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.

- Q: Ok I have a neodymium magnet, stuck to my fridge holding a old bottle cap opener for my beer it works fine. At the local rummage sale there was a beautiful cap opener my freind was selling for $0.25 she said had never beenUsed it was like 40 years old it is made a stainless steel. The magnet will not stick to it. I don't understand this looked this up and certain steels are not magnetic, I tried a experiment with my compass it don't point north as should it follows the bottle opener as I move it around it. If not magnetic why is this happening? Also tried placing near another neodymium magnet with a pull of about 200 lbs. Not I tiny bit of attraction to the metal. If so why is the tiny magnet in the compass attracted to it. But not a huge powerfull magnet.
- That's interesting that it caused deflection in the compass. A lot of stainless steels may be SLIGHTLY magnetic, because they have small amounts of ferrite or alpha-iron in them. Ferrite is one of the crystal phases of steel. It has a body-centered cubic (BCC) structure and it's responsible for the magnetism of ordinary steels. Adding certain elements like nickel, manganese, or molybdenum, changes the crystal structure of the steel to a face-centered cubic (FCC) structure, which is NOT magnetic. This crystal phase is known as Austenite or gamma-iron. However most iron alloys contain some impurities that may cause the steel to be not completely transformed into the FCC austenite phase, small areas remain as ferrite.
- Q: I need to know which cookware set is better. We are trying to get rid of the ones we have here. They are Teflon. I have heard that stainless steel (aluminum) and hard Ionized are good, but which is the best one.
- I have a set of Stainless and individual pots and saute/frying pans that are non-stick. Calphalon is a good brand and should serve you well for now. They are easy to clean and work well for most dishes. If I looked at the right set of pots, these should also be oven safe which is great for stews and roasts. If you get into cooking you will probably want to purchase some stainless for preparing sauces. The fond (which is the basis for many quick sauces) from meat, poultry and fish will not accumulate on non-stick pans as well as stainless pans.
- Q: What are the different steel coil surface treatments?
- The different steel coil surface treatments include mill finish, galvanized, galvannealed, painted, and coated with various materials such as zinc, aluminum, or polymer.
- 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.
