Structure of Al-Zinc coated steel coil
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 Al-Zinc coated steel 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.
Applications of Al-Zinc coated steel coil
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: Whats the difference in composition? When LTCS is used generally?Whats the temperature range, that these materials can be used? Is there any relation between Killed carbon steel, LTCS, stainless steel, carbon steel(normal)? How to categorise/classify these?Thankyou very much in advance..
- When exposed to elevated temperatures, quenched and tempered steels are more susceptible than normalized steels to permanent reduction in strength. This is especially true when exposure temperature begins to approach tempering temperature used when the parts were produced. In addition to losing strength, tempered steels also may experience reduced impact toughness after being exposed to long-term elevated temperatures. General belief is that this is the reason for LCC's reduced maximum allowable temperature limit of 345°C / 650°F in B16.34.
- Q: In the game RuneScape, the concept of the fictitious metal, Rune has intrigued me. On an equal area AND weight basis (with a possible 10 lb exception) what metal is 256% stronger than steel?
- If you mean Mild steel which has a Ultimate Tensile Strength of 40 Kilograms/ sq.mm, there are many Heat-treated Alloy steels which are much stronger than this. For example, steels conforming to Grade-150-125, of ASTM A148 has a Ultimate Tensile Strength of 102 to 108 Kilograms/ sq.mm.
- Q: I am a beginner (never played before!) and I am going to try to teach myself since I think it is a lovely instrument. I am fourteen-years-old so I am not 'adult-size', haha. Anyway, what is difference between nylon strings and steel strings?Thanks :)
- Small guitars easier to find in classical range. I assume their must be small steel strings but not seen them.
- Q: I want to start getting throwing knives and i was wondering what material is best for quality, but still cheap. I also saw some 440 stainless steel knives that i liked and wanted to know if the material was good
- Good steel ain't cheap, cheap steel ain't good... If you're just starting out (practicing anyways), I would be less concerned about the material and more concerned about the style and shape of the blade to gain consistency in your technique... When you start getting proficient for competitions and such... then I'd start investigating steel grades... Anyways, here's a summary from the wiki: Type 440—a higher grade of cutlery steel, with more carbon, allowing for much better edge retention when properly heat-treated. It can be hardened to approximately Rockwell 58 hardness, making it one of the hardest stainless steels. Due to its toughness and relatively low cost, most display-only and replica swords or knives are made of 440 stainless. Available in four grades: 440A, 440B, 440C, and the uncommon 440F (free machinable). 440A, having the least amount of carbon in it, is the most stain-resistant; 440C, having the most, is the strongest and is usually considered more desirable in knifemaking than 440A, except for diving or other salt-water applications.
- Q: Can steel coils be coated with organic materials?
- Yes, steel coils can be coated with organic materials.
- Q: How are steel coils processed for cutting to length or blanking?
- Steel coils are processed for cutting to length or blanking through a series of steps. First, the coil is uncoiled and flattened to remove any inherent deformities. Then, the edges are trimmed to ensure uniform width and straightness. Next, the coil is fed into a leveling machine to eliminate any remaining inconsistencies in thickness. Once leveled, the steel is conveyed to a cutting machine where it is precisely cut into individual sheets of desired length or blanks. These sheets or blanks are then stacked and prepared for further fabrication or distribution.
- Q: How are steel coils shipped internationally?
- Steel coils are shipped internationally using various methods to ensure their safe and efficient transportation. The most common method is through container shipping, where steel coils are loaded into standard shipping containers for transportation. These containers are specifically designed to handle heavy and bulky cargo, such as steel coils. To load the steel coils into the containers, they are usually stacked horizontally and secured with steel strapping or metal bands to prevent movement during transit. This ensures stability and minimizes the risk of damage. Additionally, wooden or metal dunnage may be used to separate and secure the coils to further prevent shifting. Once loaded, the containers are sealed and transported to the port using trucks or trains. At the port, the containers are loaded onto cargo ships, either by crane or using specialized equipment such as roll-on/roll-off (RO-RO) vessels or semi-submersible ships. These ships provide a secure environment for the steel coils during the journey, protecting them from weather conditions and potential damage. During the voyage, the steel coils are subjected to various safety measures to prevent corrosion and protect their integrity. These measures include applying protective coatings, such as oil or special paints, and using desiccants or humidity control systems inside the containers to regulate moisture levels and minimize the risk of rusting. Upon reaching the destination port, the containers are unloaded from the ship and transferred to trucks or trains for further transportation to their final destination. At this stage, the steel coils may undergo customs clearance and inspection procedures before being delivered to the intended recipients. Overall, international shipping of steel coils involves meticulous planning, secure packaging, and the use of specialized containers and equipment to ensure their safe and successful transport.
- Q: How are steel coils stored in warehouses?
- Steel coils are typically stored in warehouses by stacking them horizontally on top of each other, often using specialized racks or shelves designed to support their weight. Coils are usually aligned in rows with adequate space between each stack to allow for easy access and movement of the coils. Additionally, some warehouses may use protective materials, such as wooden or plastic spacers, to prevent scratching or damage to the coils during storage.
- Q: What is the tensile strength of a steel coil?
- The maximum stress or force that a steel coil can endure before breaking or undergoing permanent deformation is known as its tensile strength. This property measures the coil's capacity to withstand stretching or pulling apart. The specific tensile strength of a steel coil can vary based on factors such as the type and grade of steel used, the manufacturing process, and any additional treatments or coatings applied. Typically, steel coils exhibit high tensile strength, which falls within the range of 300 to 2,000 megapascals (MPa). When considering the suitability of a steel coil for applications in industries like construction, automotive, or manufacturing, the tensile strength is a crucial factor to take into account.
- Q: I know that carbon steels and alloy steels are different but are carbon steels still alloys?Thanks!
- Yes. it's an alloy of iron and carbon. Carbon steel can either mean plain carbon steel which is steel that doesn't have significant amounts of other elements, like chromium, manganese, or molybdenum. It can also be used to refer to ANY steel that is NOT a stainless steel. Alloy steel is any steel that has greater than 1% of other elements added to it besides carbon. Stainless steel might be in a certain sense be considered alloy steel but I think most people in the steel business consider it as it's own separate material from carbon steels. Many stainless steels contain only trace amounts of carbon, so they should rightly be considered iron-chromium alloys, not steel, which by default refers to iron-carbon alloys. Note that nearly all modern carbon steels also contain 0.2%-0.5% manganese and silicon. Even steels that are otherwise considered plain carbon and not alloy steels. Mn and Si are added because they prevent defects in cast steel ingots, and hot rolled items like billets and plates. However at low levels they don't affect the properties of the steel greatly.
