More Details on Our Top Picks
13 x 17 Cast Iron Cooking Grate for Nexgrill, Charbroil, Expert Grill, Cuisinart, Kenmore, Uniflame, and More
This cast iron grate set stands out for its compatibility across multiple brands like Nexgrill, Charbroil, and Cuisinart, making it a versatile upgrade for many existing grills. Its durable cast iron ensures even heat distribution, which can improve cooking results compared to thinner or less robust options. However, it requires regular maintenance—like oiling and drying—to prevent rust, adding some upkeep effort. Compared to the stainless steel options, cast iron offers superior heat retention but is more prone to corrosion if not properly cared for. The inclusion of two grates adds value for those wanting to replace both at once, but handling requires care to avoid cracking or damage. Ideal for grill owners seeking durability and broad compatibility, willing to invest in proper maintenance.
Pros:- Compatible with multiple grill brands and models
- Durable cast iron for even heat distribution
- Includes two replacement grates for convenience
Cons:- Requires regular maintenance to prevent rust
- Handle with care to avoid cracking or damage
Best for: Grill owners needing a durable, multi-brand compatible grate with long-term heat retention
Not ideal for: Casual users who prefer low-maintenance, rust-resistant materials or those hesitant about regular seasoning
- Dimensions:17″ x 13 1/4″ each, 17″ x 26 1/2″ total
- Material:Cast iron
- Package:2 Pack
- Original Part Numbers:341-025, 549-057, 13000123A0, 13000394A0, 55-09-152
Our verdict“This cast iron grate set is best for grillers who prioritize durability and versatility, and are prepared for ongoing maintenance.”
QuliMetal Grill Grates for Weber Spirit 300 and GS4 Spirit II 300 Series
This set of stainless steel grates offers a solid upgrade for Weber Spirit 300 and Spirit II 300 series grills, providing enhanced durability and rust resistance compared to original porcelain-coated steel. Its seamless fit and even heat distribution make it a reliable choice for consistent cooking results. Compared to the cast iron options, these stainless steel grates require less maintenance and won’t rust easily, but they may not retain heat quite as effectively for searing. The slightly larger dimensions (17.4″ x 11.7″) ensure a generous cooking surface, though they are incompatible with some older Weber models like the Genesis Silver A. The premium price reflects their quality, making them a worthwhile investment for those seeking longevity. This pick is ideal for Weber owners wanting rust-resistant grates that last for years without much fuss.
Pros:- Durable, rust-resistant stainless steel construction
- Designed for even heat distribution
- Seamless fit for multiple Weber models
- Long-lasting quality
Cons:- More expensive than basic steel grates
- Not compatible with some older models
Best for: Weber grill owners seeking durable, rust-resistant grates with easy maintenance
Not ideal for: Owners of older Weber models like Genesis Silver A, or those seeking maximum heat retention for searing
- Dimensions:17.4″ x 11.7″
- Material:Food-grade stainless steel
- Number of pieces:2
- Compatibility:Weber Spirit 300, Spirit II 300, Spirit 400 series

Hinged 18-inch Replacement Grill Grate for Weber Charcoal Grills
This stainless steel hinged grate enhances Weber 18-inch charcoal grills with a two-zone cooking system and a large hinged opening, making charcoal addition and ash removal straightforward. Its durable 304 stainless steel construction offers long-lasting performance, especially compared to fixed grates that can be less flexible. The hinged design simplifies fuel management, particularly during long cooks or tailgates, but the weight of stainless steel can make handling more cumbersome. It’s solely compatible with 18-inch Weber kettles, limiting its broader application. When compared to flat grates like the cast iron set, the hinged feature provides a significant convenience boost for managing charcoal. This upgrade suits charcoal enthusiasts who value flexible cooking zones and easy access.
Pros:- Durable stainless steel with corrosion resistance
- Two-zone cooking design for versatility
- Large hinged opening for easy charcoal addition
- Easy to install and remove
Cons:- Heavyweight due to stainless steel
- Limited to 18-inch Weber models
Best for: Dedicated Weber charcoal grill users seeking a flexible and easy-to-manage grate
Not ideal for: Owners of larger or different-sized grills, or those preferring lightweight options
- Material:304 Stainless Steel
- Size:18 inches
- Design:Hinged, 2-Zone
- Compatibility:Weber 18-inch kettle grills
Our verdict“This hinged grate is ideal for charcoal grillers who want flexible cooking zones and simplified fuel management.”
SUS304 9mm Stainless Steel Grill Grates for Ninja FlexFlame PG300 Series, Set of 2
Designed specifically for Ninja FlexFlame PG300 series grills, these heavy-duty SUS304 stainless steel grates excel in durability and heat retention. Their 9mm thick bars provide robust support and excellent heat conduction, resulting in evenly cooked food. Compared with more general stainless steel grates, their tailored fit for the PG300 series ensures a snug, secure placement. However, this specificity limits their compatibility, making them less ideal for other grill models. Their weight can be a drawback for some users, especially during handling or cleaning. Still, for owners of the PG300 series, these grates promise longevity and consistent results. This upgrade makes the most sense for dedicated Ninja grill users seeking heavy-duty performance.
Pros:- Heavy-duty SUS304 construction for durability
- Excellent heat retention for even cooking
- Specifically designed for PG300 series for a perfect fit
Cons:- Heavy, may be cumbersome to handle
- Limited compatibility outside PG300 series
Best for: Ninja PG300 series owners wanting a durable, high-performance upgrade
Not ideal for: Owners of other grill brands or models, or those preferring lighter, less robust grates
- Material:SUS304 stainless steel
- Bar Thickness:9mm
- Number of pieces:2
- Compatibility:Ninja FlexFlame PG300 series
Our verdict“This set is best for Ninja PG300 grill owners seeking rugged, heat-retentive grates built for long-term use.”
Onlyfire 2-in-1 Cast Iron Grill Grate Replacement for Weber Gourmet BBQ System
This cast iron set offers a dual-grate approach—a large main grate and a smaller sear grate—designed specifically for Weber’s 22.5-inch Gourmet BBQ System. Its cast iron construction ensures excellent heat retention and even searing, elevating grilled steaks and vegetables alike. The inclusion of a separate sear grate provides added versatility over standard single-piece replacements. However, its heavyweight nature makes handling more difficult, especially when cleaning or repositioning. Regular seasoning is required to prevent rust, adding a layer of ongoing maintenance. Compared to simpler steel or stainless steel grates, this set excels in high-heat searing but demands more care. This upgrade makes sense for serious grillers who want professional searing and a versatile setup.
Pros:- Durable cast iron for excellent heat retention
- Provides both large surface and searing capability
- Easy to handle with side handles
Cons:- Heavy and cumbersome to handle
- Cast iron requires regular seasoning to prevent rust
Best for: Grill enthusiasts focused on searing and multi-zone cooking in Weber kettles
Not ideal for: Casual users or those seeking lightweight, low-maintenance options
- Part 1 Diameter:21.5 inches
- Part 2 Diameter:11.8 inches
- Material:Cast iron
- Compatible Grills:Weber 22.5-inch Kettle, Performer
Our verdict“This cast iron duo is perfect for serious Weber grillers seeking professional searing and versatile cooking options.”
QuliMetal 7638 7639 Grill Grates Replacement for Weber Spirit 300 Series and Genesis Models
This set of heavy-duty cast iron grates stands out for delivering superior heat retention and durability, making them ideal for achieving that perfect sear on steaks or burgers. Compared with the stainless steel options like the SUS304 grates, cast iron provides more consistent and intense heat, which can elevate a home grill to restaurant-quality results. However, cast iron requires regular maintenance to prevent rust and is heavier to handle, which might be a drawback for some users. These grates are compatible with a broad range of Weber models, making them a versatile upgrade for serious grillers seeking longevity and performance.
Pros:- Excellent heat retention for high-quality searing
- Durable cast iron construction offers long lifespan
- Compatible with multiple Weber models for versatility
- Provides even heat distribution for consistent cooking
Cons:- Requires regular seasoning and maintenance to prevent rust

Not ideal for: Casual grillers or those who prefer low-maintenance options, as cast iron needs regular seasoning and rust prevention.
- Compatibility:Weber Spirit 300 Series, Spirit II, Genesis 1000-3500, SmokeFire EX4/EX6
- Material:Cast iron
- Dimensions:17.5 x 11.9 inches per grate, total 17.5 x 23.8 inches

Our verdict“This pick is perfect for dedicated grillers seeking a durable, high-performance upgrade for professional results, provided they are willing to care for cast iron.”
SUS304 7mm Stainless Steel Grill Grates for Ninja FlexFlame PG300 Series – Set of 2
This pair of SUS304 stainless steel grates offers a robust, low-maintenance alternative to cast iron, making them ideal for users who want a durable and corrosion-resistant upgrade. Their excellent heat retention ensures reliable searing, comparable to the cast iron option but with less upkeep. Compared to the heavier cast iron, these stainless steel grates are lighter and easier to clean, though they are compatible only with the Ninja FlexFlame PG300 series, limiting versatility. The set’s durability makes it suitable for frequent grilling, but the limited compatibility means it’s not a universal solution.
Pros:- Food-grade SUS304 stainless steel resists rust and corrosion
- Excellent heat retention for searing steaks and burgers
- Easy to clean and maintain over time
- Lightweight compared to cast iron options
Cons:- Limited to specific grill models, reducing versatility

Best for: Owners of the Ninja FlexFlame PG300 series seeking a long-lasting, corrosion-resistant upgrade with minimal maintenance needs.
Not ideal for: Grillers with different models or those seeking a more universal, heavy-duty searing surface, as these are specific to the PG300 series.

This stainless steel grate for 22-inch kettles introduces the innovative EasySpin mechanism, allowing precise manual rotation, which can be a game-changer for managing heat zones during grilling. Compared with basic fixed grates like the cast iron or stainless steel sets, the EasySpin offers better control, crucial for delicate foods or multi-zone cooking. Its hinged opening facilitates adding charcoal mid-cook without removing food, a major convenience over fixed designs. While manual operation means it’s not automatic, the robust 304 stainless steel construction ensures long-lasting resistance to rust. This grate makes the most sense for those who frequently cook with charcoal and want a flexible, easy-to-manage setup.
Pros:- Allows precise control with EasySpin rotation for zone management

Factors to Consider When Choosing Grill Grate Upgrade
Choosing the right grill grate upgrade involves several key factors that affect your grilling experience. Beyond just material and size, consider how much maintenance you’re willing to perform, your budget, and the types of food you cook most often. A good upgrade should enhance heat retention, prevent rust, and fit your specific grill model. Understanding these broader considerations can help you avoid common pitfalls like purchasing incompatible or low-quality grates that may deteriorate quickly.Material Durability and Maintenance
Materials like cast iron and stainless steel each have their pros and cons. Cast iron offers excellent heat retention and searing ability but requires regular seasoning and rust prevention. Stainless steel, on the other hand, resists rust and is easier to clean, making it ideal for low-maintenance needs. Your choice should align with how much effort you’re willing to invest in upkeep and how long you want your grate to last.
Size, Compatibility, and Fit
Ensuring your new grate fits your specific grill model is critical. Measure your existing grate carefully and compare it with product specifications. Many manufacturers offer model-specific options, but universal sizes can also work if measurements align. An ill-fitting grate can lead to uneven cooking and potential safety issues, so double-check compatibility before purchasing.
Heat Retention and Distribution
Good heat retention and even distribution are essential for consistent grilling. Cast iron tends to outperform other materials in this area, making it a favorite for searing steaks or cooking delicate foods evenly. Stainless steel options often have decent heat transfer but may require preheating longer. Think about your preferred cooking style when choosing a material that optimizes heat management.
Price and Long-Term Value
While high-end grates cost more upfront, they often justify the expense through longer lifespan and better performance. Cheaper options may seem attractive but can degrade quickly or require frequent replacement. Balance your budget with the expected durability and performance to find a grate that offers the best value for your investment.
Ease of Cleaning and Maintenance
Some materials and designs make cleaning easier, saving you time after each grilling session. Stainless steel grates typically wipe clean with less effort than seasoned cast iron, which needs regular oiling and careful cleaning to prevent rust. Consider how much effort you’re willing to put into upkeep, especially if you grill frequently or in adverse weather conditions.
Frequently Asked Questions
Can I use a different material grate on my existing grill?
Yes, many grill grates are compatible across various brands and models, especially if they are universal sizes. However, it’s important to verify the dimensions and mounting compatibility before purchasing. Using a different material can offer benefits like better heat retention or easier cleaning, but an ill-fitting grate can cause uneven cooking or safety issues. Always measure your existing grate and compare it with the new option to ensure a proper fit.
How often should I replace my grill grate?
The lifespan of a grill grate depends on material, usage, and maintenance. Cast iron grates may last many years if properly seasoned and maintained but can rust if neglected. Stainless steel tends to last even longer with minimal upkeep. Signs it’s time to replace include warping, excessive rust, or damage that affects cooking performance. Regular inspections can help you determine when a replacement is needed to maintain optimal results.
Is a hinged grate worth the extra cost?
Hinged grates offer convenience, especially for flipping or adding charcoal without removing the entire grate. They can save time and prevent accidental spills. However, hinges may limit compatibility with certain grill sizes or reduce overall grate surface area. If you frequently cook foods that require flipping or prefer ease of access, a hinged model can be a valuable upgrade. For occasional grilling, a fixed grate might suffice and be more affordable.
Should I prioritize heat retention or ease of cleaning?
This depends on your grilling style. If you cook high-temperature foods like steaks or sear burgers often, heat retention should be a priority, favoring cast iron or thicker stainless steel. For those who grill more casually or want minimal maintenance, stainless steel offers easier cleaning and corrosion resistance. Balancing these factors based on your typical cooking habits will lead to a more satisfying upgrade.
What size grill grate should I buy for my grill?
Measuring your existing grate is the most reliable way to determine the correct size. For universal options, check the product specifications carefully to match your grill’s dimensions. Keep in mind that slightly larger or smaller grates might fit with minor adjustments or mounting brackets, but a perfect fit ensures even heat distribution and cooking. When in doubt, consult your grill’s manufacturer guidelines or customer support for recommended sizes.
Conclusion
For most casual grillers seeking a balance of performance and ease of maintenance, the 13 x 17 Cast Iron Cooking Grate offers outstanding heat retention and durability. Those prioritizing long-term rust resistance and low upkeep should consider high-quality stainless steel options like the SUS304 Grates. If convenience and quick access are key, hinged models such as the Hinged 18-inch Replacement make a smart choice. Beginners or infrequent grillers might prefer simpler, more affordable options, while enthusiasts focused on searing and precise control may invest in premium cast iron. Whatever your needs, this roundup provides a range of options to upgrade your grilling game in 2026.
