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 protected during transportation?
- Steel coils are kept safe and free from harm during transport through a range of precautionary measures. One widely used technique involves utilizing top-notch packaging materials like heavy-duty plastic wrap or waterproof paper. These materials form a protective shield against external factors such as moisture, dust, and debris. Moreover, steel coils are typically placed on wooden pallets or skids to elevate them from the ground and prevent direct contact with surfaces that may cause scratches or dents. To provide further protection, the coils are securely fastened to the pallets using strong, corrosion-resistant metal strapping or bands. This ensures that the coils remain in position and do not shift or move during transport, significantly reducing the risk of damage. Additionally, specialized equipment like coil cradles, coil racks, or coil bunks are used to load and secure the steel coils onto flatbed trailers or shipping containers. These devices are specifically designed to firmly hold the coils in place and evenly distribute their weight, preventing any stress or strain during transit. Apart from physical safeguards, steel coils may also undergo various surface treatments before being transported to prevent corrosion. This may involve applying a protective coating or oiling the coils to create a barrier between the steel and the surrounding environment. This process is particularly important when the coils are exposed to adverse weather conditions or long shipping durations, as it helps to prevent rust or other forms of corrosion. In conclusion, a combination of appropriate packaging, secure fastening, and proper loading techniques are employed to ensure the safety of steel coils during transportation. These measures guarantee that the coils arrive at their destination without significant damage.
- Q:I'm assuming that brass is flexible, expands and then bounces back to it's original shape. But if aluminum and steel expand and don't contract wouldn't they cause guns to jam more often for example?
- Reloading Aluminum Cases
- Q:Specifically, for the main support beam found in a basement.
- Glulam. Cheaper to buy, cheaper to install. Takes up less space than an I-beam.
- Q:What is the process of pickling and oiling steel coils?
- The process of pickling and oiling steel coils involves several steps to ensure the quality and protection of the steel. Firstly, pickling is the process of removing impurities and scale from the surface of the steel coil. This is typically done by immersing the coil in an acid bath, such as hydrochloric acid or sulfuric acid, which helps to dissolve any oxides, rust, or other contaminants present on the surface. This step is crucial as it prepares the steel for further processing and prevents any potential defects or corrosion. After pickling, the steel coils are rinsed with water to remove any residual acid and then dried. Once the coils are clean and dry, they are then coated with a layer of oil to provide temporary corrosion protection and lubrication during subsequent handling and transport. The oil coating helps to prevent the steel from rusting or oxidizing before it is further processed or used in various applications. The oiling process can be done in several ways. One common method is by applying the oil using a roller or brush, ensuring that the entire surface of the coil is evenly coated. Alternatively, the coils can be passed through a bath or spray chamber where the oil is applied. The type of oil used can vary depending on the specific requirements of the steel and its intended use. Some common oils include mineral oil, synthetic oils, or specialized rust-preventive coatings. Once the oiling process is complete, the steel coils are typically stacked, wrapped, or packaged for storage or transportation. It is important to handle the coils carefully to avoid damaging the oil coating and compromising the corrosion protection. Overall, pickling and oiling steel coils are essential steps in the steel manufacturing process to ensure the quality, cleanliness, and protection of the steel, ultimately extending its lifespan and enhancing its performance in various applications.
- Q:I'm kind of confused as to how the difference between a stainless steel and blued steel firearm is sometimes only $20 or so. Isn't stainless steel fairly more expensive to manufacture than plain carbon steel? Are some stainless steel firearms simply stainless steel finished with carbon steel underneath?
- Stainless guns are made out of stainless steel. Now there are also guns that are coated in nickel. Those are made of the usual gun steel. Stainless steel isn't really that much more expensive than normal steel when bought in large quanities.
- Q:What are the different types of steel coil storage racks?
- There are several types of steel coil storage racks, including coil cradles, coil saddles, coil c-hooks, and coil racks with dividers.
- Q:What is the maximum weight capacity for a steel coil lifting device?
- The maximum weight capacity for a steel coil lifting device can vary depending on the specific design and model. However, these lifting devices are typically designed to handle heavy loads and can have weight capacities ranging from a few tons to over 100 tons. It is important to consult the manufacturer's specifications or guidelines to determine the exact maximum weight capacity for a particular steel coil lifting device.
- Q:i mean cor ten steel( rusted)
- Bill summed it up pretty quick and provided a link. For some reason you are focusing on the copper content when it really is insignificant in the overall picture of the sun hitting its surface. If you could elaborate more, maybe we could offer a better answer.
- Q:Are steel coils affected by temperature changes?
- Yes, steel coils are affected by temperature changes. Steel is a metallic material that expands when heated and contracts when cooled. Temperature fluctuations can cause steel coils to expand or contract, which may impact their dimensions, mechanical properties, and overall performance. It is important to consider and manage temperature changes to ensure the proper functioning and durability of steel coils.
- Q:I am trying to make a homemade fender eliminator for my motorcycle and the instructions from the site I found said to use 22 gage weld steel. I went to lowes and all they had was 26 gage sheet metal. What is the difference between the two? Is weld steel less flexible?
- Gauge is a measure of thickness. 19 Ga = 0.0418 20 Ga = 0.0359 22 Ga = 0.0299 Higher numbers are obviously thinner sheets. To my knowledge the way it works is going up five gauges means the thickness is reduced by half. For example 10 Ga. is 0.1345 in, while 15 Ga is 0.0673 in.
