Packaging varies according to the types of sandwich and trapezoidal panels delivered by land. The packages are separated by EPS (expanded polystyrene) spacers/wedges. These wedges ensure there is proper spacing between the packages so they can be held and moved with a forklift, crane or other lifting devices and they also keep the panels from knocking against each other. 

Under Ex Works terms the buyer is responsible for equipment and workmanship to unload the packages. A forklift or crane is used to move the goods depending on their dimension and weight. 

It is important to protect the edges of sandwich panels and trapezoidal sheets when getting them up on the roof. When using a crane a flat-belt is recommended and, by no means a chain or a wire rope. When lifting the materials up onto a roof the edges must be well-protected. Special care should be taken not to place too much pressure on the sheets.  

If possible a device should be used in order to scatter the weight under the packages. 

When removing the sheets or panels from a pile they must be pulled sideways to detach them and held upright to avoid scratching the surface of the other panels below. 

When unloading the panels from the vehicle or when lifting them to the roof, they should not be held and carried by their edges or corners alone but must be held by different parts










Panels up to 6 mt long can be handled with a forklift or a crane. Care should be taken not to damage the panels lying below if a forklift is used to handle the packages and the panel edges should be protected if a lifting beam is used.

If the roof panels are up to 15 mt long and the wall panels up to 8 mt long they can be installed manually but if the panels are longer than that then a crane must be used to do the mounting. 

When taking the panels out of their packages one by one avoid dragging them on other panels in order to prevent scratching. When moving the panels they should be seized by their edges to avoid warping.

If the panels come with a protective film, it must be removed right after the installation. If the panels need to be stored for a long period then it is recommended to keep the protective film on for 2 weeks at most, otherwise it will adhere to the metal sheets due to the effect of sunlight and it will be impossible to remove. 



Panels are usually stored for a while at the building site. Storage should be carried out with the following precautions. 

Before or after installation, the sheets or panels should not be exposed to and affected by corrosive elements such as soil, lime, mortar, fertilizers, acids, salt or alkali. 

Avoid all activity on the panels that might lead to scratching. Panels or sheets should not be left in places where someone might walk on them.
