Surface Treatment:

Chromating treatment or anti-finger print

Surface Finished:

REGULAR SPANGLE:

Regular spangle is also called normal spangle which is naturally formed without any additional treatment during galvanizing.

MINI SPANGLE:

The spangle is restrained and formed as mini spangle by reducing the lead content in the zinc liquid or by blowing the zinc powder from the equipment installed on the zinc pot.

EXTRA SMOOTH:

The mini spangle is further skin-passed to produce the extra smooth surface.

Q: How are steel coils inspected for surface quality?: Steel coils are inspected for surface quality through a visual examination process, where trained inspectors closely examine the surface of the coils for any defects or irregularities. This includes looking for scratches, dents, stains, or any other imperfections that may affect the quality of the steel. Additionally, advanced technologies such as automated scanning systems or cameras may also be used to detect and analyze any surface defects that are not easily visible to the naked eye.

Q: How are steel coils formed into specific shapes?: Steel coils are formed into specific shapes through a process known as coil slitting and coil forming. Coil slitting involves unwinding a large steel coil and passing it through a series of rotating circular blades, which cut the coil into narrower strips of the desired width. These strips are then rewound into smaller coils, known as slit coils. Once the steel has been slit into narrower strips, it can undergo coil forming to achieve specific shapes. Coil forming typically involves a combination of processes such as roll forming, stamping, bending, or pressing. Roll forming is a common method where the steel strip is passed through a series of rollers that gradually shape it into the desired profile. Each roller is designed to gradually bend the strip in a specific way, ultimately creating the desired shape. Stamping is another method used in coil forming, where the steel strip is fed through a machine that uses a die and a press to cut or shape the metal into the desired form. This process is typically used for more intricate shapes or when high precision is required. Bending and pressing are also common techniques used to form steel coils into specific shapes. Bending involves using a machine or tool to apply force and manipulate the steel strip into the desired curvature or angle. Pressing, on the other hand, involves using a hydraulic or mechanical press to exert pressure on the steel strip, causing it to be shaped according to the design of the mold or die. Overall, the formation of steel coils into specific shapes involves a combination of coil slitting and coil forming techniques. These processes, such as roll forming, stamping, bending, or pressing, allow manufacturers to transform steel coils into a wide range of shapes and profiles, catering to various applications in industries such as construction, automotive, and manufacturing.

Q: If steel content is too cheap, what content should I be looking for? I don't think I could find something like a VG-10 here...: Confusion Sucks. Why are you going into all this crap over the content of steel in the knives, your only confusing yourself. I recommend you go to a chef's supply or a good store that sells chef's utensil's and knows what he is talking about, and look at something that is comfortable for you. Chris

Q: I have heartgold and I don't have a steel type Pokemon to beat lapras. HELP: magneton. steel and electric type

Q: I'm not really sure if carbon steel is considered a metallic material.: yes its iron with carbon in it

Q: How are steel coils inspected for elongation using elongation testers?: Elongation testers are utilized to inspect steel coils for elongation, following a specific procedure. Initially, a representative sample is extracted from the steel coil, which is then prepared for testing by cutting it into a specific size and shape. Typically, the sample takes the form of a flat strip. Next, the prepared sample is inserted into the elongation tester, which comprises two clamps. One end of the sample is securely held in one clamp, while the other end is held in the other clamp. These clamps are designed to prevent any slippage during the testing process. Once the sample is securely clamped, the elongation tester applies a gradually increasing tensile force to the sample. Consequently, the sample elongates. During this elongation, the tester measures the change in length using a precision measuring instrument, like a strain gauge or an extensometer. The elongation tester records the original length of the sample before the test and continuously measures the length as the force is applied. To calculate the elongation percentage, the original length is subtracted from the final length of the sample, which is then divided by the original length. The obtained elongation value is then compared to the elongation requirements specified by industry standards or customer specifications. If the elongation falls within the acceptable range, the steel coil is considered to have passed the elongation test. On the other hand, if the elongation value exceeds the allowable limits, the steel coil might be rejected or undergo further investigation to determine the cause of elongation. Overall, the process of inspecting steel coils for elongation using elongation testers involves sampling, secure clamping, application of tensile force, length measurement, and elongation percentage calculation. This ensures that the steel coils meet the desired standards and requirements, guaranteeing their quality and mechanical properties.

Q: I expect that I will be questioned about my knowledge in methoding for steel castings, in a interview. I dont know about it. Can someone explain me in simple language and give me some links, like how I can explain methoding for steel castings.....key points...help please...so that i will pass the interview as if I have experience in methoding....thanks: It is very difficult to define Methoding of Steel castings by one sentence. Actually it encompasses the total casting process. Normally it would mean a) Pattern design i.e. what type of pattern it would be- wooden, metallic, split or full, loose or fitted on a match plate or any other, how will be the parting line. b) Design of the gating system. c) Design of risering i.e. numbers, size and location of risers. d) Design of molding process i.e. sand system to be used, mold box size. But to do justice to the above mentioned activities, you need to consider other parameters of the casting process such as chemical composition, solidification characteristics, pouring temperature, pouring time, knock out time etc. As I said Methoding of Steel castings means designing of the total casting process from inception to final product.

Q: More specifically steel wire (around 1/8 diameter). I'm doing a science fair project where I'm testing if concrete encased in steel has more fire resistance than steel by itself. However, I have no idea what the dimensions of concrete encased steel is so I can't scale down. And if I did have the dimensions I wouldn't know how to encase it around the steel wire (do I just poor concrete over it (heck I've never even used concrete)? Thanks for any help.: Yeah, just pour the concrete over it, but make sure the steel is in the middle of the concrete (I'm sure you can figure out a way to do this). What you're thinking of is called steel rebar.

Q: I'm putting a bathroom in my basement. I'm an Ironworker btw. I wanted to go with steel studs due to the fact that they are light, and I won't have a big mess. I live in the Chicago area and they should be easy to find. Here is my question. Are they not being used anymore? I ordered 100 studs from Lowe's but they didn't have track. The delivery guy was a retired Carpenter and he told me that I got all the studs they had, they no longer stock steel studs, and they don't have track. Am I missing something? Menards didn't have track either.: Steel studs are mainly for commercial applications on non bearing walls. 100 studs, must be one big assed bathroom. Do yourself a favor and install a pressure treated bottom plate, even if you use steel studs.

Q: How are steel coils used in the production of household appliances?: Steel coils are used in the production of household appliances as they serve as the primary material for manufacturing various components such as the outer body, frame, and internal structures. These coils are formed into different shapes and sizes, allowing for the creation of durable and robust appliances. The steel coils provide strength, stability, and resistance to wear and tear, ensuring the longevity and reliability of the appliances.
