Zincalume is a metallic-coated steel product and does not age like traditional materials. Its appearance may change over time due to weathering and exposure to elements, but it does not develop a patina or rust like zinc or other metals. The best way to maintain the appearance of Zincalume is to regularly clean it and apply appropriate coatings if needed.
zinc, originally However these days roofing is covered with a material called zincalume and the Kitchen and laundry sink is more likely to be made of stainless steel which is a mixture of nickel and iron.
Corrugated iron is the material used for roofing it is either Zinc coated or Zincalume coated the later is the modern version. Stainless steel is an alloy of steel and mainly nickel and far les likely to corrode then corrugated iron.
Neutral cure silicone sealant are used in places where there is metal present. like galvanised iron , zincalume, aluminum flashing's, etc where acids can be harmful to the materials that hold the seal. however these silicone's are suitable for most sealing applications in any case.
It is not recommended to clean a new galvanized metal roof with acetone as it can damage the coating. Instead, use a mild detergent and water solution to clean the roof surface. If there are stubborn stains, consult a professional for appropriate cleaning methods.
Using dissimilar metals together in damp situations will lead to electrolysis causing the repaired area to break down again. it would be wise to use a similar metal if you intend to use a sheet of metal. I suggest that you also get some rust converter to paint over the rusted area to arrest the rust. If you use galvanized iron to cover the hole make sure that the pool material is galvanized iron and not zincalume otherwise toy will end up wit the same problem.
I know A guy that put one into the ground all the way. It was a powder coat zincalume above ground pool, What he did was. # Dug a hole big enough to set the pool up in. he had a big pool. # he set it up to have the pool sticking 6 inches out of the ground # set up the pool according to the instructions. # His land had a slight slope so the pool stuck out of the ground a little more on one side than the other. # filled it up with water # then back filed around the outside of the pool with a 10/1 sand cement mix. # Et Voila, 20 years later he had to replace the liner. and everything was still ion great condition.
Galvanizing metal with zinc helps to protect it from rust and corrosion by creating a barrier between the metal and the surrounding environment. This process can increase the lifespan of the metal and reduce maintenance costs. Additionally, zinc is a sacrificial anode, which means it will corrode before the underlying metal, further extending its protection.
Corrugated iron is the parent material - usually with the traditional form of curved corrugations - but probably today comes in a number of variations on the size of these. Traditionally corrugated iron was zinc coated - known as galvanised iron. The zinc acts as a protective coating as it reacts chemically with the parent iron (which gives the strength) when this gets damaged or scratched or begins to deteriorate. Zincalum is a more modern invention and is an alloy made up of zinc and aluminum and behaves in much the same way as a zinc coating to protect the parent iron but because the zinc is in a body containing aluminum, it does not erode away at the same rate as pure zinc. Therefore the corrugated iron coated in zincalum will last much longer - maybe five times longer I believe. So they both do the basic roofing job but the expectation for life of the product so far as corrosion resistance is greatly improved.
Apparently you can I spoke to some one who did this as he was not interested in the hassle of having to remove an in ground pool later on when he got sick of it. The method he used was quite simple. He used a 5' deep above ground pool with powder coat zincalume surround. I forgot the dimensions of the pool but it was pretty big one. # Dig a hole to the depth required he had a fall in the land so he left the top rail of the pool about 4" / 100mm above the ground on the up hill side and ended up about a 1' / 300mm above the ground on the down hill side # make sure the hole floor is level and then cover it in about 4" / 100mm of washed river sand. # Build the pool inside the hole. # install necessary Plumbing. # Fill the pool. # After the pool is full of water back fill the gap between the pool and the ground with a 10 to 1 mix of sand cement. He told that this lasted him 20 years at which time the liner needed replacing when he took the old liner out he found that the rest of the pool was still in top condition.

Lead flashing was commonly used on chimneys, around other roof penetrations such as vent pipes, and roof junctions, such as valleys. It is still used for this, but is less common because of its cost, and the availability of alternatives. Modern alternatives: pvc, butyl rubber etc. are often less durable. It is used in sheets to create rain resistant junctions because it is soft and malleable and weather durable. The lead sheets are tapped with a rounded hammer around moulding shapes to conform to the shapes of the building they will be flashing. Because of the malleability of lead, these sheets can be shaped closely to awkward shapes, such as the junction of a sloping roof and a chimney, without the need for the sheet to be cut. Cuts in the sheet would create a potential leak site. Copper is also used for this purpose as it is also durable and malleable. It is usually more expensive than lead. Lead and copper should not be used in an area of roof where water is being collected for drinking water. Lead or copper should not be used where run-off water will flow onto Zincalume coated steel, as this will increase the rate of corrosion. This may also void a manufacturer's guarantee on the product.
