The BiGDUG Heavy Duty Garage Shelving Unit takes third place in this guide, and it is the listing here that keeps its own arithmetic straight. The blue four-tier bay is claimed at 450 kg per shelf and 1,800 kg per bay, and 450 multiplied by four really does come to 1,800 — the bay total divides cleanly by the shelf count in a way that several other listings do not manage.

Where it wobbles is the spec table rather than the sums. The "Shelf Thickness" field reads 50 Millimetres, while the bullet text describes 6.5 mm thick MDF decks, and 50 mm is also the figure the listing uses for how far apart the shelf levels adjust. The capacity field reads "Minimum weight: 450 kg", and "Number of Items" says 1 while "Unit Count" says 4.0. Everything on this page is taken from the Amazon listing and its customer reviews — we have not handled or tested the shelving ourselves.

## Questions people ask

**How much weight does each shelf take?**

The BiGDUG listing states 450 kg per shelf and 1,800 kg per bay as a uniform distributed load. That means the weight is spread across the shelf, not concentrated in one spot.

**Is the 1,800 kg figure the weight of the unit?**

No. The listing puts the unit's own Item Weight at 54 kg. The 1,800 kg is the bay's load rating, and it matches four shelves at 450 kg each.

**How thick are the shelves?**

The bullet text says 4 tiers of 6.5 mm thick MDF with steel supports. The spec table's "Shelf Thickness" field reads 50 Millimetres, which is the same number BiGDUG gives for the height adjustment — shelf levels move up or down every 50 mm.

**Do I need tools to put it together?**

BiGDUG describes a boltless design that taps together with a rubber mallet, with no bolts, screws or power tools required.

**Can it go in a damp garage or shed?**

The listing advises that if the unit is used in a damp or humid environment, the MDF shelving decks should be treated with a good quality wood varnish or sealant.

**What does the guarantee cover?**

The listing states a 5 year guarantee and says the shelving is manufactured to European ISO 9001 standard. It does not set out what is excluded.
