A 4-layer metal oven rack is a multi-tiered rack system designed to maximize space and improve efficiency when cooking multiple items at once in an oven. This type of rack is typically constructed from stainless steel or chrome-plated steel, offering durability, resistance to rust, and high heat tolerance. It's especially useful for larger ovens or for those who need to cook several dishes simultaneously.

Key Features of a 4-Layer Metal Oven Rack:

1. Multiple Layers: The 4 layers provide multiple levels where food can be placed, allowing you to cook or bake several items at once without crowding the oven. This is perfect for preparing large meals or baking multiple trays of cookies, pizza, or other baked goods at the same time.

2. Material: As with single-layer racks, 4-layer oven racks are usually made from stainless steel or chrome. These materials ensure the rack is strong enough to support the weight of various dishes and can withstand high temperatures without warping or deteriorating.

3. Space-Saving: The 4 layers allow for the efficient use of oven space, making it especially useful in ovens with larger capacities or for those who cook large quantities. Each layer can hold separate items, helping to keep foods apart and ensuring even cooking and browning.

4. Even Heat Distribution: The design of the rack promotes proper air circulation around the food, ensuring that heat is evenly distributed. This helps achieve consistent cooking results for all the dishes placed on the layers.

5. Adjustable or Fixed Layer Height: Some 4-layer racks allow for adjusting the height of each layer, making it more versatile for different oven sizes and types of food. Others may have fixed levels, but still offer a good range of cooking options.

6. Heavy-Duty and Sturdy: A 4-layer rack is usually built to handle heavier loads. You can place multiple large items or dishes without worrying about the rack bending or breaking.

7. Easy to Clean: Like most metal oven racks, a 4-layer model is typically easy to clean. It can be wiped down after cooking, and some racks are dishwasher-safe. However, food build-up might need occasional deep cleaning.

8. Size: 16/24 Shelf Tray , 4 Feet Height 

Functionality:

• Baking and Roasting: Ideal for baking large batches of cookies, pastries, or roasting meats, as each layer provides ample space while ensuring even heat circulation.
• Grilling or Broiling: The multiple layers allow for different foods to be cooked simultaneously at varying levels of heat, optimizing the oven's heat source.
• Efficient Cooking: For large gatherings or meal prep, a 4-layer rack allows you to maximize oven use, helping to save time and energy by reducing the need for multiple cooking sessions.

Additional Benefits:

• Versatility: A 4-layer oven rack can be used in a wide variety of cooking scenarios—whether you're baking, grilling, or roasting.
• Durable Construction: The metal construction ensures that the rack remains stable and strong even when loaded with multiple trays or heavy dishes.
