Space Productiv Cantilever Racking Systems

Cantilever racking allows you to expand your current warehouse capacity by making the best use of your vertical space. Cantilever is a cost-effective, flexible and safe solution for storing long, heavy, irregular shaped or sheet products. Designed with an open-front profile, it maximises your warehouse’s storage capacity and provides accessibility for storing varying length items.

Cantilever racking is modular in design which means we can design a system bespoke for your needs and which can be easily adjusted or extended in the future to suit the ever changing needs of your business storage requirements.

Our cantilever racking is a heavy duty system made in the UK from hot rolled steel sections. We guarantee our products for 5 years. A full planning and installation service is offered as standard.

What is Cantilever Racking

Cantilever racking is a type of warehouse racking that comprises a series of uprights known as columns, supporting horizontal load supporting arms and tied together with a bracing system located between the uprights so as not to impede access into the load space.

Two of these uprights / columns can form a single rack or starter bay to which single uprights can be added indefinitely to increase the rack length maximizing the space available and providing uninterrupted linear storage along the length of the rack.

Our cantilever racking system can be configured as a single sided rack, alternatively arms can be fitted to both sides doubling the storage capacity of the rack, at a fraction of the cost of a second rack as both set of arms utilize the same column.

Where Are Cantilever Racks Used?

Cantilever racks offer a flexible storage system commonly used for the storage of long items such as timber packs, steel pipes and tubes, timber trusses, beams, a range of sheet material and even scrap vehicles but also for variable length pallets. When standard adjustable pallet racking is unsuitable due to size, shape, length or weight of stored items, cantilever racking can be used, in conjunction with a range of ancillaries and options to create a bespoke storage solution perfectly adapted to almost any storage requirement.

Cantilever racking is often used for the storage of:

  • Timber packs
  • Steel pipes, bars and tubes
  • Sheet materials
  • Scrap vehicles
  • Worktops and laminates
  • Engineering components and materials
  • Extrusion
  • Concrete lintels
  • Pallets & Stillages

Expert Cantilever Racking System Design

Space Productiv are the only SEMA approved manufacturer of hot rolled cantilever racking in the UK, meeting SEMA code of practice, BS 5950 Structural Use of Steel in Buildings and BS 5135 Weldable Steels. Our products have been independently tested and are designed to give a 1.6 times safety factor to mitigate the considerable forces that cantilever can be subject to in an industrial workplace.

Our CE Marked and ISO 9001 certified manufacturing facility is backed by over 30 years of experience and expertise we are committed not only to the highest standards of manufacturing quality, but also to ensuring that your cantilever racking solution is perfectly tailored to your business needs.

We offer a free site survey and design consultation where we assess your products and warehouse management processes alongside the available equipment and space in order to recommend a solution that is not only robustly safe and HSE compliant but also maximises productivity.

Our qualified inhouse structural engineers assess the length of cantilever arms as it relates to your stored items for the potential for tip loading to ensure that there is no possibility of buckling. We calculate the load bearing requirements of the cantilever system and make recommendations about height, strength and spacing. Our specialists will also determine the correct height for your cantilever racking as it relates to fire suppression sprinkler heads, forklift reach and local building codes.

The project provided a 41% increase in covered storage area on site and increased the overall storage capacity by 24%. This meant that Ridgeons was able to consolidate operations from two sites into a single site, saving them over half a million pounds per year and allowing them to eliminate duplication of stock holding and to streamline their supply chain management for further productivity savings.
