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: What are the challenges in coil recoiling for high-strength steel?
- There are several challenges associated with coil recoiling for high-strength steel. Firstly, high-strength steel is known for its increased hardness and strength, which makes it more difficult to coil compared to regular steel. The higher tensile strength of high-strength steel puts more stress on the recoiling equipment, leading to potential damage or failure of the machinery. Secondly, high-strength steel tends to have lower ductility, meaning it is less able to withstand deformation without fracturing. Recoiling high-strength steel coils requires careful handling and control to prevent any excessive bending or stretching that could cause the material to break or crack. Another challenge is the shape memory effect of high-strength steel. This phenomenon causes the material to return to its original shape after being deformed. While this property can be advantageous in some applications, it complicates the recoiling process as the steel coil may resist being reshaped into a new coil form. Furthermore, high-strength steel often has a more complex microstructure compared to regular steel, with different phases and grain boundaries. This complexity can make the recoiling process more challenging as it may affect the material's mechanical properties and response to deformation. Lastly, the surface finish of high-strength steel coils is critical for many applications. Recoiling can introduce surface defects, such as scratches or marks, which may affect the functionality or appearance of the final product. Therefore, maintaining a high-quality surface finish during the recoiling process is a significant challenge. In summary, the challenges in coil recoiling for high-strength steel include the increased stress on recoiling equipment, lower ductility, shape memory effect, complex microstructure, and the need for a high-quality surface finish. Overcoming these challenges requires specialized equipment, precise control, and careful handling to ensure the integrity and quality of the recoiled high-strength steel coils.
- Q: Suppose you made a sword out of diamond (just follow me here, it's only theoretical). Would it be lighter than a sword of the same size made out of steel?
- The weight of steel is dependent among what kind of steel, shape, length, width, thickness a 5mm by 5mm ball of carbon steel would wiegh 1.69969 g a same size diamond weighs .79 carats equivelent to 1.5 grams So the basic answer is, yes, diamond is lighter than steel, but barely
- Q: How are steel coils used in the production of roofing systems?
- Steel coils are used in the production of roofing systems in various ways. Firstly, the steel coils are unrolled and fed into a machine where they are cut to the desired length for the roofing panels. These coils are often made of galvanized steel, which is coated with a layer of zinc to protect against rust and corrosion. Once the coils are cut, they are then passed through a roll-forming machine. This machine shapes the steel into the required profile for the roofing panels. The shape of the panels can vary depending on the design and functionality of the roofing system. After the steel is formed, it may undergo further processes such as embossing or stamping to add texture or patterns to the panels. This helps to enhance the aesthetics of the roofing system and provide a unique look. The formed and processed steel panels are then coated with additional protective layers or finishes, such as paint or polymer coatings. These coatings further enhance the durability of the roofing system and provide resistance against weather elements, UV rays, and corrosion. The final step in the production of roofing systems involves the installation of the steel panels on the roof. The panels are typically fastened to the roof structure using screws or nails. The interlocking design of the panels ensures a secure and watertight installation, providing protection against leaks and moisture infiltration. Overall, steel coils play a crucial role in the production of roofing systems by providing a durable and long-lasting material that can withstand harsh environmental conditions. The versatility of steel allows for various design options and customization, making it a popular choice for roofing applications.
- Q: I am making a sword of 1060 carbon steel and would like to know how to heat treat it once it's ready, could anyone help please?
- Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
- Q: Is steel easier to weld?Which is more brittle/less flexible?
- I can't weld steel to aluminum, and generally speaking I'd say the answer is no, however, there are some special procedures that can make a metallic bond between steel and aluminum, it can be done with explosive welding. A lot of multi-ply cookware is made with aluminum sandwiched between stainless steel, there is so much of it that I imagine there is another way besides explosives, but I don't know what. In any case it is not a normal workshop procedure. Steel is often considerably easier to weld, but it depends on the alloy. some steels are difficult to weld and some aluminum alloys are fairly easy, but on the average steel is easier. as far as brittle/ flexible it again depend on the alloy, some steels are less brittle than some aluminum alloys and the other way around. Steel does have a higher modulus of elasticity, so for a given size steel is stiffer, but that is for elastic deformation, for plastic deformation steel often has a higher yield strength, but some of the more exotic aluminum alloys can be stronger than low grades of steel.
- Q: Im in the process of replacing the gutters/down spouts on my house. The top of the house is four sided. The bottom level has a porch area with 3 sides, two smaller roofs in the back, and one small roof on the side with all stainless steel gutters. A two story house. Not sure of the demensions. They were made at a Steel Mill where the previous owner, worked.This guy wants to buy the stainless gutters but I need to know the market value of this steel and offer him a price. Can someone tell me what I can sell it for? Does it go by the pound? Foot? Can you give me an idea please? Theres a lot of it! I have no clue what to do! Thanks!
- Steel is at an all time high of $3.99 per hundred pounds..Stainless will sell for more....I haulled a pickup truck full 3 days ago and got over a 100 bucks for junk I had laying around the yard.
- Q: I want to save water $$, so I want to use frozen steel to cool my coke. possible or no?
- Hey man, don't you think it would save more $$$ to cool your coke in the fridge than trying to cool steel? How do you plan on cooling the steel? And you can't freeze steel but you can make it cold. You are just joking right, I hope so anyway?
- Q: What are the different packaging options for steel coils?
- There are several packaging options for steel coils, including wooden crates, steel frames, and metal or plastic bands. These packaging options help to protect the coils during transportation and storage, ensuring their integrity and preventing damage.
- 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.
- Q: Can steel coils be used in the production of furniture?
- Yes, steel coils can be used in the production of furniture. Steel coils can be used to create sturdy frames for furniture such as chairs and sofas. The coils can be shaped and welded together to provide support and durability to the furniture.
