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: The hard industrial steels. If there's a bunch, what's a rough average? Also, what is is measured in?
- The general purpose default steel for hard tooling applications is A2 It's cheap, readily available and comes in many different shapes and sizes. It's easy to machine soft. It's easy to harden, you can do it yourself. It is very dimensionally stable during hardening. All the steels mentioned above are specialty steels - expensive to buy, hard to work with, expensive to heat treat and dimensionally unstable during heat treat.
- Q: How are steel coils inspected for surface cleanliness during processing?
- Steel coils are inspected for surface cleanliness during processing through various methods such as visual inspection, magnetic particle inspection, and ultrasonic testing. These techniques help identify any contaminants, defects, or surface irregularities that may be present on the coils, ensuring their quality and suitability for further processing or use.
- Q: How are steel coils used in the production of roofing systems?
- The production of roofing systems involves the utilization of steel coils in various ways. Initially, the steel coils undergo unrolling and are then fed into a machine, where they are cut to the desired length for the roofing panels. Typically, these coils are composed of galvanized steel, which is coated with a layer of zinc to protect against rust and corrosion. Once the coils have been cut, they are subsequently passed through a roll-forming machine. This machine is responsible for shaping the steel into the necessary profile for the roofing panels. The specific shape of the panels may differ depending on the design and functionality of the roofing system. Following the formation of the steel, it may undergo additional processes, such as embossing or stamping, to incorporate texture or patterns onto the panels. This aids in enhancing the visual appeal of the roofing system and providing it with a distinct appearance. After the steel panels have been formed and processed, they are coated with supplementary protective layers or finishes, such as paint or polymer coatings. These coatings further augment the durability of the roofing system and offer resistance against weather elements, UV rays, and corrosion. The final step in the production of roofing systems entails the installation of the steel panels on the roof. Typically, the panels are secured to the roof structure using screws or nails. The panels are designed to interlock, ensuring a secure and watertight installation that safeguards against leaks and moisture infiltration. In conclusion, steel coils play a vital role in the production of roofing systems, providing a durable and long-lasting material that can withstand harsh environmental conditions. The versatility of steel permits various design options and customization, making it a favored choice for roofing applications.
- Q: What are the main applications of steel coils?
- The main applications of steel coils include manufacturing of automobiles, construction materials, appliances, machinery, and various industrial sectors. They are also used in the production of pipes, tubes, roofing, and packaging materials.
- Q: What are the dimensions of steel coils used in the industrial machinery industry?
- In the industrial machinery industry, the dimensions of steel coils can vary depending on the specific application and requirements. However, it is generally observed that steel coils used in this industry typically have a width ranging from 600 to 2,000 millimeters (24 to 79 inches) and a weight ranging from 2 to 25 metric tons (4,400 to 55,100 pounds). The core, or inner diameter, of the coil can range from 508 to 762 millimeters (20 to 30 inches). Furthermore, the thickness of the steel coil can range from 0.4 to 25 millimeters (0.016 to 0.98 inches). These dimensions may experience variations according to the specific needs and specifications of the machinery being manufactured or used in the industrial machinery industry.
- Q: How are steel coils inspected for defects after rewinding?
- Steel coils are inspected for defects after rewinding by using various techniques such as visual inspection, ultrasonic testing, magnetic particle inspection, and eddy current testing. These methods help identify surface irregularities, cracks, or other defects that may have occurred during the rewinding process, ensuring the quality and integrity of the steel coils.
- Q: What are the different methods of heat treatment for steel coils?
- There are several methods of heat treatment for steel coils, including annealing, quenching, tempering, normalizing, and stress relieving. Each method involves heating the steel to a specific temperature and then cooling it in a controlled manner to achieve desired properties such as increased hardness, improved strength, or reduced residual stresses. These methods can be tailored based on the specific requirements of the steel and the intended application.
- Q: for a roof spanning 14.4m x 8.4m on a residential house, is it better to use timber trusses or steel trusses? the priorities are; ease of construction, price, insulation (want to keep heat out, i am in a tropical country), durability, flexibility, minimal load on foundations.please help. thank you :-)
- U will to find details on metal trussesin constructing materials AND development through BINDRA AND ARORA and u may additionally to find them in MCKAY(B.M.C).About steel doors and windows search the net u can search in google or yahoo u will to find it . Ok bye bye all of the exceptional.
- Q: so my parents gave me stainless steel cookware for christmas and the first time i used it i cooked chicken. it stuck to the pan and where the oil splattered it cooked on and turned it dark black and brownish. and the bottom too. i don't cook with it because i don't want to burn it on anymore but i don't know how to clean it. how do i cook without burning anything, aside from a lower flame and how on earth do i get the stains on. i've tried almost everything too! thanks.
- I, too, don't like stainless steel because it is so hard to keep clean. Bar Keeper's Friend really does become your friend when you cook on stainless steel. It will remove the burnt on food, remove the dark brown stains and keep it looking new, however. And, it won't void most manufacturer's warranties on the cookware. It just takes the elbow grease to do it every time you use it. I found it is necessary to use more olive oil than you think is necessary, a lower flame than most recipes call for and a lot of patience if you plan to use it on a daily basis. I went back to my non-stick Calphelon because I am not a patient woman, I like instantaneous gratification and hate scrubbing pots and pans!
- Q: can you play one?
- Yessir. No, I can only play a piano and Guitar Hero.
