I bought one of their 9 x 6 x 2.7 sheds back in 2005 and 16 years later still very happy with it. Do read the floor installation instruction. It states to not concrete right up to the sheet. I bought 5 of 6m 75x35 and welded them upright around the bottom between the backside of the legs and the sheet to create a 30mm gap once the sheets were fitted and this gives you the edge to work from when screeding the concrete. You can literally hose the shed out straight over this edge. Absolutely no rust or corrosion on the sheets after 16 year. Fit the sheet lower so nothing blows in under the wall sheeting.
