1/ The thickness of the cladding (planks of wood) is a major factor to take into account. On some of the cheap sheds the walls are only 6mm (1/4 inch) thick. That is less than the thickness of a pencil. To give an idea how strong (or should I say weak) that is then take a pencil and try to break it. You will find it breaks very easily. Combined with the very thin framing this can not be good in anything except the short term.
2/ Another thing to beware of it is how the thickness is measured. A great many companies display the sizes of their cladding and framing as NOMINAL sizes which is larger than the ACTUAL size. Nominal size is the size of the plank of timber before is taken into the factory and planed into shiplap or T&G. This can make the timber appear thicker than it really is.
3/ Our Diamond and Platinum Buildings are made using European Redwood deal, not the cheap white wood used on (putting it politely) the cheap sheds available. Redwood is more expensive than whitewood but tends to have tighter grain that the fast growing white wood and tends to have a waxy feel to the bare wood whereas whitewood is very dry and porous. Any knots present in redwood are normally more stable that white wood. Whitewood has lots of tiny finger size knots which can drop out easily.
On ALL our pages we display either the FINISHED size or both NOMINAL and FINISHED so there is no confusion as to the size of timber supplied. We use redwood deal on all our Diamond and Platinum sheds and the thickness of all the timber is quite substantial.
