Firstly, please kindly check the below two pics.
I believe some of you have the experience of buying clean room sandwich panel and faced the quality problems as the above pics. Except the wrong handling when you unload the panels, another main problem is the bad glue adhesiveness between core materials and the skin steel sheet.
We have not received this kind of complain from our customers for our clean room sandwich panels. All our production strictly follows the ISO quality management system and see the below video and pic you will know we have the test and approve inside our factory.
