Description of Aluminum Zinc Rolled Coil
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 Aluminum Zinc Rolled Coil for Construction Roof
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:How are steel coils stored in warehouses?
- Steel coils are typically stored in warehouses by placing them on sturdy racks or shelves, often in a vertical position. This allows for efficient use of space and easy access to the coils for transportation or further processing. Additionally, steel coils are usually separated by wooden or metal spacers to prevent damage from contact with each other.
- Q:How are steel coils inspected for flatness?
- Steel coils are inspected for flatness by using a variety of methods and techniques to ensure they meet the required standards. One common method is through visual inspection, where trained inspectors visually examine the surface of the coil for any signs of waviness or unevenness. They look for any visible defects such as waves, buckles, or twists that may affect the flatness of the coil. Another method used for inspecting flatness is through the use of specialized equipment such as flatness gauges or profilometers. These instruments measure the surface profile of the coil and provide detailed information about any deviations from the desired flatness. They can detect both local and overall flatness issues, allowing for a more accurate assessment of the coil's quality. In addition to visual and instrumental inspections, steel coils can also undergo physical tests to assess their flatness. One such test is the "drape" test, where the coil is draped over a flat surface and any noticeable gaps or unevenness are measured. This test provides a quick and practical way to identify any major flatness issues. Furthermore, computerized analysis and simulation techniques are becoming increasingly popular for inspecting the flatness of steel coils. These methods involve using advanced software to analyze the coil's surface data and generate detailed reports on its flatness characteristics. By comparing the actual surface profile with the desired specifications, these techniques provide a comprehensive assessment of the coil's flatness. Overall, inspecting steel coils for flatness involves a combination of visual inspection, specialized equipment, physical tests, and advanced analysis techniques. These methods ensure that the coils meet the required flatness standards, which is crucial for their successful use in various industries like automotive, construction, and manufacturing.
- Q:I heard that titanium isn't the most hypoallergenic metal because it is treated and the chemicals can cause an allergic reaction. I also heard that surgical steel is the best because it is what is used in surgery and in hip replacement implants etc. Is this correct?I've always heard that titanium is best, but now I'm curious because surgical steel is much cheaper than titanium which can be expensive.Thanks
- Implant grade titanium is much better than surgical steel. The nickel content in it (which is what alot of people are allergic to) is virtually non-existant. Though most people with a nickel allergy are fine with surgical steel too, its too small for most people to react to. But the odd few people do. Its the same with everything. Good surgical steel is probably better than cheap titanium. But implant grade ti will beat it hands down. And ti is alot stronger, and is also used in surgical impants and as replacement bits too. But a big lump of titanium hip is going to be expensive. If you're not allergic to steel, theres little reason for the extra cost, especially if it's likely to outlive you. Niobium has no nickel in at all. But that really is expensive, and I've never seen any threaded. Any particular reason why you ask? ----- Piercing-wise titanium will be better than steel. Unless they carry some not so great ti. You should be fine with steel though.
- Q:What are the common methods of painting steel coils?
- There are several common methods used for painting steel coils, depending on the specific requirements and desired outcomes. Here are some of the most commonly employed methods: 1. Coil coating: This is the most common method used for painting steel coils. It involves applying a layer of paint on the coil's surface before it is shaped into its final form. The coil is first cleaned and pre-treated with chemicals to ensure proper adhesion of the paint. Then, the paint is applied using various techniques such as roll coating, spray coating, or dip coating. The coil is then cured in an oven to ensure proper drying and adhesion of the paint. 2. Electrostatic painting: This method involves using an electrostatic charge to apply the paint onto the steel coil. The coil is first cleaned and pre-treated, and then an electrostatic charge is applied to the paint particles. The charged particles are attracted to the grounded coil, resulting in an even and efficient paint application. This method is often used for high-performance coatings as it provides excellent coverage and adhesion. 3. Powder coating: Powder coating is a popular method for painting steel coils, especially for applications that require a durable and long-lasting finish. In this method, a dry powder paint is applied to the coil's surface electrostatically. The powder adheres to the coil due to the electrostatic charge, and then the coil is heated in an oven to melt and cure the powder, forming a smooth and protective coating. 4. Spray painting: Spray painting is commonly used for smaller steel coils or touch-up applications. It involves using a spray gun to apply the paint onto the coil's surface. The coil is cleaned and pre-treated, and then the paint is sprayed in a controlled and even manner. This method allows for precise control and customization of the paint application. Overall, the choice of painting method depends on factors such as the desired finish, durability requirements, cost considerations, and the specific application of the steel coil. Each method has its own advantages and limitations, and it is important to select the most suitable method based on the specific needs and constraints of the project.

- Q:should I shoot Herters .308 steel cased ammo in my Remington 7400.and why shouldn't I?
- Kudos to NXile for his/her post. Ironically, I recently posted a similar answer in this forum and got many thumbs down. The problem with the non-expansion of steel cased ammo is not limited to the blow-back and soot build-up inside the action. The other problem is that your Remington 7400 was engineered at the Remington factory as a sporting firearm that uses brass cased sporting ammunition. When you switch to the steel cased ammo, the casing doesn't have a chance to grab at the walls of the chamber to slow it down. The result is heavier recoil on the action of the gun. Over time, you will break something. Also, I don't like the idea of steel rubbing against steel inside the chamber area of a gun. I know sure sure I won't use steel cleaning rods or brushes to clean the barrel of a rifle. So why would I want to chance shooting steel cased ammo? The only stuff I will shoot steel cased ammo out of are the junky SKS and AK style rifles that I don't care about. Anything with real value...and I only use brass ammo with non-corrosive priming.
- Q:This needs to be in a percentage by mass. Could you please also reference where this info has come from. Thanks.
- Steel is almost all elemental Iron (Fe) with a small percentage of carbon (about 0.2 percent) and other alloying metals if required. Iron as in cast iron just has more carbon which lowers the melting point to where it can be cast with lower technology (it was discovered first). Bessemer developed a process to remove most of the carbon and increase the furnace heat, resulting in a tougher metal called steel.
- Q:What are the common problems faced during steel coil production?
- During the production of steel coils, several common issues may arise. One of the most frequently encountered problems is the breakage or damage of the coils. This can happen as a result of improper handling or transportation, leading to cracks or fractures. To minimize the risk of coil breakage, it is crucial to adhere to proper handling procedures. Another issue that often arises is coil slippage. This occurs when the coils are not securely stacked or stored, causing them to shift or slide. Coil slippage can cause damage to the coils and potentially lead to accidents or injuries. Therefore, it is essential to have adequate storage systems in place to prevent such slippage. Furthermore, corrosion is a prevalent problem in steel coil production. Corrosion can be caused by exposure to moisture, air, or other corrosive substances. It can result in the deterioration of the steel, reducing its strength and durability. To address this issue, it is necessary to implement effective corrosion prevention measures, such as proper coating or storage techniques. Coil quality issues are another challenge faced in steel coil production. These problems can include inconsistencies in thickness, width, or surface defects on the coils. Various factors, such as improper rolling processes, equipment malfunctions, or material defects, can contribute to these quality problems. Regular quality checks and inspections should be carried out to promptly identify and resolve any issues. Moreover, problems related to coil handling and loading may also arise during steel coil production. Improper lifting or loading techniques can lead to coil damage, resulting in deformations or even accidents. Proper training and education of employees on appropriate handling and loading procedures are crucial to prevent such problems. In conclusion, steel coil production can encounter various challenges, ranging from coil breakage and slippage to corrosion and quality issues. Implementing proper handling, storage, and quality control measures is indispensable in minimizing these problems and ensuring the production of high-quality steel coils.
