Product Description:

Hot-dip Zinc Coating Steel Building Roof  with Good Price Better Quality

1.Structure of Hot-Dip Galvanized Steel Sheet Description

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust.

2.Main Features of the Hot-Dip Galvanized Steel Sheet

• Excellent process capability

• Smooth and flat surface

• High strength

• Good visual effect

Q:Should I buy a guitar with nylon or steel?
Make your choice based on the type of music you intend to play. Nylon strings are used primarily for classical, flamenco and folk music. Steel strings are used for pop, rock, blues, country, folk, bluegrass.... Both types of guitar are tuned the same, so you *can* play any style of music on either guitar. The big difference is in the tone. Nylon strings are rich and full...if perhaps a little mellow. Steel strings are twangy and have a bite to the sound. There are differences in the construction and feel of the guitars, but that's not critical to your decision. Match the guitar to the music you intend to play. At 14 yrs old, you are certainly big enough for a full sized guitar....and I'll bet you're still growing, right? Even full sized guitars still vary in the size of the body. Try a few out to see how well they fit your reach.
Q:How much is 18k steel and gold worth?
Steel does not come in an 18k version and is worth only about $1.50/pound. 18k gold (.750 or 75% pure) is currently worth about $40.20/gram, based on the spot price of gold of $1,667/ounce at this moment.
Q:best folding pocket knife or best steel for them?
This Site Might Help You. RE: best folding pocket knife or best steel for them? looking for a good pocket knife. i keep going through these 440 steel pocket knives with every day work usage. this will be my 4th. even when i use a whetstone they stay sharp for a short period of time but the edge does not last, 440 is too soft! what is a good steel to look for in a pocket knife?...
Q:Is the Bianchi Pista Steel bike good?
Yes steel is a great material. It will be on the of the heavier side than aluminum depending on how well made the made the bike. I believe that steel is will definitely last a LONG time with the correct maintenance. Just keep it out of rain and every now and then strip down the bike and go through a thorough clean
Q:Steel question?
Tool steels These were designed to be used as hardenable, dimensionally stable materials for cutting of metals. The alloying elements they contain (including tungsten, vanadium, niobium and molybdenum as well as chromium)are there to produce carbides (mainly) which are stable at dull-red heat. This cannot be achieved with high carbon steels, carbide steels or (normal) alloy steels which all lose their strength and hardness at metal cutting temperatures.
Q:how to make carbon steel?
Carburized steel is not the same thing as carbon steel. All steel has carbon in it, but carbon steel is defined as Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 1.04 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. Carburizing is a surface treatment. Dropping hot steel in oil is oil quenching. It might get a little carbon in the surface, but oil quenching is mainly used as a slightly slower quenching process than water quenching, not for carburizing. Once it starts cooling down the carbon won't diffuse in. Quenching is used to change the hardness. The simplest way to carburize steel is to pack charcoal around it and heat it to 900 C or so. Industrial processes use a gas like carbon monoxide, but that's mostly just for easier process control.
Q:what are the characteristics of iron / steel?
Technically, this is known as ductility. a material which can be permanently bent and stretched is said to be ductile. Pure iron, when it lacks carbon and impurities like sulfur and phosphorus, is relatively soft, ductile, and weak. It's about as soft as brass. It can be stretched to about 50% of it's original length before it breaks. The amount a sample can be stretched without breaking is known as elongation. The key to steel is the addition of about 2 parts per thousand of carbon, or around 0.2%. This alters the crystal structure and makes steel much harder, stronger, and tougher, though it also becomes somewhat less ductile. Mild steel, with a low carbon content, has an elongation of around 30% Adding more carbon makes the steel yet stronger, but further reduces the elongation. Adding more than 2-3% carbon produces what is known as Cast Iron. Cast iron is brittle. It has virtually no ductility. It's pretty cheap to produce though.
I would go with some in one and less in the other. Given that steel prices have collapsed (and seeing as the Chinese economy is going into a recession, they will probably stay low for a while) I would say that because US Steel is a blue chip company it will be around for the long term, but, it won't make much for a while. GE on the other hand has been beaten down thanks to some mismanagement issues under current CEO Jeffrey Immelt, however, they have a range of strong products (save for their broadcast division, RCA/NBC). Given that the stock is at a severe low with the company itself being worth quite a bit (with a fair amount of bailout funds coming to its' financial division) and the Obama administrations' green initiatives coming online over the next couple of years the demand for their products will be high. I would simply say 70/20 GE/US. Good luck.
Q:Are oil and steel monopolistic competition?
While oil and steel may seem to be all the same, they are really not. There are many different grades of crude oil and many different types of steel.
Q:Can I put phosphor bronze guitar strings on an acoustic guitar with steel strings?
That's what they're meant for!
