Description of Prepainted Aluminum Zinc Rolled Coil for Construction roof
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 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.
Applications of Prepainted Aluminum Zinc Rolled Coil for Construction roof
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.

- Q:i have a sword and some knives that have this grade steel. so is it a high grade or low grade? and how can i tell the differance between a high grade and a low grade?
- For throwing knives, 440 isn’t necessarily a bad choice. Does it list whether it is 440c or 440b? That matters somewhat. The advantages of 440 Stainless is that it’s relatively hard (for a stainless), it resists rust significantly, and it’s not so hard that it would shatter or break. On the down side 440 is notorious for not taking or holding an edge, but for a throwing knife, that’s probably not much of an issue. If you’re looking for something to train with, you’re fine here. It’s plenty of steel enough to stick in wood or other targets. Odds are it won't bend if you slam it into some wood. If it lands on concrete, eh, it's going to scratch and all that jazz, and it might hurt the tip if it hits first, but as has been said, you can use a file or grinder to get the tip back.
- Q:How long does the coating on steel coils last?
- The longevity of the coating on steel coils depends on various factors such as the type of coating used, the environmental conditions it is exposed to, and the maintenance practices. However, on average, a well-applied coating can last anywhere from 10 to 20 years before requiring reapplication or maintenance.
- Q:I need to penetrate steel on my car but don't know which bit to use. Are there special bits for steel?
- Yes, they'll be marked HSS, High Speed Steel.
- Q:How are steel coils used in the manufacturing of packaging materials?
- Steel coils are used in the manufacturing of packaging materials as they provide strength and stability to the packaging structure. They are commonly used as a core material for packaging tubes, enabling them to withstand heavy loads and prevent deformation. Additionally, steel coils are utilized in the production of steel straps, which are widely used for securing packages and pallets, ensuring safe transportation and storage of goods.
- Q:In pounds per square inch what is the tensile strength of strong steel?
- The term tensile strength refers to the amount of tensile (stretching) stress a material can withstand before breaking or failing. The ultimate tensile strength of a material is calculated by dividing the area of the material tested (the cross section) by the stress placed on the material, generally expressed in terms of pounds or tons per square inch of material. Tensile strength is an important measure of a material's ability to perform in an application, and the measurement is widely used when describing the properties of metals and alloys.
- Q:Are steel coils corrosion-resistant?
- Yes, steel coils can be corrosion-resistant depending on the type of steel used and any additional protective coatings applied.
- Q:What are the main challenges in handling and processing steel coils?
- The main challenges in handling and processing steel coils include their large size and weight, the risk of damage during transportation and storage, the need for specialized equipment and facilities, ensuring proper handling to prevent injury to workers, and addressing the potential for corrosion and rust. Additionally, the variability in coil dimensions and surface conditions can pose difficulties in achieving precise and consistent processing results.
- Q:How do steel coils contribute to the agricultural sector?
- Steel coils contribute to the agricultural sector in various ways. Firstly, steel coils are used in the manufacturing of agricultural machinery and equipment such as tractors, harvesters, and irrigation systems. These machines are essential for efficient farming operations, helping farmers increase productivity and reduce labor costs. The strength and durability of steel coils ensure that the machinery can withstand the harsh conditions of the agricultural environment. Additionally, steel coils are used in the construction of storage facilities and warehouses for storing agricultural products. These structures need to be strong and resistant to external elements to protect the crops from damage. Steel coils provide the necessary strength and stability required for constructing these storage facilities, ensuring the safe storage of agricultural produce. Furthermore, steel coils are used in the fabrication of fencing and other agricultural infrastructure. Fencing is crucial in protecting crops from animals and preventing trespassing. Steel coils provide a robust material for fencing, ensuring the security and protection of agricultural lands. Moreover, steel coils are utilized in the production of irrigation pipes and systems. Efficient irrigation is vital for the growth and yield of crops, especially in areas with limited water resources. Steel coils are used to manufacture pipes that can withstand high pressure and are resistant to corrosion, ensuring the efficient distribution of water throughout the agricultural fields. In summary, steel coils play a significant role in the agricultural sector by providing the necessary materials for manufacturing machinery, constructing storage facilities, fencing, and irrigation systems. The strength, durability, and resistance to harsh conditions make steel coils an essential component in enhancing agricultural productivity, protecting crops, and ensuring efficient farming practices.
- Q:i have searched high and low, but can't find information anywhere!bainitic and pearlitic steels are too in depth, just would like to know if it is hsla steel, or mild steel, or stainless steel etc...thank you in advance :)
- Hoghead has it right, it is quite mild steel, every time they try harder steel it does not stand up to the stress and breaks more readily. Rail, odd as it seems can get corrugated and rough same as a dirt road and needs to be reground from time to time to reshape the top part of the rail. Rust is not a problem on a track in use so stainless would be a unnecessary expense. Also, in high wear places, specialized welding crews come in in add new material to the most worn parts, as in switches and then regrind it to the proper profile, mild steel accepts this much better than a harder steel would.
- Q:How are steel coils used in the production of electrical relays?
- Steel coils are a crucial component in the production of electrical relays as they are used to create a magnetic field. When an electrical current passes through the coil, the magnetic field is generated, which then attracts or repels a movable contact, allowing the relay to switch on or off an electrical circuit. Hence, steel coils play a vital role in the functioning of electrical relays by facilitating the control of current flow.
