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 the safety precautions to be taken while handling steel coils?
- Some safety precautions to be taken while handling steel coils include wearing appropriate personal protective equipment (PPE) such as gloves, safety glasses, and steel-toed boots to protect against potential injuries. It is important to use proper lifting techniques and equipment, such as forklifts or cranes, to avoid strains or falls. Coils should be stored on stable surfaces and secured to prevent them from rolling or falling. Additionally, workers should be trained on proper handling procedures and be aware of the potential hazards associated with sharp edges, heavy weight, and unstable loads.
- Q: How do the sandpaper grits compare with different coarse levels of steel wool? For example, I'm finishing a homemade entertainment center, and using a tinted polyurethane, and it says to use 000 grade steel wool, but mine is #3, could I use some sanpaper instead, and what grit?
- Steel wool and wax is for the final buff after the finish coat. Sanding will scratch the finish and should only be done before the finish coat. Steel wool and wax have been used as the final finish to remove rough areas and buff the finish for a long time.
- Q: How are steel coils protected from chemical damage?
- Steel coils are typically protected from chemical damage through the application of a protective coating or by storing them in a controlled environment to prevent exposure to corrosive substances.
- Q: a picture of the atomic structure of carbon steel
- This is actually a quite complex question... The atomic arrangement in steels can be controlled over a pretty wide range of different structures. This is really the fundamental reason why steel is such a commonly used material. The different atomic structures produce different physical properties so metallurgists have developed many different processes to control the atomic structure to get the properties they want. One simple answer is that Fe is BCC, body centered cubic at room temperature at equilibrium conditions. When you heat Fe up, it transforms to FCC, face centered cubic. If you continue heating Fe, it goes back to BCC, then it melts. The addition of C makes these structures (and the transformation temperatures) different. Deviating from equilibrium conditions by, for example, cooling very quickly (quenching) creates different atomic structures (one of the most important is known as martensite). Depending on how much C is in the steel, you can also have two different atomic structures (two different phases) present in equilibirum, for example, pearlite which is a mix of alpha Fe (BCC) and iron carbide Fe3C (orthorombic crystal structure). So... you need to think a little more about exactly what you want a picture of. I hope this helps
- Q: Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?
- Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
- Q: Can steel coils be embossed?
- Yes, steel coils can be embossed. Embossing is a process that involves creating raised or recessed designs on a material's surface, and it can be done on various materials, including steel.
- Q: I play the guitar and recently found a new type of a guitar called the steel guitar, I don't want to play it or anything it's just I've never seen anything like it before and wonder what the function of it is and what are the differences to a classical guitar
- Different okorder /. If you just like the sound, take a serious look into slide guitar, not the same, but seriously tasty.
