Description of ASTM 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 ASTM 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 protected against UV radiation?
- Steel coils are protected against UV radiation through a process known as coil coating. Coil coating involves applying a protective layer of paint or coating to the surface of the steel coil. This coating acts as a barrier between the steel and UV radiation, preventing direct exposure of the metal to the harmful effects of the sun's ultraviolet rays. The protective coating used for steel coils is specially formulated to provide excellent resistance against UV radiation. It typically contains pigments and additives that are designed to absorb or reflect UV light, reducing the amount of radiation that reaches the steel surface. Furthermore, the coating is applied in multiple layers to ensure maximum protection. The first layer, known as the primer, enhances adhesion to the steel surface and provides additional corrosion resistance. The subsequent layers, such as the base coat and topcoat, offer improved durability and UV resistance. In addition to the coating itself, the steel coils can be further protected against UV radiation by storing them in shaded areas or using covers to shield them from direct sunlight when stored outdoors. This additional precaution helps minimize the exposure of the coated steel coils to UV radiation, thereby prolonging their lifespan and maintaining their appearance. Overall, the combination of a high-quality protective coating, proper storage, and handling practices ensures that steel coils are effectively shielded against the damaging effects of UV radiation, allowing them to maintain their structural integrity and aesthetic appeal over an extended period of time.
- Q:What are the common applications of pre-painted galvanized steel coils?
- Pre-painted galvanized steel coils have a wide range of common applications. They are commonly used in the construction industry for roofing, siding, and cladding applications due to their durability, corrosion resistance, and aesthetic appeal. These coils are also used in the automotive industry for manufacturing various parts and components. Additionally, pre-painted galvanized steel coils are utilized in the manufacturing of appliances, furniture, and storage systems.
- Q:What are the different methods of stretch leveling steel coils?
- There are several methods of stretch leveling steel coils, each with its own advantages and applications. 1. Roller Leveling: This method involves passing the steel coil through a series of rollers that apply pressure to stretch and flatten the material. It is a widely used method for leveling steel coils and offers good control over the leveling process. Roller leveling is suitable for thin and medium gauge steel coils. 2. Tension Leveling: In this method, the steel coil is subjected to high tension forces applied by a set of bridle rolls. The tension helps to elongate and flatten the material, resulting in a level and stress-free coil. Tension leveling is particularly effective for thicker and harder steel coils. 3. Laser Leveling: Laser technology is employed in this method to measure and correct any imperfections in the steel coil. A laser scanner scans the surface of the coil and detects variations, which are then adjusted by a laser beam. Laser leveling offers high precision and is suitable for leveling sensitive and high-value steel coils. 4. Stretcher Leveling: This method involves stretching the steel coil beyond its yield point, which causes the material to permanently deform and eliminate any residual stresses. Stretcher leveling is commonly used for heavy gauge coils and can achieve significant flatness improvements. 5. Tensionless Leveling: As the name suggests, tensionless leveling is performed without applying tension to the steel coil. Instead, hydraulic or pneumatic pressure is used to stretch and flatten the material. This method is suitable for delicate or sensitive steel coils that may be prone to damage under high tension forces. Each method of stretch leveling steel coils has its own advantages, such as control, precision, or suitability for specific types of steel coils. The choice of method depends on factors like the thickness, hardness, and quality requirements of the steel coil, as well as the desired flatness and surface finish.

- Q:How are steel coils used in the production of metal cladding?
- Steel coils serve as the primary raw material for metal cladding production. Metal cladding involves covering a building's exterior with a layer of steel to enhance its durability, aesthetics, and insulation. To begin the manufacturing process, galvanized steel coils are used. These coils are made by coating steel with zinc to prevent corrosion. They are then unrolled and fed into a roll-forming machine, which shapes them into the desired profile for the cladding panels. Once the coils are formed, they undergo various processes to improve their properties. These processes include cutting, perforating, and embossing to create patterns, textures, or openings in the panels. Additional protective layers, such as paint or powder coating, can also be applied to enhance corrosion resistance and appearance. The shaped and processed coils are assembled into metal cladding panels. These panels interlock seamlessly to create an appealing exterior for buildings. They can be attached to the building's structure using screws, clips, or adhesives. Using steel coils in metal cladding production offers several advantages. Steel is a strong and durable material, making it suitable for exterior applications that require resistance to weathering, impact, and other environmental factors. It also allows for a wide range of design options and customization. In summary, steel coils are essential in the production of metal cladding. They serve as the raw material, which is shaped, processed, and assembled into panels that enhance buildings' protection, aesthetics, and insulation properties.
