COP v3.0:installation; product-selection

14.2 Product Selection 

The profile must be suitable for the strength requirements of the building, and appropriate for the minimum pitch, and the material selected must be suitable for the environment and be compatible with adjacent building materials. See 4 Durability.

Aluminium requires special installation details to achieve durability. See  14.19 Fixing Aluminium Sheeting for more details.

14.2.1 Measuring 

Measuring should take place once sufficient structure is in place to enable accurate calculation of lengths required. It is beneficial to make more than one measurement of any run to identify discrepancies and avoid errors.

14.2.2 Ordering 

Cladding materials should be ordered with enough time to allow for manufacture and transport. Profile, thickness, colour, grade, and any requirements for labelling of bundles should all be clearly identified

14.2.3 Transportation 

Load safety and protection is primarily the driver’s responsibility.

Short sheets should be packed on top of longer ones, which should have end and edge protection to avoid cut-end damage to the sheets below them. Dunnage should be evenly spaced in vertical alignment. Bundles must be placed and secured to protect against damage from other materials.

On longer distances, extra protection or packaging may be required to protect the material from fretting during transport.

For longer lengths, when a long boom is required for off-loading, a suitable boom should accompany the load unless otherwise arranged.
