A carefully selected item! Milled from a 9mm thick steel plate, the actual plate thickness will be about 8.5mm. To prevent rust, it will be shipped in vacuum packaging as shown in the photo. One-sided milling (the back side is black skin, which is rust-resistant) This steel plate takes about 1 to 1.5 weeks to ship in order to keep the price as low as possible. Made in Japan, processed domestically by JFE Steel, known for "Always contributing to society with the world's best technology." Note: Due to price fluctuations and economic conditions, it may be from other domestic manufacturers. This is the maximum size that can be used with your home gas stove or IH. This is a common size used in food trucks for mobile sales. For safety when carrying, we recommend wearing gloves. Brand new, just cut with a laser! Because it's 9mm thick, used by professionals, crepes will be fluffy and chewy! Of course, it's also a steel plate that can be used for barbecues, etc. The thickness is incomparable to commercially available ones, so you can enjoy authentic teppanyaki. The thick plate evenly distributes heat, and the far-infrared effect makes the outside crispy and the inside juicy. The 9mm thick steel plate has not been seasoned (cleaned, heated, coated with cooking oil, and stir-fried with vegetable scraps to remove the iron smell), so please do it yourself. Maintenance is easy: pour water on it while it's hot, scrape it off with a spatula, and apply a thin layer of oil! For storage, wrap it in parchment paper, kitchen paper, or newspaper, and it will last almost indefinitely. Because the steel plate is heavy-duty, it's unlikely to warp from heat. The steel plates we handle are JIS G3101 general structural rolled steel SS400. It will basically be as-is, so please understand that there may be scratches. We sell it at a bargain price, so please refrain from purchasing if you are unable to season the steel plate yourself.
