The Uniflasy 7638 set is built from solid cast iron with no porcelain coating, which means it absorbs and radiates heat more aggressively than any enameled alternative. Each grate measures 17.5 x 11.9 inches, and the pair spans the full cooking area of the Weber Spirit 300 and Spirit II 300 series, including models like the E310, S310, E320, and E330. The bar thickness gives you enough thermal mass to produce deep sear marks even when you load the grill with multiple steaks at once.

Compatibility extends beyond the Spirit line — these also drop into the Weber Genesis Silver B/C, Gold B/C (2002 and later), and the Genesis 1000 through 3500 series, as well as the SmokeFire EX4 and EX6 pellet grills. The fit is tight and precise, and the grates sit flush against the burner trays without rocking. The matte cast iron finish is porous, so it will grab seasoning quickly on the first few cooks.

There is no non-stick coating to chip, which is a major advantage for high-heat searing. The trade-off is that these grates require dedicated care — oiling after each use and keeping them dry is mandatory to prevent surface rust. If you are willing to maintain cast iron, these will outlast any porcelain-coated grate by years.

The Leship grates are specifically designed for the Weber Genesis 300 series produced between 2007 and 2016, including the E310, E320, S310, S320, EP310, EP320, and the 330 models from 2011 to 2016. Each of the two grates measures 19.5 x 12.9 inches, 0.5 inches thick, and the porcelain coating is applied over cast iron, giving you the searing weight of cast iron with a smooth, rust-resistant enamel surface.

Owners of older Genesis grills often struggle to find aftermarket grates that match the exact 19.5-inch length — most universal replacements are shorter by an inch or more. Leship has matched the OEM fit closely enough that reviewers report a snug drop-in installation with no rattling. The bars are shaped with a slight curve typical of Weber-style grates, which helps channel grease toward the drip tray.

The porcelain coating makes daily cleaning significantly easier than bare cast iron, and it resists the kind of pitting that uncoated grates develop from moisture. Be careful with metal grill brushes — if the bristles scratch through the porcelain, rust can spread underneath the coating. Stick to nylon brushes or wooden scrapers.

This Uniflasy set is made for the Home Depot Nexgrill 4-burner (720-0830H) and 5-burner (720-0888) models, as well as the Expert Grill 720-0789H and Cuisinart CGG-7400. Each grate is 17 x 13.25 inches, and the pair creates a total cooking area of roughly 450 square inches. The matte cast iron finish is left uncoated, which means the grates can reach the same high surface temperatures as the original hardware without any coating to degrade.

The bar spacing is wide enough to allow flame kiss on thick steaks but narrow enough to support chicken thighs and pork chops without sagging. Several reviewers noted that the grates fit with no modification, even on grills that had experienced slight warping of the firebox from years of use. The cast iron is heavy — over 13 pounds for the pair — so the grates stay planted when you slide a spatula under a burger.

Some users reported rust appearing after the second season, particularly in humid climates where grills are stored uncovered. This is the nature of bare cast iron. A quick scrub with a stainless steel brush and a wipe of vegetable oil restores the surface, but if you live near salt air or store your grill outside year-round, consider switching to a porcelain-coated alternative.

The Hongso PCE051 set includes four individual grates, each measuring 19.75 x 6.75 inches, which together cover a 19.75 x 27-inch total cooking area. This configuration is designed to fit Char-Griller gas grills from the 2121, 2123, 2222, 2828, 3001, 3030, 3725, 4000, 5050, 5252, 5650, and 9020 model lines, as well as the King Griller 3008 and 5252. Four-piece grates are easier to handle than a single massive cooking grid and allow for partial replacement if one section wears out.

The porcelain coating is polished and smooth, providing a release surface that requires minimal oiling. The cast iron core retains heat well enough to maintain grill temperature even when you open the lid frequently. The 0.55-inch thickness is moderate — enough to hold heat but light enough to lift with one hand.

Because the coating is glossy, it is more prone to showing scratches from metal spatulas or grill brushes over time. Users who cook high-acid marinades (vinegar-based or tomato-based) should rinse the grates soon after cooking to prevent the acidity from etching the enamel. A nylon brush and warm water are usually sufficient for cleaning.

The Direct Store DC114 set is nearly identical in dimensions to the Hongso PCE051 — each of the four grates is 19.75 x 6.75 inches, and the total area covers 19.75 x 27 inches. It fits the same range of Char-Griller models (2121, 2123, 2222, 2828, 3001, 3030, 3725, 4000, 5050, 5252, 5650, 9020) and King Griller 3008 and 5252. If you need to replace a specific section rather than the whole set, the four-grate layout makes that easy.

The polished porcelain coating provides a slick cooking surface that browns well and resists egg and fish sticking. The cast iron underneath is thick enough to hold a stable temperature across the entire grate surface, which reduces hot and cold spots common in thin wire grates. Cleaning instructions advise against dishwasher use or steel brushes to extend the coating lifespan.

The packaging explicitly warns that cast iron grates can crack during shipping if the box is mishandled. If you receive broken pieces, the seller offers free replacements. Inspect the coating edge-to-edge when you open the box — any missing chips should be reported immediately because exposed cast iron will rust faster than the coated areas.

The QuliMetal 7644 set is the direct replacement for the factory grates on Weber Q100, Q1000, Q1200, Q120, Q1400, and Baby Q models. Each of the two grates measures 17 x 12.7 inches, and the matte cast iron finish is the same material Weber uses on its more expensive Spirit and Genesis lines. For a portable grill that typically ships with thin steel or stamped grates, this cast iron upgrade is a significant performance leap.

The grates are split into two pieces rather than one solid grid, which makes them easier to remove and clean on a small tabletop grill. The surface area is about 214 square inches per grate, providing enough room for four to six burgers or two small steaks on each side. The heat retention of the cast iron helps the small Q-series burners maintain steady temperature even when ambient air is cool or windy.

One recurring note from users is that the bar spacing is wider than the original Weber grates — roughly 1/8-inch larger gap between bars. This is fine for burgers, chicken breasts, and steak, but smaller items like shrimp or sliced mushrooms may slip through. A grill basket or skewers solves this problem without affecting the searing performance.

The Uniflasy 7637 grates are made for the Weber Spirit 200 series gas grills with front-mounted controls — models like the Spirit E210, E220, S210, and S220 from 2013 to 2017. Each grate measures 17.5 x 10.2 inches, and the pair spans 17.5 x 20.5 inches total. The matte porcelain enamel finish sticks with the cast iron core without the glossy slickness of polished coatings, which gives it a more industrial, tool-like feel.

These also fit the Spirit II E210 and E220 models that use the GS4 cooking system, making them a versatile option for Weber owners across two generations of grill design. The bar pattern is the classic Weber five-rod layout with the familiar slight curve, directing grease toward the center channel. The matte finish does a good job of hiding surface scratches that would be obvious on polished enamel.

A few users noticed that the gap between the grates is slightly wider than the original parts — about 1/8-inch extra — which caused small shrimp to fall through on the first use. The porcelain coating is baked on at high temperature and seems resilient to normal grilling temperatures, but sudden thermal shock (pouring cold water on a hot grate) can cause the coating to craze.

The Hongso set is a three-pack of grates, each measuring 16.94 x 8.3 inches, with a total combined width of about 24.94 inches. It is engineered as a replacement for a wide range of Charbroil grills, including the Advantage 4-burner (463343819, 463344015), the Commercial series, the Performance series, the Red Infrared 3-burner, and several Kenmore and Master Chef models. The porcelain coating is polished, giving it a smooth, non-stick surface.

The three-grate layout is common on Charbroil grills where the firebox is split into three burner sections. Each grate sits directly over its corresponding burner, which helps with even heat distribution across the entire cooking surface. The cast iron base retains heat well enough to maintain temperature during mid-cook lid openings, and the porcelain coating resists rust effectively in dry conditions.

Some users reported a slightly tight fit — the extra porcelain coating thickness can make the grates sit a fraction of an inch higher than the original parts. This does not affect cooking performance but may require a small adjustment when closing the lid. The polished surface is also prone to scratching if you use aggressive wire brushes, so a bamboo scraper or nylon brush is recommended for cleaning.

The Direct Store DC104 set is a two-pack of porcelain-coated cast iron grates, each measuring 17 x 13.25 inches. It fits Nexgrill 4-burner models like the 720-0830H and 720-0783E, the Charbroil 463241113 and 463449914, and several Kenmore and Uniflame gas grills. The porcelain coating is polished and glossy, giving it a non-stick surface that resists rust from moisture exposure.

The grates use the same 341-025 and 549-057 original part numbers that many Nexgrill and Expert Grill owners will recognize, so the drop-in fit is straightforward with no cutting or modifying required. The cast iron core is moderately thick — enough to hold grill temperature steady for a standard family cook but not as heavy as premium bare cast iron sets. The coating extends to the edges, which helps prevent rust from starting at the corners where moisture tends to pool.

Several users noted that the grates performed well through the first season but began showing surface rust in the second season, particularly in humid climates. This is common with porcelain-coated cast iron when the coating has microscopic pinholes that allow moisture to reach the base metal. Seasoning the grates with oil after each use, even though they are coated, significantly extends their rust-free life.
