and cast iron — clean with a grill brush after use, avoid harsh abrasives, and dry thoroughly to prevent rust at exposed cast-iron spots.

• Simple swap: no tools for most model installs
• Clean warm with a medium brush; avoid metal scouring pads on enamel
• Season lightly if porcelain chips expose raw cast iron
• Store under cover to protect from weather and extend life

How do these grates compare to stock factory parts?

Hongso grates match or exceed stock specs for dimension and material, delivering similar sear performance with the added advantage of a porcelain coating for easier cleaning. They are offered as a cost-effective replacement for worn or damaged factory grates and include cross-reference numbers for compatibility checks.

• Meets original size specifications for listed models
• Porcelain finish improves cleanup versus raw cast iron
• Replacement set restores even heat and searing capabilities
• Compatible with many Char-Broil part numbers for straightforward sourcing

Who is this for?
