   Strapped with min three strapping strips, covered by anti-water paper and plastic film, fixed on the iron or

wooden pallets by strapping strips and covered by plastic bag to prevent damage from transportation.



C: Applications for cold rolled Steel coil:
1) For the further producing of hot dip galvanized steel products


2) Cold rolled Steel Coil: Auto manufacture, Oil drum, Transformer's tank panel, Furniture etc.

D:Process of Cold Rolled Steel Tape:
   a: Pickling: To clean the dust and rust points on the surface.


   b: Cold Rolling: Digital rolling control system produces minimum thickness tolerance, helps to prevent twist and improve straightness.


   c: Slitting: Precise slitting machinery helps control the best width tolerance and avoid camber or cracker. Also we can make round or sharp edge with additional process and special machines.


   d: Heat treatment: Advanced annealing, tempering and hardening techniques will help to produce proper mechanical property of the products to insure our client’s usage with minimum harm to natural environment.

Q: I need to identify a metal. It is rusty so I suspect it is either iron or steel. Since they both have similar densities and are magnetic, how do I tell the difference betweeen steel and iron?
Steel is a refined, alloyed metal that is mostly iron. Iron, in a chemistry sense os simply Fe. In an industrial sense iron is pig iron commonly saturated with carbon, up to 4.5% and has other impurities like sulfur. Pig iron is brittle and should break rather easily, and bend very little. After a piece is broken look at the crystal structure, you should see rather small crystals. Most steel made for car body's, washing machines, file cabinets, low grade bolts and nuts etc. should flex and bend before breaking. Most steel made for things like cutting tools, axles, etc, is hardened and will chip and break rather than bend. Also you can try to heat the piece to a glowing orange temperature. It must be very hot. Cool it. If there is a lot of white flake scale on the piece it is impure and probably iron of some sort. In the end the only way exactly tell is have an analysis done and look at the chemistry.
Q: Me and my cousin have been arguing about this. I said that superman is made out of steel, but he says that people just call him the man of steel because he's hard like steel. Does he have steel in his body?

Q: Are steel buildings or homes better then wooden buildings? Why?
Arch steel buildings are extremely easy to put up as compared to other conventional structures you don't need any type of heavy equipment to erect your steel arch buildings. Most of the people put their steel buildings up with the help of family or friends in just a couple of days.
Q: What are the common methods of cutting steel coils?
The common methods of cutting steel coils include shearing, slitting, and laser cutting. Shearing involves using a machine with two blades to cut through the coil. Slitting involves passing the coil through a set of rotating circular blades to create narrower strips. Laser cutting uses a high-powered laser beam to cut through the steel coil with precision.
Q: How are steel coils used in the manufacturing of suspension springs?
Steel coils are used in the manufacturing of suspension springs as they are wound into a specific shape and size to provide the necessary flexibility and resilience required to absorb shocks and vibrations in a vehicle's suspension system. The coils are designed to support the weight of the vehicle and provide a smooth and comfortable ride by compressing and expanding as the vehicle moves over uneven surfaces.
Q: What are the common coil slitting methods?
The common coil slitting methods include rotary shear, loop slitting, and double knife slitting.
Q: What are the common quality issues with steel coils?
Common quality issues with steel coils include surface defects such as scratches, rust, or mill scale, dimensional deviations, coil breaks or bursts, edge wave, and coil set. Other issues may include variations in chemical composition, hardness, or tensile strength, as well as improper winding or packaging, which can lead to damage or deformation during transportation or storage.
Q: How are steel coils used in the production of automotive parts?
Steel coils are used in the production of automotive parts as they serve as the primary raw material for manufacturing various components such as body panels, chassis, and structural parts. These coils are processed through different techniques like cutting, stamping, and welding to shape and form the desired parts. The strength and durability of steel make it an ideal material for automotive applications, ensuring the safety and performance of vehicles.
Q: Project for school, we're learning about periodic elements and we have to choose an item from our hobbies to research what its made of. Any ideas on steel guitar strings??
Steel is usually mainly made up of Iron (Fe) element, but it can also include Carbon (C) for a stronger steel or Nickel (Ni) for stainless steel.
Q: I mean about if I had a piece of metal, how can i decide that's iron or steel?Sorry for bad English.
Iron and steel have different thermal expansions and specific heats. You could either heat it up and see how much it changes in length or you could put it in water inside a calorimeter and observe how much the temperature of the water changes
