ALUMINIUM LADDER INSIDE WATER TANK - please help
(OP)
In a Under Ground Water Tank, to go inside the tank generally we provide Cast Iron Rungs. Instead of C.I.Rungs, can we use Aluminium ladder??? What are the advntages & disadvantage of Aluminium ladder inside the water tank. Please help..

Is this tank steel, and if so is it coated? I would consult with the ladder manufacturer on this one. Given that Aluminum is more anodic than steel, the aluminum runs a good risk of corroding. There are several other factors to consider as well, like pH of the water, what other materials are present in the water (maybe a sacrificial anode?). Also don't forget the little things such as the bolts...steel in contact with aluminum under water.
Given the different variables that could be encountered, it would be well worth it to play it safe and use like materials. Otherwise, I would consult a qualified Corrosion or Metallurgical Engineer.

However, all commercial aluminum alloys will corrode in water, especially if it contains chlorine or chloride, and corrosion in contact with steel or concrete has already been mentioned.
As a metallurgist in the aluminum finishing business, I will say that a powder coat of PE or similar over properly sealed hard anodized aluminum should last for many years. However, I would agree with the mjflorio that a fiberglass ladder is probably the most cost-effective, corrosion-resistant solution.
