FFU blind plate is also called FFU aluminum alloy ceiling keel, ceiling blind plate, double-sided colored steel plaster blind plate or double-sided colored steel paper honeycomb blind plate. Most used in the rear flange of the liquid or gas valve for blocking. Especially when the valve leaks inside, the blind plate can prevent the liquid/gas from leaking to the place to be treated.
