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:Which steels were origianally designed to be used to cut and shape metals and other materials?- alloy steel- high carbon steel- carbide steel- tool steelthanks
- In your choices carbide steels are used for milling and drilling purposes and high speed steel are used in lathe operations. For shaping the tools, tool grinding machines are used and for initial sharing dyes are used.
- Q:I was wondering what material most common motorcycle gas tanks are made out of? is it steel? stainless steel? aluminum? what are the advantages and disadvantages or each?
- Aluminum Motorcycle Gas Tank
- Q:How are steel coils used in the manufacturing of agricultural structures?
- Steel coils are used in the manufacturing of agricultural structures as they provide the necessary strength and durability required for building structures such as barns, grain storage facilities, and equipment sheds. These coils are often used to fabricate beams, columns, and trusses, ensuring structural stability and resistance to harsh weather conditions. Additionally, steel coils are also used in the production of agricultural machinery and equipment, further enhancing the efficiency and reliability of farming operations.
- Q:I am buying a knife for my future husband for his wedding gift and I was wondering what is better carbon steel or stainless steel?
- carbon steel is my choice. googlecarbon steel vs stainless steel knives for more info. If you buy stainless make sure it is an alloy that will hold an edge..many a shiny knife is just a dull dud. Carbon blades don't rust unless they are left laying in the wet. I was having this conversation with a Friend once. So I took his knife and struck his knifes edge against mine with a light blow.. His had a 1/16 dent in it, mine not even a mark on it. I assume this is not a kitchen knife.
- Q:i am debating weather to get the hercules rmx or the steel and from what i have read, the only differences between them is the rmx has a sound card (built in interface-to connect to the computer, correct me if im wrong) and that the steel has more effects. however, i cannot find out which effects it has so it would be a big help if someone can answer this for me.thanx
- I guess that since Steel doesn’t have headphones connection and a built-in soundcard, one won’t be able to play a track on one deck and prelisten the track on the other without using an external usb soundcard, right? I was wondering what’s the point in releasing a product like this if you also have to buy a bunch of equipment to be able to do sth “fondamental”: play while preparing your next song. However since the steel is meant for DJ’s who already have a great soundcard, but I don’t see why a Steel+sound card is ONLY for pro’s. Yes it’s designed for pro’s but you can use it as a beginner. Some consoles you also need to consider: Hercules Steel/RMX, Numark OMNI/Steath. It's all personal decision. Peace, Love Happiness
- Q:What are the weight ranges for steel coils?
- The weight ranges for steel coils vary widely depending on the specific type and purpose of the coil. Generally, steel coils can range anywhere from a few hundred pounds to several tons in weight.
- Q:ex: boat hull made out of steel
- egg yolk. it really works. i know this because i built a surfing bicycle (yeah) that had steel on it.just let the steel soak in the yolk for about 3-4 hours and let it dry in a dark area. this will work.
- Q:I am wondering if i can use my western guitar as a kind of steel-guitar, read something about it on Wikipedia.
- If you decide to get a true pedal steel, plan on spending some big money. Look on eBay for a Carter Starter. It will be the best guitar to start on...and not outgrow too fast.
- Q:What are the challenges in coil leveling for coated steel?
- To achieve high-quality, flat, and smooth coils, several challenges must be addressed in the process of coil leveling for coated steel. The first challenge lies in the potential damage to the coating during leveling. Coated steel coils are typically covered with materials like zinc or paint, which are susceptible to scratching or marring if mishandled. The leveling process involves passing the coil through a series of rolls, which can cause friction, abrasion, or other mechanical harm to the coating. Therefore, it is crucial to meticulously control the speed, pressure, and alignment of the rolls to minimize coating damage. The second challenge stems from the variations in thickness across the coil. Coated steel coils often exhibit thickness discrepancies due to inherent material properties or production methods. These variations can lead to uneven leveling, resulting in coils with waviness or inconsistent flatness. Achieving uniform leveling across the entire coil surface is vital to ensure consistent quality and appearance of the final product. Another challenge in coil leveling for coated steel is the possibility of shape distortion. The coating processes can introduce stresses into the steel, causing the coil to warp or distort during leveling. This distortion can lead to coils with irregular edges or uneven flatness. Proper control of leveling process parameters, such as the number of passes and applied tension, is necessary to minimize shape distortion. Furthermore, the coil leveling process can generate internal stresses in the steel, especially in cold-rolled or heat-treated coated steels. These internal stresses can result in coil spring-back, where the coil attempts to revert to its original shape after leveling. Spring-back can cause coils with undesired curvature or inconsistent flatness. Effective strategies, such as stress relief annealing or employing counteracting leveling techniques, are essential to minimize spring-back and achieve the desired flatness. Lastly, handling and storing coated steel coils pose challenges in maintaining the quality of the leveled coils. Coated steel coils are sensitive to environmental conditions, such as humidity, temperature, and exposure to corrosive substances. Proper storage and handling practices are crucial to prevent coating damage, rust, or other forms of deterioration that can occur during transportation or storage. In conclusion, the challenges in coil leveling for coated steel involve minimizing coating damage, addressing thickness variation, controlling shape distortion and spring-back, and ensuring proper handling and storage. Overcoming these challenges necessitates precise control of process parameters, the application of suitable leveling techniques, and strict adherence to quality control measures throughout the entire process.
- Q:like, what can steel make?
- buildings bridges automobiles elevators railroads and railroad equipment appliances and many many more. Steel is used almost everywhere. reference: Iron and steel are used widely in the construction of roads, railways, infrastructure, and buildings. Most large modern structures, such as stadiums and skyscrapers, bridges, and airports, are supported by a steel skeleton. Even those with a concrete structure will employ steel for reinforcing. In addition to widespread use in major appliances and cars (Despite growth in usage of aluminium, it is still the main material for car bodies.), steel is used in a variety of other construction-related applications, such as bolts, nails, and screws.[66] Other common applications include shipbuilding, pipeline transport, mining, offshore construction, pipeline transport, aerospace, white goods (e.g. washing machines), heavy equipment (e.g. bulldozers), office furniture, steel wool, tools, and armour in the form of personal vests or vehicle armour (better known as rolled homogeneous armour in this role). .
