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: How are steel coils processed for painting or coating?
- Steel coils are processed for painting or coating through a series of steps. Firstly, the coils are cleaned to remove any dirt, oil, or scale using various methods like acid pickling or mechanical cleaning. Then, a primer or chemical treatment is applied to enhance the adhesion of the paint or coating. Next, the coils are dried to remove moisture and ensure proper adhesion. Finally, the paint or coating is applied to the coils using methods such as coil coating or electrostatic spraying, and then the coated coils are cured to achieve the desired finish and durability.
- Q: What are the common methods of storing steel coils in warehouses?
- There are several common methods for storing steel coils in warehouses, depending on the size and weight of the coils, as well as the available space and resources in the warehouse. Here are some of the most commonly used methods: 1. Block stacking: This method involves stacking the steel coils directly on top of each other, forming a block. The coils are typically aligned in rows and columns, with wood or rubber blocks placed between the layers to provide stability and prevent damage. 2. Racking systems: Racks are often used to store steel coils in warehouses. There are various types of racks, including cantilever racks, coil racks, and structural racks. These racks provide a structured system for organizing and storing the coils, allowing for easy access and efficient use of space. 3. Coil cradles: Coil cradles are a type of storage equipment specifically designed for steel coils. They consist of a series of cradles or saddles that securely hold the coils in place. These cradles can be stacked on top of each other to maximize vertical space utilization. 4. Coil pads: Coil pads are flat platforms made from materials such as wood, rubber, or foam. They are placed on the warehouse floor, and the steel coils are then stacked directly on top of them. Coil pads help to distribute the weight of the coils evenly and protect them from damage caused by contact with the floor. 5. Slit coil storage: Slit coils, which are narrower and lighter than full-size coils, can be stored using specialized storage systems. These systems often consist of racks or shelves equipped with dividers or separators to keep the coils organized and prevent them from unraveling. It is important to note that regardless of the storage method used, safety precautions should be followed when handling and storing steel coils in warehouses. This includes ensuring proper weight distribution, using appropriate lifting equipment, and adhering to industry-specific guidelines and regulations.
- Q: How are steel coils used in the construction of bridges?
- Steel coils are indispensable in the construction of bridges, as they are typically crafted from high-strength steel and serve various purposes throughout the bridge-building process. One of the primary functions of steel coils in bridge construction lies in the production of structural components. These coils are cut, shaped, and welded together to form beams, columns, and trusses, thus ensuring the bridge's stability and durability. Moreover, steel coils are employed in fabricating bridge decks, which serve as the upper surface of the bridge, providing a pathway for vehicles and pedestrians. The coils are rolled into sheets and further processed to create the deck plates, which are then assembled and attached to the bridge's structural elements. Another significant application of steel coils in bridge construction involves reinforcing concrete structures. Rebar, derived from steel coils, is embedded within the concrete to enhance its strength and resistance to tension. Strategically placed in locations such as bridge piers and abutments, the rebar provides additional support, preventing cracking or collapse. Furthermore, steel coils find utility in the manufacturing of bridge expansion joints. These vital components allow bridges to expand and contract in response to temperature fluctuations and external factors. By shaping steel coils into plates or strips, expansion joints can be easily installed and adjusted to accommodate the bridge's movement. To summarize, steel coils play a vital role in the construction of bridges, contributing to the manufacturing of structural components, bridge decks, reinforcing concrete structures, and expansion joints. With their strength and support, steel coils facilitate the creation of safe and reliable bridges, capable of withstanding diverse loads and environmental conditions.
- Q: Does anyone know what is 12 gage Cold Rolled Steel meaning? Also, help me to describe it.Thank you so muck ~!Mark Lin
- Steel thickness is measured by gages. 16 gage is approximately 1/16th of an inch. The larger the number (say, 24), the thinner the steel. Steel is made from large metal bars (4'x12', about 8 thick) that pass through presses to get thinner and thinner. If the final stages of rolling are done with pressure and not heat, it is cold rolled. It often gets galvanized to prevent rusting. Hope this helps.
- Q: Can steel coils be coated with anti-graffiti materials?
- Yes, steel coils can be coated with anti-graffiti materials. These materials create a protective layer that can prevent graffiti from adhering to the surface, making it easier to remove any unwanted markings.
- Q: How are steel coils used in the manufacturing of conveyor belts?
- Steel coils are used in the manufacturing of conveyor belts as they provide strength, durability, and flexibility to the belt structure. These coils are typically used as reinforcements or as the core material to enhance the belt's load-bearing capacity and resistance to tension and impact. By incorporating steel coils, conveyor belts can effectively transport heavy materials over long distances while maintaining stability and longevity.
- Q: What are the different types of steel coil surface treatments?
- There are several different types of steel coil surface treatments, including hot-dip galvanizing, electro-galvanizing, painting, and powder coating.
- Q: The steel is orangish in colour and is mostly made of copper
- Steel is an alloy of iron and carbon and optionally one or more of numerous other materials. Copper is normally not used, except sometimes in small percentages. Steel is never yellow or orange in color. Reactivity of steel depends on the materials it is alloyed with. Chromium and nickel with steel make stainless steel, which is much less prone to reactive than iron. .
- Q: Personally, I like Steel Cage matches to end in pinfalls. One of the biggest selling points of a Cage match is that it is to keep the competitors in and keep others out; essentially ensuring that it's a 1 on 1 match. As a result, I believe that pinfalls or submissions are important - but I know there's a lot of people that believe cage matches should only end in escape. What do you think??
- Escape. It is more fun to watch and gets fans adrenaline pumping
