4. Panel advantages:


○ High adiabatic capability comes from the core of rigid PUR, and additional seals are installed in steel insulated panel manufacturing process.

○ High fire resistance to achieved through special panels and locking joints on both sides of roof sandwich panel.

○ Easy to install lock cone and conical cone on the surface of the internal joint.

○ Compatible system - panel uses different core materials to match other panels.

○ The ability to match panels of different thickness.

○ In forming metal sheets, durable corrosion resistant coatings can be obtained by using appropriate technology.

○ Due to the trapezoidal profile of the external sandwich insulated panels, the bearing capacity is high.

○ Good discharge of rainwater.


5. Packing & Stacking of PU roof panels:


1) Sandwich panels will be sealed with PVC film to protect the surface steel sheets from damage;

2) Using our PU sandwich panels packing machine,and packing with nylon to make panels in suitable quantity and bundles;

6. Transportation for insulation panels:


1) The delivery time for Yumi steel sandwich panels is depending on seasons and thickness of panels;

2) 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;

3) 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.


7. Unloading for sandwich panels:


• Before starting to unload PU sandwich panels, check the package condition status,and confirm they are in good status,then could arrage unloading;

• Packages of insulated panels should be unloaded with an overhead travelling crane or lift.Packages can be unloaded also with forklift;

• For unloading with picture introduction, please contact us to send you for reference.
