Description of RAL Scale Z65 Prepainted Rolled Steel Coil for Construction Roofing
Prepainted Rolled steel Coil 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 RAL Scale Z65 Prepainted Rolled Steel Coil for Construction Roofing
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 used in the production of metal enclosures?
- Steel coils are widely used in the production of metal enclosures due to their versatility and strength. These coils, which are typically made from high-quality steel, serve as the primary raw material for manufacturing metal enclosures. Firstly, the steel coils are unrolled and flattened to the desired thickness using specialized machinery. This process ensures that the coils are in a suitable form for further processing. The flattened steel is then cut into specific sizes and shapes, depending on the design requirements for the metal enclosure. Next, the cut steel pieces are formed into the desired shape using various techniques such as bending, folding, and welding. These processes allow the steel to be molded into the required dimensions and structure of the metal enclosure. The inherent strength and durability of the steel coils ensure that the final product is sturdy and can withstand external forces or impacts. Additionally, steel coils can be coated with protective layers such as galvanization or powder coating to enhance their resistance to corrosion, rust, or other environmental factors. This coating helps to prolong the lifespan of the metal enclosure and maintain its aesthetic appeal. Moreover, the use of steel coils in the production of metal enclosures allows for customization and flexibility. The coils can be easily manipulated to create complex shapes or designs, enabling manufacturers to cater to specific customer requirements. This adaptability makes steel coils a preferred choice in industries such as automotive, electronics, and construction, where metal enclosures are widely used. In summary, steel coils play a crucial role in the production of metal enclosures by providing a strong and versatile raw material. These coils are transformed into the desired shape and size, ensuring the durability and functionality of the enclosures. With their customizable nature and protective coatings, steel coils offer a cost-effective solution for manufacturing high-quality metal enclosures.
- Q: What are the different types of steel coil surface defects?
- There are several different types of steel coil surface defects that can occur during the manufacturing or handling process. Some of the common types include: 1. Rust: Rust is a common surface defect that occurs when the steel coil is exposed to moisture or oxygen. It appears as a reddish-brown discoloration on the surface of the coil. 2. Scratches: Scratches are superficial marks that can occur during handling or transportation of the steel coil. They can vary in depth and severity, ranging from light surface scratches to deep gouges. 3. Stains: Stains are another type of surface defect that can occur due to exposure to chemicals or other substances. They can appear as discolored patches on the surface of the coil, and may be difficult to remove. 4. Roll marks: Roll marks are impressions or indentations that can occur during the rolling process. They are caused by uneven pressure or misalignment of the rolls, and can appear as lines or patterns on the surface of the coil. 5. Edge wave: Edge wave is a defect that occurs when the edges of the coil are not perfectly flat. It can cause the edges to appear wavy or uneven, and may affect the overall appearance and performance of the coil. 6. Oil spots: Oil spots are surface defects that occur when oil or lubricants used in the manufacturing process are not properly removed. They can appear as dark spots or patches on the surface of the coil, and may affect the adhesion of coatings or paints. 7. Pitting: Pitting is a defect that appears as small, shallow depressions or pits on the surface of the coil. It can be caused by factors such as corrosion, uneven cooling, or impurities in the steel. 8. Holes: Holes are more severe surface defects that can occur due to a variety of reasons, such as corrosion, mechanical damage, or manufacturing errors. They can range in size and can significantly affect the structural integrity of the coil. It is important to address these surface defects promptly to ensure the quality and performance of the steel coil. Regular inspections, proper handling, and appropriate surface treatments can help minimize the occurrence of these defects.

- Q: How are steel coils heat treated?
- Annealing is the method used to heat treat steel coils, resulting in improved mechanical properties and overall performance. To achieve this, the coils are heated to a specific temperature and slowly cooled down. This process relieves internal stresses within the steel and enhances its performance. To begin the heating process, the steel coils are raised to a critical temperature, typically between 800°C and 900°C, depending on the desired outcome. They are then maintained at this temperature for a specific period of time, allowing for the transformation of the steel's microstructure. Once the desired time has passed, the heated coils are carefully cooled down in a controlled manner. This gradual cooling process is crucial as it allows for a uniform and refined microstructure. It also helps prevent the formation of internal stresses that could weaken the steel. The annealing process can be conducted in various atmospheres, such as air, nitrogen, or hydrogen. The choice of atmosphere depends on the specific requirements and properties desired for the steel coils. For example, annealing in a protective atmosphere like nitrogen or hydrogen can prevent oxidation or decarburization of the steel surface. In conclusion, annealing is a crucial step in heat treating steel coils, resulting in improved mechanical properties, enhanced formability, and the desired characteristics for industrial applications.
- Q: What are the different types of steel coil slitting methods?
- There are three main types of steel coil slitting methods: rotary slitting, loop slitting, and oscillating slitting. Rotary slitting involves using a circular knife to cut the coil into smaller strips. Loop slitting involves creating a loop in the coil and then cutting it using a straight knife. Oscillating slitting involves using a reciprocating knife to make a back-and-forth motion while cutting the coil. These methods allow for precise and efficient slitting of steel coils into narrower strips.
