17 Inch Cast Iron Grill Grates for Nexgrill Models - Heavy-Duty

In this review of the 17 in cast iron grill grates, the bottom line is simple: these replacement grates are for grill owners who need heavy-duty, heat-retaining cooking surfaces that match a variety of Nexgrill and compatible models. The reviewer found the set delivers solid searing and even heat distribution thanks to the porcelain-coated cast iron construction, while reminding buyers to measure existing parts first to ensure the 17 in x 13 1/4 in halves (total 17 in x 26 1/2 in) will fit their cooker. This is a practical, value-focused replacement rather than a premium custom accessory.

Key Features

• Exact dimensions: Each half measures 17 in x 13 1/4 in and together form a 17 in x 26 1/2 in cooking surface, which helps buyers confirm fit before purchase.
• Durable material: Porcelain-coated cast iron provides strong heat retention and helps produce pronounced sear marks on steaks and vegetables.
• Compatibility: Designed to replace several original part numbers and fits a wide range of Nexgrill 4 and 5 burner models as well as select Charbroil and other brands, reducing the need to search for model-specific parts.
• Easy maintenance: The porcelain enamel finish prevents sticking and allows for easier cleaning when soaked and brushed with a soft tool.
• Safe at high heat: Cast iron construction resists warping under high temperatures when preheated and handled per instructions, offering long-term outdoor use.

Who It's For

This product is well suited for owners of the listed Nexgrill 4 and 5 burner grills who need a direct replacement that restores cooking performance and grill marks. It is also appropriate for owners of compatible Charbroil and other listed models who prefer cast iron grates for better heat retention and searing.

People who should look elsewhere include those who want lightweight or detachable porcelain steel grates, users who prefer nonstick stainless steel options, or anyone who cannot confirm the 17 in x 26 1/2 in size will match their existing supports. Always measure original parts before ordering.

Pros & Cons

Pros

• Excellent heat retention and searing performance from the porcelain-coated cast iron.
• Wide compatibility with many Nexgrill and selected Charbroil models simplifies replacement shopping.
• Porcelain finish reduces sticking and is easier to clean than bare cast iron when maintained properly.

Cons

• Some users report mixed durability outcomes and occasional delamination of the coating over time, so longevity can vary by use and care.
• Cast iron is heavy and requires seasoning and careful drying to maintain performance, which may not suit casual users.
