(OP)
Hi,

I'm looking for a metal grill, that closes it's flaps when I step on a button, and opens the flaps when I release my foot. May I know where can I find such a design?

RE: A metal grill that open and close via force

Do a search on dampers, they come in all forms and strength of design.

RE: A metal grill that open and close via force

Use a motorized damper connected to a push-button switch.
