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.
Applications of Prepainted Rolled steel Coil for Construction Roofing
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

- Q: What are some characteristics of steel.
- Characteristics Of Steel Hardening. - The characteristic difference between steel and pure wrought iron is as follows: - When steel is raised to a red heat and then suddenly cooled, it becomes hard and brittle. This process, which is known as hardening, has no effect upon pure wrought iron. Tempering is a characteristic of steel which distinguishes it from cast iron. If steel has been hardened by being heated and suddenly cooled, as above described, it may be softened again by applying a lower degree of heat and again cooling. This is known as tempering. Cast iron, on the contrary, though it is hardened by the first process, cannot be softened by the second. When a bar of steel is struck it gives out a sharp metallic ring, quite different from the sound produced by striking wrought iron. Other characteristics of steel are its great elasticity and its retention of magnetism.
- Q: How are steel coils processed for slitting or edge trimming?
- Steel coils are processed for slitting or edge trimming by first being unwound from the coil and passed through a series of rollers to ensure a smooth and uniform surface. The coil is then cut into narrower strips using a slitting machine or trimmed along the edges to remove any imperfections or excess material. This process helps create precise and customized steel strips that can be used for various applications.
- Q: Is steel with a black coloring as strong as regular steel. if you are asking why i have two wordsBlack Katana.I know a katana is not made with normal steel, it is made of two types with varying grades of carbon to give it speacial properties, i just want to know if the black will make a difference.
- There are many types of steel some very rigid, while you can have steel that is very flexible. The type of katana: steel is for Samurai swords
- Q: How do steel coils contribute to corrosion resistance in products?
- Steel coils contribute to corrosion resistance in products through a combination of factors. Firstly, steel coils are often made from stainless steel, which contains a high amount of chromium. Chromium forms a protective oxide layer on the surface of the steel, known as a passive film, which acts as a barrier against corrosion. This passive film is self-healing, meaning that if it gets damaged or scratched, it can regenerate itself, ensuring continued protection against corrosion. Additionally, steel coils undergo a process called galvanization, where a layer of zinc is applied to the surface of the steel. This zinc layer acts as a sacrificial anode, meaning that it will corrode preferentially to the steel. This sacrificial corrosion protects the steel underneath, effectively preventing rust and other forms of corrosion from developing. Moreover, steel coils can be coated with various protective coatings, such as epoxy or polyurethane, to further enhance their corrosion resistance. These coatings provide an additional physical barrier that prevents moisture, chemicals, and other corrosive elements from reaching the steel surface. Lastly, steel coils can be manufactured with specific alloying elements, such as nickel or molybdenum, which further improve their resistance to corrosion. These alloying elements enhance the strength and durability of the steel, making it better able to withstand corrosive environments. Overall, steel coils contribute to corrosion resistance in products by utilizing stainless steel, galvanization, protective coatings, and alloying elements. By implementing these measures, steel coils ensure that products maintain their structural integrity and appearance over time, even in harsh and corrosive conditions.
- Q: What are the quality standards for steel coil production?
- The quality standards for steel coil production typically include factors such as dimensional accuracy, surface finish, mechanical properties, chemical composition, and adherence to industry-specific standards and specifications. These standards ensure that the steel coils meet the required strength, durability, and performance criteria, and are suitable for various applications in industries like automotive, construction, and manufacturing.
- Q: what is the densest type of steel ? what is its density ?what is its tensile strength .
- Agree okorder . If you are really looking for higher density, go to copper or tungsten.
- Q: How are steel coils used in the production of steel clamps?
- Steel coils are used in the production of steel clamps as they serve as the main raw material for creating the clamps. The steel coils are first processed and transformed into the desired shape and size through cutting, bending, and shaping processes. These coils are then formed into the clamp's body, providing the necessary strength and durability. Overall, steel coils play a crucial role in manufacturing steel clamps by providing the essential material for their construction.
- Q: So I want to get my 3+ wood shafted with a dynamic gold shaft because i need a stiffer shaft but dont want to spend much on it.I've never swung a steel shafted wood, but I hear that it is more consistent that graphite....Plus, since the cost of steel is only $15 compared to the $65 graphite, not to mention installation charges.So yeah...... How good is steel for fairway woods?BTW, my swing speed is about 95 but i can amp it up to 110 (with control, that is)
- If your club has a graphite shaft in it and you want to switch to steel an option is to get a dynamic gold lite shaft. The other option is to make sure you trim the shaft to the 42 length with the gold shaft to lighten up the swing weight. You can get away with about 42 3/4 with the lite shaft. I have found steel to be very consistent in my fairway woods and don't think I'll ever go back to graphite. I have mine cut to 42 1/2 for the 3 wood and 41 1/2 for the 5 wood with Dynamic gold s300 and they're fine.
- Q: I need help my new stainless steel cookware is sticking ? My first meal was nasty!
- One of two things can cause this. Either your pan bottoms are light weight, or you are cooking at too high a temperature.
- Q: 1943 steel pennies
- You really don't want to do anything to to them. If they're rusty, that's just the way they are now. Store them in a dry place. Cleaning will do more damage than good, and will hurt the value. If it were possible to undo the damage, our cars would never rust, iron pipes wouldn't pit, and everything would be made of steel. Don't let it worry you, they're still worth having.
