Description of ASTM Z80 Prepainted Galvanized Rolled Steel Coil
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 ASTM Z80 Prepainted Galvanized Rolled Steel Coil
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: I just got this aftermarket exhaust on my truck and it's recommended that it be welded, but the metal is aluminized steel. How do I mig weld aluminized steel?
- aluminized steel is just std steel with a coating applied to it to keep it from rusting. It welds just like std mild steel. You need to prep the joint and thats it. Use a wire wheel, brush, sandpaper or what ever to clean the joint of the pipes where you will weld. You don't have to get too crazy here. Just a quick brush/wipe with sand paper over the joint and your ready to weld. For mig welding, I would use a 75/25 gas mix, .023 or .030 solid steel wire, around 50-70 amp setting (on most migs this will be #2 heat setting) and around 3/10th to 4/10th wire speed. (some welders will list 0-10, others 0-100, so figure your scale, like 0-10 it would be 3-4, one that list it by 10's then it would be 30-40)
- Q: How are steel coils inspected for surface cleanliness after processing?
- Steel coils are inspected for surface cleanliness after processing through various methods such as visual inspection, magnetic particle inspection, and fluorescent penetrant inspection. These techniques help identify any surface defects, contaminants, or impurities on the steel coils, ensuring their quality and suitability for further use or shipment.
- Q: How are steel coils protected against bending and deformation?
- Various measures are implemented to safeguard steel coils from bending and deformation. One prevalent approach entails employing protective packaging materials, such as wooden crates or metal skids. These materials provide stability and support, effectively preventing any bending or deformation during transportation or storage. Additionally, steel coils are frequently tightly secured using steel or plastic bands. This measure serves to maintain their shape and prevent any shifting or movement. These bands are strategically positioned at regular intervals along the length and width of the coils, guaranteeing even pressure distribution and minimizing the risk of bending or deformation. Furthermore, steel coils can be further shielded by placing them on a flat and level surface during storage or transportation. This practice ensures the even distribution of weight, thus reducing the likelihood of bending or deformation due to uneven pressure. In certain instances, steel coils may also be coated with anti-corrosion agents. This protective coating shields against moisture and rust, which can weaken the structural integrity of the coils and lead to bending or deformation over time. In conclusion, the combination of appropriate packaging, secure fastening, and careful handling is paramount in safeguarding steel coils against bending and deformation. This comprehensive approach ensures the maintenance of their structural integrity and quality.
- Q: So here's the deal:I recently bought McCann's Instant Steel-Cut Oatmeal, and I'm wondering about any possible nutritional differences between the instant and regular stove-top. In case you haven't seen it, instant steel-cut comes in individual packets and is cooked only by adding boiling water, the same as instant rolled oatmeal (i.e. Quaker).When I asked about instant vs. stove-top rolled oats, my doctor said there are no significant nutritional differences, but since the main health appeal of steel-cut is the coarse grain, it doesn't seem possible for the finer ground instant to be as nutritious.I can't find much info about this, so any help is appreciated!
- The rationale for consuming steel cut oats rather than rolled oats (beyond the fact that the former taste really good) is the lower glycemic index. It is my understanding that in the rolled oat category, it is better to eat the long-cooking variety rather the instant for the improved fiber load and lower glycemic index. While I do not understand exactly how instant steel cut oats are processed and how much the glycemic index is affected by processing, it is safe to assume that the old unprocessed steel cut oats are still best. I always prepare 4-6 servings of the steel cut oats at one time and warm up a serving when needed to avoid having to wait 30 minutes to cook them. My rule of thumb: the less processing for any food product, the better it is for me.
- Q: What are the common applications of coated steel coils?
- Some common applications of coated steel coils include manufacturing of automotive parts, construction materials such as roofing and siding, appliances, and electrical equipment. They are also used in the production of household goods such as furniture, shelving, and storage racks. Additionally, coated steel coils find applications in the transportation industry for manufacturing trailers, shipping containers, and railway cars due to their durability and corrosion resistance.
- Q: i would like to make a dmascus steel knife, i have the cable but im not sure if its damascus steel or not, how do i tell? and if it isnt damascus steel how do i make a bar of it?
- Here's what you need, the cable should be a minimum of 9/16 with large wires. You need some borax (20 mule team from the store). A good hot coal, coke, or gas forge. If the cable has fiber rope in the center it will need to be removed. Fuse the ends of the cable to keep them from coming apart. I use my welder and while I'm at it I weld a handle to make it easier. Heat it in the forge when the forge is properly heated, rotate it. Some people will burn the oil out, but I've found that the forge does that just fine. Rotate the cable while it's heating. When it begins the turn red pull it out and sprinkle the borax over it, don't hold back use a lot. It will begin to melt and bubble into the steel. Put the cable back in the forge, rotate and watch. This is the critical part. When the steel starts to turn from orange/yellow to almost yellow/white take it out and lightly (I use a 2lb hammer) begin hammering the cable into a square or rectangle. If you do it right you'll notice that it will begin to fight the hammer, that's when you know the weld it taking place. You'll have to repeat the process down the length of the cable. Once you have the billet made you can begin the process of shaping the edge and tang. Once you have it shaped, follow proper forge procedure then grind all the yuck off and finish shaping. Then harden and temper and finish it out. Good luck. I almost forgot a very important part. Befor you start hammering put the cable in a vice while at welding temp (if you are strong you can use a couple of plyers) and twist it tight. On the next heat hold the cable in your left and and lay it on the anvil. Concentrate on your light hammer blows being on your side of the cable. This forces the cable strands together. If you are using smaller cable like 9/16 you can double the cable up and weld two peices together, it is easier and makes for a prettier blade. Doing this you don't have to worry about twisting the cable and you can hit it much harder to start with.
- Q: What are the typical dimensions of a steel coil?
- The typical dimensions of a steel coil can vary depending on its purpose and industry standards. However, common dimensions for steel coils include a width ranging from 600mm to 2000mm, a coil diameter of around 1000mm to 2000mm, and a weight capacity ranging from a few tons to several dozen tons.
- Q: Will a 8mm steel ball fired from a 150lbs crossbow kill small game and if so, from how many yards?
- Steel Crossbow
- Q: Can steel coils be used in the production of HVAC systems?
- Certainly, HVAC systems can make use of steel coils. In the production of HVAC equipment, like air handlers, condenser coils, evaporator coils, and heat exchangers, steel coils are frequently employed. Their durability and strength make them well-suited to endure the rigorous pressures and temperatures involved in HVAC operations. Moreover, steel coils possess favorable heat transfer properties, facilitating efficient heat exchange between the refrigerant and the conditioned air. In summary, steel coils are an dependable and widely-utilized element in the manufacturing of HVAC systems.
- Q: hi i was doing a little history project on guns. i was just wondering if anyone could help me find out what material was used before steel and why this material wasnt as good as steel ( its faults)thanks for your help
- The most common was bronze, which was the strongest material that could be cast, at least until the industrial revolution. Until that time, furnaces which could reach temperatures hot enough to melt steel did not exist. The only way to work with steel would have been forging, which means hammering it into shape while red-rot. Obviously, this is not a very practical method for making large thick-walled cannons (though it was done on occasion. Small arms such as pistols and muskets could be easily made of steel by hand forging.) The most practical way to make cannons was pouring molten bronze which melts at significantly lower temperature than steel. Cast iron was also used. Note that Cast Iron contains 3%-7% carbon, compared to steel which only contains between 2% to 0.2% carbon. Due to the excessive carbon content of cast iron, it's melting point is about 500 degrees lower than steel enabling it to be melted with pre-industrial furnaces. Unfortunately, cast iron is also brittle, unlike steel or bronze. This means that a defective or cracked casting could easily explode, sending iron shrapnel everywhere. (Also, maiming and killing the gun crew, an experienced gun crew was as valuable as the cannon itself!) For this reason. Cast iron cannon were usually considered a cheap, risky alternative to expensive but durable bronze.
