Structure of Aluminum Zinc Rolled Coil

 Prepainted Aluminum Zinc Rolled Coil for Roof Construction

Description of Aluminum Zinc Rolled Coil
Aluminum zinc coils 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 Aluminum Zinc Rolled Coil for Construction Roof

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.

Q:carbon steel strength?
There's no way to tell from the information you posted. Given it's for a machete I would guess it would be a fairly high carbon steel. Rust resistance will be relatively poor. It will last for years though as long as you clean and dry it after use.
Q:Explain how you could make plastic sink and steel float?
you can use the steel to make a hollow box, or a ship. There are thousands of steel ships floating in the oceans. plastic, specific gravity ranges from 0.6 to 2, so the higher density ones will sink. Here are some that will sink: Nylon (Polyamide) 1.15 g/mL Plexiglass (Polymethylmethacrylate or PMMA) 1.19 g/mL Lexan (Polycarbonate) 1.2 g/mL PVC (Polyvinyl chloride) 1.16-1.38 g/mL PETE (Polyethylene terephthalate) 1.38-1.39 g/mL .
Q:what can i do to polish steel or iron?
If the steel knife is dark and not mirror-shiny, then it is probably carbon steel and not stainless steel. If they are carbon steel, then you cannot polish it to a mirror finish - sorry. If there's any rust on them, you can use a very-fine grit sandpaper to remove. Do not put carbon steel knives in the dishwasher, and dry them thoroughly after hand-washing. For long-term storage (meaning you don't plan to use the knife within the next few weeks), wipe the blade a bit with some mineral oil, then store the blade portion of the knife in a plastic bag.
Q:911 conspiacy theorists. Can fire melt steel?
They can't melt that fast At that temperature, the fire caused by the jet's fuel didn't hot enough to melt the concrete steel. As you see in the video the flame took only 20 minutes. The heat is not fast enough to penetrate all fragment of the concrete steel from top to the foundation, steel is not a good heat conductor like the iron. The explosion only took 5 stories, even all flame in all stories will take 4 hours to melt the core - in this case the core is the worst quality alloy which I don't think is used by WTC. The speed of the falling of WTC building was way too fast. It only took about 9.5 seconds. As an illustration, we throw an object - no matter the weight from the top of WTC, let's count how long it takes from the top to the ground as easy as senior high physics. We took the height of as h = 526.3 m, the gravity 9.8 m/s^2 then apply them to the Newton's equations, h = 1/2*g*t^2 then t = sqrt(2*h/g) = sqrt(526.3/9.8) = 7.32 seconds. The difference is just 2.2 seconds. The resistance of the concrete and solid materials should give at least 200% of the fall duration. WTC's 9.5 secs to fall is even faster a ball sliding on its wall from top the ground. I don't know what happened there. But my Basic Physics lecturer at first grade in my college -who concentrates in Materials- said that it is very odd that the flame burning 5 stories (at most 2% of 110 stories WTC) took only 20 minutes to melt the core of 30% after explosion top stories' core. A friend of mine, got summa cumlaude Bsc in civil engineering - concentrated in structure, said that the pan cake fall has never occured before due to fire causes. If the heat is hot enough to melt the core then the building should bend forward at a broad angle because the strain caused by the heat is not uniformly distributed along the building's core - remember steel is not a good heat conductor. I'm not speculatiing, but 9/11 is an odd tragedy
Q:Heat transfer through steel?
I cant see how you could solve that when you don’t know the type of steel ( specifically). There are many in the range you have stated. Also volume, respecting the length of the tube and coverage of the exterior heat. Logic tells us however 3 seconds is not very long so next you would need to know are the post factor. if the flame was from say a cutting torch and the tube was 20' in length in an ambient exterior temp of 32deg. We could us known a test and determine the rate at which the heat was spread out through the steel. You can also measure pressure in the tube You can find easily resource material on the amount of energy it takes to raise temp by a factor of one. By testing the pressure of a sealed tube of a given length you can apply the solution in scale to your problem. You can also try sticking your finger in it.
Q:Copper pots....tin or stainless steel lined?
Stainless steel is durable and does not disolve and make things taste funny. Stainless steel is not a good conductor of heat, so it has hot and cold spots. Copper is very good conductor. They noe bond copper to stainless steel to get the best features of each. Some pots just have a very thin copper plating to fool you. A good pot will be heavier, It is really hard to tell from looking.if it is plating or a bonded layer of copper. the thicker the better
Q:Steel vs. Dark Pokemon?
Dark Steel Pokemon
Q:Red steel games don't look alike...?
Red Steel 2 isn't really a sequel to Red Steel 1 in a normal sense. The reason the new one is named Red Steel 2 is because of the Sword + Gun combat, which was also in the first game (even though the sword part wasn't good in the first one). Other than that, I'm guessing Ubisoft just wanted to take a different, less realistic approach with it.
Q:Stainless steel vs carbon steel for swords?
Stainless steel is not as strong as tempered carbon steel, especially at that length. But damascus steel only looks different. In terms of metal quality, pure modern steel is better in flexibility. Cheness uses 9260 spring steel alloy from high carbon steel. Stainless is rated 440. You can look them up on wikipedia to learn about qualities. Edge retention and hardness is better at the 1095 level or the T10 tungsten steel or tool steel level. As for who to trust, sbg-sword-store.sword-buyers-guid... + free shipping
