The second part is not mandatory but describes better options or alternatives. They are described by the words ‘should’, ‘recommend’, ‘preferred’ and ‘may’.

The reasoning used to formulate the above is printed in blue
-the ‘Why’.
The third part is informative, i.e. it is for information and reference.

1. Please ensure that materials should be kept dry before installation. Please also note that it should not be assumed that because the cladding/purlins will be eventually installed out in the weather, therefore protection is not required. Dry storage is required at all times. Poor storage could result in spoiling the surface appearance & severely reducing service life of the product.
