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: Can steel coils be welded together?
- Yes, steel coils can be welded together. Welding is a common technique used to join metals, including steel coils. It involves melting the edges of the coils and fusing them together using a filler material. This process creates a strong and durable bond between the coils, allowing them to be joined and used as a single unit. Welding steel coils together is commonly done in various industries, such as manufacturing, construction, and automotive, to create larger structures or components. However, it is important to ensure proper welding techniques and quality control measures are followed to ensure the integrity and strength of the weld joint.
- Q: did bible stated that steel is coming from outer space. i mean meteor rocks that enter our earth sistem contains the minerals iron.
- If you are using either an NAB or RSV translation of the Bible, steel is only mentioned once in the Bible. Compare Nahum 2:4 (NAB) and Sirach 31:26 (RSV). There is no reference of an outer space in the Bible. Furnace is mentioned in Sirach. It takes a lot of energy to mix Iron and Carbon to produce steel. The alloy can only be produced in the furnace at an extremely high temperature.
- Q: I work in a steel foundry 10-12 hours a day where we melt and pour stainless steel tubes. The pour temperature for some of them is very close to the boiling point of stainless steel (about 3800 degrees) because it has to be VERY liquid for the application we use it. Anyway, it does boil a little and we breath in the vapours which I can assure you ARE indeed vapourized stainless steel (it collects and cools on everything and makes a nice shiny coating). Ok, so to the question, does breathing vapourized stainless steel all day pose a health risk such as cancer? Anyone know? I'm just curious.
- I would imagine it's not good. I doubt cancer but I suppose it may be possible. Shouldn't you guys have respirator gear on? Where's OSHA when you need'em? ;)
- Q: How are steel coils used in the oil and gas industry?
- Steel coils are used in the oil and gas industry for various purposes such as storage, transportation, and processing of oil and gas products. These coils are commonly used in the construction of pipelines, tanks, and equipment due to their strength, durability, and resistance to corrosion. They are also utilized in the production of offshore platforms and drilling rigs. Overall, steel coils play a crucial role in ensuring the efficient and safe extraction, transportation, and processing of oil and gas resources.
- Q: How are steel coils inspected for surface finish variations?
- Steel coils are inspected for surface finish variations using visual examination, mechanical methods such as gauges and calipers, and non-destructive testing techniques like magnetic particle inspection or ultrasonic testing.
- Q: I am a complete idiot when it comes to anything musical, so please forgive me if this is a stupid question. I bought my son his first guitar, acoustic and didnt realize until after I purchased it that it has steel strings. Can I have the strings changed from steel to nylon???
- If it's a Fender, you will need wire cutters to cut the brass barrel shape off the end to feed the string into the clamp. Otherwise on most guitars you just anchor the string barrel at the bridge end, feed the string along the neck and through the hole in the capston and turn the string capston by using the handle The surplus string can just be coiled up. I never had a string winder for years, ---bit of a gimmick --- --but does save time. A point worth noting if considering splashing out on a string winder is that some of them are equipped with a wire cutter as well. 2 Tools in one eh!!
