What is the flight deck of a carrier covered with or made of besides steel, is it cement, asphalt etc... ? I have looked everywhere for an answer and find nothing. Thanks in advance to whoever knows and wants to tell me.

Tpye Flight Deck Coating into yhour search engine. When it come up scroll down until you come to Non-skid coating. This will tell you about flight dec coating.

I think it has some kind of rubber materal on top but it is like the wheels of scooters
