Description of Prepainted Galvalume 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 Prepainted Galvalume Rolled 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.
Applications of Prepainted Galvalume Rolled Coil
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

- Q:How are steel coils used in the production of shipbuilding materials?
- Steel coils are used in the production of shipbuilding materials as they are typically cut and shaped into plates, sheets, or beams that are then used to construct various components of a ship's structure such as the hull, decks, and bulkheads. The coils provide a reliable and durable base material that can withstand the harsh marine environment and ensure the structural integrity and strength of the ship.
- Q:I personally don't believe the story of 8 guys who flew small planes can navigate passenger jets into buildings hundreds of miles away with that precision. It just doesn't make sense.I am wondering what the story surrounding the molten steel was, how could molten steel have been produced when fuel from the planes wasn't hot enough (it melts at 2850 degrees)?
- that's just it: there wasn't very much molten steel for the very reason you point out. Jet fuel burns at 800° to 1500°F. This is not hot enough to melt structural steel. However, engineers say that for the World Trade Center towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength. Steel will lose about half its strength at 1,200 degrees F. The steel will also become distorted when heat is not a uniform temperature. after the collapse, a LOT of folks took a look at the remains. the result was the conclusion that the fire caused the central core of the building to weaken. When the floors collapsed one on top of the other, the weight was too much for the weaked core to bear, causing the result we are all familiar with. hope this helps
- Q:Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?
- 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:steel can be used to do?
- Stainless steel can be used to (1) industrial use stainless steel (2) building decoration use stainless steel;(3) medical equipment (4) life with stainless steel tableware and the Jawaysteel is a great Chinese company, offer various kinds of stainless steel Maybe you can to their advice
- Q:I mean about if I had a piece of metal, how can i decide that's iron or steel?Sorry for bad English.
- Iron is a chemical element with the symbol Fe, that has no engineering application as it is very soft. You are not likely to come across a piece of metal of pure Iron. Steel is an alloy of Iron that is widely used with different types for various application. The type depends on the alloying elements. An old and rough way of identifying them is to use a chart, that shows the spark pattern when they are subjected to grinding.
- Q:What is the average lifespan of a steel coil storage rack?
- The average lifespan of a steel coil storage rack can vary depending on various factors such as the quality of the rack, the frequency and intensity of use, and proper maintenance. However, a well-maintained and durable steel coil storage rack can typically last for several decades.
- Q:I am getting a barn soon and I was debating between wood, and steel. I think steel would look nicer [painted of course] and I was wondering which is cheaper. Any extra info would be great. Thanks x
- Steel barns are much cheaper, but do require more insulation (they get extremely hot in summer and extremely cold in winter w/o insulation), and they have little to no maintinence. in my opinion though, a better-built wood barn is by far the better choice in the long run. They are much more sturdy, more visually appealing (to me), and if kept up well, will last much longer than a steel barn will. I also like that with a wood barn, during rain/hail/etc.etc. you don't have a deafening clatter that is unavoidable with steel barns.
- Q:What are the common coil loading and unloading techniques?
- The common coil loading and unloading techniques include using cranes or forklifts to lift and move the coils onto trucks or storage racks. Another technique is using coil transfer cars or coil handling equipment to transport the coils within a facility. Additionally, some facilities utilize coil upenders or turnstiles to rotate the coils for easier loading and unloading.
- Q:How are steel coils used in the manufacturing of automotive body panels?
- Steel coils are used in the manufacturing of automotive body panels by being processed and shaped into the desired form through techniques like stamping or roll forming. These coils provide the raw material for creating strong and durable body panels, ensuring the vehicle's structural integrity and safety.
- Q:I also heard Stainless holds up better againts rust, blue steel needs more care.
- Blue Steel is definitely stronger than stainless. Le Tigre and Ferrari are too. However, nothing compares to the strength of 'Blue Steel' to a non-ambi-turner.
