75mm Cold storage room PIR/PUR wall insulated sandwich panels


1.PU foam wall panels type:

 

 Tongue and groove joint wall panels:

pu insulation panel manufacturer 

Panel effective width: 920/1000/1120 mm

Thickness: 75/ 100/ 150/ 200/ 250 mm

This panel type ensure the joint tightness,and the insulation performance of cold room.

 

2.Sandwich panel wall applications:

cold room pu panel suppliers 

This PU wall sandwich panel is mainly used in refrigeration or refrigeration equipment in food and other industries, such as refrigerators, freezers, cold storage, refrigerated trucks, etc. Polyurethane rigid foam is the most ideal thermal insulation material for refrigeration and refrigeration equipment.

 

3.Wall panels material description:

6.Insulated wall 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;

03 PU sandwich panels packing 

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;

04 metal sandwich panels stacking 

 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 its for domestic market,it will be transported by truck.If its 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.
