Pallet racking main structure and accessories.

1. Pallet racking upright: upright is the vertical support in the pallet racking system, which consists of two uprights connected by bolts through horizontal and diagonal bracing to form the upright frame. The holes on the upright column are spaced 75mm apart, which can support the beam to adjust the height and number of layers up and down with a spacing of 75mm.

2. Pallet racking beam: Pallet racking beam is the horizontal support in the pallet racking system. The beam is welded with hanging clasp at both ends, which can be easily embedded into the holes of the upright, and the beam is connected to the upright frame to form a whole frame to play a solid role. The beams are available in various sizes and thicknesses, depending on the load capacity and the size of the pallets stored, and are usually set at 2700mm long for two pallets per level. Pallet racking with step beams or box beams, equipped with support beams or wire decking will be safer to use. Holes are reserved on the hanging clasp of the beam for installing safety pins. The beam with safety pins installed is not easy to fall off, which improves the safety performance of the pallet rack.

3. wire mesh decking: wire deck is a mesh deck made of welded wire, the mesh is usually 50 * 50mm or 50 * 100mm two options, wire deck bottom welded four reinforcing rib, both sides bent on top of the beam of the rack, when the goods are not used pallets and placed directly on the rack storage will not fall, helping to prevent goods from falling from a height to occur It helps to prevent cargo from falling from high places and effectively protects the personal safety of warehouse workers. The metal wire deck is available in galvanized and powder coated finishes for you to choose from.

4. Pallet rack upright protector: upright protector can effectively protect the rack upright from forklift impact or reduce the damage caused to the upright due to forklift impact, thus avoiding serious safety accidents such as deformation of the rack or even the collapse of the rack. Rack upright protectors are made of plastic and steel, plastic upright protectors are affordable and practical, steel upright protectors are stronger and more durable and can be reused.

5. Support beam: The support beam spans across the rack beam, further enhancing the stability of the rack. Usually each layer is equipped with five support beams, often used in conjunction with the plywood, which can improve the bearing capacity of the plywood.

6. Row spacer: row spacer is used to connect one set of racking system with another set of racking system parallel to it, which helps to improve the stability of the racking system.

To learn all about pallet racking parts, please read our article “Pallet Racking Parts“.

Pallet rack consists of starter bay and add-on bay, usually the first set of rack at the end is the starter bay, each set of racks added later will share upright frame with the previous set of racks, such rack is called add-on bay, so the difference between starter bay and add-on bay is that starter bay has one more upright frame than add-on bay. Generally speaking, the starter bay plus add-on bay structure is more stable and safe than the single starter bay structure, and the starter bay plus add-on bay structure can save you more cost because the add-on bay has one less upright frame.

Considerations for choosing a warehouse racking system.

Before designing a pallet racking system, the factors you need to know include: warehouse dimensions, total number of pallets, weight per pallet load, pallet size, type of forklift, FIFO or FILO storage method.

Warehouse dimensions: It is best for you to have a clear layout of your warehouse, including parameters such as the length, width, height, and location of wall columns, so that you can plan clearly when designing your racking system, avoiding obstacles as well as designing the right height of the rack. Reasonable design to maximize the use of storage space.

Total number of pallets: The number of pallets that need to be stored in the whole racking system. Make a clear count in order to confirm the number of racks needed.

Load capacity of each pallet: Calculate the load capacity of each pallet to determine the load capacity of each level of the racking system. Take selective pallet racking as an example, usually two pallets are placed on each level, if the load capacity of each pallet is one ton, then the load capacity of the racking should be designed to not less than two tons per level.

The size of the pallet: the size of the pallet will directly affect the design of the length and width of the racking. Taking the standard 1200*1000mm pallet as an example, no additional space is needed except for the 100mm safe operating space between the rack upright and the pallet and the pallet in advance, so the length and width of the pallet racking will usually be set at 2700mm and 800mm.

Whether the stored goods are perishable or not: If the stored goods are food products with a short shelf life, the goods turnaround time needs to be taken into account in the design, and the racking system with FIFO storage method is preferred.

Type of forklift: The type of forklift is also something you need to consider. What type of forklift is being used in your warehouse or do you have plans to purchase a new one? Different racking systems use different forklifts. For example, narrow aisle racking systems require narrow aisle forklifts; double deep racking systems require articulated forklifts; and selective racking systems simply require regular forklifts.

FIFO or FILO storage method: Different racking systems use different access methods, so the turnover efficiency is different. For goods requiring faster turnover efficiency or shorter shelf life, you should choose FIFO racking system; for goods with longer storage period and longer shelf life, choosing FILO shelving system is appropriate, which will save your storage cost.

Pallet racking identification.

Teardrop pallet racking system.
