Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil 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 Rolled steel Coil for Construction Roofing
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.

- Q: How are steel coils used in the production of agricultural systems?
- Steel coils are used in the production of agricultural systems as they are often shaped into various components like frames, supports, and structures. These components provide strength, durability, and stability to agricultural equipment such as tractors, harvesters, and irrigation systems, ensuring their long-term functionality and reliability in demanding farming environments.
- Q: 7850kg/cu.m density is typical for all type of steel? like reibar, I- beam and so on
- 90% of the steels used today are plain mild carbon steels consisting of iron with less than 1% carbon content and as such have a density of about 7750 kg/cubic meter. Some special steels which have a significant percentage of alloying elements such as chrome or manganese or other elements will have greater density bringing the steel up to about 8000 kg / cubic meter. There are a greater many factors influencing the exact density of a steel. Even for steels of exactly the same content of iron , carbon and other alloying elements, there may be a difference ( very small mind you ) in density due to work hardening. The difference in this case is due to movement of dislocations which become locked in the grain boundaries and this forms a more dense crystal structure. For this same reason, the theoretical density of steel (which does not take into account dislocations) is greater than the measured density of steel.
- Q: How do steel coils contribute to the marine vessel construction industry?
- The marine vessel construction industry heavily relies on steel coils as vital components. These coils, typically made of high-quality steel, are crucial for fabricating various structural elements of ships and boats. They are utilized in multiple ways to contribute to the construction and functionality of marine vessels.

- Q: Basically when i'm older, my dream Job would be, to be to start a steel mill, I've always loved the idea of working in Business and investing in things has always been a hobby of mine. i play games where u invest and make money. all i need is some facts about starting a steel mill?What requirements i need,- How time consuming is it,- How easy is it,- How to get started,- The Perks,- The downsides..how much would it cost to start one, like land, place, iron etc, to get started? also i would need a bank loan, how much money will the bank give me ? 80%??
- Typically, steel mills are worth $20 million to $200 million and are owned by large corporations. Your best bet to own one would be to take over a corporation that already has one. That way you have all the supply lines, customers, experts and other workers already there, too. Stick with investing in going concerns, so you don't need to be an expert in each business to build it up. Get them ready made, learn the details from the people already doing it, then work out ways to improve it. Do not get tempted to borrow even 10c from the scammers who have answered your question. Start saving your real money, reading the financial news, and making small real investments in real stocks.
