For the PU panel installation:
We use cam-lock systems to connect the panels in the PU panel. Before you begin connecting, double-check that the locking devices are in the correct position. To do so, turn the locking devices counter-clockwise with force, using a wrench, until they stop moving.
Connect the PU panels by putting them together and turning the wrench clockwise. This will engage the male lock rather than the female lock.

Keep rotating the wrench until it doesn’t move any farther. Then it’s finished.
Turn the wrench counter-clockwise to the end if you have any difficulty operating the cam locks, for example, the male lock is somewhat shorter (with force until it stops moving any further). The locking device will return to its original position as a result of this action.PU panel width

As you can see, the installation of PU panels for cold room is simple. For not so large size of cold room, we recommend the PU panels as the cold room building material.
Different prices for different customizations. Any size of cold room and requirements is acceptable.
