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 types of steel coil storage racks?
- There are several different types of steel coil storage racks, including coil cradles, coil saddles, coil blocks, and coil storage bins. Each type is designed to safely and efficiently store steel coils based on their size, weight, and specific requirements.
- Q: what are the properties that can strengthen the steel to withstand earhquake?
- Well, its not necessary how strong steel is but how buildings are designed that withstands earthquakes. Steel as a property has to elastic qualities and when earthquakes are initiated but moving of the plates, the building has to absorbed the effects of the earth movements while remain standing. This does not necessary mean that the building will be usable afterward but it has to remain standing. Now, how does a building remain standing? All building have within its design a VLLRS (vertical lateral load resisting system). This system is basically designed to resist earthquake loads as well as wind loads. In steel buildings, this system is usual made of OMF (Ordinary moment frames) or braced frames. These frames act to absorb the lateral loads and transmit them into the foundation below. If the structure was concrete, there would still be moment frames made of concrete and steel but you know that concrete has a elasticity that is less than steel. ALthough there elasticity is less, they are stiffer and concrete structure tend to resist more lateral load because of it. In concrete, we can create shear walls which are basically walls that are thick and wide to resist lateral load from earthquake and wind. Masonry has even a lesser strength than steel or concrete and wood even less than above. What makes them usful is how they are used to resist earthquake loads or lateral loads from earthquake and wind. So, to answer your question, its not nessary how strong the steel is but how the material is used to resist earthquake is what is important.
- Q: How are steel coils used in the manufacturing of construction excavators?
- Steel coils are often used in the manufacturing of construction excavators to form the structural components and body parts. These coils are cut, shaped, and welded to create the framework, bucket, and other essential components of the excavator. The high strength and durability of steel make it an ideal material for supporting heavy loads and withstanding the demanding conditions of construction sites.
- Q: During fatigue testing of any material (especially for steels), why is strain-control mode preferred over stress control mode?
- because metals, like steel, are ductile and will stretch before breaking. Straining the metal is stretching it, stressing the metal is applying a shearing force or bending until there is an actual metal failure. A sheet metal strap 1inch across and 24 gauge metal is commonly used to support metal ducting systems in construction. These have an average strain to failure weight load as high as 16,200 lbs. As reported by the smacna index, they will safely hold 6800 pounds. Of more interest is the screws used to hold the strap to the duct. While they are grade 3, fairly strong, they strain to 1400 pounds when properly installed, and are safely able to support 650 pounds, unless they are overtorqued (stripped) and this quickly drops to 400 pounds and 125 pounds...big difference.
- Q: How are steel coils used in the manufacturing of railway tracks?
- Steel coils are used in the manufacturing of railway tracks to produce high-quality and durable rails. These coils are unwound and undergo a series of processes such as rolling, heating, and shaping to form long, straight sections of rail tracks. The steel coils provide the necessary strength and flexibility required to withstand the heavy loads and constant stress of trains running on the tracks.
- Q: I am trying to make a homemade fender eliminator for my motorcycle and the instructions from the site I found said to use 22 gage weld steel. I went to lowes and all they had was 26 gage sheet metal. What is the difference between the two? Is weld steel less flexible?
- Most sheet metal is coated with galvanizing. Not fun to weld on. Most steel for welding use is just carbon steel.
- Q: Can steel coils be coated with light-reflective materials?
- Yes, steel coils can be coated with light-reflective materials.
- Q: Just two sentences on a detailed description on what the steel industry is
- The steel industry is an industry that produces steel. It is one of the largest industries in the world, with China as the leading steel producer
- Q: How are steel coils used in the manufacturing of renewable energy equipment?
- Steel coils are used in the manufacturing of renewable energy equipment as they serve as a crucial component for structural support and durability. These coils are often used to construct the frames and structures of wind turbines, solar panels, and other renewable energy equipment. Additionally, steel coils are used for the production of electrical transformers and generators, which are vital for converting renewable energy sources into usable electricity.
- Q: A steel rod AISI 1040 has the ultimate tensile strength Sut of 113 kpsi. Determine the rotating bending specimen's endurance limit S'e at 10 to the 6th cycles.
- A rule of thumb for endurance limits of steel with Sut 200 ksi is that S'e = 0.504 x Sut, thus for your case that would be 113 x .504 = 56.95 ksi (endurance limit is defined as fatigue life greater than 10^6 cycles)
