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 used in the production of conveyor systems?
- Steel coils are used in the production of conveyor systems as they are formed into various components such as conveyor belts, pulleys, and rollers. These components provide strength, durability, and flexibility to the conveyor system, ensuring smooth movement of materials along the conveyor and enhancing its overall performance.
- Q: also what are the factors of location of these steel plants
- iron ore comes from mines in North America, but also abroad. I think the majority of ore comes from mines in Michigan, Minnesota, and Canada. reason that steel plants are near great lakes is because the car industry is there... they are the major consumer of steel...
- Q: How are steel coils used in the manufacturing of automotive parts?
- Steel coils are used in the manufacturing of automotive parts as they provide a versatile and cost-effective material for producing various components. These coils are first processed and shaped into specific forms, such as sheets or strips, which are then further worked on to create parts like body panels, chassis, and suspension components. The high strength and durability of steel make it suitable for ensuring the structural integrity and safety of automobiles, while its malleability allows for easy forming and welding processes.
- Q: Can't find it- this is for a physics experiment for youngs modulus done with a steel wire.
- It depends on the type of steel and how the wire was made (e.g. whether it was drawn hot or cold, whether it was heat treated after it was drawn, etc). For mild steel the elastic limit is about 400 MPa. Note this is not the same as the breaking stress for the wire which will typically be significantly higher for a ductile material like steel. If you want to measure a stress-strain curve to find youngs modulus, make sure you measure several points at stresses below the elastic limit - for example try increasing the stress in increments of about 50 MPa.
- Q: What are the factors influencing the price of steel coils?
- The price of steel coils can be influenced by a variety of factors. These factors include: 1. Raw material costs: The cost of raw materials, such as iron ore and coal, directly affects the price of steel coils. Fluctuations in commodity prices can have a significant impact on the overall price. 2. Supply and demand: The balance between supply and demand in the steel industry plays a crucial role in determining the price of steel coils. If there is high demand, prices are likely to increase. Conversely, if there is an oversupply, prices may decrease. 3. Production and manufacturing costs: The cost of producing and manufacturing steel coils, including labor, energy, and transportation costs, can also impact the final price. Any changes in these costs can influence the overall price. 4. Currency exchange rates: The price of steel coils can be affected by fluctuations in currency exchange rates. If the currency in which steel is traded weakens against other currencies, it can result in higher prices. 5. Government regulations and policies: Government regulations, such as import tariffs, export restrictions, and environmental regulations, can impact the price of steel coils. These regulations can affect the cost of production and trade, ultimately influencing the price. 6. Market competition: The level of competition among steel manufacturers and suppliers can also impact the price of steel coils. If there are many suppliers and manufacturers, it can lead to competitive pricing and potentially lower prices. Conversely, if there are few suppliers dominating the market, prices may be higher. It is important to consider that these factors can vary over time and in different regions, which ultimately affects the pricing of steel coils in the market.
- Q: my step father bought a big steel drum grill it has steel sheets (very thin) that go inbetween the flame and the food (closer to the flame) with that there the food will not cook, it does not get hot enough????? please help... what should we do
- yes that keeps the fat from dripping on the burners - just try it - it works.
- Q: What are the key factors affecting the strength of a steel coil?
- The key factors affecting the strength of a steel coil include the grade and composition of the steel used, the manufacturing process and techniques employed, as well as the heat treatment and cooling methods implemented. Other factors such as the thickness and width of the coil, as well as any mechanical or surface treatments applied, can also influence its strength.
- Q: Also, what is the top best slow cooker that is 100% stainless steel? Thank you!
- You do not want 100% stainless steel cookware, because it's a poor conductor of heat. All high quality stainless cookware is layered with stainless steel only on the exterior and interior surfaces, while having at least an internal heat spreading core of aluminum or copper. Not all stainless steel is sufficiently ferrous (magnetic) to work with electric inductive cooktops, so some stainless cookware adds an additional layer of ferrous steel in addition to the thermal cores. You also wouldn't want a slow cooker that's 100% stainless steel, because the uneven heating would cause food to burn more quickly. They are usually made of ceramic stoneware for a reason, even heating. Besides, a stainless pressure cooker (with alum/copper) core can in less than an hour everything a slow cooker does in 3+ hours, with better flavor, color, and nutritional content. By the way, the Prestige stainless cookware isn't 100% stainless, of course, and that's a GOOD thing.
- Q: Help please.What atoms are there in steel?Like water is equals to 1 Oxygen atom + 2 Hydrogen atoms.Thnx 4 d help.
- Steel is mostly iron with a small amount (less than 1%) of carbon added. Stainless steel has other metals like chromium and nickel added.
- Q: How are steel coils inspected for quality control purposes?
- Steel coils are inspected for quality control purposes through a combination of visual inspection, dimensional measurements, and various non-destructive testing techniques. This includes checking for surface defects, such as scratches or dents, as well as verifying the dimensions, weight, and shape of the coils. Additionally, technologies like ultrasonic testing, magnetic particle inspection, and X-ray examination are employed to detect internal defects, such as cracks or inclusions, ensuring that the steel coils meet the required quality standards.
