We know it can be quite a daunting task starting a new warehouse fitout. In our next few blogs, we will be addressing some of the most common areas that our customers get stuck on. This week, we will be looking at the importance of understanding your load layouts and capacities for safe and cost-effective storage. We understand how important it is to get the right mesh deck for the job. Improper selection could cause deck failure which could damage your product or cause serious injury to one of your warehouse operatives.
What do we mean by load layouts and capacity?
When you are planning out your new warehouse space, it is vital that you know what you will be storing. All the top health & safety organisations like SEMA will expect to have the weight loading capacities detailed on load notices at the end of each run of racking. The main things that need to be considered to understand you load capabilities are:
- The size and shape of the goods
- If they are palletised or not
- weight of the goods
- if the goods will be stored spanning or in between the beams
A combination of these factors will dictate the load layout and ultimately the attributes required of a mesh deck to safely store the goods. So, let’s get onto some of the different load layouts that you may encounter…
Uniformly Distributed Load (UDL):
A Uniformly Distributed Load is a load that is spread across both beams and over the full surface of the mesh deck. If the goods are palletised this will normally mean the mass is uniformly distributed. In other terms, the mass of the load remains uniform throughout the depth of the bay.
It is important to consider whether the weight would be stored on or between the beams. A between the beams load will put more stress on the mesh deck. If the load you are looking to hold has a large mass, then you may need additional support bars. Depending on the size of the load, you may need to increase the mesh diameter from 4mm to 4.5/5mm. These alterations will cause the price to increase. This is why it is important you know what is being stored so that you don’t end up with an over engineered solution.
A line load layout has its weight distributed in a focused line. A good example of a line load is any products that are being stored on a stringer pallet. This type of pallet is identifiable by its 2 bottom deck boards that contact the mesh. A load layout such as this may benefit from additional support bars to prevent unwanted deflection of the mesh deck that could lead to failure.
A concentrated load is any static load which is not uniformly distributed across the entire surface of the deck. An example of this would be, the storage of liquid-filled containers in the centre of the mesh deck. The full bearing of the weight only falls within the area occupied by the object. A Load Layout such as this may require a thicker wire, stronger support bars or a different aperture configuration.
A point loaded deck is any static load that has a concentrated weight focused at a key point on the surface of the deck. A common example of point loading are stillages that have four feet on their base. This weight is heavily concentrated at these points, and that can cause deflection in the deck. This will make the stored product dangerously unbalanced and unsupported. The location and the addition of extra support bars, or changing the wire thickness can all counteract point loading.
