this is interesting.. What is meant by steel deck(ing)

diamond pattern--like seen on trucks?

Open waffle like seen on bridges?

1/2 (10 cm) thick sheets, seen on NYC roads?

corragaged sheets used as substructure for poured concrete (used constructing elevated highways?--and in hi rise buildings?)

textured steel uses as decking for things like ships/aircraft carriers?

steel commopents used for exterior home buildings? (terraces, patios, etc. --i have steel storm windows and doors)

Are there other types of steel deck? the two previously mentioned, (etaoin & ...) made me realize i wasn't thinking of what they defined, but of the large (2 meters by 4 meters or so) steel plates that are often used in NYC to temporarilly cover openings in the street-- and then i thought of the others types..
(and NYC subway steps have these diamond embosed type steel plates to protect the concrete from wear.. not quite deck, but...)
i never realized i knew so many types...and that all of them, just are 'steel deck'. but i suspect some have other names. and that there are other types i haven't thought about.




my other obsession
