  1. Fork Lift Handling: Most deliveries in the UK are off-loaded by truck-mounted moffett fork lifts. However, any subsequent crane handling should use rope slings (not chains) and over-width spreaders to avoid damaging the edges of the sheets, particularly the corners, which are especially vulnerable during transportation.

  2. Sheet Removal: Do not push, drag or slide a sheet from the stack. Instead, consciously remove the sheets by lifting them from the stack. Likewise, lift the sheet into position on a roof, avoiding pushing or dragging it over the purlins or other roof sheets.

  3. Manual Handling: If no on-site lifting facility is available, each sheet should be carefully removed by hand as described above. Once removed, they should be manoeuvred into position by two individuals at each end. Please exercise additional caution in windy conditions.


  1. Indoor Storage: Ideally, sheets and accessories should be stored inside a building to protect them from site debris, accidental collision, rainwater, condensation and extreme weather conditions. These elements can cause damage, particularly to coloured sheets, and may lead to efflorescence staining, bowing during installation or permanent distortion.

  2. Shrink Wrapping: The sheets may be supplied covered in shrink wrapping, which is designed to protect the sheets during transit. If delivered with wrapping, do not remove it until the sheets are required for fixing. Any unused sheets at the end of the working period must be re-covered.

  3. Outdoor Storage: If indoor storage is not possible, choose a suitable site that is firm, level and close to the construction work. Sheets should be stacked on cross bearers, raised off the ground. Construct a simple protective frame and cover it with waterproof material, allowing air to circulate around the stack. Ensure that the frame and stack are tilted for rainwater drainage.

  4. Foot Traffic: Keep foot traffic on sheets to a minimum, whether on the ground, stacked or fixed on the roof. Do not step on side lap corrugations.

  5. Stacking: Stacks without additional timber cross bearers should not exceed 1200mm, and cross bearers should be spaced no more than 1 metre apart. Different length sheets should ideally be stacked separately. If stacking with longer sheets, place them on top, ensuring their cross bearers line up vertically.

  6. Multiple Stacks: If stacking several stacks one on top of the other, place timber cross bearers at 500mm intervals up to a maximum height of 3000mm. Ensure that the ground is level and firm.

  7. Inspection: Regularly inspect the stacks to ensure moisture has not penetrated the coverings. Coloured sheets are particularly vulnerable at this stage.
