Structure of Aluminum Zinc Rolled Coil

 Prepainted Rolled steel Coil for Construction Roof

Description of Aluminum Zinc Rolled Coil
Aluminum zinc coils 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.

Q: I have one and wonder how much force this can take since it does seem like you can bend it(Sure it's impossible with hands), but I don't want to try that cause i don't want to break it. Many people say that it's really hard and can handle a hammer smash? is that true and can it even make it through more force. Cause steel is harder than iron and iron is pretty hard... So how much can i trust this locks security, i mean if i put at at a door would some thiefes be able to break it, if they had the right tools??
It's hard to give you a quantitative answer. There are different grades of testing standards for padlocks. It comes under the ASTM F883. You need to be more specific. The link only gives a picture and no details about the lock. But in general, stainless steel locks are pretty darn strong. Also, you are under the wrong impression about steel vs iron. Iron is a component of steel. Pure iron is very ductile and is softer than steel. Cast iron, is very hard, but is also very brittle and has limited uses. In general, mild steel is realitively soft and ductile. But, there are many different alloys of steel and some have hardnesses and strengths higher than cast iron. Stainless steel is typically more ductile that mild steel because of the smaller amount of iron in the recipe. There are exceptions to that as well. The 400 series of stainless steels have higher amounts of iron and can be heat treated to hardnesses equaling the better steel alloys.
Q: Hi All,I was wanting to know,on the quality bikes such as Trek,Giant etc is the aluminum frames as strong as the steel frame bikes? I have heard conflicting reports on this,so thought I would ask here for more input.Thanks!
Dustin You are close, but not quite right. Steel is a great frame material, It can be heavier than its aluminum counter part, But, steel often provides a much nicer ride. Aluminum tends to be a very stiff and rigid ride that many do not like. I have had frames made of all materials. I can say that I have never met a frame material that I did not like. Check the weight of the frames you are looking at. If there is more than two pound (or so) difference then the aluminum frame would be my choice. Soccerref
Q: How are steel coils processed for specific applications?
Steel coils go through a series of meticulously planned steps to be processed for specific applications. The process commences with the selection of the appropriate steel grade and thickness, which is based on the requirements of the end application. Upon receiving the steel coils, they undergo a series of processing steps to transform them into the desired product. The first step in processing steel coils is referred to as uncoiling, where the coil is unwound and straightened to ensure it is flat and ready for further processing. Next, the uncoiled steel is cleaned to eliminate any dirt, oil, or rust on the surface. This is typically done through pickling, a process that involves immersing the steel in an acid bath to remove impurities. Once cleaned, the steel undergoes various shaping processes depending on the desired application. This can involve slitting, where the coil is cut into narrower strips, or shearing, where it is cut into specific lengths. These shaping processes often require specialized machinery capable of handling the high strength and thickness of the steel. After shaping, the steel may undergo additional processes to enhance its properties. For instance, it can be heat treated to increase strength or hardness, or it can go through a coating process to improve corrosion resistance. Coating techniques can include galvanizing, where a layer of zinc is applied to the steel, or painting, where a layer of paint is added. Finally, the processed steel coils are inspected for quality and undergo any necessary finishing processes. This can involve trimming the edges to remove irregularities, or applying protective coatings to prevent damage during transportation or storage. In conclusion, processing steel coils for specific applications is a complex and carefully controlled process. It involves a combination of shaping, cleaning, coating, and finishing processes to ensure that the steel meets required specifications and is suitable for use in various industries such as automotive, construction, and manufacturing.

Q: I work at a tool store. I told my boss last week we needed more pruning shears so he did get more of all kinds. Thing is out of all of the shears he brought Two of different kinds say they are made out of Japanese steel. I have never heard of Japanese steel so now i ask you (the public) whats the difference between it and steel from the US or any other country? Those shears are worth more then the ones he gets from Mexico and China and even more than Black and Decker, Fiskars, etc but not more then Corona brand ones.
Well Japan, with democracy and code standards, would be better than China or Mexico, with poorly paid workers and poor standards and poor quality. I don't know why or if its better quality than US steel
Q: How are steel coils used in the production of metal roofing panels?
Steel coils are a critical component in the production of metal roofing panels. These coils, which are rolled sheets of steel, play a crucial role in shaping and forming the panels. To start with, the steel coils are unwound and fed into a machine called a roll former.
