Warehouse Shelving Units

 Warehouse Shelving Units: A Comprehensive Guide for Suppliers and Users
 Introduction
Warehouse shelving units play a crucial role in the efficient organization and storage of goods within warehouses. As a supplier who has been in the business for many years and has exported shelving units to various Asian countries and regions including Hong Kong, Taiwan, Malaysia, Thailand, Japan, South Korea, and Singapore, I have gained valuable insights into the different types, features, and considerations when it comes to these essential storage solutions. In this guide, we will explore the world of warehouse shelving units in detail, from the basic types available to the factors to consider when choosing the right ones for your specific needs.
 Types of Warehouse Shelving Units
 Selective Pallet Racking
This is one of the most common types of warehouse shelving. It consists of upright columns connected by horizontal beams. Pallets can be easily inserted and removed from the beams, allowing for quick access to stored items. The height of selective pallet racking can vary depending on the warehouse's requirements, with some installations reaching up to several stories. This type is ideal for general storage of palleted goods in warehouses where frequent retrieval and storage of different products are needed. For example, in a distribution center handling a wide range of consumer goods, selective pallet racking enables workers to quickly pick and place items as orders come in.
 Drive-In Racking
Drive-in racking is designed to maximize storage density. It allows forklifts to drive into the racks, where multiple pallets can be stored in a single row. This type is suitable for warehouses with high inventory turnover of the same or similar products. For instance, a large food storage facility might use drive-in racking for storing canned goods, as they can efficiently stack pallets one behind the other, increasing the amount of stock that can be stored in a given area. However, it requires careful planning as it limits access to individual pallets once they are placed deep within the rack.
 Drive-Thru Racking
Similar to drive-in racking, drive-thru racking also allows forklifts to drive through the racks. It provides even greater storage capacity as there is no need to leave an aisle between the rows of pallets. This type is typically used in large distribution centers where high throughput is required, such as in automotive part warehouses where a continuous flow of goods needs to be managed.
 Cantilever Racking
Cantilever racks are often used for storing long or bulky items like pipes, lumber, and steel beams. They consist of horizontal arms extending from vertical posts. This design provides easy access to items on the ends of the arms, making it convenient for loading and unloading. In a construction materials warehouse, cantilever racks are essential for storing long steel bars and wooden planks.
 Mobile Racking
Mobile racking systems use a rail system and motorized mechanisms to move the racks along the tracks. This type saves floor space as only one aisle needs to be maintained at a time. When a particular rack is in use, the other racks can be moved aside. It is beneficial for warehouses with limited space and high storage needs, such as in small manufacturing facilities where every square foot counts.
 Factors to Consider When Choosing Warehouse Shelving Units
 Load Capacity
One of the primary considerations is the load capacity of the shelving units. You need to determine the weight of the items to be stored on each shelf. For pallets, the load capacity of the racking system must be able to support the weight of the pallet along with the goods it holds. Overloading can lead to structural failure and safety hazards. For example, if you plan to store heavy machinery parts on your shelves, you need to ensure that the shelving can handle the significant weight.
 Height Requirements
The height of your warehouse space will dictate the type of shelving you can use. Some warehouses have limited ceiling height, so lower-profile shelving options like selective pallet racking may be more suitable. In contrast, taller warehouses can accommodate drive-in, drive-thru, or high-density racking systems to make the most of the vertical space.
 Accessibility
Think about how often you need to access the stored items. If you have a large volume of inventory but don't need frequent access to individual items, drive-in or drive-thru racking might be acceptable. However, if you require quick access to a wide variety of products, selective pallet racking would be a better choice.
 Material of Construction
Shelving units can be made from different materials such as steel, wood, or plastic. Steel is the most common and durable option, suitable for heavy-duty applications. Wood may be used for lighter storage needs in some cases, but it has limitations in terms of strength and durability compared to steel. Plastic shelving is often used for storing non-corrosive and lightweight items.
 Space Constraints
The available floor space in your warehouse is crucial. If you have limited space, mobile racking or compact storage systems can help you maximize the use of your area. On the other hand, if you have ample space, you can opt for larger, more open racking systems.
 Installation and Maintenance
 Installation
Proper installation is essential to ensure the safety and functionality of the shelving units. It is recommended to have professional installers handle the setup, especially for more complex racking systems like drive-in or mobile racking. They will ensure that the racks are level, the bolts are tightened correctly, and the system is stable. For example, incorrect installation of selective pallet racking can lead to instability, potentially causing damage to the racks and the goods stored on them.
 Maintenance
Regular maintenance is necessary to keep the shelving units in good condition. Inspect the racks for any signs of wear and tear, such as bent beams or loose bolts. Clean the shelves regularly to prevent the accumulation of dust and debris that could affect the performance of the racking system. Lubricate moving parts, if applicable, to ensure smooth operation, especially in mobile racking systems.
 Frequently Asked Questions (FAQs)
 Q: How do I calculate the load capacity of my warehouse shelving?
A: To calculate the load capacity, first determine the weight of the pallet and the items it will carry. Then, check the manufacturer's specifications for the maximum load per shelf or per bay of the racking system. Make sure the total weight does not exceed this limit.
 Q: Can I customize my warehouse shelving to fit my specific needs?
A: Many suppliers offer customization options. You can work with the manufacturer to adjust the dimensions, load capacity, and even the design of the shelving to meet your unique requirements.
 Q: How long do warehouse shelving units typically last?
A: With proper maintenance, steel warehouse shelving units can last for 10-15 years or more. However, factors like usage frequency, environmental conditions, and load handling can affect the lifespan.
 Q: Are there any safety regulations regarding warehouse shelving?
A: Yes, there are safety standards set by organizations like OSHA (Occupational Safety and Health Administration) in the United States. These standards cover aspects such as load capacity, installation, and regular inspections to ensure a safe working environment.
