6.Insulated roof panel packing & loading:

☆ Packing:
→ Sandwich panels will be sealed with PVC film to protect the surface steel sheets from damage;
→ Using our PU sandwich panels packing machine,and packing with nylon to make panels in suitable quantity and bundles;

→ After finishing the packing,we will stack them in neat and dry place,also will put sleeper or foam as support,to avoid any water on the groud to break the panels.


☆ Loading:
→ The delivery time for Yumi steel sandwich panels is depending on seasons and thickness of panels;
→ Each delivery is depending on where to deliver,if it's for domestic market,it will be transported by truck.If it's for foreign market,panels will be loaded in containers and delivered;
→ Loading and carrying surfaces in trucks or containers must be clean and dry. No nails or other sharp objects are allowed to be appeared in truck or containers. If any accessories,which is considering as protruding objects,then they have to be properly secured (should be packed with wooden blocks or waste foam), to avoid damage to the panels.
