Date:Jun 26, 2019
This Wednesday, a colleague and a technician from the factory will go to guangzhou to participate in the UL certification test.I went to help the workers of UL to instruct them how to build the wall and install our wooden fire door. This time, we will inspect the wooden fire door UL90 minutes.It takes a day to build the walls, but the walls have to be dry, it takes 3-4 days, it takes a day to burn the doors, so it takes a week.The verification of wood fire doors is our company's future development direction, because our wood fire doors through the verification is not many, so the orders received a lot of restrictions.
Hope that everything in smooth water.
