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: Have spent two days making a specialized knife out of 304 stainless steel, after throwing into a log it bent slightly arghhhh. Is it worth continuing to finish it off or start all over again with different kind of steel if so which kind should i use.
- Sorry okorder /... I hope that link works but as you can see you dont want to use 303.304.316,410,416,430 You can get away with 301 but would be best to use 440. It kind of sounds like your a home shop guy. It would be best for you to make a knife out of a1 or d2 tool steel. with these steels you can torch heat them to a red hot heat where a magnet will not stick to them. Then let them cool slowly in the air. After that you can temper in a oven around 400f. This will a very hard long lasting knife. Check OKorder for good steel prices. A1 and D2 are not stainless but they are the best for a home shop. If you go stainless you can buy preharden material but you will have to grind everything. You can also pay someone to harden your knife but dont plan on it being cheap.
- Q: Can steel coils be coated with thermally conductive materials?
- Yes, steel coils can be coated with thermally conductive materials. These coatings, such as thermally conductive paints or ceramic coatings, are designed to enhance heat transfer properties and improve the thermal conductivity of the steel coils. This can be beneficial in various applications where efficient heat dissipation or thermal management is required.
- Q: How are steel coils used in the production of steel plates?
- Steel coils are a critical component in the production of steel plates. They serve as the primary raw material for manufacturing steel plates. The process begins with the production of steel coils, which are created by heating and cooling molten steel to form thin, flat strips. These coils are then processed further in a rolling mill, where they are passed through a series of rollers to reduce their thickness and increase their length. Once the desired dimensions are achieved, the steel coils are then uncoiled and straightened. This process involves feeding the coils through a machine that removes any curvature or deformities, ensuring the strips are completely flat. The straightened coils are then cut into specific lengths to suit the required dimensions of the steel plates. After being cut, the coils undergo another crucial step known as leveling. This process involves passing the strips through a leveling machine, which eliminates any residual stress or warping that may have occurred during the production process. Leveling ensures that the steel plates have a uniform thickness and are free from any distortions, making them suitable for various applications. Once the leveling process is complete, the steel coils are finally transformed into steel plates. These plates can be further processed based on the desired end-use. They may undergo additional treatments such as heat treatment, surface finishing, or coating to enhance their strength, durability, and corrosion resistance. In summary, steel coils are the starting point for the production of steel plates. They undergo several crucial steps, including rolling, uncoiling, straightening, cutting, and leveling, to transform them into flat, uniform steel plates. These plates can then be further processed and customized for a wide range of applications in industries such as construction, automotive, shipbuilding, and manufacturing.
- Q: Can one assume that stainless steel that can be hardened is magnetic?
- All steels are hardenable if you use the right process. Most stainless steels are magnetic but usually more weakly than mild steel.
- 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.
