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
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.

- Q:How are steel coils inspected for surface defects after processing?
- Steel coils are inspected for surface defects after processing through visual inspection, magnetic particle inspection, or ultrasonic testing. Visual inspection involves examining the surface for any visible defects such as scratches, dents, or corrosion. Magnetic particle inspection uses magnetic fields and iron particles to detect surface cracks or defects that may not be visible to the naked eye. Ultrasonic testing involves using high-frequency sound waves to detect internal and surface defects in the steel coils. These inspection methods help ensure the quality and integrity of the steel coils before they are further processed or delivered to customers.
- Q:Can steel coils be coated with silicon?
- Yes, steel coils can be coated with silicon.
- Q:What are the common coil coating materials?
- The common coil coating materials include polyester, polyurethane, polyvinylidene fluoride (PVDF), silicone polyester, and epoxy.
- Q:- I'm considering doing my physics coursework on the uses of Mild Steel in skyscrapers and construction, would this be right? Some sources tell me mild steel is too weak, others say it is fine
- Mild steel doesn't really mean anything, technically. In today's world all steel is mild steel unless it's high carbon or alloy, which are mostly tool steels. You'll need to study steel much deeper than that to accomplish any real physics work relating to steel.
- Q:How are steel coils different from steel sheets?
- Steel coils and steel sheets are both made from the same material, steel, but they differ in terms of shape and size. Steel coils are long, continuous rolls of steel that are typically wound up into a coil shape. They are generally used for industrial purposes and can be processed further to create various products like pipes, tubes, or automotive parts. On the other hand, steel sheets are flat pieces of steel that are available in various thicknesses. They are commonly used in construction, manufacturing, and fabrication processes where a flat surface is required, such as roofing, cladding, or panels.
- Q:what are the characteristics when of iron or steel when stretched? which one could be stretched further? which one stretches more evenly?thankyou
- Technically, this is known as ductility. a material which can be permanently bent and stretched is said to be ductile. Pure iron, when it lacks carbon and impurities like sulfur and phosphorus, is relatively soft, ductile, and weak. It's about as soft as brass. It can be stretched to about 50% of it's original length before it breaks. The amount a sample can be stretched without breaking is known as elongation. The key to steel is the addition of about 2 parts per thousand of carbon, or around 0.2%. This alters the crystal structure and makes steel much harder, stronger, and tougher, though it also becomes somewhat less ductile. Mild steel, with a low carbon content, has an elongation of around 30% Adding more carbon makes the steel yet stronger, but further reduces the elongation. Adding more than 2-3% carbon produces what is known as Cast Iron. Cast iron is brittle. It has virtually no ductility. It's pretty cheap to produce though.
- Q:What are the weight ranges for steel coils?
- The weight ranges for steel coils can vary depending on the specific type and thickness of the steel. However, common weight ranges for steel coils typically range from a few hundred pounds to several thousand pounds.
- Q:How do steel coils contribute to the renewable energy equipment industry?
- Steel coils play a crucial role in the renewable energy equipment industry by being a key component in the manufacturing of various renewable energy technologies. One of the primary applications of steel coils is in the production of wind turbines. The tower, nacelle, and rotor blades of wind turbines all require steel coils for their construction. In the manufacturing of wind turbine towers, steel coils are used to fabricate the structural components that provide stability and support to the turbine. These coils are typically rolled and welded together to form the tower, ensuring its strength and durability to withstand the forces exerted by the wind. Additionally, steel coils are also used to produce the nacelle, which houses the generator and other essential components of the wind turbine. Moreover, steel coils are used in the production of rotor blades for wind turbines. These blades are responsible for capturing the wind and converting it into rotational energy. Steel coils are used to create the internal structure of the blades, providing the necessary strength and rigidity to withstand the aerodynamic forces. The coils are often combined with composite materials to optimize the performance and efficiency of the blades. Apart from wind turbines, steel coils are also used in other renewable energy technologies such as solar panels. In the manufacturing of solar panels, steel coils are used to create the frames and supporting structures that hold the photovoltaic cells in place. These frames ensure the stability and longevity of the solar panels, allowing them to efficiently capture sunlight and convert it into electricity. Overall, steel coils are vital in the renewable energy equipment industry as they provide the necessary strength, durability, and structural support to various renewable energy technologies. By enabling the production of wind turbines, solar panels, and other renewable energy equipment, steel coils contribute to the expansion and development of the renewable energy sector, thereby advancing the global transition towards cleaner and more sustainable sources of energy.
- Q:What are the dimensions of steel coils used in the energy sector?
- The dimensions of steel coils used in the energy sector can vary depending on the specific application and requirements. However, commonly used dimensions for steel coils in the energy sector range from 0.5mm to 5.0mm in thickness, with widths typically ranging from 600mm to 2000mm. The diameter of the coil can vary as well, with commonly used sizes ranging from 1000mm to 2200mm. These dimensions are chosen to ensure the coils can be easily transported, processed, and utilized in various energy sector applications such as power plants, oil and gas pipelines, and renewable energy projects. It is important to note that these dimensions are not fixed and can be customized based on specific project requirements.
