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:I thought it was STAINLESS STEEL! I have stainless steel can openers spatulas that are rusty. What's up with that? did you know that braces on people's teeth are made of stainless steel? That's why they call people metal-mouth. I used to have braces.
- steel is a iron alloy with composites like carbon and with a minimum chromium percentage of 10.5 ...and the strength and other properties are closely related to the percentage of carbon and chromium used in it..! its the chromium that creates a thin oxide layer maintaining the lustre by preventing the alloy from forming the iron oxide which is often reffered as rust..so if you got your stainless steel rusted you are betryed by the manufactures and may be they have failed to anticipate the sorrounding environment so that they selected a compostion that best suits..!! cheers..!
- Q:Theirs this two handed chinese sword on amazon with a forged combat steel blade and i was wandering if it means combat steel in the same sense that tempered carbon steel can be used?
- Combat steel? No such thing... Combat steel is a commercial product... not a true type of steel, since there is no ASTM grade of combat steel... And carbon steel is a WHOLE list of different types of steel, whether it's tempered or not... The company does not provide what steel specifications it has other than combat steel... So my best guess is that it's an alloy of 1095 or 301 spring tempered... both are resilient to snapping and fatigue, and common in modern swords... however, they do not hold an edge very well and are prone to rusting...
- Q:How are steel coils inspected for elongation using elongation testers?
- Steel coils are inspected for elongation using elongation testers by following a specific procedure. First, a representative sample is taken from the steel coil, which is then prepared for testing by cutting it into a specific size and shape. The sample is usually in the form of a flat strip. The prepared sample is then placed into the elongation tester, which consists of two clamps. One end of the sample is securely held in one clamp, while the other end is held in the other clamp. The clamps are designed to prevent any slippage during the testing process. Once the sample is properly clamped, the elongation tester applies a tensile force to the sample. This force gradually increases, causing the sample to elongate. As the sample elongates, the tester measures the change in length using a precision measuring instrument, such as a strain gauge or an extensometer. The elongation tester records the original length of the sample before the test and continuously measures the length as the force is applied. The elongation is calculated by subtracting the original length from the final length of the sample and then dividing it by the original length. This gives the percentage of elongation. The obtained elongation value is compared to the specified elongation requirements set by industry standards or customer specifications. If the elongation falls within the acceptable range, the steel coil is deemed to have passed the elongation test. If the elongation value exceeds the allowable limits, the steel coil may be rejected or undergo further investigation to determine the cause of elongation. Overall, the process of inspecting steel coils for elongation using elongation testers involves taking representative samples, clamping them securely, applying a tensile force, measuring the change in length, and calculating the percentage of elongation. This helps ensure the quality and mechanical properties of the steel coils, thereby meeting the desired standards and requirements.
- Q:Can steel coils be stamped?
- Yes, steel coils can be stamped.
- Q:How are steel coils inspected for surface quality?
- Steel coils are inspected for surface quality through a visual examination process, where trained inspectors closely examine the surface of the coils for any defects or irregularities. This includes looking for scratches, dents, stains, or any other imperfections that may affect the quality of the steel. Additionally, advanced technologies such as automated scanning systems or cameras may also be used to detect and analyze any surface defects that are not easily visible to the naked eye.

- Q:What are the different types of steel coil coatings for corrosion resistance?
- There are several different types of steel coil coatings that are specifically designed to provide corrosion resistance. These coatings can be categorized into two main types: organic coatings and metallic coatings. 1. Organic Coatings: - Polyester: Polyester coatings are commonly used for steel coil applications due to their excellent corrosion resistance and durability. They offer good weatherability and resistance to chemicals, making them suitable for outdoor applications. - Polyvinylidene Fluoride (PVDF): PVDF coatings are highly resistant to UV radiation, weathering, and chemicals. They provide exceptional durability and are often used in demanding environments such as coastal areas or industrial settings. - Polyurethane: Polyurethane coatings offer excellent abrasion resistance and provide a high level of corrosion protection. They are commonly used in applications where there is a higher risk of mechanical damage or exposure to harsh conditions. - Epoxy: Epoxy coatings provide excellent adhesion and chemical resistance. They are often used in industrial applications where resistance to chemicals, solvents, and oils is required. 2. Metallic Coatings: - Galvanized Coatings: Galvanized coatings involve applying a layer of zinc to the steel surface through a hot-dip or electroplating process. This creates a barrier between the steel and the surrounding environment, providing effective corrosion protection. Galvanized coatings are widely used in various industries due to their cost-effectiveness and good durability. - Galvannealed Coatings: Galvannealed coatings are similar to galvanized coatings but undergo an additional heat treatment process. This results in a coating with increased hardness and improved paint adhesion, making it suitable for applications that require additional surface protection or paintability. It is important to consider the specific requirements of the application and the level of corrosion resistance needed when selecting the appropriate steel coil coating. Consulting with coating manufacturers or industry experts can help determine the most suitable coating for a particular application.
- Q:steel strutural
- Yes, it is classified for General structural purposes
- Q:If a make a dish antenna of steel and of fiberglass, which would be more heavy and also which would be more expensive?
- Why not go one better. An aluminum mesh would be lighter than both for the same size and would not need to be painted. It would probably be more expensive than the steel however.
