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.
5.Others:vending machine; game machine; etc.

- Q: How are steel coils used in the HVAC industry?
- Steel coils are commonly used in the HVAC industry for heat transfer purposes. They are typically used in air conditioning and refrigeration systems to transfer heat between the refrigerant and the surrounding air. The coils are designed to efficiently absorb or release thermal energy, allowing for effective cooling or heating.
- Q: Can steel coils be customized in terms of size and shape?
- Yes, steel coils can be customized in terms of size and shape.
- Q: I'm doing a commercial for chemistry and I need to know any kind of chemistry dealing with Callaway Big Bertha Irons. I know they are stainless steel but any more info would help out! Thank you! :)
- Stainless steel is a mixture of metals, each metal is included in order to make up for each others weaknesses. Each metal is included due to a property that is benificial in some way, for instance Chromium is included because it makes the stainless steel 'stainless'. In chemistry a mixture of metals, stainless steel, is called an alloy.
- Q: What is the average amount carbon emissions of steel per pound produced?
- Carbon okorder /... - Similar pages - Life-cycle energy and emissions of marine energy devices | Carbon ...Carbon dioxide emissions per unit mass of steel: 1.75 tCO2/tonne steel ; Total mass of steel in device: 665 tonnes ; Carbon dioxide emissions due to .
- Q: How do steel coils contribute to the manufacturing of appliances?
- Steel coils are used in the manufacturing of appliances as they serve as a primary raw material for various components such as frames, panels, and structures. These coils are processed and shaped into different forms to meet the specific requirements of different appliances. Additionally, steel coils provide durability, strength, and corrosion resistance to appliances, ensuring their long lifespan and high-quality performance.
- Q: Can steel coils be galvanized?
- Yes, steel coils can be galvanized. Galvanizing is a process of applying a protective zinc coating to steel to prevent corrosion and increase its durability. Steel coils are commonly galvanized to enhance their resistance to rust and other forms of corrosion.
- Q: So I'm looking for some decently priced black motorcycle boots that have steel toes (and any additional protection) and look good in jeans. Pretty simple. Any recommendations?
- (add boots in top right search) If your looking for a dedicated motorcycle boot they have videos (top of line look for the high $) what they don't tell you is the added road feedback threw the soles and the small wear toe hard shift pad gives you feed back on the shift lever next to bare footed!
- Q: How do steel coil manufacturers ensure fair pricing?
- Steel coil manufacturers ensure fair pricing through various measures. Firstly, they conduct thorough market research to understand the current industry trends, demand-supply dynamics, and competitor pricing. This helps them determine a competitive yet fair pricing strategy that aligns with market standards. Secondly, steel coil manufacturers consider the cost of raw materials, production, and operational expenses to determine a reasonable base price. They also factor in economies of scale, as larger production volumes can lead to lower costs per unit. Additionally, steel coil manufacturers often establish long-term partnerships with suppliers to ensure a stable and consistent supply of raw materials at fair prices. This allows them to maintain a reasonable cost structure and minimize price fluctuations. Furthermore, these manufacturers strive for transparency in pricing by providing detailed quotations that break down the cost components. This helps customers understand the factors contributing to the final price and ensures fairness in the pricing process. To enhance fairness, steel coil manufacturers also consider the specific requirements of their customers. They may offer customized pricing based on factors such as order volume, delivery timelines, and value-added services. This approach ensures that each customer receives a price that is commensurate with their unique needs and requirements. Overall, steel coil manufacturers ensure fair pricing by conducting market research, considering cost factors, maintaining transparent pricing practices, and offering customized pricing options. By doing so, they aim to create a fair and mutually beneficial pricing environment for both themselves and their customers.
- Q: How are steel coils used in the manufacturing of renewable energy equipment?
- Steel coils are used in the manufacturing of renewable energy equipment to form the structural components, such as frames and supports, as well as to create the outer casing and housing for various renewable energy devices, including wind turbines, solar panels, and hydropower systems. The strength and durability of steel coils make them essential for ensuring the stability and longevity of these equipment, enabling them to withstand harsh weather conditions and operate efficiently for years.
- Q: What are the different methods of pickling steel coils?
- There are several methods of pickling steel coils, including acid pickling, electrolytic pickling, and mechanical pickling. Acid pickling involves immersing the coils in a bath of diluted acid, such as sulfuric acid or hydrochloric acid, to remove surface oxides and impurities. Electrolytic pickling uses an electric current to remove the oxide layer from the steel coils, usually in a solution of sulfuric acid. Mechanical pickling involves scrubbing the coils with abrasive materials or using mechanical rollers to remove the scale and impurities. Each method has its own advantages and is chosen based on the specific requirements and conditions of the steel coils.
