Price and rating as shown on Amazon when we collected them. Both change.

The Duramax TOP 8x6 is the second shed in this guide: a hot-dipped galvanized steel storage shed in anthracite, listed at £349.70 with 4.6 out of 5 from 52 ratings. At 78 kg it sits at the heavy end of the 8x6 and 8x4 metal sheds here, and it comes with a 25-year warranty.

Its own listing disagrees with itself about the measurements. The spec table gives 1.83D x 2.62W x 2.05H metres; the bullet gives external dimensions (L x W x H) of 261.6 x 183 x 204.5 cm. Those are the same two figures with the depth and width labels swapped — one entry calls the 1.83 m side the depth, the other calls the 2.62 m side the width. The declared floor area of 4.79 m2 only works one way: 2.616 x 1.83 comes to 4.79 m2, which is the outside footprint rather than the floor you actually stand on. And the chamber depth is listed as 173 cm, exactly the same number as the door height. Everything on this page comes from the Amazon listing, not from any test we carried out.

Questions people ask

How big is the Duramax TOP 8x6 shed?

The listing gives two sets of figures. The spec table says 1.83D x 2.62W x 2.05H metres; the bullet gives external dimensions of 261.6 x 183 x 204.5 cm (L x W x H). Those are the same measurements with the depth and width labels the other way round, so check which side you need before ordering.

Does the stated floor area match those figures?

Only if you measure the outside. 2.616 m x 1.83 m comes to 4.79 m2, which is the external footprint the listing quotes, so the usable floor inside will be smaller than 4.79 m2.

How much does the Duramax TOP shed weigh?

The listing gives 78 kg.

Does it need assembling?

Yes. The listing states assembly is required, and it also lists a 25-year warranty.

How much snow can the roof hold?

The listing says the reinforced metal roof structure can hold up to 20 lbs/sq ft of snow.

How thick is the steel?

The listing says the hot-dipped galvanized steel is "20 thicker" than conventional sheds, but never says whether that is 20 mm, 20 per cent or something else, so the claim cannot be checked from the page.
