Description of 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 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.
Applications of Prepainted Rolled steel Coil for Construction Roofing

- Q: What are the different types of steel coil cutting machines?
- In the market, there is a wide range of steel coil cutting machines available, each tailored to meet specific needs and requirements. Some commonly used types include: 1. Slitting Machines: These machines are utilized to cut steel coils into narrower strips. Equipped with multiple circular blades, they are capable of making precise cuts along the length of the coil, enabling the production of narrower coils or strips. 2. Cut-to-Length Machines: Designed to cut steel coils into specific lengths, these machines possess the ability to accurately measure and cut the coil to the desired length, ensuring uniformity and precision. 3. Rotary Shears: Rotary shears are robust cutting machines that can handle thicker and larger steel coils. Utilizing a rotating blade, they are suitable for cutting thicker gauge materials. 4. Multi-Blanking Machines: Intended for cutting steel coils into multiple smaller blanks simultaneously, these machines have the capability to cut the coil into various shapes and sizes. This makes them ideal for producing multiple parts from a single coil. 5. Slit and Cut-to-Length Combination Machines: These machines integrate the functionalities of both slitting and cut-to-length machines, enabling the cutting of narrow strips and lengths in a single process. They offer versatility and efficiency, saving time and increasing productivity. Each type of steel coil cutting machine possesses distinct advantages and is suitable for specific applications. The choice of machine depends on factors such as coil thickness, desired strip width, required length accuracy, and production volume.
- Q: What are the different types of steel coil cutting blades?
- Various types of steel coil cutting blades exist, each specifically designed for particular cutting purposes. 1. Slitting Blades: These blades are utilized to cut steel coils into narrow strips. They possess a straight cutting edge and come in different widths to accommodate various slitting needs. Industries like automotive, construction, and metal fabrication commonly employ these blades. 2. Shearing Blades: These blades are created to cut steel coils into flat sheets. They feature a curved cutting edge that enables a clean and precise cut. Steel service centers, where large coils are transformed into flat sheets for further manufacturing processes, frequently utilize shearing blades. 3. Circular Blades: Also known as rotary blades, these blades are employed for continuous cutting of steel coils. With a circular shape adorned with sharp teeth along the edge, they can effectively cut through the coil as it passes through the cutting machine. Industries such as packaging, printing, and paper manufacturing often make use of circular blades. 4. Guillotine Blades: These blades are employed to cut steel coils in a straight downward motion. Possessing a vertically moving straight cutting edge, they can effectively slice through the coil. Guillotine blades are frequently used in heavy-duty cutting applications that involve thick steel coils or large quantities of material. 5. Slitter Knives: Similar to slitting blades, slitter knives are typically smaller and employed in slitting machines that require multiple blades. Industries requiring high-precision slitting, such as electrical transformer production or precision metal stamping, often rely on slitter knives. Each type of steel coil cutting blade possesses unique characteristics and designs that render them suitable for specific cutting tasks. The appropriate blade selection depends on factors like steel coil thickness and width, desired cut quality, and specific application requirements.

- Q: How are steel coils used in the manufacturing of defense equipment?
- Steel coils are used in the manufacturing of defense equipment as they provide the necessary strength, durability, and flexibility required for various applications. These coils are often processed and shaped into components such as armor plates, vehicle frames, ammunition casings, and other structural parts. The high tensile strength and resistance to impact and deformation make steel coils an ideal material for protecting military personnel and assets, ensuring the reliability and effectiveness of defense equipment.
- Q: How are steel coils used in the production of roofing panels?
- To manufacture roofing panels, steel coils are indispensable. These coils, usually composed of galvanized or coated steel, serve as the fundamental material for producing robust and top-notch roofing panels. Initially, the steel coils undergo a sequence of operations in a production facility. These operations involve flattening, cleaning, and shaping the coils to achieve the desired dimensions and profiles for the roofing panels. This process guarantees that the steel coils possess uniform thickness and are devoid of any impurities or flaws that could compromise the final product's integrity. Once the steel coils are prepared, they are fed into a roll forming machine. In this machine, the coils are gradually bent and shaped into the specific design and size required for the roofing panels. The roll forming process imparts the panels with their distinct corrugated or standing seam profiles, which enhance their strength and ability to withstand various weather conditions. After the roll forming process, the steel coils are divided into individual roofing panels of the desired length. These panels then undergo further processing to incorporate additional features, such as coatings or finishes, to enhance protection against corrosion and improve aesthetic appeal. Protective layers, such as zinc or paint, are often applied to the steel coils to enhance their resistance to rust, UV rays, and other environmental factors. Lastly, the roofing panels are packaged and transported to construction sites or distributors for installation. The utilization of steel coils in the production of roofing panels ensures that the final product is sturdy, long-lasting, and capable of withstanding heavy loads, strong winds, and other external forces. Steel is renowned for its high tensile strength, making it an ideal material for creating durable roofing panels. In conclusion, steel coils play a vital role in the production of roofing panels. Through a series of manufacturing processes, they are transformed into the desired dimensions and profiles, ensuring consistency and quality. The resulting roofing panels are not only visually pleasing but also highly resilient, providing superior protection and longevity for buildings.
