Product Description:

1. Hot-Dip Galvanized Steel Roof Description:

Hot-dip galvanized steel roof 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. It is especially useful for countless outdoor and industrial application.

2.Main Features of the Hot-Dip Galvanized Steel Roof:

• Excellent process capability

• Smooth and flat surface

• Workability, durability

• Excellent heat resistance performance

• High strength

• Good formability

• Good visual effect

Q:can anyone tell me were i can find strontuim steel dowel pins?
Strontium steel is created by soaking a mild steel in strontium chromate, which has a pH of about 4 or 5, roughly the equivalent of acid rain. Chromate affects the cathodic reaction, with reduction of Cr6+ to Cr3+, and the surface film was composed of magnetite and hydrated chromium hydroxide. The Strontium is a radioactive isotope. The acid bath permeates the mild steel causing it to become mildly radioactive. Simular to oil imprengation of brass and other metals. Strontium Steel has a very high value of inhibition. However due to it's radioactive properties it is not a commonly used or manufactured material. As for where to actually obtain Strontium steel dowels. I have no idea i would speculate that you would have to purchase the raw stock and have it machined into a dowel for you.
Q:what are some advantages of stainless steel?
313 times as resistant to rust and corrosion as mild steel. 30% stronger and more durable than mild steel. 15% more conductive than mild steel. Easily wiped clean. Scratches can be easily polished out.
Q:is carbon steel a good matirial for a usable sword?
Why the interest in a 'usable' sword ~~ are you really going to use it?
Q:What is the density of steel?
The short answer to your question is that the density of plain mild steel is 7.85. The long answer is that depending on where you look, or the grade of steel that you are talking about can change this value. A density of 7.88 is often quoted for mild steel as well. If you add alloying elements such as tungsten, chrome or manganese to improve the steel, the density will change. So the long answer is that the density of steel can vary between 7.75 and 8.05.
Q:Decorating stainless steel refrigerators?
Elmers, the glue maker, make stuff called Tack Adhesive Putty. It looks like a stick of kids clay or silly putty, but you tear off pieces of it and stick them to the fridge. Then stick your pictures to the putty! Works great and comes off easily.
Q:Why was there molten steel at Ground Zero?
that's just it: there wasn't very much molten steel for the very reason you point out. Jet fuel burns at 800° to 1500°F. This is not hot enough to melt structural steel. However, engineers say that for the World Trade Center towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength. Steel will lose about half its strength at 1,200 degrees F. The steel will also become distorted when heat is not a uniform temperature. after the collapse, a LOT of folks took a look at the remains. the result was the conclusion that the fire caused the central core of the building to weaken. When the floors collapsed one on top of the other, the weight was too much for the weaked core to bear, causing the result we are all familiar with. hope this helps
Q:Where can I buy sword steel?
Q:Long term effects of steel on skin?
Stainless steel contains both nickel and chromium. These two alloys are responsible for most of contact dermatitis in people. Some of my co-workers making steel had such bad reactions to chromium that they had to quit their jobs. Their skin was always inflamed. People don't react to finished stainless steel the same way because the alloys are bonded tightly in the heat treating process. But if you are grinding it and getting the dust on your skin, you could get a contact dermatitis if you are sensitive. I don't think it would absorb into your blood stream or do any long term damage to your skin. If you do get a reaction, you would have to cease your exposure or in a worse case scenario risk getting a body wide reaction like my coworkers. I would not worry about any exposure making rings out of stainless steel. After all, stainless steel is used in sugical implants and most people are fine.
Q:What is mild steel and what items are made from it?
not really. Coins aren't usually made from steel (e.g. an US cent is mainly zinc which will melt with releasing toxic fumes while welding), spoons are usually stainless steel (which is not mild steel), bottle caps can be steel but also aluminum. Fasteners can be made from a wide variety of metals. Generally mild steel is steel with a relatively low content of carbon (2%) which makes it easier to weld. It's used a lot for structure in building (e.g. rebar). Mild steel is also cheaper than other kinds of steel. Tools are usually made from high carbon steel. Generally I'd recommend to go to the scrap yard and pick up some shapes and pieces you like if you don't mind having to clean the rust off. Most will be mild steel. Welding small and thin pieces is much more challenging than welding larger pieces of metal. You are more likely to melt a bottle cap than weld it. Also your steel needs to be clean (no paint, sandblast or brush rust off). I would highly recommend to talk your project over with your teacher before you get all frustrated.
Q:Steel Estimating Question?
It is not clear what stage this project is in. Is it preliminary or has a detailed design been done. It is also not clear if this is only the steel material or does it include the labor as well. A rough guess using a percentage of the total cost is okay if you have historical data to help you. If you have a detailed design then the percentage method should only be used as a check on a detailed cost estimate developed from the plans. If you plan to use numbers provided by someone here on Answers I would hardly call that an estimate.
