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: The guy at this one pawn shop told me that stainless steel is better because it is just as strong and will not rust. The guy at the other pawn shop said that you need high carbon steel for a good sword because stainless steel breaks easily and that damascis is the best kind of steel for swords.
- Modern Sword Steels: Stainless - Used in decorative swords and knives. Stainless steel blades longer than twelve inches are too brittle for full contact use. 1045 Carbon - Strong, but soft compared to higher carbon steels. Reasonably cheap and acceptable for full contact use. 1060 Carbon - Harder than 1045, but not brittle. Holds a keen edge and is very durable. Somewhat expensive, but great for full contact use. 1095 Carbon - Sacrifices the durability of lower carbon steels for better edge retention and increased hardness. Somewhat expensive, but tough enough for full contact use. 5160 Spring - Extremely tough and durable. Great for full contact use when properly heat treated. 9260 Spring - Amazingly resilient and durable, but not unbreakable. Excellent for full contact use. T10 Tool - Exceptionally hard and tougher than other steels with similar carbon content. Keeps a good edge without sacrificing durability. Can be expensive, but is still great for full contact use. L6 Bainite - Can be very expensive, but is the toughest steel on the market when properly heat treat. Excellent for full contact use, but requires additional maintenance to prevent rust and corrosion. About Damascus Steel: Historical Damascus blades were made from wootz, an Indian steel with unique properties. The technique for making this type of steel has been lost, but there have been many attempts to recreate it. The patterns found on Damascus steel blades are a direct result of the sword-making process and are not entirely dependent on the type of steel used. Damascus swords were the finest blades of their time.
- Q: How are steel coils processed and treated?
- Steel coils are processed and treated through a series of steps. Initially, the steel is cleaned and pickled to remove any impurities. It is then passed through a series of rolling mills to reduce its thickness and increase its length. The coils are then annealed to improve their strength and ductility. Further treatments such as galvanizing or coating can be applied to enhance corrosion resistance or improve aesthetic appeal. Finally, the coils are cut and packaged according to customer specifications before being shipped for various applications in industries such as construction, automotive, and manufacturing.
- Q: What is the average amount carbon emissions of steel per pound produced?
- Carbon okorder /... - Similar pages - Life-cycle energy and emissions of marine energy devices | Carbon ...Carbon dioxide emissions per unit mass of steel: 1.75 tCO2/tonne steel ; Total mass of steel in device: 665 tonnes ; Carbon dioxide emissions due to .
- Q: What are the dimensions of steel coils used in the structural component industry?
- The dimensions of steel coils utilized in the structural component sector are subject to variation, contingent upon the particular application and specifications. Nevertheless, standard dimensions for steel coils in this industry encompass a width that ranges between 600mm and 2000mm, as well as a thickness that spans from 0.25mm to 10mm. The weight of these coils may also differ, typically ranging from a few kilograms to numerous tonnes. Furthermore, the length of the steel coils can be customized to fulfill the specific demands of the structural component industry, with commonplace lengths including 2000mm, 2500mm, and 3000mm. It is vital to acknowledge that these dimensions are not exhaustive and are susceptible to variation based on the specific product and manufacturer.
- Q: What are the different methods of protecting steel coils from corrosion?
- Some common methods of protecting steel coils from corrosion include applying a protective coating or paint, using corrosion inhibitors, implementing cathodic protection systems, and storing the coils in a controlled environment with low humidity and proper ventilation.
- Q: What are the common coil coating methods?
- The common coil coating methods include roll coating, curtain coating, and spray coating.
- Q: A roll of 1 meters wide color steel roll about how many tons?
- Color steel roll is a composite material, both steel and organic materials, both of them a little. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance. 1 meters wide should also have length, wall thickness conditions to know how many tons. The manufacturer is generally in accordance with customer requirements into a volume, the normal width of 1 meters per roll over 1 tons.
- Q: i need the same kind of body jewelry they use in the piercing shop but when i go to order them they say stainless steel, not surgical steel, and i have REALLY sensitive skin so i need to be sure, whats the difference?
- There are hundreds of different grades of stainless steel. Jewelery used for piercings should be made of implant grade. Note that the term surgical steel is not a technical term. It doesn't mean anything, although it sometimes refers to what is technically implant grade stainless. Implant grade stainless steel must conform to the ASTM standard 316LVM F-138-00, otherwise the seller cannot call it implant grade. This is something you should always ask about specifically. Are your stainless items F-138-00 compliant? Jewelry that only claims to be stainless isn't good enough. Jewelery sold in mall stands are typically nickel plated, bargain-basement low grade stainless. Allergies to nickel are common.......BUT there is a big difference between allergies, and infections. Infections are caused by bacteria, not by the metal itself, and if you're getting infections it's a sign you're not keeping the piercing clean and sanitary. Simply switching to a different metal won't prevent infections from recurring. To prevent infections you need to take steps to keep new piercing clean and sanitary. the best way to do this is rinse with 50:50 hydrogen peroxide and water daily, then apply some neosporin. hope this helps.
- Q: What are the different methods of coil recoiling for narrow strip widths?
- Some of the different methods of coil recoiling for narrow strip widths include slitting and rewinding, oscillating winding, and turret winding.
- Q: can u use stainless steel to make a coin? why or why not? answers based on facts plz.
- Stainless steel has been used by some countries to make coins, but it's not an ideal metal. When a coin is struck, a die comes down and strikes the blank with many tons of force (the blank is also sitting on top of another die--one has the image on the obverse (front) of the coin, while the other die has the image of the reverse of the coin). When the die strikes the blank, the force causes the metal in the blank to flow into the recesses of the die. The problem with stainless steel is that it doesn't want to flow into the die. To get an image, either the relief (how high the raised portion of the design will be) has to be very low, and the coin has to have a simple design, or they have to greatly increase the pressure of the strike. This slows the coining press down, and greatly shortens the life of the dies.
