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: what happened to all the steel beams from the WTC buildings? did anyone do any forensic analysisof any of the steel?
- some of the steel was recycled into a warship. I am not sure at what you are trying to get at with the forensic analysis of the steel. There is no conspiracy involving the towers outside of planes crashing into them despite what a lunatic fringe want you to think.
- Q: What are the different types of steel coatings used on coils?
- There are several types of steel coatings used on coils, including galvanized coatings, zinc-nickel coatings, aluminum-zinc coatings, and organic coatings.
- Q: How are steel coils used in the production of bridges?
- Steel coils are used in the production of bridges as they are processed and shaped into various structural components like beams, plates, and girders. These coils are first uncoiled and then cut, rolled, and welded to create the required bridge sections. The high strength and durability of steel make it an ideal material for bridges, and the use of steel coils allows for efficient and precise manufacturing of these vital infrastructure elements.
- Q: Can steel coils be coated with anti-graffiti materials?
- Yes, steel coils can be coated with anti-graffiti materials. These materials create a protective layer that can prevent graffiti from adhering to the surface, making it easier to remove any unwanted markings.
- Q: How are steel coils used in the production of shipbuilding materials?
- Steel coils are used in shipbuilding materials as they provide a versatile and durable solution. They can be processed into various shapes and sizes, including plates, beams, and sections, which are essential components for constructing ships. The coils are often cut and shaped to fit specific design requirements, offering strength and structural integrity to the ship's framework. Additionally, the coils are utilized in the fabrication of various shipbuilding components, such as hulls, decks, bulkheads, and superstructures, ensuring the vessels' resilience and stability.
- Q: I am searching for an online article which discusses any aspect of the use of austenitic stainless steels. I was just wondering if anyone could help me find one. No sales articles. Thank you!

- Q: I'm trying to make a corset but I can't find any steel boning in my area. Any clue as to what materials I could buy to to make my own bones, or anything that would work similarly?I know there are places to buy it online, but the cost of shipping makes it barely seem worth it.
- Don't try it. For two main reasons: 1. Corset boning is not just strips of flat steel; it is made from coiled high tension spring steel with clever metal ends to prevent tearing any fabric that comes into contact. You could try strips of hard wood such as teak, ash, oak. The risk is that the st rips will break when they bend around your corseted figure. Then they'll be dangerous and could puncture your skin. 2. Corset bones are there in the corset to support the fabric; not to exert any pressure on you for figure reduction. It is the cut of the fabric that produces the shape, but bones stop the fabric from crinkling, or gathering into your waist as the tension is applied. That is why commercial bones are specially made to be fairly lightweight, flexible in the right directions for your figure, and will not rust or otherwise deteriorate with wear or careful cleaning. So go for easiest you can get from the Net. That's my advice. OK?
- Q: I like non-stick cookware but it dont hold up no matter how much money you spend. What isthe best kind? Is there something better then stainless steel or iron skillet? I do not care if I have to use extra elbow grease to clean a pan.
- Some utensils are both cookware and bakeware. The choice of material for cookware and bakeware items has a significant effect on the item's performance , particularly in terms of thermal conductivity and how much food sticks to the item when in use. Some choices of material also require special pre-preparation of the surface - known as seasoning - before they are used for food preparation. Stainless steel cookware is a great choice for safe cooking. Many kinds of cookware react with the foods, either changing the taste of the food or even releasing harmful materials into the food that can cause imbalances or diseases. Many non-stick coatings like teflon are safe - but once they get scratched or overheated they can start to leak chemicals in the food that are according to some scientific studies dangerous and possibly carcinogenic. Both the cooking pot and lid handles can be made of the same material, but will mean that when picking up or touching either of these parts oven gloves will need to be worn. In order to avoid this, handles can be made of non heat conducting materials, for example bakelite, plastic or wood. It is best to avoid hollow handles because they are difficult to clean or to dry.
- Q: So...I'm learning about how steel is made and I'm wondering if there is a more environmentally friendy method. I view it as unfriendly b/c of the oxygen that is injected when the steel is in the blast furnace or electric arc furnace. This oxygen bonds w/ the carbon to produce CO and CO2. THis is necessary to reduce the amount of carbon content to produce harder steels. So what other methods are there that can be used w/o having to end up w/ co and co2? thanks
- From what I understand of it, US steel is better as the steel is more recycled than Canadian, so a lot of that oxygen / CO2 has already taken place compared to working from ore. The second reason US steel is environmentally ahead of Canadian is that US tends to use Electric Arc, while Canadian uses Basic Oxygen, Basic Oxygen uses more energy than electric arc, and I think it also uses more oxygen, but I would suspect that oxygen that it uses is 'waste oxygen' and not converted into Co2 because the Co2 process is limited by the carbon, and steel only has so much carbon.
- Q: What is the current value of steel? Is it expected to increase in value?
- They'd never be worth much for their steel content, likely always less than face value. They might be worth a premium as coins, but not anything you'd call an investment.
