Weight capacities can be a tricky thing. We want to ensure that you know exactly what you're buying, and that we've set proper expectations for our products.
Our weight capacities are tested by independent 3rd parties, and rest assured, are not fabricated.
You will notice that there are different weight capacities based upon whether an item is on wheels or not. The reason for this is that the wheels generally will buckle before the shelf will. When putting an item on wheels, those wheels are your limiting weight capacity factor.
For our wire shelving racks, each shelf is tested to hold a maximum of 1.5 times the disclosed weight capacity when NOT on wheels. For your safety, we do not recommend that you load these shelves with the maximum weight.
However, please note that once a wire shelving unit is put on wheels, the weight capacity of each shelf declines significantly. This is because the wheels now become the limiting weight capacity factor, and not the shelf itself. The weight capacity is then calculated by:
total weight capacity of the wheels / by the # of shelves
Should you require a specific weight capacity, or have additional questions, please feel free to contact us, and we'll be sure to answer your questions.
