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

- Q: This problem has puzzled me for a long time i always think about why stranded people on islands cant make a proper civilization and i always think it comes down to the ability to work metal. But its not like they could make a steel smelter/furnace out of sand...they would need an older one to use to make the new one...where the hell did the first one come from then????
- originally steel was made by hand- by hammering an iron ingot (easily obtained from turf iron), heating it in coal (allows the carbon to penetrate the iron) then folding it and hammering it again- several hundred times. with each such procedure the iron absorbs more carbon and becomes steel of course steel smelters made this process simpler- but then you can't get damascene steel out of a smelter... the island civilisations could make smelters out of clay. But finding clay or iron ore on a coral island would be a forlorn task
- Q: What are the different types of welding used for steel coils?
- Steel coil fabrication involves the utilization of various welding techniques, each catered to specific requirements and applications. Here, we present some commonly employed welding methods for steel coil fabrication: 1. Stick welding, also known as Shielded Metal Arc Welding (SMAW), utilizes a flux-coated electrode and an electric current to generate an arc between the electrode and the base material. SMAW is a versatile and extensively used technique suitable for a range of steel coil applications. 2. Gas Metal Arc Welding (GMAW), also referred to as MIG (Metal Inert Gas) welding, employs a continuous wire electrode and a shielding gas to safeguard the weld pool against atmospheric contamination. GMAW is renowned for its high welding speed and ease of automation, making it a favored choice for steel coil manufacturing. 3. Flux-Cored Arc Welding (FCAW) shares similarities with GMAW, but employs a tubular electrode with flux inside. The flux serves as both the shielding gas and added alloying elements, resulting in enhanced efficiency and weld quality. FCAW is often employed for high-speed welding applications in steel coil fabrication. 4. Gas Tungsten Arc Welding (GTAW), also known as TIG (Tungsten Inert Gas) welding, employs a non-consumable tungsten electrode and an inert gas, typically argon, to protect the weld area. GTAW delivers high-quality, precise welds with exceptional control over heat input, rendering it suitable for thin steel coil materials and critical welding scenarios. 5. Submerged Arc Welding (SAW) involves the use of a continuously fed wire electrode and a granular flux that covers the weld area. The arc is submerged beneath the flux, providing excellent protection and minimizing the need for post-weld cleaning. SAW is commonly employed for welding thick steel coils due to its high deposition rates and deep penetration capabilities. These examples highlight the diverse range of welding techniques employed in steel coil fabrication. The selection of the appropriate welding method depends on factors such as the specific steel grade, thickness, desired weld quality, production speed, and cost considerations. It is crucial to choose the suitable welding technique to ensure the longevity and performance of steel coils across different applications.
- Q: This question is directed to anyone who has played or know someone who plays a lap or pedal steel guitar.I've been a guitarist for about 8 years now and have played a variety of styles from rock, fingerstyle/classical, singer/songwriter acoustic stuff, ect, and now I've really had an interest in learning how to play a lap steel or pedal steel guitar. I am completely new to the instrument(s), so I'm seeking all the information I can. I do know that a pedal steel is a lot more expensive, so I'm probably looking to start on a lap steel for now. Basically how should I get started? Should I find a cheap lap steel at a pawn shop or purchase something new? Are there any good method books out there? I'm a pretty experienced guitarist, so should I expect to get the hang of it quickly? Is there much of a market for a lap/pedal steel player? haha.Also, I am left handed. How much trouble would it be to re-string a steel guitar? Or would I be better off getting a left-handed model?
- Hello okorder / I'm not familiar with the brand...it's certainly not commonly played....but it has the features you need for a starter guitar.
- Q: How are steel coils inspected for elongation using elongation testers?
- Steel coils are inspected for elongation using elongation testers by first selecting a representative sample from the coil. This sample is then mounted onto the tester, which applies a controlled force to stretch the steel. The elongation tester measures the change in length of the sample as it is stretched, allowing the calculation of the elongation percentage. This data is crucial for evaluating the steel's ductility and mechanical properties, ensuring it meets quality standards and can withstand various applications.
- Q: i have a computer chair where the metal part that attachs the top part to the bottom with wheels has cracked around half of the assembly. my dad said it might be able to be repaired with jb weld. can jb weld fix it? how strong is jb weld? is it as strong as steel?
- the stuff is pretty strong... i have a friend who blew a hole in his crankcase of his 07 cr450f and used jb weld on it... added oil and rode on it.. the stuff is crazy strong just give it a day to dry
- Q: which is the most tough and durable steel type ??
- C'mon. Really? That's your question? How about some actual details like the application, is it going to be formed into a shape, do you need to weld it, what type of environment like corrosion and temperature is it going to be subject to? There are roughly 2,000 grades of steel and a couple hundred grades of stainless steel. Steels can be soft or they can be exceptionally hard. We need more info please.
- Q: How are steel coils processed before being used in manufacturing?
- Steel coils undergo several processing steps before they are used in manufacturing. The first step is to uncoil the steel coil, which involves unwinding it from a large spool. This is usually done using a machine called a decoiler. Once the coil is uncoiled, it is inspected for any defects or damages. After inspection, the steel coil goes through a process called leveling. This process involves passing the coil through a series of rollers to remove any unevenness or waviness in the steel. Leveling ensures that the coil has a uniform thickness and flat surface, which is crucial for further processing. The next step is to clean the steel coil to remove any impurities, such as rust, oil, or dirt. This is usually done by running the coil through a cleaning line, where it is treated with chemicals and water sprays. The cleaning process ensures that the surface of the coil is free from contaminants, which can affect the quality of the final product. Once the coil is cleaned, it may undergo additional processes depending on the specific requirements of the manufacturing process. For example, the coil may be annealed to improve its ductility and reduce its hardness. Annealing involves heating the coil to a specific temperature and then slowly cooling it. This process helps to relieve internal stresses and improve the steel's mechanical properties. After all the necessary processing steps are completed, the steel coil is ready to be used in manufacturing. It can be further processed into various shapes and forms, such as sheets, plates, or strips, depending on the specific requirements of the manufacturing process. These processed steel coils are then used in a wide range of industries, including automotive, construction, appliances, and machinery.
- Q: Can steel coils be painted or coated?
- Yes, steel coils can be painted or coated. Painting or coating steel coils is a common practice to enhance their aesthetic appearance, protect them from corrosion, or improve their performance in various applications.
