1. What is Pallet Racking?
Pallet Racking is a steel structure that is typically used in warehouses for the storage of pallets. It consists of posts, frames and beams.
Space Rescue are one of the few pallet racking suppliers that offer both new and used pallet racking for sale Australia wide.
2. Pallet Racking Dimensions and Sizes
A variety of standard frame heights, bay widths & shelf/frame depths makes this type of shelving suitable for almost any location:
a) Frame heights
b) Beam lengths (or Bay widths)
c) Frame widths (or Shelf depths)
[Note: A frame depth of 838mm suits Australian Standard Hardwood Pallets. Other pallet or skid sizes may work better with a deeper frame and use of Mesh Decks]
a) Overall Length:
This is determined by the number of lengths of pallet racking beams (or clear entry bays) in the run plus the addition of frame thicknesses (or upright width) which is approximately 90mm per frame.
b) Pallet Racking Shelving Material
Choice of Mesh Decks or Pallet Racking Boards
c) Components and Pallet Racking Accessories:
Please refer below for definitions of components and accessories available
Posts or Frames are typically supplied in a pre-Galvanised (Zinc finish) or powder coated in a deep Blue colour. The Beams are typically powder-coated in a bright safety Orange or Blue colour. Other finishes are also available. We also stock 2nd Hand Pallet Racking.
3. Components & Definitions for Pallet Racking
Frames (or end frames) consist of two vertical uprights (or posts or columns) connected by frame bracing.
Bracing is the term given to slim strut like members that are used to join two uprights together in a truss like manner. There are two types; horizontal and diagonal frame braces.
c) Base Plates
Base Plates are found at the bottom of each upright. They are used to spread the vertical point loads imparted by each upright and secure the structure to the floor.
Beams are horizontal members used to directly support the loads imparted by pallets and shelving set-ups.
e) Double Deep Rails
Double Deep Rails are used in Double Deep Pallet Rack and run from the aisle to the rear storage location to help the forklift operator safely and correctly position individual storage units or pallets.
f) Pallet Rails
Pallet Rails run from the aisle to the rear pallet location to help the forklift operator safely and correctly position pallets. These are common in Double Deep structures. (refer to section 5 below)
4. Selection of type of Pallet Racking Storage Structure
Depending upon the nature of the business, either one or a combination of types of pallet storage structure may be employed to optimise your operation.
The following pallet factors that need to be considered when selecting the most suitable storage structure:
- type of pallet
- size of pallet
- weight of pallet
- accessibility of pallet
- commonality of pallet
5. Static Pallet Racking Structures
Static Structures are those Pallet Racking structures where the pallet or stored item does not move after it has been stored.
a) Selective Pallet Racking
Selective Racking is the simplest and least expensive type of space rack, pallet storage structure or warehouse racking solution. It is ideal for use in situations where you require access to each individual pallet. This structure is the most common type of structure used.
In component form, this style of rack simply consists of vertical ‘Frames’ (a frame is made up of two uprights with diagonal cross bracing) and horizontal ‘Beams’.
b) Drive In Racking
Drive In Racking consists of multiple lanes for the storage of multiple identical pallets. It suits warehouses where there are many pallets with a lesser number of SKUs (‘stock keeping units’).
It is one of the most space efficient storage systems available. The reason it is such an effective way to store your pallets is due simply to the reduced number of forklift access aisles to service a high quantity of pallets compared with Selective or Double Deep structures.
Pallets within each lane (or bay, made up of multiple storage levels) need to be identical as you are only generally able to access the pallet that is closest to the aisle. With this system, the forklift is required to drive into a lane to deposit and retrieve pallets from this integrated rail and post structure.
c) Double Deep Racking
Double Deep Racking is recommended for those businesses with a range of SKUs (‘stock keeping units’) that require multiple pallets to fulfill safety stock levels. It is the second most common type of structure used.
As the name suggests, pallets are stored two deep from an aisle and hence the rear pallet may not be accessed until the front pallet (ie. the pallet closest to the aisle) has been removed. Due to pallet commonality, this does not create a problem unless there are stock rotational requirements due to expiry date issues.
This style of rack requires a special forklift with the ability to reach in to the second pallet position. Depending on the type of forklift used, it is sometimes recommended that pallet guide rails be used on the upper levels to assist the forklift operator place and retrieve pallets safely on upper pallet storage levels.
d) Narrow Aisle Racking
Narrow Aisle Racking achieves higher storage to footprint ratios than Selective of equivalent pallet storage capacity. This is primarily due to the narrower aisles which are made possible by the special forklifts and picking machines that are used to service them.
For very tall structures on a large footprint (aka High Bay Warehouses), it is not uncommon for automated cranes to service them. With the economies of scale, the great expense of an ASRS (Automated Storage Retrieval System) with its speed and tireless 24/7 endurability can be justified.
e) Cantilever Racking
Cantilever Racking is a great way of storing long products such as pipes, tubes and long crates. Different products may be stored on multiple arms set on different levels. Support arms are fixed on one end only to provide open access on the aisle side.
Both single and double sided structures are available. More information
f) Vertical Racking
Vertical Racking is a great way of storing long products such as pipes and tubes vertically. Different products may be stored on multiple arms set on different levels. Support arms are fixed on one end only to provide open access on the aisle side.
Both single and double sided structures are available. More information
A sturdy workbench made out of Pallet Racking is called a Pallet Rack Workbench. They can be made in to any length by simply joining bays together.
6. Dynamic Pallet Racking Structures
Dynamic Structures are those racking systems where the product and/or structure moves as part of it’s operation.
a) Push Back Racking
Push Back Racking offers the ‘best of both worlds’ in terms of greater selectivity and a lesser number of forklift aisles. Pallets are stored within this structure by pushing them up individual lanes that consist of a line of gravity rollers.
Unlike Drive-In, different pallets may be stored within the one bay on different levels. ‘FILO’ or First-in, Last-out movement of pallets does not suit product with expiry dates.
b) Flow Through Racking
Flow Through Racking offers several major advantages including dense storage, limited aisle space requirements, good selectivity and excellent stock rotation.
On the contrary, these structures, with their gravity wheel lanes, are more expensive when comparing the cost per pallet storage position.
c) Mobile Racking
Mobile Racking achieves greater storage density whilst maintaining selectivity by moving the rack to create the aisle. Only one aisle space is required for multiple runs.
The aisle space is simply created between racks when needed by separating rows of rack so that a particular location may be accessed.
7. Accessories for Pallet Racking
a) Upright Protectors
Upright Protectors are available in a variety of types that are used to protect the upright from damage (e.g. forklift)
b) Pallet Rails
Pallet Rails run from the aisle to the rear pallet location to help the forklift operator safely and correctly position pallets.
c) Mesh Decks
Mesh Decks are used to provide extra protection for skid or non-standard pallet sizes being used. They are also used when providing shelf storage within pallet rack (boards may also be used).
d) Pallets & Skids
Pallets & Skids are typically constructed from timber and provide a strong stable base for placing products on.
e) Pallet Cages & Stillages
Pallet cages & Stillages are used to contain loose items within the confines of a pallet footprint. They simplify the handling of product.
8. Applications of Pallet Racking
In simple terms, it is shelving for pallets or skids though lower levels are often used for shelving by creating a shelf surface by placing boards or mesh decks on top of the beams (or rails).
With a clean open design and a choice of either board, mesh or steel shelves, Longspan Shelving is surprisingly versatile and may be used for a large variety of applications within warehouse, factory, retail and office environments.
Whilst it is often used in industrial applications, it can also be found in office back rooms storing archive boxes and other paraphernalia.
