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: How are steel coils used in the manufacturing of pipes?
- Steel coils are used in the manufacturing of pipes as they provide the raw material needed for pipe production. The coils are uncoiled and then passed through a series of machines, where they are shaped, welded, and cut to the desired length and diameter. This process allows for efficient and precise pipe manufacturing, ensuring the strength and durability of the final product.
- Q: What are the different surface finishes for steel coils?
- There are several different surface finishes for steel coils, including hot rolled, cold rolled, galvanized, and coated finishes.
- Q: How are steel coils classified based on their thickness?
- Steel coils are classified based on their thickness using a gauge system, where the higher the gauge number, the thinner the coil.
- Q: Steel is no doubt a better constructin material but it is only in practice in developed country.i would like that we should high lights the benifits and negatives of steel to make the steel more clear as a construction material.Hope some expert to address this topicMD
- Steel Structure considered as the most efficient and fast in completion of any project, specially the high rise buildings, also the logistics during construction is less complicated than the normal methods, Steel Structure has so many advantages vs the disadvantages, and highly recommended for commercial buildings
- Q: How are steel coils used in the production of metal fencing?
- Steel coils are used in the production of metal fencing as they serve as the raw material for creating the wire mesh that forms the structure of the fence. The steel coils are uncoiled and then passed through a series of machines that shape and weld them into the desired fence panels or rolls. These panels are then further processed and treated to enhance their durability and resistance to corrosion, ultimately resulting in high-quality metal fencing products.
- Q: What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
- General handling steel rolls are used for driving. Forklift trucks are OK, but a larger fork truck, usually cold rolled, weighs less than 15T. The hot rolled coil is below 30T.
- 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: How are steel coils cleaned before use?
- Steel coils are typically cleaned before use through a process called pickling, which involves immersing the coils in an acid solution to remove any scale, rust, or other impurities.
- Q: What are the common uses of cold rolled steel coils?
- Cold rolled steel coils have a wide range of common uses such as in automotive manufacturing, construction, appliances, furniture, and general engineering applications.
- Q: how do i quinch steel? i heard instead of water oil will actually make it harder... wat ways are best for wat steels? and how do i tell wat kind of steel i have?... i will be doin this with my poket knife..
- boy what a though question ! let me explain. when you rapidly cool a steel from high temperatures(depending on steel type) with water or oil or other means , it is called quenching. it depends on the steel type to say if it is better to quench it with oil or water but basically in water you will have a harder steel rather than oil. for some steels if you do this you will ruin it's properties ! you can't totally tell what kind of steel do you have until you get it analyzed with Quantometer analyzer with a pocket knife it is more like an estimation and it can't be trust able generally if you can scratch the steel with your knife it means it is not a hard steel and it might not be expensive. I hope that helps but for more information i need to know more !
