Description of Prepainted Aluminum Zinc Rolled Coil for Roof construction
Aluminum zinc coils 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 Aluminum Zinc Rolled Coil for Roof construction
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 Aluminum Zinc Rolled Coil for Roof construction
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:What is the process of pickling and oiling steel coils?
- To ensure the quality and protection of steel coils, a series of steps are undertaken in the process of pickling and oiling. The first step involves pickling, wherein impurities and scale are removed from the surface of the steel coil. This is achieved by immersing the coil in an acid bath, such as hydrochloric acid or sulfuric acid, which effectively dissolves any oxides, rust, or contaminants present on the surface. This step is critical as it readies the steel for further processing and safeguards against potential defects or corrosion. Following pickling, the steel coils are rinsed with water to eliminate any residual acid and then dried. Once they are clean and dry, a layer of oil is applied to provide temporary corrosion protection and lubrication during subsequent handling and transport. The oil coating acts as a barrier, preventing rusting or oxidation before the steel undergoes further processing or is utilized in various applications. The oiling process can be executed through various methods. One common approach is to apply the oil using a roller or brush, ensuring an even coating across the entire surface of the coil. Alternatively, the coils can be passed through a bath or spray chamber where the oil is administered. The choice of oil depends on the specific requirements of the steel and its intended use, with options ranging from mineral oil and synthetic oils to 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 crucial to handle the coils with care to avoid damaging the oil coating and compromising the corrosion protection it provides. Overall, the pickling and oiling of steel coils are indispensable steps in the steel manufacturing process. They ensure the quality, cleanliness, and protection of the steel, thereby prolonging its lifespan and enhancing its performance in various applications.
- Q:How are steel coils used in the production of steel handles?
- Steel coils are used in the production of steel handles by being processed and shaped into the desired handle design. The coils are uncoiled and fed into a machine where they are cut, bent, and formed to create the handle shape. The coils provide the raw material needed for the manufacturing process, ensuring the handles are strong, durable, and able to withstand the required usage.
- Q:i want a good modern carbon steel (not stainless) knife. trying to keep it under 50$ also nothing to gruesome just a small pocket knife. thank you
- Well, okorder /... They did make other folders in M2 steel, but the thing is those are out of production and the cost is very high. Spyderco made M4 steel folder knives, and so did Benchmade. Although,both are outside of 50$ budget. I guess Opinels are best option.
- Q:I am thinking about getting a cold steel tilite or a kershaw leek or possibly a buck sirus. If you have had any experience with these knives please give it to me. thanks
- You could argue that CS makes the tougher steel, but as was pointed out, none of their wares are made in the U.S. - if that doesn't matter, then go with the CS. I started with a CS Holdout II and ended up sending it back and going with a Kershaw (Ken Onion) Blur for EDC. My next knife will be a Benchmade- they are pricey but everyone I've ever spoken to about EDC knives tell me to go to Benchmade and no one else. Not one to just listen, I had to try out a few myself. Bought the wife a Kershaw Scallion...in purple, no less.
- Q:What are the different surface treatments available for steel coils?
- There are several different surface treatments available for steel coils, including galvanizing, painting, and powder coating. Galvanizing involves applying a layer of zinc to the surface of the steel to provide corrosion resistance. Painting involves applying a layer of paint to the surface to enhance its appearance and protect it from rusting. Powder coating is a process where dry powder is electrostatically applied to the steel surface and then cured under heat to form a protective and decorative coating.
- Q:How are steel coils used in the construction of buildings?
- Steel coils are used in the construction of buildings for various purposes, primarily for structural support. These coils are typically used to create steel frames, beams, and columns that provide strength and stability to the structure. Additionally, steel coils are also used in the production of roofing materials, wall cladding, and reinforcement bars, which further enhance the durability and safety of the building.
- Q:What are the environmental considerations when using steel coils?
- Some of the key environmental considerations when using steel coils include the production process, energy consumption, and the potential for waste generation. Steel production is resource-intensive and can result in high greenhouse gas emissions, contributing to climate change. Energy consumption during manufacturing and transportation should be minimized to reduce carbon footprints. Additionally, proper waste management and recycling practices should be implemented to minimize the environmental impact of steel coil usage.
- Q:I need a machine which can produce steel pipes, but I don't know where to look...If you want me to state dimensions etc. just say...Thanks :)
- Gary, Indiana. There's lots of old, unused steel forming equipment just laying around.
- Q:How are steel coils coated?
- Steel coils are coated using a process called coil coating, where a thin layer of protective material such as paint, plastic, or zinc is applied to the surface of the steel coil. This can be done through various methods including roll coating, spray coating, or electroplating, depending on the desired coating material and application.
- Q:Can steel coils be coated with fluorescent materials?
- Yes, steel coils can be coated with fluorescent materials.
