Description of Prepainted Galvalume 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 Prepainted Galvalume Rolled Coil
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: Is it possible to have a 25 room Hotel building with Steel structure. Thay is instead of traditional RCC can we have a 25 room hotel constructed using steel construction? Is it economic and how much time will it take to construct the same? Appraximate area would be 5000sq.ft to 10000sqft.
- it is possible...but with the current ever rising cost of steel...it is more expensive than reinforced concrete..... ...one more disadvantage is tat u have to use large I sections for the columns as steel do not take compression as good as concrete... ..tat is why u see..almost all totally steel structures are bridges where tensile strength rules more than compression.
- Q: I saw an amazing flamenco player, however i have a steel string guitar, where he had a nylon stringed one. So i was wndering if its possible to play flamenco songs on the steel string guitar, and where could i find a tab for it? are there tabs for rasegueados?
- Well, you couldn't play traditional flamenco on a steel string guitar, that's for sure. What you could do is learn some flamenco chords and chord progressions. One problem is that a lot of flamenco techniques on a steel string guitar -- rasgueado, for example -- will literally sand your right hand fingernails down to the nub. It's not going to be pretty, and will probably be painful. Even on a flamenco guitar I protect my right hand nails with a thin coat of super glue. Also, the fingerboard of a flamenco guitar is wider than that of a steel string guitar. That's because many of the notes played in flamenco are actually played with the left hand, not the right hand - lots of hammer ons and pull offs. You can do that higher up the neck on an steel string guitar, but it would be hard to do that in first position on that guitar. Anyway, yes, to a small extent you could conceivably do something that has a flamenco sound on a steel string guitar. But why? You can get a great student model flamenco guitar from Yamaha. It's only $350. Then, you need a teacher. Flamenco is difficult to learn (I've been at it for ten years) and it's important to learn from an instructor who can teach you the correct techniques. Otherwise, you just have to learn everything all over again when you finally do take lessons. Intermediate and advanced students can learn from a video, but beginners really need face time with an instructor. Best wishes.
- Q: What are the different methods of testing the mechanical properties of steel coils?
- There are several methods available for testing the mechanical properties of steel coils. These methods are crucial for determining the strength, ductility, and overall quality of the steel. Some of the commonly used methods include: 1. Tensile testing: This method involves applying a tensile force to a steel coil until it fractures. The test measures the maximum stress a material can withstand before breaking, as well as its elongation and reduction in cross-sectional area. Tensile testing provides important information about the ultimate tensile strength, yield strength, and elongation of the steel coil. 2. Hardness testing: Hardness testing determines the resistance of a material to indentation or scratching. Numerous methods are available for measuring the hardness of steel coils, such as Brinell, Vickers, and Rockwell hardness tests. These tests provide an indication of the steel's ability to resist deformation and wear. 3. Bend testing: Bend testing involves subjecting a steel coil to a controlled bending force until it reaches a specified angle or until a crack appears. This test assesses the ductility and flexibility of the steel, as well as its resistance to cracking or fracture under bending stress. 4. Impact testing: Impact testing measures the ability of a steel coil to absorb energy when subjected to a sudden shock or impact. The most commonly used method is the Charpy impact test, where a notched specimen is struck by a pendulum hammer, and the energy absorbed during fracture is measured. This test evaluates the toughness and resistance to brittle fracture of the steel coil. 5. Fatigue testing: Fatigue testing involves subjecting a steel coil to repeated or cyclic loading to simulate the stresses it may encounter during its intended use. This test assesses the steel's resistance to fatigue failure and its ability to withstand repeated stress over an extended period. 6. Ultrasonic testing: Ultrasonic testing utilizes high-frequency sound waves to detect defects or flaws in the steel coil. This non-destructive testing method can identify internal or surface defects, such as cracks, voids, or inclusions, which may affect the mechanical properties of the steel. It is important to note that these testing methods are often performed in accordance with industry standards and specifications, such as ASTM (American Society for Testing and Materials) or ISO (International Organization for Standardization) standards, to ensure accurate and reliable results.
- Q: I am reading the book The Cure For All Advanced Cancers by Hulda Regehr Clark.She writes for example: cancer can be caused by exposure to heavy metals, like nickel and chromium from stainless steel cookware. Stainless steel cookware releases chromium and nickel, two of the most carcinogenic metals.Are there any studies done measuring how much nickel and cadmium can be released from the regular use of stainless steel cookware?Is this a commonly accepted opinion that use of stainless steel cookware is dangerous?If not stainless steel, what kind of cookware to use? I heard that non-stick cookware also releases some harmful chemicals.
- No, the studies done and published in JAMA showed that the over cooking of the food MAY lead to higher incidents of SOME cancers but the cookware did not contribute. Humans do well filtering heavy metals which is why spring water tastes so good to us. This author is wrong if not she'd win a Nobel prize for finding a simple way to prevent cancer.
- Q: What is the minimum diameter of a steel coil?
- The minimum diameter of a steel coil depends on various factors such as the thickness of the steel, the type of coil, and the intended use. However, it is generally recommended to have a minimum diameter of around 3 times the thickness of the steel for optimal performance and to prevent damage to the coil during handling and transportation.
- Q: I am buying a knife for my future husband for his wedding gift and I was wondering what is better carbon steel or stainless steel?
- It depends on what your husband plans to do with the knife. In general, stainless steel knives are more resistant to rust and corrosion but carbon steel knives hold a sharp edge for longer. Those are only general statements, because high carbon knives can be coated to resist rust, and some high quality stainless steel knives can hold a great edge. There are many different metal alloys used for knives, and each one has its own properties. If I were you, I would buy a high carbon steel knife, unless you think your husband would use the knife under conditions that might make it rust (fishing or boating, for example).
- Q: How are steel coils used in the production of automotive parts?
- Steel coils are used in the production of automotive parts as they provide a durable and flexible material for making various components such as body panels, chassis, and suspension parts. The coils are processed through specialized machinery to cut, shape, and form the steel into the required parts, ensuring strength and precision. Additionally, the coils can be treated or coated to enhance corrosion resistance, further improving the longevity and performance of automotive parts.
- Q: Having a new kitchen and would like to know the pros and cons of stainless steel as opposed to white appliances. I can only think of finger marks on the SS, which I believe are difficult to remove. Anyone had both that they could advise please?
- We got rid of the Stainless Steel because they showed every smudge, finger print and smear. Very hard to clean. Harder to keep clean. I recommend any color except Stainless Steel.
- Q: Can steel coils be stored in unheated warehouses?
- Yes, steel coils can be stored in unheated warehouses as long as proper precautions are taken to prevent moisture and corrosion.
- Q: How are steel coils manufactured?
- Steel coils are manufactured through a multi-step process that involves heating and shaping steel slabs, followed by passing them through a series of rolling mills to reduce their thickness and increase their length. The coils are then cooled, inspected for quality, and finally, wrapped and ready for shipping.
