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: What is the average tensile strength of a steel coil?
- The average tensile strength of a steel coil can vary depending on the specific grade and type of steel used. However, on average, steel coils typically have a tensile strength ranging from 300 to 2,500 megapascals (MPa).
- Q: Why is iron used to create steel? Why not other elements?
- iron came before steel. iron is what was discovered that, under certain circumstances, became a stronger metal: steel. that is why. its like asking why copper is in bronze. because what we call bronze, is an alloy of copper and tin. if you give a more detailed question, i may be able to give a more detailed answer.
- Q: i need some ideas of what material could replace iron or steel to make fridges, stoves, dishwashers, tractors, aircrafts, cars and buses and anything else that is made of iron and steel. anything is greatly appreciated as at the moment i have no idea what to put down.
- at first you're able to desire to understand the elementary distinction b/w iron and steel. Iron is an ingredient on a similar time as steel is an alloy made via including an impurity carbon in very small quantity to molten style iron. 2d steel has many advantages over iron as that's immune to rusting style air and moisture, additionally it may desire to be made extra stressful via adjusting carbon content fabric. third Bronze is a steel alloy consisting mostly of copper, generally with tin because of the fact the main additive, yet each and every so often with different aspects such as phosphorus, manganese, aluminum, or silicon. So steel and iron are 2 numerous issues, one is alloy and one is ingredient. And steel and Bronze are 2 diverse alloys. steel of mostly iron and Bronze mostly of Copper. wish it helped...... stay long and prosper!
- Q: Can steel coils be used in the manufacturing of machinery and equipment?
- Machinery and equipment manufacturing can indeed utilize steel coils effectively. These coils possess remarkable versatility and contribute strength, durability, and stability to various industrial applications. They can be manipulated to assume various shapes, receive cuts, and undergo formation to generate diverse parts and components that are indispensable to the manufacturing process of machinery and equipment. Gears, shafts, frames, brackets, and other structural elements are commonly produced using steel coils. Moreover, these coils can undergo further processing to fashion specialized components like springs or fasteners. By incorporating steel coils into machinery and equipment manufacturing, the end products are guaranteed to possess exceptional quality, capable of enduring heavy loads, and boasting an extended lifespan.
- Q: i have recently gotten into DIY and am planning on making my own knife. My question is what kind of steel would be good to use for heat treating if i plan on using water and not oil in the process.
- Go to junkyard get old leaf spring, cut out knife, start sharpening. Why waste time heat treating steel when the spring steel as already be done.
- Q: Can steel coils be coated with impact-resistant materials?
- Yes, steel coils can be coated with impact-resistant materials. These coatings provide an additional layer of protection to the steel coils, making them more resistant to impact damage.
- Q: I want to know where cold formed steel framing is used, is every steel frame we see in a construction sites like houses, building and bridges cold formed steel frames? or hot formed steel framing?I also read that cold formed steel framing is used for floors, is the steel frame beneath the floor's concrete cover?Thank u very much!!
- It will vary from location to location. A possible way of telling is how the material is joined. If the material is riveted together it is likely cold rolled. If the material is welded then its probably normalized steel (possibly annealed but less likely). Cold rolling increases the yield strength of the material so less of it is needed. However, it also make the material more brittle. Welding creates defects in the region surrounding the weld and these are more likely to grow and cause failure in a cold rolled steel than a normalised or annealed steels. In addition the heat from the welding will change the microstructure that was deliberately introduced by the cold rolling process resulting in a localised drop in yield strength. Normalised and annealed steels are more ductile and tougher than Cold rolled steel but they have a lower yield strength. Because they are tough and ductile they are less sensitive to crakcs and defects so welding won't lead to as big a reduction in strength. Another possible consideration is the environment they are used in. Steels exhibit a transition temperature (actually more like a range) where they go from behaving like a ductile material to a brittle material. A well known example of what this can cause are the Liberty ships in WW2 (Supply vessels from the US to the UK). These were made by welding together sheets of cold rolled steel to form one continuous Hull. Unfortuantely the transiton temperature of the steel taht was sued was around 4 degrees while the Baltic Ocean is about 0 degrees. As a result small cracks would grow and then when the reached a critical size they would tear through the ship at the speed of sound in the metal (1500m/s) and these massive cargo ships would literally snap like twigs. So, if the steel is being used somewhere really cold its unlikely to be Cold rolled too.
- Q: i want a good modern carbon steel (not stainless) knife. trying to keep it under 50$ also nothing to gruesome just a small pocket knife. thank you
- Well, okorder /... They did make other folders in M2 steel, but the thing is those are out of production and the cost is very high. Spyderco made M4 steel folder knives, and so did Benchmade. Although,both are outside of 50$ budget. I guess Opinels are best option.
- Q: I've been looking into battle-ready katanas a lot lately. And I've come across some debates between the best forges and steels to be used for them. The functional katanas I use now are Musashi brand katanas, using 1045 carbon steel. They each cost roughly $200-$250. The straight carbon steels are mentioned in the debates, but they aren't very sophisticated in their design. Now the higher end of this middle class of katana ($250-$1000) uses higher carbon. spring, damascus, and other various steels and combinations. I've heard a lot about the strength of damascus steel and it's cutting power. But I look for more than that. I've also been looking at (and for) durability, flexibility, and how well it stands up to contact. So I guess what I'm asking is for the opinion of people who have used these steels, and an answer on what the community thinks is the best steel for a mid range ($250-$1000) battle-ready katana. Looking forward to some good answers.
- There is no such thing as a battle ready katana... if it is not ready for battle - it is not a katana. Having said that: The hardness of the cutting edge depends on the carbon content the better (in general). 1045 is poor quality steel for sword manufacture. Musashi swords are cheap pieces of crap. 1060 is better. Some manufacturers use modern materials that aren't perhaps consistent with traditional manufacture, like 9260 silicon spring steel or even L6 Bainite. Damascus steel is not a type of steel at all. It is a folding technique that creates a wavy grain in the metal. It may or may not mean that a sword is good. No swords will stand up to contact with other swords. They will inevitably be damaged. The best way to find a quality sword is to ask you instructor. There are no quality swords under a thousand dollars. The answer also depends on what you are going to do with the sword. It may also depend on the style or school of swordsmanship.
- Q: iam talking abt carbon steel of composition:-C=0.15wt% Mn=0.60wt% P=0.035wt% S=0.04wt% Cu=0.20 (min)wt%....
- The composition of the steel is almost tertiary to many other considerations, except that there are certain elements and percentages of elements which tend to affect the crystaline structure in the steel. The most basic question is whether the crystaline arrangement of atoms in the steel is martensitic or austenitic, and many factors influence that. In general, martensitic structure is magnetic and austenitic structure doesn't respond much to magnetic fields, but there are varying degrees of martensitic and austenitic -- there is never a pure state.
