steel bridges that have been made of wood lasted way longer than steel bridges NOT true. Why do you think bridges are made from steel or concrete, and not wood? wood rots and splinters and doesn't last more than 10 years when exposed to the weather. .
Q:Is Galvanized Steel a raw material?
As a specially coated type of steel, galvanized metal enjoys a great reputation as being an ideal building product to use for any type of structure that is expected to stand for many years. Here are some basics about how galvanized steel is created, as well as how it can be used in various building projects. Galvanized metal is simply steel in some form that has received a thin coating of zinc oxide. The purpose of the zinc is to protect the steel from elements that normally would lead to oxidation, corrosion and the eventual weakening of the steel. In this sense, the zinc coating acts as what is called a sacrificial anode. In other words, the zinc will protect the steel from corrosion by acting as a barrier between the steel and the corrosive agent, at least until the zinc coating has been completely oxidized. Galvanized metal can be made into supports, girders and even into sheets of metal that can be used in all sorts of construction and building projects.
Q:how to tell if its stainless steel?
Stainless steel should be non-magnetic.
Q:Why is brass ammo considered superior to steel cased ammo?
Ok folks, BOTH Brass and Steel work harden. That's what happens when you get into the plastic deformation part of the stress - strain curve. In the case of brass it can take significantly more deformation before it hardens than steel, steel can take significantly more stress before it goes into plastic deformation. Steel is unattractive in plastic strain environments because it has an unstable plastic deformation region before it stress hardens. Brass has much smoother performance. I don't know a heck of alot about making casings, but certainly for necked casings steel will wear out tooling much faster than brass. In a straight wall case it probably doesn't matter as much since it is just tubing. Typical Brass has a brinnell hardness of around 60, mild steel around 130. Steel is a LOT harder than Brass.

Q:Which wheels are better? Steel? or Aluminum? and Why?
If you got money to waste get the aluminum. Practicality is the steel wheels.
Q:What is better carbon steel or stainless steel for a knife?
Are you going to use it and take care of it? All butchers use the high carbon steel blades. If you want something to shine real pretty then go with the stainless.
Q:Why can't the coil weight be too low?
And may make the level stacked steel coil collapse, rolling, produce production safety accidents.
Q:why use steel-reinforced concrete?
Pre stressed concrete is held in compression by the steel cables within.
Q:What is the difference between steel and fiberglass entry doors?
Fiberglass doors insulate better than the steel doors and they do not dent or rust. Go with fiberglass.
Q:How to solve steel plate storage
According to the principle of "first in first out" to carry out the turnover, organize the logistics, reduce the large amount of moving plate, reasonable arrangement, easy to steel coil into the use of state.
