Pallet racks are also commonly known as high bay pallet racks or industrial pallet racks. They are usually heavy-duty racks and are the most common in various domestic storage rack systems. They are suitable for both small batches of multiple varieties and large batches of fewer varieties. This type of rack is most commonly used in high-bay warehouses and ultra-high-bay warehouses(it can also be used in industrial warehouses and business service equipment).
