Advantages of Our Prepainted Galvanized SteelCoil:
1) Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted Galvanizeed Steel Sheet.
2) High heat resistance: The reflective surface of the material aids in efficiently reflecting the sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity converts into energy savings.
3) Aesthetics: Pre-Painted Galvanized steel sheet is available in plethora of patterns and multiple sizes as per the requirements that given by our customers.
4) Versatility: can be used in the various areas.

Q:Can I load my own steel core ammo?
I'm a reloading trainer. This you can do - however - you are going to not be capable to re-use the powder considering the fact that you have no idea what it's, and, what the difference is between the old bullets and your new ones. As you already know - even bullets of the identical weight can have a gigantic change in stress kind one brand to one more. You're going to need to slowly work up a load, identical to a ordinary reloading load. Pulling inexpensive bullets and re-using the manufacturing unit primed case is in reality beautiful normal. I most commonly take the FN 5.7x28mm and pull the Horndy 40gr manufacturing unit - then insert the 69gr into them. The powder is discarded and i re-use those 40gr ones in my 223/5.56mm varmint gun.
Q:The difference between aluminized color steel roll and ordinary color steel roll
Substrate selection: AZ150 (aluminum zinc content 150g/m2); G345A high strength galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon) corrosion resistance data: 5%NaCL 35 DEG C, 1000Hrs, Field good, Scribe, No, Blister, 2mm belowQ.U.V: 2000hrs, MAX.2 color, light to keep the rate above 90%, the above data show that aluminum zinc coated board (AZ150, G345A, PVDF) is very suitable for the extreme environment of buildings or other facilities, highly corrosion resistance and weather resistance, and the major steel plate can ensure the service life of 20 years. In addition, high strength steel has been widely used abroad, and it has good economic performance, and it is also the domestic development trend.
Q:what type of steel is used to make rail tracks?
Hoghead has it right, it is quite mild steel, every time they try harder steel it does not stand up to the stress and breaks more readily. Rail, odd as it seems can get corrugated and rough same as a dirt road and needs to be reground from time to time to reshape the top part of the rail. Rust is not a problem on a track in use so stainless would be a unnecessary expense. Also, in high wear places, specialized welding crews come in in add new material to the most worn parts, as in switches and then regrind it to the proper profile, mild steel accepts this much better than a harder steel would.
Q:Cast iron Vs. Stainless steel?
For strength, cast iron (that's why OEM exhaust manifolds are made out of it). For performance, stainless steel. For one, stainless steel headers are lighter than cast iron ones. Then they come in multiple arrangements, (4-2-1 or 4-1 for 4 cylinder motors). The down fall is strength. Hit a pot hole with the collector of a stainless steel header. It's going to have a nice dent in it.
Q:Purchase Steel - For Construction Purpose?
I'd keep in mind whether your potential supplier is close enough to still give you good service, and provide delivery when you need it. I'd want to contact as many local companies as possible, in order to get competitive bids. Then, I'd pick the lowest cost bids that I felt would still provide the service I needed. Most decisions of this sort, in the end, are based on price.
Q:Why is steel a stiff material?
Steel is NOT stiff. In fact it is worldly accepted metals (steel is a metal) are not rigid in mechanical terms, and rigid means stiff. Steel easy to shape, but is strong and therefore hard to break. Thermosetting polymers (hard plastic) which is stiff, is in fact easy to break (weak) and also hard to reshape without changing its state (solid to liquid). Whoever told you steel is stiff is wrong and possible meant steel is strong, or you misheard/misunderstood.
Q:Why is the American steel industry failing?
Q:Does shooting steel case ammo in a AR-15 ruin/damage the gun?
No. People who say that don't use steel cased ammo. It it said its harder on the extractor. I don't see how. Its dirtier because it doesn't expand like brass does but the steel casing is still softer than the steel of the gun. That is a mild steel which isn't as hard as what most people are thinking of.
Both have advantages and disadvantages. Wood is much cheaper than steel. Wood buildings are easier to construct. Wood more easily lends itself to finishing activities (drywall and such on the interior). Wood buildings can be repaired fairly easily when damaged. Steel is stronger, and can be used for much taller buildings. Steel is more durable, it lasts longer and is more resistant to degradation. Steel is more suitable for extreme situations such as earthquakes. The cost and purpose of the building typically drive the decision regarding what material to use. For homes, its usually not feasible to use steel frames, steel just costs too much. For tall buildings, for industrial buildings, steel is used because the benefits outweight the extra cost.
Q:Hardenability of steel?
Bit tricky to explain and I don't know muh about it but steel on its own has lost of gaps in it ( the molecular structure) and when carbon is added thos gaps are filled, I think of it like this: it is easier to punch through expanded polystyrene( with all the little balls) than unexpanded(just a lump of plastic) as the balls are not properly joined and have air pockets between them.
