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.
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: How are steel coils inspected for hardness?
- Various methods are used to inspect the hardness of steel coils, ensuring their quality and suitability for specific applications. The Rockwell hardness test is a common method, involving the use of a diamond or ball indenter pressed into the coil's surface to measure indentation depth. The hardness value is then determined based on this measurement. Another method is the Brinell hardness test, which uses a hardened steel or tungsten carbide ball indenter to create an indentation on the coil's surface. The diameter of the indentation is measured, and the hardness value is calculated using a formula that considers the applied load and indentation diameter. On the other hand, the Vickers hardness test utilizes a pyramidal diamond indenter to create an indentation on the coil's surface. The lengths of the indentation diagonals are measured, and the hardness value is calculated using a formula that takes into account the applied load and diagonal lengths. In addition to these traditional methods, modern technology has introduced non-destructive testing techniques such as ultrasonic testing and eddy current testing. Ultrasonic testing involves transmitting ultrasonic waves through the coil and measuring the time it takes for the waves to return. Changes in the wave pattern can indicate variations in hardness. Eddy current testing, on the other hand, uses electromagnetic induction to detect changes in electrical conductivity, which can be correlated to hardness variations in the steel coil. Overall, steel coils undergo thorough inspection using a combination of traditional and advanced techniques to ensure their hardness meets the required specifications. These inspections are vital in maintaining the quality and dependability of steel products in various industries.

- Q: Hello people.Me and the life mate have been working on a fantasy book together and we are currently in the process of outlining the cultures. The culture of our antagonists' is a sort of woodland tribal/celtic[ish] deal and they are very nature oriented. Being a detail freak and wanting to have some real world credibility in the story, I am trying to decide how they produce steel. I want steel to be an important part of the culture, but a thing that is in limited supply. I also do not want there to be a large amount of resources committeded to mining or processing iron ore for steel. So does anyone have any real world ideas explaining how the people can produce steel without using underground mining operations, large processing facilities, and without raping the land?All help and ideas are appreciated
- Well, steel is just modified iron, so you're going to have to start with acquiring the iron first. For that, you're most likely going to be using some sort of underground mining somewhere - either they do that themselves, or they purchase the iron elsewhere. Assuming you're not dealing with meteoric iron (which is possible, but pretty uncommon), or iron sands (not likely in a woodland area), then unless you're dealing with a rocky outcropping with iron veins out in the open, I'm pretty sure there needs to be somebody doing some digging. That said, it doesn't need to be a full raping of the land scenario. A couple of minor mines, some small-scale smelting operations, and somebody knowing the secret of making steel, and it could give you small amounts of steel without making an ecological disaster.
- Q: What are the main challenges in handling and processing steel coils?

- Q: I just got my Daewoo K2 in 5.56 and i know they are tough and reliable but how well will it fair with steel rounds. I know shooting brass is better for any gun but what kind of extra wear and tear would i be looking at with shooting steel. Also what about reloading steel. Is it recomended. I would not even be asking this but steel is far cheaper than brass ammo, and i need to save some money.
- Definitely DO NOT reload steel cases. As far as shooting steel vs brass. Brass will always be better than steel in your gun. Steel is a harder and stronger metal and will wear the firearm quicker than brass.
