Steel Deck topping
Steel Deck topping
(OP)
Hi,
If you just want to use steel deck as raining shed instead of thin metal or plastic roofing. Is it possible to just use some kind of say insulated panel over the steel deck or even plastic roofing material over it.. or do you have to top it with concrete? But this would be so heavy.. what other ways to top the steel deck.. which do you use?
Also what are the advantage of using steel deck as material to shed rain rather than thin metal roof? Won't it be overkill? Perhaps you use steel deck to avoid robbers from axing his way into the house via the thin metal roof or jogging above? what else why choose steel deck?
And what are the common gauges of it that is used for just rain roofing.. for walking, and for parking?

But how do you waterproof it from rain? unless you mean the steel deck is itself the waterproof surface by applying waterproof paint to the surface? Or do you have to cover it with other membrane and what are these? Thanks.

What would happen if you just apply epoxy primer to prevent the steel deck from getting rusted.. and not applying anything else (because it would add to the cost a lot)?
And what is the problem you guys encountered with Long span roof. How many percentage is this used in the US versus steel deck?

What do you mean by long span roof vs steel deck?
RE: Steel Deck topping
The following is called Long span roofing in Asia.. don't you use it elsewhere? We use it in 99% of building in our place.
If you don't use it in your country (no?). What do you use as roof besides steel deck?
RE: Steel Deck topping
Not sure what your goal is, but look up the SDI (steel deck institute) or vulcraft if you want to see structural decking that is used for roofs. IT is NOT a waterproof decking, it is a structural deck. For roofs, they often top it with rigid insulation and a TPO membrane.

My goal is just to have a roof that can shed rain. So I guess the standing seam metal decking will do. I now understand why majority in my place use it. Because a steel deck is much more expensive.. with bigger beams and rafters.. and the steel deck itself more expensive and the waterproof membrane even more expensive.. and the price would become like 7 times that of standing seam metal decking. Thank you.

i've seen a few steel roof decks that have roofing boards attached and waterproofed, then insulation and ballast.

In your estimation. How much heavier is a steel deck versus corrugated lightweight steel roofing? In our place.. most steel deck are poured with concrete cover and only used if you will use it as parking and not as ordinary roof. So in Australia.. what reason people use steel deck vs the lighter corrugated steel roofing? And is membrane really very expensive?
Also for moment frames without any shear wall or brace framed.. what would be the benefit of roof diaphragm and diaphragm action of the steel deck?
