Structure of Al-Zinc coated steel coil

  Al-Zinc coated steel coil For Construction roof

Description of Aluminum Zinc Rolled Coil
The detailed information for the Al-Zinc coated steel coil is as following and it is mainly using for roofing producing, making ceiling grid and all kinds of roll forming structure.
Thickness: 0.20mm to 1.20mm
Width: 914mm, 1000mm, 1200mm, 1219mm and 1250mm, or slit narrow strip according to customer request, can be slit from 20mm to 610mm.
Coil ID: 508mm
Coil weight: 3 tons to 6 tons
Thickness tolerance: +/- 0.02mm or according to customer request.



Main Feature of Al-Zinc coated steel coil

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:Is 30CrNiMo8 a kind of high alloy STEEL?
It is a high alloy steel. Look at all the elements in it's name for it's composition: 30% Chromium and Nickel 8% Molybdenum Sounds like a very tough stainless tool steel for cutting rock or something. Chromium and nickel arre the two elements they use to make stainless steel and molybdenum is used to make steel very hard and wear resistant
Q:Are scandium revolvers as durable as steel?
This Site Might Help You. RE: Are scandium revolvers as durable as steel? I want to hear from those who own a scandium revolver. I know that scandium makes for a much lighter gun than steel, but how do they hold up durability-wise? Is their lifespan shorter than a comparable steel revolver?
Q:Stainless Steel Used In Knifes?
There Stainless steel doesn't make the best knife blade. It doesn't sharpen as sharp or hold its edge as well. High carbon steel is better, but it rusts and discolors very easily so it's not as popular. A new thing (actually not new but popular these days) is to use a 'sandwich' of high carbon steel between two layers of stainless. So the actual edge is high carbon steel but the blade looks like stainless. I have some kitchen knives made this way (kind of expensive) and I love them. This same technique was used in Japanese katanas, swords used by samurai warriors.
Q:hard ionized vs stainless steel cookware?
A good quality stainless steel cookware set is a necessity- it is virtually indestructible and you can use the harshest of scrubbers to clean it. You will need a basic set that has a 8 and 12 fry pan/omelet pan, a large pot that holds a minimum of 4 quarts, and 2 sauce pots at 1 quart and 2 1/2 quart sizes. I have several pieces of hard anodized cookware too- they do a wonderful job but food will still stick. A must is at least one Green Pan- preferably a 10-12 fry pan. They are truly non-stick, clean up is a breeze and making foods like fried eggs is infinitely easier when they slide out of the pan without breaking. They do not have the same issues that plague teflon pans- scrapes and shedding that you are ultimately consuming. You can easily find them online and at your area Target store.
Q:Does steel make its own static electricity?
No. Steel does not build up static electricity by itself. Also, magnetic fields are made by moving electricity, not static electicity. The steel conducts magnetism, so it changes the earth's magnetic field near itself by conducting the field through itself. The larger effect is a magnet near a piece of steel: the compass has a magnet, and when you place it near a ferromagnetic material, it attracts. Try putting a refridgerator magnet against the fridge - it sticks because it attracts.
Q:steel or aluminum horse trailer?
I bought a steel trailer. It was much heavier than the aluminum, as you said. But really, they are equivalents. As long as you have enough power to haul the trailer, you can use steel. We never had a rust problem with ours. In PA you do pay sales tax on horse trailers, stock trailers, etc. I forget about the plates, though. It's been a few years since we got our trailer. I would assume they would give you something to get the trailer home with though.
Q:Quality of a 440A steel blade?
Its the standard for most knives and its the easiest to sharpen, I have a couple 440 steel knives and they have never failed me, my oldest one is 11 years old and I have stabbed multiple people(in self defense, cut open backpacks, seat belts, fishing string, limes, thin rope, jeans, jackets, pockets, seats, popped tires, moved hot charcoal and other stuff, it just has to be sharpened every now and then. Although I really like carbon knives like KA-BAR's those are amazing and are the only fixed blade knife I would ever buy.
Q:Is Steel crystalline in its makeup?
Steel Crystalline Structure
Q:Which industries consume the most steel?
I'm guessing manufacturing
Q:Is 1045 steel pretty good for a knife blade?
