Durable Material: The wok ring for gas stoves is made of high-quality galvanized iron, which is fireproof, high-temperature resistant, odorless, and reusable for a long period. Safe and Practical: Non-slip gas wok ring with four convex corners, easy to install and disassemble. This structure allows it to fix the wok and make it more stable during cooking without the pan twisting. Higher Energy Efficiency: The gas hob can adjust the distance between the gas stove and the bottom of the pan so that it absorbs and dissipates heat evenly, improving energy efficiency. Strong Functionality: The cast iron of the wok ring is durable and difficult to bend and deform, enough to support the weight of daily cooking utensils, and has a balance of anti-rust and non-slip properties. Compatibility: Size: 14 x 14 cm/5.51 x 5.51 inches, works with most gas stove tops to reduce the size of the gas ring to ensure the moka pot, pan, or wok fits perfectly onto the gas ring.
