These PETKAO 70-01-273 cast-iron replacement grates are a three-pack of matte-enamel cooking grates designed to restore even heat and searing performance to compatible Dyna‑Glo, Kenmore, and Uniflame grills.

If your original cooking grates are warped, heavily rusted, or missing, swapping them for this set gets your grill back to reliable heat retention and crisp grill marks.

What are these grates made of and how do they perform?

The grates are cast iron with a matte enamel coating that combines the heat-holding of cast iron with easier cleanup and corrosion resistance. The enamel reduces sticking and slows surface rust compared with uncoated cast iron while maintaining strong searing capability.

• Material: heavy-duty cast iron with matte enamel finish for durability and reduced maintenance.
• Performance: excellent heat retention for even searing and consistent cooking temperatures.
• Care: enamel coating allows quicker cleaning; hand wash and dry to prolong life.
• Dimensions: each grate 16 7/16" x 9 1/4"; three grates pack to cover 16 7/16" x 27 3/4" area.

How do I install and maintain these replacement grates?

Installation is usually a simple swap: remove the old grates, position the replacement grates in the same slots, and ensure they sit level and secure. Maintenance requires routine cleaning after use and drying to prevent buildup and corrosion.

• Installation: lift out old grates, align new grates with existing ledges or hooks, and set in place — no special tools needed.
• Seasoning: if desired, lightly oil the enamel surface before first use to improve release; do not overheat empty grates.
• Cleaning: scrape off residue with a grill brush after cooking and hand wash with warm soapy water when cool.
• Storage: dry completely and store in a dry place or under a cover to maximize lifespan.

What does the package include and what should I check before buying?
