Description of Prepainted Aluminum Zinc Rolled Coil for Construction roof
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 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: I'm a big fan of stainless steel and sterling silver, but not of the humidity of the country I'm in. Therefore I sweat more. Gross, I know. I'm buying a necklace chain for my ring.So does sweat contribute to tarnishing of silver and steel? The real kind?
- steel shouldn't really tarnish, it rusts and moisture increases that. Silver tarnishes when exposed to air and sulfur. Moisture increases the process a bit, but it happens anyway. Sweat is not gross, it's a necessary function of your body, otherwise you would die. A lot of sports people wear jewelry and they sweat a lot. If you wear the jewelry all the time, that will prevent the tarnish a bit. If you take it off, clean it (water and dish washing liquid), dry it and put it in a zip lock back to keep it away from air and moisture. In the end, cleaning the jewelry is quick and easy so don't worry about it.
- Q: How are steel coils used in the production of steel fasteners?
- Steel coils are used in the production of steel fasteners by being processed into flat strips or wires, which are then cut, shaped, and threaded to create various types of fasteners such as screws, bolts, and nuts. The coils provide a continuous supply of steel material that is easily manipulable and can be efficiently transformed into the desired shape and size for fastener production.
- Q: All the appliances in my kitchen are stainless steel, and I hate how they look becuase every time I wash them they are full of streaks. Is there a good cleaner made for stainless steel that won't leave streaks?
- Stainless Steel Appliance Cleaning Stainless steel kitchen appliances look best when they're clean and shiny. To clean tough stains and cooking grease, and give them a dazzling shine, try the same detergent you would use when washing the dishes. One formulated to cut grease works especially well.This also works well for general kitchen cleaning.Waterless hand soap also works great as a polish, simply rub on, and polish - no rinsing.=)
- Q: I got my dog those nice looking stainless steel water and food bowls (looks great next to my kitchen appliances...haha). The thing is my dog will drink from the toilet or a plastic bowl but not out of his bowl...I was wondering if those stainless steel bowls change the taste of food and water?
- Well, I know the water at this restaurants where they use metal pitchers taste a bit off to me. There's nothing wrong with the water, but I think the metal pitcher throws off the flavor. Could be the same with the metal bowl and the dog. Plastic is only a problem at hiding bacteria if it gets scratched up badly (which isn't as likely to happen with water as long as the dog doesn't chew it. You can also put the plastic crock bowls on the top shelf of a dishwasher for cleaning as the heat kills most germs.
- Q: What is the weight of a steel coil?
- The weight of a steel coil can vary depending on its size and thickness. On average, a steel coil can weigh anywhere from a few hundred kilograms to several tonnes.
- Q: What exactly is surgical stainless steel made of (metals)? Does it contain nickel? If so, what % does it usually contain? I am deciding between surgical stainless steel piercings or titanium. Both same price and looks. I want to know which one is more hypo-allergenic and generally nickel free.
- surgical stainless steel is an austenitic steel containing 18-20% chromium and 8-10% nickel. and some proportion of molybdenum. The word 'surgical' refers to the fact that these types of steel are well-suited for making surgical instruments: they are easy to clean and sterilize, strong, and corrosion-resistant. The nickel/chrome/molybdenum alloys are also used for orthopaedic implants as aids in bone repair, and as a structural part of artificial heart valves and other implants. However, immune system reaction to nickel is a potential complication. In some cases today titanium is used instead in procedures that require a metal implant which will be permanent. Titanium is a reactive metal, the surface of which quickly oxidizes on exposure to air, creating a microstructured stable oxide surface. This provides a surface into which bone can grow and adhere in orthopaedic implants but which is incorrodible after implant. Thus steel may be used for temporary implants and the more expensive titanium for permanent ones

- Q: My mother is in a weilding class, and today she accidentally welded Galvanized Steel. She doesn't feel good and she wants to know what the symptoms are for Galvanized Poisoning from breathing in the Fumes. Please help, I am worried for her.
- i have a dog with a galvanized chain on her neck ''for looks'' can she get even the slightest harmful effect from it being on her 24/7?
- Q: How are steel coils inspected for surface defects using non-destructive testing methods?
- To ensure the quality and integrity of steel coils, non-destructive testing (NDT) methods are employed to inspect them for surface defects. Several common NDT methods are utilized in this process. Visual inspection is one of the most widely used methods, where trained inspectors visually examine the steel coils for visible defects like scratches, cracks, pits, or corrosion. Although this method is simple and cost-effective, it can only detect surface-level defects. Magnetic particle testing (MT) is another commonly used NDT method. It utilizes magnetism to identify surface and near-surface defects in ferromagnetic materials like steel. By applying a magnetic field and iron particles to the steel coil, any defects such as cracks or discontinuities become visible as the iron particles concentrate around them. Liquid penetrant testing (PT) is a different NDT method used for inspecting steel coils. It involves applying a liquid penetrant to the coil's surface, which is drawn into surface defects through capillary action. After removing excess penetrant and applying a developer, the defects become visible as the developer draws out the penetrant. Ultrasonic testing (UT) is widely used to detect both surface and subsurface defects in steel coils. It transmits high-frequency sound waves into the coil and analyzes the reflected waves to identify abnormalities. This method can detect defects like cracks, inclusions, and voids that may not be visible to the naked eye. Additionally, eddy current testing (ECT) is another NDT method for inspecting steel coils. It utilizes electromagnetic induction to detect surface and near-surface defects. By placing a coil carrying an alternating current near the surface of the coil being inspected, any changes in the coil's electrical conductivity caused by surface defects are detected and analyzed to identify and evaluate their severity. In summary, various non-destructive testing methods such as visual inspection, magnetic particle testing, liquid penetrant testing, ultrasonic testing, and eddy current testing are utilized to inspect steel coils for surface defects. These methods ensure the quality and integrity of the steel coils before they are used in various applications.
- Q: How are steel coils used in the manufacturing of pressure vessels?
- Steel coils are used in the manufacturing of pressure vessels as they are processed into flat sheets and then formed into the desired shape. These coils provide strength and durability to the pressure vessel, ensuring it can withstand high pressures and temperatures.
