 Prepainted rolled Steel Coil for Construction Roofing

Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.

Main Feature of Prepainted Rolled steel Coil for Construction Roofing

1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will  form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside. 
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover. 
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials. 
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.

The carbon content of the knife is done during the smelting process.For instance a knife that has a high carbon content will keep an edge much longer than one with a lower content.

Q:Besides stainless steel....?
Silver, white gold and titanium are quite common.
Q:Disadvantages of stainless steel?
Stainless Steel has more advantages than disadvantages. But u asked for disadvantages so they r as follows i've given common disadvantages more can be found on Google. Disadvantages of Stainless Steel: Stainless steel tends to scratch and dent. Food, grease and fingerprints show very clearly on stainless steel, making frequent wiping and cleaning a necessity. High initial cost Difficult to fabricate, or in other words, it is not as malleable as other metals, say iron, and hence if not fabricated properly, results in costly re-work. Difficult to weld High cost of polishing etc. i.e. adding finishing touches for the market. there are advantages more than disadvantages. But u asked for disadvantages that's why i have given only disadvantages of stainless steel Hope what u want u got.
Q:Liquid stainless steel paint?
I am also considering buying Thomas Liquid Steel, but have not used it or seen it used before. I did call a store that sells this product and they said they saw the mfg demo the product at a trade show. The store rep told me that the results were absolutely amazing. I think I will buy the medium kit direct from the mfg for $129 and give it a test run first on something other than my kitchen appliances.
Q:will a stainless steel gun rust?
Stainless steel WILL rust, but it takes longer. Just think of Stainless as stain less - less, but still present. Clean it as you would any other blued firearm. Keep the same coating of protective oil or preservative lubrican on it as you would a blued gun, and it will look shiny pretty much forever. Stainless steel is not rustproof...it is merely MUCH more forgiving of a harsh world than blued steel. Stainless is not the same as hard chrome. Stainless is STILL steel...so you may have to brush it in places a lot to get the crud out, especially after those thousand-round marathon shooting sessions. But the results are pretty impressive, as you will soon see. Happy shooting!
