Charbrofire Cast Iron Flat Top Griddle for Weber Genesis II 300/600 Series — Matte Enamel, 18.7" Replacement Plate

This Charbrofire matte-enamel cast iron flat-top griddle is a direct replacement for Weber Genesis II 300 and 600 series grills (part 7599), offering a larger, durable cooking surface built for even heat and high-heat searing.

If your Weber Genesis II E-310, S-335, SE-310 or a compatible 300/600 series model needs a replacement flat top, this Charbrofire griddle plate provides a heavy-duty alternative to thin porcelain-coated options. Made from enameled cast iron, it combines the heat retention and searing performance of cast iron with a protective matte enamel finish that resists flaking. The plate is sized to line up with factory grates and works with many Genesis II burners for consistent cooking across the surface.

Will this griddle fit my Genesis II E-310 or S-345 grill?

Yes — the plate is engineered to match the footprint used on a wide range of Genesis II models. It is compatible with many factory part numbers including 7599 and equivalents, so installation is usually straightforward for these grills.

How does the cast iron griddle perform compared with porcelain-coated tops?

The cast iron core stores and distributes heat more effectively than thin porcelain-coated griddles, giving faster searing and a more uniform cooking plane. The matte enamel surface protects the iron beneath but avoids the fragile, easily chipped finishes common to some porcelain products.

• Heavy cast iron offers superior heat retention for searing and browning.
• Matte enamel resists chipping and protects against rust when maintained.
• Even heat across the plate reduces hot and cold spots during cooking.

What are the size, material, and care recommendations?

This replacement griddle is approximately 18.7 inches long and constructed from matte-enamel coated cast iron. To keep it performing and to extend its service life, oil the surface before and after use and avoid metal tools that can scratch the enamel.

• Dimensions: roughly 18.7 inches in cooking length to align with Genesis II grates.
• Material: enameled cast iron for durability and heat stability.
• Care: season or oil regularly, clean with non-abrasive tools, avoid prolonged moisture exposure.

How easy is it to install and replace the original griddle plate?

Installation is typically simple — the plate drops into the grate bay and rests on original support points used by factory griddles. No special tools are generally required, but handling cast iron carefully avoids damage and personal injury due to weight.

• Direct drop-in replacement for compatible Genesis II grates and supports.
• Weighs more than thin plates; lift with two hands to align safely.
• If unsure, compare part numbers or measure existing plate length before purchase.

Who is this for: Home grillers who want a long-lasting flat-top with excellent searing and heat consistency for their Weber Genesis II 300 or 600 series. It’s ideal for cooks who value heavy-duty performance, prefer enameled cast iron over fragile porcelain coatings, and want a straightforward replacement that works with OEM mounting points and common Genesis part numbers.
