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.

- Q: How are steel coils inspected for oil or rust residues?
- Oil or rust residues in steel coils are examined through a series of visual and physical checks. Trained personnel conduct the initial visual inspection, closely scrutinizing the steel surface for any indications of oil or rust residues. They look for discolouration, stains, or any unusual signs that could suggest the presence of contaminants. Besides the visual inspection, different techniques are employed to detect oil or rust residues. One commonly used method is solvent cleaning. A solvent is applied to the steel coil's surface, and if there are any oil or rust residues, they will dissolve and become visible. This enables inspectors to identify and eliminate any contaminants. Ultrasonic testing is another technique used for inspection. Ultrasonic waves are transmitted through the steel coil, and any variations in the reflections of these waves can indicate the presence of oil or rust residues. This non-destructive testing method provides a more comprehensive analysis of the steel's condition, ensuring a thorough inspection. In addition, specialized equipment such as magnetic particle inspection or eddy current testing may be utilized. Magnetic particle inspection involves applying magnetic particles to the steel surface, which will gather around areas with oil or rust residues. Similarly, eddy current testing employs electromagnetic induction to identify surface irregularities caused by contaminants. Overall, a combination of visual inspection and various testing techniques is employed to ensure a meticulous examination of steel coils for oil or rust residues. These rigorous inspections guarantee that the coils meet the required quality standards and are free from any contaminants that may compromise their performance or durability.
- Q: How are steel coils inspected for flatness variations?
- Steel coils are inspected for flatness variations using specialized equipment such as laser or optical scanning systems. These systems measure the surface profile of the coil and identify any deviations from the desired flatness. The data collected is then analyzed to determine the extent of the variations and whether they meet the required tolerances.
- Q: How are steel coils protected from chemical damage?
- Steel coils are typically protected from chemical damage through various methods such as applying protective coatings or using barrier films. These protective measures act as a barrier between the steel surface and any potentially corrosive chemicals, preventing direct contact and minimizing the risk of chemical damage.
- Q: How are steel coils used in the manufacturing of construction excavators?
- Steel coils are used in the manufacturing of construction excavators as they are often the primary material for constructing the structural components of the excavator.

The steel coils are typically used as the main structural component in the seat belt, ensuring that it can withstand high levels of force during an impact. Additionally, the coils help to maintain the proper tension in the seat belt, ensuring that it functions effectively in restraining the occupants in the event of a collision.
- Q: What are the different testing methods used for steel coils?
- There are several testing methods used for steel coils, including visual inspection, dimensional measurements, hardness testing, chemical composition analysis, and various non-destructive testing techniques such as ultrasonic testing, magnetic particle testing, and eddy current testing. These methods help ensure the quality and integrity of steel coils by detecting any defects, flaws, or deviations from the required specifications.
- Q: I already have the county permits and bank loan, but the foundation hasn't been poured. Is it too late to convert to steel?
- Steel is going to be a whole different world. You will need to go back to square one and get house plans that are drawn for structural steel. First thing you need to do is find a builder that knows how to build with steel and get an idea of the price.
- Q: How are steel coils used in the manufacturing of railway equipment?
- The strength, durability, and versatility of steel coils are crucial factors in their importance in the manufacturing of railway equipment. These coils, typically made from high-quality steel, are extensively used in various applications throughout the railway industry.
