The boltless construction and pre-assembled frames with feet make installation fast and straightforward – simply slot the beams into the uprights and secure them with the supplied safety locking pins and drop in the chipboard shelves. The shelves are fully adjustable in 50mm increments, providing flexibility to accommodate a wide range of product sizes. The system can also span over ground-stored goods, including pallets, meaning a bottom shelf is not always required.
Each bay offers a total load capacity of up to 4000kg, with individual shelf levels rated up to 800kg UDL. For 900mm and 1200mm deep bays, chipboard support beams are supplied as standard; please refer to the specification in downloads for full details.

Full details on weight loading can be seen in the weight loading tables in our downloads section.
Weight capacity depends on multiple things on your racking layout such as
– Height to the top of the first beam
– Level type (heavy duty or extra heavy duty)
– Bay size (including level length and depth).
Extra Heavy Duty options provide chipboard supports to enhance the weight loadings on 900mm and 1200mm deep options. Other depths the wight capacity remains the same.
Chipboard shelves are ideal for general dry storage and provide a smooth strong surface for everyday items.
Galvanised shelves are suitable for damp or cold conditions and can be wiped clean if you are storing spillable goods.
Yes, you can buy extra components to extend or adjust your longspan shelving.
Additional levels can be added at any time and are fully adjustable in 50 mm increments, allowing you to change the height to suit your storage needs.
Frames are supplied pre built and can be used to create new bays that connect to your existing system.
You can also purchase beams individually, along with D bar dividers for vertical storage, giving you plenty of flexibility to expand or reconfigure your setup.
When planning your space, remember that the beam length shown on the site is the clear internal opening. Once you add the frames, the total bay width increases by 50mm per frame. So a bay’s true width is the beam length plus the extra frame allowance. Measure your space first to ensure the full bay width will fit comfortably.
If you are purchasing multiple bays then you will need to consider that where bays are joined they will be sharing a frame, So be sure to only account for one lot of 50mm every time a frame is joined.
The Product Builder allows you to create a full run of longspan shelving, from a single bay up to five connected bays, all with your chosen sizes and number of levels.
The Add on section is for buying individual extension bays only. These come with one frame and are designed to attach to an existing run.
So use the Product Builder to plan a complete run of up to five bays, and use the Add on section when you want to add extra bays later.
The system is free standing and sturdy but can be fixed to the floor if needed. Assembly is quick because the frames arrive built and you simply slot in the beams and chipboard, though we recommend two people.
Load notices and regular racking inspections are required for safety and legal compliance, helping prevent overloading, collapse, and injury while meeting HSE and SEMA standards.
To keep your shelving safe, install it correctly, stay within load limits, inspect it regularly, repair damage quickly, and keep the area clean and tidy.
Mecalux shelving is not compatible with other manufacturers and should only be used with matching components.
