Product 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. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering. 

We are specialized  in types of hot dipped galvanized, galvalume, prepainted steel products, corrugated steel sheet, etc

Q:How much pressure can concrete and steel take?
A common allowable stress for steel is 24,000 psi for A36 steel. Note that allowable stress is a working stress that is less than ultimate stress the stress at which the material will rupture. This allowable stress keeps the steel within the elastic range. Concrete allowable stress is typically around 3000 psi. Concrete, though, being a mixed material has variable values for allowable stress. Reinforced concrete design theory suggests that concrete should not be considered to be able to carry much, if any, tensile force. This explains why you will see steel rebar or reinforcing bars cast in to the concrete. The steel is there to carry any tensile forces, while the concrete is there to carry compression forces. This is a VERY basic explanation. There are entire books on both of these subjects...
Q:what came first the steel smelter/furnace or the steel used to make it?
it is a problem to work metals thats why the first furnaces were for metals with a low melting point eg copper. To built a furnace for iron you need a very high temperature and for steel additional chemical treatment probably not available on an island. To smelt iron should be possible though as a clay furnace with the right coal is hot enough to produce raw iron.
Q:Here is my dilemma, should I shoot steel case ammo in my ar15?
steel case does not cause additional wear to the gun's chamber when compared to brass case. many tests has been done and precise measurements taken, this myth has been proven false. lacquer coating can cause issues because it can melt and cool, and cause jams. this is easily remedied with a chamber brush and some solvent.. However, steel jacket causes problems. Steel is harder than copper, it does not deform as easily so it causes more wear to the barrel as compared to copper or brass. The rate is around 10-25%, inreasing if you hoot rapidly instead of slowly. more shooting = hotter barrel = faster wear. It's the same with copper/brass jackets, but steel jacketed always wears more than softer metals. TulAmmo (or tula) is particular is so cheaply made they don't have enough copper/brass wash on the bullet to survive firing, after a few inches of travel it's steel on steel contact in the bore and it can ruin a gun barrel very quickly. But... there is one exception. if your gun comes with a chrome-lined bore that is standard for most AR's , shoot all the cheap junk you can buy. chrome-lined steel is 2X as hard as plain steel. crappy tula .223 will not cause more harm to a chrome-lined bore more than brass or copper jacketed bullets.
Q:what is the diiferent in composition between mild steel and cast iron?
I know that mild steel is more brittle than cast iron You know wrong - cast iron is very brittle and mild steel is easy to bend and work. Cast iron is a high carbon product while mild steel is much lower carbon
Q:How is chrome steel made?
Go to the process section and find point 6 (explains when alloys are added). Chrome is added at this point, usually in the form of ferrochrome alloy (FeCr). Many kinds of chrome steel also contain nickel. The strengthening effect on steel by forming stable carbide grains at the grain boundaries and the strong increase in corrosion resistance made chromium an important alloying material for steel. The high speed tool steels contain between 3 and 5% chromium.
Q:Is Grade A Surgical Steel...?
Well a lot of people get microdermals done with surgical steel,yes titanium if better but it can be done with surgical steel.If you want the titanium you can always ask the piercer where they get their jewelery and if they could order them for you.You could also go to a different shop and ask if they have titanium dermals you should be able to buy them off of them.If hes an expensive piercer and your paying a lot for them you should be able to get the ones YOU want.Its YOUR body not theirs. =] hope this helped.
Q:Does mild steel rust?
Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
Q:whats the difference between weld steel and sheet metal?
Gauge is a measure of thickness. 19 Ga = 0.0418 20 Ga = 0.0359 22 Ga = 0.0299 Higher numbers are obviously thinner sheets. To my knowledge the way it works is going up five gauges means the thickness is reduced by half. For example 10 Ga. is 0.1345 in, while 15 Ga is 0.0673 in.
Q:what kind of steel is needed for bbq grill?
Steel is not good at all for BBQ grills. But Galvanized will kill you. So if you must use Steel. But for the best use cast iron grates to cook on.
Q:1 inch thick steel target good for mosin?
It sure will. It will also be a major pain in the back side to move it to where you can safely shoot at it.
