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: How are steel coils inspected for mechanical properties?
- Steel coils are inspected for mechanical properties through a combination of destructive and non-destructive testing methods. Destructive methods involve conducting tensile, hardness, and impact tests on samples taken from the coils. Non-destructive methods, such as ultrasonic or magnetic particle testing, are also employed to detect surface and internal defects without damaging the coils. These inspections ensure that the steel coils meet the required mechanical specifications for their intended applications.
- Q: What are the pros with stainless steel? You don't have to oil them as much or you don't have to oil them at all?Is the rifling in the barrel typically stainless steel as well? if so, is this better accuracy or does the rifling last longer then conventional?are they worth the extra money?Thanks for any info you can provide!
- stainless steel is a alloyed steel that resist rust and corrosion. show it enough salt (sea spray or sweat) and it will pit Stainless steel goes all the way through ...it's not a coating like nickle-plate. the inside of a stainless barrel is stainless and they hold up just as well as carbon steel barrels. Extra money? Stainless is pretty popular in new production and the price is not that much different than comparable guns in blue. Oil OK... they do hold up better to salt and sweat than bluing...and there is not coating or plating that can wear off. Down side... the reflect light. Some can be a bit to shiny for some situations.
- Q: Are steel coils used in the packaging industry?
- Yes, steel coils are commonly used in the packaging industry for various applications such as strapping, bundling, and securing heavy loads.
- Q: I thought it was STAINLESS STEEL! I have stainless steel can openers spatulas that are rusty. What's up with that? did you know that braces on people's teeth are made of stainless steel? That's why they call people metal-mouth. I used to have braces.
- Stainless steel is manufactured in a variety of different alloys. The percent of Chrome and other metals determine which alloy of stainless is produced. Not all versions of stainless is rust proof, just rust resistant. Not knowing which version of stainless steel you are discussing makes an exact answer difficult. Most stainless steel needs also be exposed to oxygen to retain it's 'stainless' properties. There are also version of steel, Monel and Inconel, that most would consider 'stainless'. Salt water will rapidly affect most versions of stainless with what is called cloride stress corrosion which cause a failure of the lattice structure of the metal. Generally, some stainless steel with a lower chrome content may appear to have discoloration that appears to be rust.
- Q: When steel is cast, does it become weaker/more brittle or anything of this nature? what are the side effects of steel casting on the steel itself?How can you correct these?
- It contains too many air bubble spacing and too many impurity that make it easily to be broken apart. Melt it down again with high heat to remove most impurity, after this process,it becomes iron.
- Q: What are the different coil slitting methods used for steel coils?
- There are several coil slitting methods commonly used for steel coils. These methods are employed to cut larger steel coils into smaller, narrower coils that are suitable for specific applications. 1. Blade Slitting: This is the most common method used for coil slitting. It involves using circular knives or blades to cut the steel coil into narrower strips. The blades are set at predetermined distances and are usually mounted on a rotating shaft. The coil is passed through the blades, and the circular motion of the blades slices through the coil, creating the desired narrower strips. 2. Rotary Shear Slitting: In this method, two sets of rotary shear knives are used to cut the steel coil. The upper and lower sets of knives rotate in opposite directions, creating a scissor-like cutting action. The coil is passed through the shearing blades, and the sharp edges of the knives slice through the coil, producing the desired narrower strips. 3. Sliding Shear Slitting: Sliding shear slitting is another method used for coil slitting. In this method, a stationary upper knife and a moving lower knife are used to cut the coil. The lower knife moves back and forth across the coil, while the upper knife remains stationary. The coil is passed through the moving knife, which cuts it into narrower strips. 4. Crush Slitting: Crush slitting is a less common method used for coil slitting. In this method, the steel coil is passed through a set of rollers equipped with blades. The blades are not sharp, but the pressure exerted by the rollers crushes and fractures the coil, creating the desired narrower strips. 5. Laser Slitting: Laser slitting is a modern and precise method used for coil slitting. It involves using a laser beam to cut through the steel coil. The laser beam is directed onto the coil, and its high intensity melts and vaporizes the steel, creating a narrow slit. Laser slitting offers high accuracy and a clean cut, making it suitable for specialized applications. Each of these coil slitting methods has its advantages and limitations, and the choice of method depends on factors such as the type of steel, desired strip width, production volume, and required precision. Manufacturers select the most appropriate method based on their specific requirements and the properties of the steel coils they are processing.
