Choosing expanded metal for a grill grate means balancing strength, mesh openings, panel size, and safe food contact. The options below range from large, heavy-duty sheets to smaller multipacks. Before cooking on any of them, confirm that the metal is suitable for food contact and check whether it has a coating; the product details provided do not establish that every sheet is bare, food-safe steel.

Our Picks: Best Expanded Metal For Grill Grate reviews
1. Kerty 11-Gauge Sheets: Best for Large DIY Grate Projects
This two-pack gives you two large flattened cold-rolled steel sheets, each listed as 48 x 36 inches and 11 gauge. That is a substantial amount of material for a custom grill grate, smoker tray, or several smaller projects. Its size is useful if you need to cut panels to fit a particular grill rather than settle for a standard grate dimension.
The listing describes the mesh openings in two different ways: one section gives 0.6 x 1.2 inches, while another gives 0.5 x 1 inch. It also lists the thickness as both 0.12 inch and 3 mm. These details do not fully agree, so check the current product specifications or ask the seller to confirm the measurements before planning a close-fitting project.
The large panels and heavier stated gauge make this a practical option when rigidity and available material matter. On the other hand, a full sheet may need careful cutting and edge finishing. Confirm food-contact suitability and coating status before using it as a cooking surface, and take care around cut edges.
Pros:
- Includes two large panels for custom sizing
- Listed as 11-gauge cold-rolled steel
- Flattened mesh is intended for BBQ and smoker projects
- Can also be used for other DIY applications
Cons:
- Mesh opening and thickness details differ within the listing
- Large sheets may require cutting and edge cleanup
Verdict: Choose the Kerty set if you need plenty of material and can verify the exact dimensions and food-contact suitability before fabrication.
2. Shapiro Metal Supply 3/4#9 Sheet: Best Single-Panel Option
This flattened expanded-metal sheet measures 24 x 48 inches and is listed as 3/4#9 with a thickness of .110 inch. It comes with two stainless-steel BBQ skewers, which adds a useful accessory if you cook skewered food. The product description also notes that the sheet can be used for BBQ grills and other projects where air, light, or liquid needs to pass through.
Compared with the larger multipacks in this list, this is a straightforward single-panel purchase. Its stated dimensions make it easier to plan around than listings with conflicting size details, though you should still confirm the mesh opening and fit for your grill before ordering. As with any expanded metal, the open pattern will not support every small food item as reliably as a solid or finer-mesh grate.
The included skewers are a bonus, but the listing does not provide details about food-contact suitability or a coating for the sheet itself. Check those points before using the panel as a cooking surface. It is also worth planning for safe handling and finishing if you cut it to size.
Pros:
- Clear 24 x 48-inch panel size
- Listed thickness of .110 inch
- Includes two stainless-steel BBQ skewers
- Flattened expanded metal allows airflow
Cons:
- Only one sheet is included
- Food-contact and coating details are not provided
Verdict: This is a sensible pick if one 24 x 48-inch sheet meets your needs and you value the included skewers.
3. Gisafai 12-Gauge Four-Pack: Best for Multiple Small Panels
Gisafai supplies four steel sheets, each listed as 24 x 24 inches and 12 gauge. The pack can suit a project that needs several smaller panels, replacement sections, or material for more than one build. Its listed uses include ventilation, shelving, fencing, and other DIY work in addition to grill-related applications.
There is a mesh-size discrepancy to note: the title calls it a 3/4-inch grid, while the description gives openings of about 0.91 x 1.97 inches. That difference matters for a grate because it affects which foods the mesh can support. Confirm the actual opening size before buying, especially if you plan to cook small items directly on the surface.
The description calls the sheets resistant to rust and corrosion, but it does not clearly state the finish or establish food-contact suitability. Treat those as points to confirm rather than assume. The four-panel format is more flexible than a single large sheet, but it may not be the right choice if you need one uninterrupted grate-sized surface.
Pros:
- Four sheets offer flexibility for multiple projects
- Each panel is listed as 24 x 24 inches
- 12-gauge steel construction is specified
- Suitable for a range of DIY uses beyond grilling
Cons:
- Mesh opening measurements are inconsistent in the listing
- Food-contact suitability and finish are not clearly stated
Verdict: Consider this pack for several smaller builds, but verify the mesh opening and surface finish before making a grill grate.
4. Gisafai Black 9-Gauge Sheets: Best for Compact Custom Builds
This set includes two compact 24 x 12-inch expanded-metal sheets made from carbon steel. The listing identifies them as 9 gauge and describes them as black. Their smaller format may be easier to work with than a full-size panel if you are making a narrow grate, a small smoker component, or another custom piece.
The product description mentions BBQ use and says the material can be welded or cut. It also advises brushing the sheet with oil before and after use and using nonmetallic grilling tools. However, the listing does not explain what gives the steel its black finish or confirm whether that finish is suitable for cooking. Do not use it as a food-contact surface until that information is clear.
The 9-gauge specification suggests a heavier sheet than the 12-gauge Gisafai option, but the panels are much smaller. Choose this set for compact dimensions rather than for a large grate. Cut edges can be sharp, so handle and finish them carefully.
Pros:
- Two compact panels are included
- Listed as 9-gauge carbon steel
- Can be cut or welded for custom projects
- Product details include basic care guidance
Cons:
- The black finish is not identified as food-safe
- Each sheet is only 24 x 12 inches
Verdict: This set may fit a small custom project, but confirm the black finish is appropriate for cooking before using it as a grill grate.
5. Shapiro Metal Supply 2-Pack: Best for Two Large Panels
This Shapiro Metal Supply set includes two flattened expanded-metal sheets, each listed as 24 x 48 inches and .120 inch thick. The 3/4#9 designation gives you a stated mesh style to compare with the other options, while the two-panel pack offers material for a pair of projects or a spare panel.
Unlike the first Shapiro option, this listing does not mention included skewers. Its key appeal is the two-sheet format and the listed thickness, which may make it a better fit if you need more than one large panel. The supplied product details do not include additional information about the metal’s finish or food-contact suitability, so check before using it for direct cooking.
Because the listing description is brief, confirm the exact dimensions, mesh details, and finish before ordering. It is a practical candidate for a custom grate if its specifications match your design, but it offers less detail to guide a first-time buyer than some of the other choices.
Pros:
- Two large 24 x 48-inch sheets are included
- Listed thickness is .120 inch
- Flattened 3/4#9 expanded-metal design
- Useful when you need a spare or multiple panels
Cons:
- Product details provide little information about finish or care
- Food-contact suitability is not stated
Verdict: Choose this two-pack when you need two large panels and can confirm the finish and grate specifications with the seller.
How to Choose Expanded Metal for a Grill Grate
Check that the metal is suitable for cooking
Do not assume that a steel sheet is ready for direct food contact just because its listing mentions BBQ use. Ask whether the sheet is bare or coated and whether the surface is intended for cooking. A black finish needs special attention because the supplied product details do not identify its coating. If the seller cannot confirm suitability, choose a product with clearer information or use a grate material specifically intended for cooking.
Match the opening size to the food you cook
Expanded metal has open diamond-shaped gaps that let heat and air pass through, but larger openings can allow small foods to fall through. Compare the listed mesh dimensions with your cooking needs, and confirm them when a product page gives conflicting measurements. The size and shape of the openings can matter as much as the panel’s overall dimensions.
Choose a gauge and thickness for your project
Gauge and thickness help describe the sheet’s build, but do not compare a product by gauge alone when listings also provide a thickness measurement. Check both figures, along with the size of your grate and how it will be supported. If a listing gives inconsistent thickness details, clarify them before buying or cutting the sheet.
Measure the grate area before ordering
Measure the inside dimensions of your grill or smoker, including any ledges or supports where the grate will sit. Leave room for the panel to fit without binding, and remember that cutting a larger sheet creates new edges that need attention. A single 24 x 48-inch sheet may suit one design, while multipacks of smaller panels may be easier to handle for separate sections.
Plan for cutting, edges, and upkeep
Expanded metal can have sharp edges, especially after cutting. Use suitable protective gear during fabrication and smooth or otherwise safely finish cut edges before handling or cooking. For products whose instructions recommend it, oiling the surface may help with upkeep, but follow the manufacturer’s care directions and avoid assuming all finishes should be treated the same way.
Consider how much material you actually need
A large two-pack can be useful for multiple builds, but it may be unnecessary if you need only one small grate. Think about whether you want one continuous panel, several smaller panels, or extra material for later projects. The best value depends on how much of the sheet you can use and whether its dimensions match your grill.
Frequently Asked Questions
Is expanded metal suitable for a grill grate?
It can be used for grill and smoker projects, as several product listings state, but that alone does not confirm food-contact suitability. Check the metal’s finish and intended use with the seller before cooking on it.
What mesh opening size should I choose?
Choose an opening that supports the foods you plan to cook while allowing airflow. Smaller foods need closer support than large cuts. Confirm the actual opening dimensions, especially when a listing gives different measurements in its title and description.
Is a thicker expanded-metal sheet always better?
Not necessarily. Thickness is one factor, but the right choice also depends on the panel size, mesh pattern, and how the grate is supported. Compare the stated gauge and thickness, then make sure the sheet fits your design.
Can I cut these sheets to fit my grill?
The product descriptions identify several sheets as suitable for cutting or custom projects. Cutting can leave sharp edges, so use proper safety precautions and finish the edges before installation or handling.
Can I use black expanded metal for cooking?
Only if the seller confirms that its finish is suitable for food-contact use and high-heat cooking. The black Gisafai listing does not identify the finish, so do not assume it is safe for direct cooking.
Do expanded-metal grates let small foods fall through?
They can, depending on the opening size and the food. Check the mesh dimensions before buying. If the openings are too large for your usual food, consider a different grate or a suitable cooking surface designed to support it.
Final Recommendation
For a large custom build, the Kerty two-pack stands out for its generous sheet size and stated 11-gauge construction, but its listed thickness and mesh measurements should be confirmed first. The Shapiro 24 x 48-inch sheet with skewers is a straightforward single-panel option, while its two-pack is worth considering when you need a second large sheet. Whichever you choose, confirm food-contact suitability and finish details before using expanded metal as a cooking grate.
