Pallet racking parts comprise the multiple components that make up the structure of the racking and ensure the proper storage of the loads it holds. In this post, we take a look at the main warehouse racking parts and their function. For reference, we’ll use selective pallet racking due to its extensive variety of components. Nevertheless, structural elements such as beams, frames and crossbars are common to all metal pallet racking.
Industrial rack components can be broken down into fastening elements (posts, beams and frames) and accessories. These accessories, meanwhile, can be classified as those that adapt the structure to the load (special shelf panels, drum/coil beds) or those that reinforce its safety (fall protection netting, locking devices) in addition to that of the facility (shims, sign holders). The following graphic illustrates all the parts that make up a pallet racking: Further below, we explain each of the components in detail.
Basic parts of a pallet racking
These are the main pallet racking parts names and their functions:
Metal parts that form the vertical structure of the racking frame. There are many models of posts available that adapt to the various types of loads, weights and sizes. Each post has a footplate to affix the structure to the warehouse floor.
Metal posts that join the posts diagonally to constitute the structure of the frame. Diagonal struts reinforce the load capacity of the posts and, thus, guarantee the stability of the pallet racking.
Metal structure that serves as the vertical support of the rack. They are formed by two posts and the diagonal struts, footplates and corresponding accessories.
Horizontal metal profiles that are directly attached to the frames. They are used to hold the pallets or support the shelving panels on which the goods are deposited. In racking structures for palletised loads, pallet stops can also be incorporated to prevent the goods from coming loose from the structure.
Shelf panels are the pallet racking components that are supported by the beams in order to hold the load. Depending on the type of merchandise stored, these shelves can be grated, wooden or galvanised metal.
Metal profiles placed perpendicularly to the beam to reinforce the stability of the loads. This part of the racking prevents pallets from accidentally falling (and potentially breaking). It also facilitates the insertion of pallets on the wide side.
Bracing or cross bracing
Metal profiles affixed to the beams to strengthen the pallet racking’s load capacity. Each profile has a tensioner that provides it with the necessary stiffness.
Metal components placed under profiles that stand on uneven flooring to ensure that the pallet racking structure maintains its centre of gravity.
The endplate that connects the post to the beam has a locking device that prevents the beam from accidentally disengaging. As it is welded to the endplate itself, it’s impossible to remove the safety device, which reinforces the safety of the entire structure.
Steel component that joins two posts of different pallet racking modules.
Types of shelving panels
When storing pallets, there are no shelves, per se, as the goods are directly supported by the beams. However, other types of unit loads are deposited on shelving panels. Various types of shelves can be installed in line with the types of goods to be stored:
Shelf panels fitted directly on the beams, without the need to incorporate an additional fastening element to the racking. They’re ideal for housing bulky goods due to their high load capacity.
Fitted directly onto each level of the racking, these shelves usually serve for picking at various levels. These types of shelves are available in several versions (slotted, grooved or perforated) according to the air circulation needs of the product stored.
Wire mesh shelving
Panels formed by electro-welded wire mesh that, supported on the crossbars, reinforce the stiffness of the structure. These shelves guarantee that the automatic sprinklers work efficiently by allowing water to circulate through the shelving.
Chipboard shelves can store all kinds of loads. Based on the size and weight of the goods, crossbars can be added to increase the structure’s load capacity.
Pallet racking safety accessories
Pallet racking parts also include a number of accessories designed to enhance the safety of the goods, the racking structure and, of course, the operator. These are the most common safety accessories:
Pallet racking incorporate protectors to avoid structural damage from accidental blows. These safety elements comprise:
- End aisle protector: fitted to the ends of the frames, where impacts are more probable.
- Post and frame protectors: used to prevent structural damage for pallet racking managed with forklifts.
- Corner protectors: made from folded metal sheets that guard the outer posts when post protectors can’t be directly attached.
- Post reinforcers: useful when it is necessary to protect the post at the base and also at a certain height.
Fall protection netting
Safety element installed on the back of the racking to prevent the accidental fall of goods.
Adapters for irregular loads
Pallet racking feature accessories for tailoring the storage structure to any kind of irregular load. These are the most relevant:
Metal part similar to a crossbar that sits perpendicularly on the beams when storing containers. To ensure that the load remains in place, two supports per container are used, one on the left and the other to the right of the unit load.
Component that makes it possible to store drums and coils. It can consist of two rollers on which the drums turn, enabling liquid to be extracted from them. Alternatively, it can comprise a 2" V-shaped part that provides the support required to hold the load in place.
Accessory used to store reels or other cylindrical elements. This part comes in different configurations, depending on the characteristics of the goods, the size of the load or the function of the rack in the facility.
Pallet racking parts also include elements that don’t exactly form part of the structure but that improve safety in the warehouse and make it easier for users to identify the goods. These are the most standard:
Safe load warning notice
Rectangular PVC accessory containing all the technical characteristics pertaining to the pallet racking. It is affixed to the ends of the racking so that it is visible to operators, technicians and warehouse pickers.
Rectangular markers placed on the ends of the racks (at the beginning and end of every aisle). They display an internal company ID code. This sign makes it easy for operators to recognise which pallet racking module is in that aisle and what type of load is housed there.
Accessory incorporated on the post or beam to facilitate identification of the goods. It can be adhered to the post directly or with an ID card holder.
Quality and safety for every part of a pallet racking
The set of parts that make up a pallet racking ensure their stability, stiffness and load capacity. Likewise, these storage solutions feature a wide variety of elements that adapt the racks to all type of goods and unit loads.
In fact, pallet racking parts such as bracing and crossbars increase the facility’s load capacity. Moreover, with the extensive range of shelving and beams available, these solutions can be customised to meet the needs of any customer. Want to know more about Mecalux’s pallet racking systems?
