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 is the role of steel coils in the oil and gas industry?
- The oil and gas industry heavily relies on steel coils, which have a crucial role to play. These coils are primarily utilized for the transportation and storage of oil and gas products. Typically, they are crafted from high-quality steel and designed to endure the harsh conditions encountered during the extraction, processing, and distribution of oil and gas. One of the key functions of steel coils in this industry is to serve as containers for transportation purposes. Oil and gas are frequently transported over long distances, either through pipelines or tankers. Steel coils are used in the construction of these pipelines and storage tanks, providing a robust and secure means of transporting these valuable resources. The strength of steel ensures that the pipelines and storage facilities can withstand the pressure and temperature fluctuations that occur during transportation. Steel coils also play an essential role in the production of drilling equipment. The drilling process involves extracting oil and gas from deep underground reservoirs. Steel coils are employed in the manufacturing of various components of drilling rigs, including pipes, casings, and wellheads. These components must be capable of withstanding the high pressures and temperatures encountered during drilling operations. Steel coils offer the necessary strength and durability to ensure the reliability and safety of drilling equipment. Additionally, steel coils are utilized in the construction of offshore platforms, which are bases for drilling operations in offshore oilfields. The severe marine environment, characterized by saltwater exposure and strong winds, demands materials that can resist corrosion and provide structural integrity. Steel coils are used to fabricate the structural components of these offshore platforms, ensuring their ability to withstand the challenging offshore conditions. In conclusion, steel coils are indispensable in the oil and gas industry. They are employed for the transportation and storage of oil and gas products, the construction of pipelines and storage tanks, the manufacturing of drilling equipment, and the fabrication of offshore platforms. The strength, durability, and resistance to harsh conditions make steel coils an essential material in this industry.
- Q:How are steel coils used in the production of steel chains?
- Steel coils are used in the production of steel chains as the raw material. These coils are fed into a machine called a chain-making machine, which shapes and cuts the steel into individual links. The links are then connected together to form the chain, creating a strong and durable product.
- 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:How are steel coils used in the production of oil and gas equipment?
- Steel coils are used in the production of oil and gas equipment as they are typically shaped and welded to create various components such as pipes, tanks, and pressure vessels. These coils provide a strong and durable foundation for the equipment, ensuring it can withstand the harsh conditions and high pressures associated with oil and gas extraction and processing.
- Q:What are the current trends in the steel coil industry?

- Q:How are steel coils inspected for damage during transportation?
- Steel coils are typically inspected for damage during transportation through visual inspections, where trained personnel carefully examine the coils for any visible signs of dents, scratches, or other forms of physical damage. Additionally, specialized equipment such as ultrasonic testing or magnetic particle inspection may be used to identify any hidden or internal defects in the coils. These inspection methods ensure that any potential damage is detected early on, allowing for prompt repairs or necessary precautions to minimize any further harm.
- Q:How are steel coils inspected for weldability?
- A series of comprehensive tests and examinations are carried out to inspect the weldability of steel coils. The main objective of this inspection is to assess the quality and suitability of the steel coils for welding purposes. To begin with, a visual inspection is conducted to identify any visual defects or irregularities present on the surface of the coils. This includes checking for factors such as surface roughness, cracks, scratches, or any other imperfections that might affect the weldability. Following this, destructive testing methods, such as tensile testing and impact testing, are performed. Tensile testing measures the strength and ductility of the steel, ensuring that it meets the required mechanical properties for welding. Impact testing evaluates the steel's ability to resist brittle fracture, which is crucial in determining its weldability. In addition, non-destructive testing techniques like ultrasonic testing (UT) and magnetic particle inspection (MPI) are employed to detect any internal defects or discontinuities. UT utilizes high-frequency sound waves to identify hidden flaws within the steel, while MPI uses magnetic particles to identify defects on or near the surface. Moreover, chemical analysis is carried out to determine the composition of the steel and ensure that it meets the required specifications for welding. This analysis involves checking the levels of carbon, manganese, sulfur, and other elements that may impact the weldability and overall performance of the steel. Furthermore, weldability testing is performed to evaluate how the steel responds to welding processes. This involves conducting various welding trials using different techniques and parameters to assess the steel's behavior during welding, including its susceptibility to cracking, distortion, or other welding-related issues. In conclusion, the inspection of steel coils for weldability is a comprehensive process that involves visual inspection, destructive testing, non-destructive testing, chemical analysis, and weldability testing. Through these thorough inspections, manufacturers can ensure that the steel coils meet the required standards and are suitable for welding applications.
- Q:During fatigue testing of any material (especially for steels), why is strain-control mode preferred over stress control mode?
- because metals, like steel, are ductile and will stretch before breaking. Straining the metal is stretching it, stressing the metal is applying a shearing force or bending until there is an actual metal failure. A sheet metal strap 1inch across and 24 gauge metal is commonly used to support metal ducting systems in construction. These have an average strain to failure weight load as high as 16,200 lbs. As reported by the smacna index, they will safely hold 6800 pounds. Of more interest is the screws used to hold the strap to the duct. While they are grade 3, fairly strong, they strain to 1400 pounds when properly installed, and are safely able to support 650 pounds, unless they are overtorqued (stripped) and this quickly drops to 400 pounds and 125 pounds...big difference.
- Q:I know some .50 Cal BMG will do that, but what are some other cartridges ?Also, are all steel plate the same hardness ?
- Steel plate and steel plate armour are two different grades of steel, and normally nearly anything will go through steel plate. Chetak
- Q:What are the dimensions and weight range of steel coils?
- The dimensions and weight range of steel coils can vary depending on the specific application and industry. However, typical dimensions range from 0.15mm to 3.5mm in thickness, and from 600mm to 2,000mm in width. As for weight, steel coils can range from a few hundred kilograms to several tonnes, depending on the size and type of coil.
