Which is better, a stainless steel floating disc or an aluminum floating disc?

For floating roof storage tanks used for storing gasoline and diesel, from the perspective of safe production, which is better – a stainless steel floating roof or an aluminum floating roof?
Aluminum floating discs are good; they don’t produce sparks, I guess.
Stainless steel floating trays are good, but they are relatively expensive. For aluminum floating trays, the impact of fires needs to be taken into account, and more fire protection measures are required
Stainless steel has advantages such as high strength, strong corrosion resistance, a long service life, but it is also expensive. It mainly depends on the medium; the material of the floating disk is chosen based on the medium and its properties, in order to avoid unnecessary expenses. For example, if the floating disk can last for 25 years, will your tank be able to last that long?
I agree with what was said on floor 4; for finished gasoline and diesel, since their sulfur content is low, aluminum floating trays can also be used. Of course, stainless steel is still better if conditions permit.
Ignoring price factors, stainless steel is of course the better choice! ! However, the price doesn’t differ much; I recommend stainless steel! ! !
Stainless steel is great, but it’s also expensive
It can’t be generalized; it depends on the diameter of the storage tank. When the diameter is greater than 40 meters, aluminum floating trays cannot be used

There are no specification requirements for 40 meters; only structures over 48 meters cannot use prefabricated internal floating disks.
The material of the inner floating disk is primarily determined by referring to the storage material of the tank; the largest inner floating disks produced by our company are made of stainless steel and have a diameter of 60 meters. The largest for aluminum alloy is 46 meters.
