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:hey... i don't need to change my strings, but i found a set of Bronze acoustic guitar strings by pure tone... i have a few questions on them:can i put them on a steel string guitar? i know i can't put nylon strings on... but i don't see why i can't put bronzethey are light gauze... i have no idea what my current gauze is, but i play in Dropped D tuning... so would the E/D string (6th) be too loose? finally, can you get strings designed to be played in Drop D?any help is apprechiated :D
- Are you talking about a steel guitar or a steel string guitar. Bronze strings won't work properly on a steel/lap steel/electric guitar but hey are designed to be played on an acoustic or acoustic electric steel string guitar. Light gauge strings are OK. However, the low E may be too thin if you tune that down to D. Another thing to consider is that the neck truss rod probably needs to be adjusted slightly if you change string gauge. This procedure is fast and simple if you know what you're doing. You should however leave it to someone else if you don't know how it's done. If you play all the time in drop D, I would probably use a set of medium strings or have a light set and use a heavier low E-string. Personally, I use drop D on my acoustics from time to time. I use light strings and find this to work well for me.
- Q:I live in the Black Hills and I need to re-side my cottage. I like the look of vinyl. I've heard pros and cons about both steel and vinyl. Is steel really that easy to dent? It just doesn't look as 'clean' as vinyl. Also what 3 color combos do you like? My cottage has shutters.
- I have steel siding, and it is a pain in the butt. It's much harder to keep clean than vinyl. As for color combos, I love mine, sunny yellow with off white trim, and brick red for the doors. I added new brushed chrome doorknobs and brushed chrome rails around the porch, and it looks awesome. I am planning to have the steel siding replaced with vinyl though.
- Q:What are the different methods of skin pass rolling for steel coils?
- Steel coils can undergo skin pass rolling using various methods, each possessing its own distinctive characteristics and advantages. Some commonly employed techniques include: 1. Dry Skin Pass: This method entails passing the steel coil through rolls without applying any lubricant or coolant. The absence of these substances aids in enhancing the steel's surface finish by minimizing thickness fluctuations and achieving a smoother texture. 2. Wet Skin Pass: This approach involves utilizing a water-based emulsion or coolant during the skin pass rolling procedure. The coolant serves to decrease friction and heat generated during rolling, resulting in improved surface quality and reduced risk of surface defects. 3. Electrolytic Skin Pass: This technique utilizes an electrolytic solution during skin pass rolling. The steel coil is submerged in the solution, and an electric current is applied to the coil, leading to controlled surface etching. This method is particularly effective in improving surface cleanliness and eliminating oxide scale. 4. Temper Mill Skin Pass: This method combines skin pass rolling with a tempering process. The steel coil undergoes a series of rolls, followed by a heating and cooling process to achieve the desired mechanical properties and surface finish. This method is commonly employed for high-strength and automotive-grade steel coils. 5. Tension Leveling: In this method, the steel coil is passed through a series of rolls while under high tension. This elongates the steel, reducing residual stresses and shape defects, thereby enhancing flatness and dimensional stability. It is important to note that the selection of a skin pass rolling method depends on factors such as the desired surface finish, required mechanical properties, and the type of steel being processed. Each method offers its own advantages and limitations, and manufacturers typically choose the most suitable approach based on their specific needs.
- Q:basically a builder told us steel is good but when we got MFI, BQ they only have acrylic
- I okorder . There are so many articles on this site that talk about all of the bathtubs available today. If you're wondering about what kind of material is best for a bathtub, this site will definitely help!
- Q:Can steel coils be bent or shaped?
- Yes, steel coils can be bent or shaped. Steel coils are highly flexible and can undergo various bending and shaping processes to achieve desired forms and configurations.
- Q:I want to buy a VERY sturdy bunkbed, but don't know which one would be better with not getting loose or falling apart.
- Metal/Steel, tighten it down and put some washers in between the steel and the screw so it creates a tight fit and movement wont affect the screw directly.
- Q:What is the standard width of steel coils?
- The standard width of steel coils can vary depending on the specific industry and application. However, in general, the standard width for steel coils ranges between 36 inches to 72 inches. The specific width will depend on factors such as the type of steel being used, the intended use of the coils, and the equipment used for processing and handling the coils. It is important to consult industry standards and specifications to determine the appropriate width for a particular steel coil application.
- Q:What is the difference between carbon steel and spring steel?? And which is the better one to make swords with??
- All steel has carbon in it. If too much carbon is in the steel it is extremely hard and brittle. Like cast iron. The only difference between iron and steel is the level of carbon. Cast iron is very hard. A drill can barely drill thru it unless you treat it with something like cobalt or titanium nitride. But if you hit cast iron with a hammer very sharply it will break into pieces from the shock. Too low of carbon causes problems though. Steel is very flexible and machinable when it has very low carbon, but it also doesn't wear very well. If you made a sword out of low carbon steel, it would bend very easily and the edge would get dull quick. If you bent it, it wouldn't spring back either. That gets us to spring steel. This is just the right amount of carbon so the steel is very hard and the sword can hold an edge. It also gives it shock resistance. You can bend the sword and it returns to it's original shape. That is why it is called spring steel. The steel resists bending and when it does bend, as long as it isn't to far, it springs back when let go, to it's original shape
- Q:What are the common methods of welding steel coils?
- The common methods of welding steel coils include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), flux-cored arc welding (FCAW), and submerged arc welding (SAW).
- Q:What could the impurities in steel wool be?And why are they there?Thanks for your help :)
- Impurities in steel wool would be of the elemental type. I'm sure steel wool is a mixture of different low grade not good for much of anything else materials. There may be excessive impurities such as lead, cobalt, boron, aluminum etc... in the steel wool. There may also be solvent residue on the wool i.e cleaner, lubricant etc.. I'm sure every batch is different - I know the iron level is high thats what makes them rust quickly.
