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.

- Q: What are the different types of steel coil loading and unloading methods used during processing?
- There are several different methods used for loading and unloading steel coils during processing. Some common methods include overhead crane lifting, forklift transportation, coil cars, and coil transfer cars. Each method has its own advantages and is chosen based on factors such as the size and weight of the coils, the available equipment, and the layout of the facility.
- Q: How are steel coils used in the manufacturing of shipping containers?
- Steel coils are used in the manufacturing of shipping containers as they are rolled into sheets, which are then cut and welded to create the walls, roof, and floor of the container. The high strength and durability of steel coils ensure that the shipping containers can withstand the rigors of transportation, protecting the goods inside.
- Q: How are steel coils inspected for thickness?
- Steel coils are inspected for thickness using various methods to ensure their quality and compliance with industry standards. One common method is using a non-contact laser measurement system. In this process, a laser beam is directed towards the surface of the steel coil, and the time it takes for the beam to reflect back is measured. By accurately calculating the time taken, the thickness of the steel coil can be determined. Another method involves using ultrasonic technology. Ultrasonic sensors are used to emit high-frequency sound waves that penetrate the coil. These sound waves bounce back differently depending on the thickness of the steel, allowing the sensors to measure the thickness accurately. Additionally, some manufacturers may opt for an eddy current testing method. This technique involves passing an alternating current through a coil, creating a magnetic field. The thickness of the steel coil affects the impedance of the coil, which can be measured. By analyzing the changes in impedance, the thickness of the steel coil can be evaluated. Furthermore, some companies employ a mechanical method called the caliper method. This method involves using a caliper gauge to physically measure the thickness of the steel coil by applying pressure to the coil and reading the measurement on the caliper. Regardless of the method used, it is crucial for steel coils to be inspected for thickness to ensure they meet the required specifications and provide the desired performance in various applications.
- Q: Which one has more electrical resistivity? Wood or steel? And why?I know that the resistivity depends on the material of the conductor, but i want a perfect explaination please.Thnx in advance :)
- Wood is made up of elements which are non-metals with a high electron affinity. Specifically, carbon, oxygen, hydrogen, and some nitrogen. Furthermore the covalent bond structure in wood means electrons are tightly bound and cannot move easily from atom to another. Not without adding a great deal of energy to the first. Steel is mostly iron, which is a metal. Metals have low electron affinity. The outer electrons in metals are bound very loosely, so that they can move from atom to atom using almost no energy. Metals tend to conduct electricity very easily.
- Q: How are steel coils cut and shaped for specific requirements?
- Steel coils are cut and shaped for specific requirements through a process called slitting and forming. Slitting involves unwinding the coil and passing it through a set of rotary knives that cut it into narrower strips. These strips can be further cut or shaped using tools such as shears, blades, or presses to meet the desired dimensions and specifications. The shaping process may involve bending, rolling, stamping, or welding the strips to achieve the required form. Overall, precision machinery and skilled operators are key in ensuring steel coils are cut and shaped accurately for specific needs.
- Q: How are steel coils used in the production of metal signs?
- Steel coils are used in the production of metal signs as they are processed and shaped into flat sheets that serve as the base material for the signs. These coils are unrolled and flattened, then cut and formed into the desired shape before being painted or coated for aesthetics and protection.
- Q: Does a magnet stick to galvinied steel?
- yes it does. The steel below the galvanized coating still has a relative high carbon content and magnets stick to it. Magnets do not stick to stainless steel very well though. There is a weak attraction there. If I recall correctly this is due to the relatively low carbon content and the higher content of chromium.
- Q: Why can't you use a lead shot only choke with steel shot or a steel shot only choke with lead shot? I have used a lead only choke with steel shot and my shotgun shot fine and there was no damage to the choke.
- You should not have done this. It not a matter of shooting fine - it's a question of getting the correct distance and shot pattern SAFELY. Lead only chokes squeeze the lead shot a considerable bit. Lead is compressive and soft - it takes more squeeze to get the correct patterns from a shotgun. Steel only chokes do not squeeze as much as the lead version because the steel is very had and does not compress well. When you accidentally shoot lead through a steel chock the pattern will be weird. But, it usually is not an unsafe condition. However, steel through a lead choke will cause unsafe pressure at the choke and can explode. You end up with a bugs bunny/road runner cartoon looking shotgun! Most gun shops all over the USA are decorated with these blown up shotguns from people doing exactly what you did. Unless you want to add yours to the other dead gun collection in some shop - I recommend you take your shotgun and all your chokes into a gun smith and have him look it all over. See if anything is out of tolerance. Guns are not fool proof. If you do not follow the instructions and operate them safely they will blow up and tear a piece of your body off. Just ask any ER doctor or long time shooter.
- Q: Steels like YHB-2, MVS-8, and SK-5. Also if you know anything about these steels that would be helpful.
- White steel is a common shorthand name for white paper steel (shirogami hagane) which can be any of several fairly simple high carbon, water hardening steel grades. The carbon content varies by grade, and runs from 0.8 to 1.4%. The range of carbon content within a grade is a tight 0.1%. For example, the carbon content of Shirogami Hagani No1A is specified to be between 1.3 and 1.4%. Each grade also contains 0.1-0.2% silicon and 0.2-0.3% manganese, and only trace amounts of the impurities sulfur and phosphorus. Blue paper steel (aogami hagane) is also offered in several grades, with carbon content ranging similarly to the white grades. However, blue steel contains the additional alloying elements chromium and tungsten, and one grade (aogami super) also contains molybdenum and vanadium. The blue steels can be quenched in water or oil, whereas most of the white grades need a faster quench and require water.
