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: What are the different coil leveling machine configurations used for steel coils?
- There are several different coil leveling machine configurations used for steel coils, depending on the specific requirements of the application. Some common configurations include single-leveler machines, which use a set of leveling rollers to reduce the coil's thickness variations; double-leveler machines, which employ two sets of leveling rollers for enhanced precision; and stretch leveling machines, which utilize a combination of roller leveling and tension to remove coil shape defects. These configurations can be further customized with additional features such as coil feeders, crop shears, or edge trimmers, depending on the desired end product and production requirements.
- Q: How are steel coils used in the manufacturing of agricultural silos?
- Steel coils are used in the manufacturing of agricultural silos to create the cylindrical structure of the silo. These coils are rolled and shaped into large, seamless rings that form the walls of the silo. The coils provide strength and durability to withstand the weight of the stored grain or other agricultural products, ensuring the structural integrity of the silo.
- Q: How are steel coils used in the production of building systems?
- Steel coils are used in the production of building systems by being processed and shaped into various components such as beams, columns, and trusses. These coils are fed into machines that cut, bend, and mold them into the desired shapes, providing structural support and stability to the building.
- Q: What are the safety regulations for handling steel coils?
- The safety regulations for handling steel coils typically include wearing appropriate personal protective equipment (PPE), such as gloves, safety glasses, and steel-toed boots. Additionally, workers are often required to receive proper training on safe lifting techniques and use of equipment, as well as understanding the weight and dimensions of the coils being handled. It is important to ensure a clear and organized work area, secure stacking and storage practices, and the use of appropriate lifting equipment, such as cranes or forklifts, to minimize the risk of accidents, injuries, and damage to the coils or surrounding infrastructure.
- Q: What are the different types of steel coils?
- There are several different types of steel coils, including hot rolled coils, cold rolled coils, galvanized coils, and stainless steel coils.
- Q: I Don't have a Oxy act. torch but can Get a Propane one. The finished part(s) are .375 x .550 x .185
- I think 12L14 is NOT heat hardenable, because it is low-carbon. You may try heating and quenching it, but it won't harden much. It can be hardened by cold-working - drawing or rolling processes. However, these are usually done by the material manufactures, and most machine shops do not have the capability to do this in house. Can you try 1144 steel instead? 1144 is medium-carbon (0.44%), and heat treatable. It is also free machining grade like 12L14. Other medium carbon steels are also heat hardenable: 1040, 1050, etc.
- Q: How are steel coils used in the production of electronic devices?
- Steel coils are used in the production of electronic devices for various purposes, such as creating magnetic fields, providing structural support, and acting as conductors in transformers and inductors. These coils are typically wound around a core material, such as ferrite or laminated iron, to enhance their magnetic properties and improve their performance in electronic circuits.
- Q: What are the common thicknesses available for steel coils?
- The common thicknesses available for steel coils depend on the specific requirements and applications. However, there are some standard thicknesses that are commonly produced and used in various industries. Generally, steel coils can have thicknesses ranging from 0.005 inches to 0.5 inches or even more, depending on the type of steel and its intended use. For example, in automotive manufacturing, where steel coils are used for body panels and structural components, the common thicknesses can range from 0.5 mm (0.020 inches) to 3 mm (0.118 inches). In the construction industry, where steel coils are utilized for roofing, siding, and structural framing, the common thicknesses can vary from 0.014 inches to 0.062 inches, depending on the specific application and structural requirements. Similarly, in the manufacturing of appliances, such as refrigerators, washing machines, or HVAC systems, steel coils with thicknesses ranging from 0.018 inches to 0.035 inches are frequently used. It is worth noting that these are just some of the common thicknesses, and there can be variations based on the specific requirements of different industries and applications. Additionally, custom thicknesses can also be produced upon request to meet unique needs in various sectors.
- Q: Can steel coils be coated with zinc-nickel alloy?
- Yes, steel coils can be coated with zinc-nickel alloy.
- Q: hi i was doing a little history project on guns. i was just wondering if anyone could help me find out what material was used before steel and why this material wasnt as good as steel ( its faults)thanks for your help
- The most common was bronze, which was the strongest material that could be cast, at least until the industrial revolution. Until that time, furnaces which could reach temperatures hot enough to melt steel did not exist. The only way to work with steel would have been forging, which means hammering it into shape while red-rot. Obviously, this is not a very practical method for making large thick-walled cannons (though it was done on occasion. Small arms such as pistols and muskets could be easily made of steel by hand forging.) The most practical way to make cannons was pouring molten bronze which melts at significantly lower temperature than steel. Cast iron was also used. Note that Cast Iron contains 3%-7% carbon, compared to steel which only contains between 2% to 0.2% carbon. Due to the excessive carbon content of cast iron, it's melting point is about 500 degrees lower than steel enabling it to be melted with pre-industrial furnaces. Unfortunately, cast iron is also brittle, unlike steel or bronze. This means that a defective or cracked casting could easily explode, sending iron shrapnel everywhere. (Also, maiming and killing the gun crew, an experienced gun crew was as valuable as the cannon itself!) For this reason. Cast iron cannon were usually considered a cheap, risky alternative to expensive but durable bronze.
