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: Can cold rolled galvanized steel coils be acid washed after oxidation?
- If it has been galvanized, it can not be pickled, and if it is pickled, it may corrode the zinc layer
- Q: What are the common quality control measures for steel coils?
- Some common quality control measures for steel coils include inspection for surface defects such as scratches, dents, or unevenness, checking for dimensional accuracy and thickness consistency, testing for mechanical properties such as tensile strength and hardness, conducting chemical composition analysis, and ensuring proper packaging and labeling of the coils.
- Q: How can defects in steel coils be detected?
- Defects in steel coils can be detected through various methods such as visual inspection, non-destructive testing techniques like ultrasonic testing, magnetic particle inspection, eddy current testing, and radiographic testing. These methods help identify surface defects, internal discontinuities, cracks, or other irregularities in the steel coils.
- Q: I want to make an object out of stainless steel. Initially, I had planned to get it cut out of stainless steel sheet but several of the edges need to be rounded and I think it would be much cheaper to get it made of cast iron formed in a mold.Yet, it must be stainless steel. Can stainless steel be formed in a mold like iron can ... i.e. poured in liquid form into a mold and harden into shiny stainless steel?Would a regular foundry do this or do I need something special?Thanks.
- You have 2 options. Sand casting or investment casting. Stainless steel can be cast with either of these methods. In either case a model or pattern will have to be created. For sand casting the pattern is all that is needed to go to casting. For investment casting the pattern is used to make a wax casting, which is then coated with the investment. The wax is burned out and the metal is then poured into the cavity. If you are making just 1 or 2 pieces you can have waxes machined. This saves the intermediate step Depending on the size machining may still be your best option. Especially if you want just 1 part.
- Q: Can steel coils be transported by air?
- Yes, steel coils can be transported by air. Air freight companies have the capability to transport heavy and oversized cargo, including steel coils, using specialized aircraft and equipment. However, due to their weight and size, transporting steel coils by air can be more expensive compared to other modes of transportation such as sea or rail.
- Q: What are the different coating options for steel coils?
- There are several different coating options for steel coils, including galvanized coatings, zinc-aluminum coatings, organic coatings, and metallic coatings. Galvanized coatings involve applying a layer of zinc to the surface of the steel to provide corrosion protection. Zinc-aluminum coatings are a combination of zinc and aluminum, offering enhanced corrosion resistance and heat reflectivity. Organic coatings, such as paints or powder coatings, provide protection against corrosion as well as aesthetic appeal. Metallic coatings, like tin or chromium, offer superior corrosion resistance and are commonly used in specialized applications.
- Q: How are steel coils inspected for straightness?
- Steel coils are typically inspected for straightness using various methods such as visual inspection, laser measurement, or by passing the coils through straightening equipment.
- Q: So...that means Wolverine can stab him, right? Because Adamantite is stronger than steel. Correct?
- I don't think Wolverine could stab Superman. The name Man of Steel is just a nickname that was acquired through the years. Just like Superman is able to fly, but when the initial comic came out, he could only, leap tall buildings with a single bound, and is stronger than a locomotive. Of course, now he can fly and is MUCH more stronger than a train! hahahahah. So even though Wolverine is cool, I hardly doubt he could stab Superman...not that he would of course. =)
- Q: How are steel coils inspected?
- Steel coils are inspected using various methods such as visual inspection, ultrasonic testing, magnetic particle inspection, and eddy current testing. These techniques help identify any defects, irregularities, or damages in the steel coils, ensuring their quality and suitability for further processing or use.
- Q: What is the role of steel coils in the electrical industry?
- Steel coils play a crucial role in the electrical industry as they are used in the manufacturing of various electrical components and equipment. These coils are typically made of high-quality steel and are used in transformers, motors, generators, and other electrical devices. They provide structural support and act as a core for the electromagnetic field required for the functioning of these devices. Additionally, steel coils are also used in the production of magnetic cores, which are essential for efficient energy transfer and storage in electrical systems. Overall, steel coils are integral to the electrical industry, enabling the efficient and reliable operation of electrical equipment.
