The Weber Slate 36 features a case-hardened carbon steel cooktop that Grillpicker found genuinely resists rust, addressing common durability issues in budget models. It delivers 48,000 BTUs across four independent burners and includes an enclosed cabinet for weather-protected storage. However, the unit costs roughly double comparable mid-range options and requires up to two hours of assembly due to numerous cart panels. Additionally, the built-in digital thermometer reads only one spot and can disagree with infrared measurements by 30-50°F. This griddle fits users prioritizing long-term durability and reduced maintenance, while occasional cooks may prefer cheaper alternatives.

Strengths
  • — Case-hardened carbon steel cooktop is pre-seasoned and marketed as rust-resistant, addressing a common flaw in competitor models.
  • — Built-in digital temperature gauge allows users to monitor cooktop heat without using external tools.
  • — Enclosed cabinet storage keeps propane tanks and grilling accessories protected from weather.
Watch-outs
  • — Premium pricing is approximately double that of comparable mid-range flat-top griddles.

Weber Slate 30 Inch Griddle
Ranked #6 in Best Flat Top Griddles
Weber Slate 30 Inch Griddle
3 sourcesall derived

The Weber Slate 30 Inch Griddle features a pre-seasoned carbon-steel surface and a battery-powered digital temperature display, which TonyTone BBQ found provides reliable readings during active cooking. The Barbecue Lab noted that the unit’s substantial thermal mass allows for consistent heat recovery across its 540-square-inch area, though they discovered visible rust spots after winter storage, indicating that maintenance is required to preserve the finish. Despite these strengths, the electronic ignition can be unreliable and often requires multiple attempts or manual lighting to fire up. Weighing approximately 145 pounds with only one folding side shelf due to propane tank mounting, this heavy griddle fits permanent outdoor kitchens but should be avoided by those seeking portability.

Strengths
  • — Pre-seasoned carbon-steel cooking surface that is marketed as rust-resistant and provides a smooth, non-stick finish.
  • — Built-in battery-powered digital temperature display allows for quick heat checks without separate tools.
  • — Front-mounted grease tray with improved thickness and depth compared to the previous generation Weber griddle.
Watch-outs
  • — Electronic ignition can be unreliable, sometimes requiring multiple attempts or manual lighting to fire up.
  • — Only one side shelf folds down; the other is fixed due to propane tank mounting, increasing footprint width.
  • — Heavy unit weighing approximately 145 pounds makes it difficult to move and not suitable for portable use.

How they stack up

Weber Slate 36" Rust-Resistant Griddle

This griddle features a case-hardened carbon steel cooktop that Grillpicker found genuinely resists rust, addressing the maintenance issues common to the Traeger Flatrock and Blackstone Omnivore 28-inch. It provides 48,000 BTUs across four independent burners, offering more power than the Weber Slate 30 Inch Griddle (36,000 BTUs) but less than the Blackstone 36 Air Fryer Combo (60,000 BTUs).

Weber Slate 30 Inch Griddle

The Weber Slate 30 Inch Griddle includes a battery-powered digital temperature display, whereas the Blackstone models rely on analog dials or lack integrated gauges. It offers less total cooking power (36,000 BTUs) than the Weber Slate 36" Rust-Resistant Griddle (48,000 BTUs), but its pre-seasoned surface aims to reduce initial maintenance compared to the raw carbon steel of the Traeger Flatrock.
