What are the quality problems you have encountered for sandwich panel ?

Updated: Nov 25, 2020

Firstly, please kindly check the below two pics.


I believe some of you have the experience of buying sandwich panel and faced the quality problems as the above pics. Except the wrong handling when you unload the insulated panels, another main problem is the bad glue adhesiveness between core insulation materials and the metal sheet skin.

We have not received this kind of complain from our customers for our insulted sandwich panels. All our production strictly follows the ISO quality management system, you can see the below video and pic then you will know we have the test and approval inside our factory.
