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: ive made lots of knives but they are dark and not shiny. how do i polish a knife and make it shiny
- Look for buffing compound at the hardware store. Home depot lowe's od even Wal-mart/ There is a compound for steel and for iron. I t will not make iron real shinny but it will make it look good. This stuff is to be used with a buffing wheel but I have used it on rags and it work great.
- Q: hey therejust wondering about changing nylon strings to steel strings...i have an acoustic guitar and it has nylon strings, but i was thinking about switching to steel strings, as i think it sounds better.this might sound really stupid... but is that possible? i mean they call it a steel stringed GUITAR and nylon stringed GUITAR, so if i wanted to switch would i have to get a whole new guitar? please help, im reaaally confused!thanks
- You'd have to get a new guitar if you want to use steel strings. If you put steel strings on a nylon stringed guitar, you could snap the neck right off of the guitar. Steel strings have more tension than nylon strings. You can't try the other way around either, since nylon strings simply won't fit on a steel-stringed guitar.
- Q: I just got my Daewoo K2 in 5.56 and i know they are tough and reliable but how well will it fair with steel rounds. I know shooting brass is better for any gun but what kind of extra wear and tear would i be looking at with shooting steel. Also what about reloading steel. Is it recomended. I would not even be asking this but steel is far cheaper than brass ammo, and i need to save some money.
- You can't reload steel cases. I don't really know, but you just can't. If a mild steel case is harder than the chamber and bolt of your firearm, you should have got a better firearm.
- Q: How are steel coils measured for thickness?
- Steel coils are measured for thickness using a variety of methods. One common method is using a micrometer, which is a precision measuring instrument that accurately determines the thickness of the coil. The micrometer is gently pressed against the surface of the coil and the measurement is taken. Another method involves using a thickness gauge, which is a handheld device that can quickly and accurately measure the thickness of the steel coil. The gauge is placed on the coil's surface and the thickness is displayed on a digital screen. In some cases, ultrasonic thickness testing is used to measure the thickness of steel coils. This method involves using ultrasonic waves that are emitted from a handheld device. The waves travel through the coil and bounce back to the device, providing an accurate measurement of the thickness. Regardless of the method used, it is important to ensure that the measurements are taken at multiple points across the coil to account for any variations in thickness. This ensures that accurate and reliable measurements are obtained.
- Q: How are steel coils used in the production of fireproof doors?
- Steel coils are used in the production of fireproof doors as they serve as the core material for the door's structure, providing strength and durability.

- Q: I'm getting my nose pierced, meaning that i have to keep the piercing in for a prolonged time. i've always had reactions when wearing sterling silver or fake earrings (i dont know what types of metal they were) after wearing it overnight. Will I get a reaction on my nose piercing if the stud is surgical steel?
- The chances of a reaction from the stud is minimal. Surgical steel is an alloy specifically designed to make sterile safe surgical equipment. Often made with titanium or nickel, surgical steel is highly reactive and forms an oxidized layer when made. This layer creates a stable surface. The titanium and nickel are both very hard and resistant to scratches which make for easy sterilization. This will help keep your piercing clean. Be sure to follow the directions you receive when you get your piercing and keep it clean.
- Q: We all know that when we drop a small steel ball (size 3mm diameter; weight 1.10 grams) and a paper (size 11.7 inches length and 8.3 inches breadth; weight 4.5 grams) from a height. The steel ball will win the race to the ground due to its aerodynamic structure.Now imagine the same steel ball with the same weight converted to the structure similar that of paper. What will be the result? Which object will fall first; steel sheet or paper?
- In okorder /... 11.7x8.3 inch paper 97.11 square inches 0.062651488 sq meters at 4.5gm is a non-standard 19 pound bond ledger paper, but that is OK, because at least it is in range. 38 gauge steel sheets are about the thinnest that hold their structure 0.00625 thick 1221 g/m? or, at 11.7x8.3 76.5grams So, with this data at hand we can better visualize the situation. Paper of 0.00625 thick in the size shown is 35# paper 131.68 g/m? 8.25grams Steel is higher in density than paper, so you cannot get the same size and air flow without it being lighter in weight than the steel and the air resistance would be lower for the heavier item, so steel of the same shape and thickness as paper falls faster. Suppose you want paper heavier than steel for the same area, then the thickness increases. Will a steel sheet 0.00625 thick and 11.7x8.3 inch size 76.5gm fall faster or slower than a 9 or 10 times thicker paper sheet? If it was able to hold flat in each type the thicker paper should get more backflow behind it aerodynamically and fall faster than an equal weight thinner steel sheet as my guess, but I don't have those numbers. The steel will always be heavier than the paper for the same exact shape and thickness by about 9x. My answer here is difficult, but the question has some flaws to think about.
- Q: What are the different methods of coil flattening for steel coils?
- Coil flattening for steel coils can be achieved through various methods, each having its own advantages and limitations. Some commonly employed techniques are as follows: 1. Roller leveling: By passing the steel coil through a series of rollers that exert pressure, this method flattens the coil. The rollers can be adjusted to achieve the desired level of flatness. Roller leveling is a versatile approach capable of handling a wide range of coil sizes and thicknesses. 2. Precision leveling: This method employs a more advanced leveling machine that applies pressure to specific areas of the coil to eliminate any waviness or defects. Precision leveling is commonly used for high-quality steel coils that require exceptionally flat surfaces. 3. Stretch leveling: Also known as tension leveling, this technique involves stretching the steel coil beyond its yield point, causing permanent deformation and flattening. Stretch leveling is frequently used for thinner gauge coils and effectively eliminates coil set and crossbow defects. 4. Temper rolling: This method subjects the steel coil to a controlled low-temperature heat treatment followed by cold rolling. The combination of heat and cold rolling helps relieve internal stresses and improve flatness. Temper rolling is particularly suitable for coils that require enhanced surface quality. 5. Laser flattening: This advanced method utilizes laser technology to selectively heat and flatten specific areas of the coil. Laser flattening is highly precise and capable of correcting localized defects or unevenness. However, due to its higher cost, it is typically used for smaller coils. It is essential to consider various factors, such as desired flatness requirements, coil dimensions, material properties, and production budget, when selecting the most appropriate coil flattening method.
