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: Many gerber knives are made out of what gerber calls high Carbon steels and I was wondering if anyone knew exactly what is this mysterious steel.
- Carbon, when added to steel increases the hardness of the metal. The higher the carbon content the harder(pure carbon = diamond) the blade will be and the longer it will hold its sharpened edge. Too much carbon however can make it too brittle to use as a blade. iron, carbon and chromium(for the stainless in stainless steel) mixed in the right portion makes a high carbon stainless steel knife. All of which is kinda pointless if the blade is not forged correctly.
- Q: What are the different types of steel coil processing equipment?

- Q: So I'm trying to decide which is better. I've always had aluminum on my 6 yr old tb gelding as I do hunters on him. He's never had steel on but I've recently moved and the shoer here is more expensive. So is aluminum really worth the extra cash to keep him light on his feet or is steel really not that much different?
- It really depends on your horse. If you horse is a good mover, and average weight steel shoe shouldn't make much of a difference. If the horse is a mediocre mover, sometimes the added weight will make it move worse. You should also understand that one steel shoe is not like another steel shoe- they come in different widths of web and thickness of steel. Some horses that don't do well in regular shoes do better in a light rim shoe or training plate. Discuss your concerns with your farrier, but he/she doesn't have a crystal ball. You may just have to try steel for a cycle and see how your horse does. When I am shoeing a horse that needs lighter weight steel, I tend to use either St. Croix's Lite Rim shoe or steel Concord training plate, or Kerckaert's DR training plate or the Triumph Lite steel shoe. All of these shoes are light weight, have decent traction and good break over.
- Q: I just purchased this Benchmade knife with m390 steel blade and it cost me a fortune but I wanted to know if this new steel is a tool steel. what classifies a tool steel. M390 = 1.9 carbon, 20. chromium, .30 manganese, 1. molybdenum, .60silicon, .60 tugsten, 4. vanadium at 60-62 HRC
- Not all tool steels work well in knife blades, but some of them are very popular. D2, M2, M4 and many others.
- Q: How are steel coils inspected for paint adhesion using adhesion testers?
- Steel coils are inspected for paint adhesion using adhesion testers in a systematic and rigorous manner. Adhesion testers are devices specifically designed to evaluate the bond strength between the paint and the underlying steel surface. The inspection process begins by selecting representative samples from the steel coils. These samples are usually cut into smaller sections, ensuring that they are free from any defects or surface irregularities that could affect the adhesion test results. Once the samples are prepared, the adhesion testers are employed to measure the force required to detach the paint coating from the steel surface. The most commonly used adhesion tester is the cross-cut adhesion tester. This device consists of a set of blades arranged in a grid pattern. The blades are used to create a series of cuts through the paint coating down to the steel surface, forming a grid of squares or rectangles. After the cuts are made, a specialized tape is applied to the grid area and pressed firmly onto the surface. The tape is then rapidly pulled off at a 90-degree angle to the surface. The force required to remove the paint coating from the steel is measured and recorded. The results of the adhesion test are evaluated based on predetermined standards or specifications. These standards typically define the minimum acceptable adhesion strength for the specific application or industry. If the measured adhesion strength falls below the specified threshold, it indicates poor paint adhesion, which could lead to issues such as paint delamination or corrosion. In addition to the cross-cut adhesion tester, other adhesion testing methods may also be used, such as the pull-off adhesion tester, where a hydraulic or mechanical device applies a tensile force to a small circular or dolly-shaped test area. The force required to pull off the dolly is measured and used to assess the paint adhesion. Overall, the use of adhesion testers ensures that steel coils are thoroughly inspected for paint adhesion. This helps to identify any potential adhesion issues early on, allowing for appropriate remedial measures to be taken to ensure the longevity and performance of the paint coating.
- Q: i see a lot of connexes say repair only with corten steel. what is the difference between corten steel and regular steel. and if i was going to stick weld it what type of electrode would i use?and while i'm at it what is the best electrode to use when welding galvenized steel?
- 6010 and 6011 Electrodes for welding galvenized steel. Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as Corten steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel is allowed to rust in order to form the 'protective' coating. For welding corten steel: 1A.W.S ClassificationE 7018 - 1AWS A 5 - 1 - 78 2IS classificationE 5424 JXIS 814 (Part I II)H 3BS classificationE 51.54 B 12 17HBs 639 - 1976
- Q: What are the different types of surface finishes for steel coils?
- Steel coils can be finished in various ways, each with its own unique properties and advantages. Here are some of the most common surface finishes for steel coils: 1. Hot Rolled: Achieved by heating the steel and rolling it, this basic finish results in a rough and scale-like appearance with varying levels of imperfections. 2. Cold Rolled: This finish is obtained by subjecting hot rolled steel coils to a series of cold rolling operations. It yields a smoother and more uniform surface with improved dimensional accuracy and surface quality. 3. Galvanized: In this process, a protective layer of zinc is applied to the steel coil's surface, offering excellent corrosion resistance. It is ideal for outdoor applications and environments exposed to moisture and corrosive elements. 4. Stainless Steel: Stainless steel coils have a distinctive finish due to the presence of chromium, which forms a thin, invisible oxide layer. This finish provides exceptional corrosion resistance and an appealing appearance. 5. Electrolytically Zinc Coated: Also known as electrogalvanized, this finish involves applying a thin layer of zinc to the steel coil through electroplating. It offers good corrosion resistance and is commonly used in applications that prioritize aesthetics. 6. Pre-painted: Pre-painted steel coils have a surface finish coated with paint or other protective coatings. This finish provides corrosion resistance and aesthetic appeal, allowing for a wide range of colors and finishes. 7. Aluminized: Aluminized steel coils are coated with an aluminum-silicon alloy, providing excellent heat resistance. They are commonly used in high-temperature applications like exhaust systems or ovens. Ultimately, the choice of surface finish for steel coils depends on specific requirements such as corrosion resistance, aesthetics, durability, and heat resistance.
