The majority of deliveries in the UK are offloaded by piggyback forklift. However with subsequent crane handling you should be careful to avoid damage to the edges of the sheets. Use rope slings (not chains) and over the width use spreaders to eliminate the possibility of damage. The corners of the sheets are particularly vulnerable during the transportation period.
Never Push, drag or slide a sheet from the stack. Always consciously remove the sheet by lifting from the stack. Similarly lift the sheet into position on a roof, do not push or drag over the purlins or other roof sheets.
If an on site lift facility is unavailable each sheet should be carefully removed by hand as described above. Once removed, they should be manoeuvred into position by two men, one at each end.
Particular care should be taken in windy conditions.
Never under any circumstances walk on any sheets either on the ground, in a stack or on the roof.
If several stacks are to be laid one on top of another, timber cross bearers should be placed at 500mm intervals up to a maximum height of 300mm.
Sheets and accessories should ideally be stored inside until the sheets are in position on the building. They could be subject to damage from site debris and accidental collision. Rainwater condensation and extreme weather conditions can also adversely effect the sheets (particularly coloured sheets) during this storage period.
If it is not possible to store the products inside a building, a suitable site should be selected. The ground should be firm, level and as close to the construction site as possible. The sheets must be stacked on the cross bearers thus raising them off the ground. A simple protective frame should be constructed and covered with a waterproof material. Air must be allowed to circulate all round the stack. The whole frame and stack should be tilted to
encourage rainwater to drain freely.
The sheets are supplied covered in shrink wrapping, it is strongly recommended that this wrapping is not removed until the sheets are required for fixing. Should any sheets remain unused at the end of the working day all the sheets must be re-covered.
Whether the product is stored inside or outside the stacks should be regularly inspected to ensure that moisture has not penetrated the coverings. Coloured sheets are particularly vulnerable at this stage.
