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:physics compression:Steel rod?
You need to calculate the stress on the rod and compare this with the mechanical properties of the steel. It would help if you were given more info. You will need to know something about the steel such as the yeild stress and E, the modulus of elasticity. The value of E is about the same for a wide range of steels. So long as the applied stress is below the yield stress, the strain is all elastic and is calculated from E. The real answer is that you can not answer this question since you do not know what the temperature is. Given the applied load, the change in length will be much different at room temperature than at 1500C.
Q:Shaft stiffness in steel irons???
If i understand you correctly, i think you misunderstand shafts. Steel shafts vs. graphite shafts these days is more of a competition of weights, not flexibility. Both steel and Graphite have different flex profiles available from Ladies (L) to super stiff (X). Graphite may feel a little more whippy than steel because of the lighter weight. Shafts will vary by company as well. Stiff from True temper may not be as stiff as one from Aldila, or vice verse. You can also make a shaft play stiffer or more flexible by where you cut the length. This is called tipping. Take more from the bottom and it will be stiffer, more from the grip end and it will play more flexible.
Q:Aluminum vs Steel motorcycle gas tank?
Steel is most common. Aluminum is lighter but it's harder to form, so more expensive. Plus it dents more easily. And you can't use a magnetic tank bag. I've seen stainless steel tanks but they were usually specially made.
Q:What happens to the solution of copper (II) sulfate when steel wool is added?
Steel is an iron alloy, and iron is more reactive than copper, so what you'd see is the blue colour of the solution becoming lighter, and a black precipitate appearing on the steel wool.
Q:Quick ... Does fire burn steel?
Easy. okorder.com/
Q:How to get katana in Red Steel?
Sure.
Q:Does mild steel rust?
Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
Q:Can rubbing alcohol help clean stainless steel?
no if it was stainless it would have not rusted, we use lemon juice and a brillo pad
Q:How does water cooling affect the hardness of steel?
When steel is slowly cooled, lots of carbon diffusion takes place because it is not very soluble in steel at room temperature. The carbon is in solution at high temperatures, and is rejected out of the lattice as it cools. And when this happens, the microstructure will consist of ferrite and pearlite, and the lattice structure will be base centered cubic (bcc). If it is cooled fast enough, then the carbon gets trapped in the interstitial sites of the lattice and distorts it to a body centered tetragonal (same as bcc, but elongated in one direction) This elongation strains the lattice and makes it harder. Also, when cooled fast enough the atoms do not have time to diffuse like they normally would and they shear into place. This forms the hard phase of martensite that is desired of heat treated steel. But then it must be tempered back some because it is too brittle.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
And the length has a lot to do with the thickness. So the total length of the volume is not good.
