Product Description:

1. Pre-Painted Galvanized/Aluzinc Steel Roof Description:

With GI as base material, after pretreatment (degrease and chemical treatment ) and liquid dope with several layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized (aluzinc) steel. Pre-painted galvanized roof is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.

2.Main Features of the Pre-Painted Galvanized/Aluzinc Steel Roof:

• Excellent process capability

• Smooth and flat surface

• Workability, durability

• Excellent heat resistance performance

• High strength

• Good formability

• Good visual effect

Q:why does steel have a density range when other metals do not?
Steel is not a pure element it is an alloy. Steel is primarily iron but it has many elements blended in that change it's density including carbon,silicon, nickel, chrome, etc. Aluminum and copper , magnesium and so forth can be the pure element or they can be alloys too. If they are alloys, then their densities vary also
Q:What is better carbon steel or stainless steel for a knife?
The better grade of stainless is the top choice, but it can be hard to find, and expensive. - Surgical scalpels are made of it. (Common '420' stainless will not hold an edge as well as high carbon steel.)
Q:Magnet will not stick to stainless steel?
That's interesting that it caused deflection in the compass. A lot of stainless steels may be SLIGHTLY magnetic, because they have small amounts of ferrite or alpha-iron in them. Ferrite is one of the crystal phases of steel. It has a body-centered cubic (BCC) structure and it's responsible for the magnetism of ordinary steels. Adding certain elements like nickel, manganese, or molybdenum, changes the crystal structure of the steel to a face-centered cubic (FCC) structure, which is NOT magnetic. This crystal phase is known as Austenite or gamma-iron. However most iron alloys contain some impurities that may cause the steel to be not completely transformed into the FCC austenite phase, small areas remain as ferrite.
Q:What sort of Steel should I use?
Sprinkler pipe or black pipe. Designed for fire suppression systems, it is often used for coping on skateboard and BMX fixtures. Not sure of the price, you could probably pick up some scrap from a plumbing supply house or a sprinkler installer. Can't imagine the cost to be more than $10
Q:What's the process of making steel?
I believe you are asking about two vastly different processes. This is science so, if you want a specific answer, you have to ask specific questions. VERY Basically... 1) Pig iron production works by melting iron and pouring it into molds that produce ingots called pigs. 2) fraction distillation separates different substances (typically starting in liquid form) by controlled heating so, since different substances boil at different temperatures, the vapors can be captured selectively.
Q:Does cold steel of kershaw make better knives?
Cold Steel uses an incredible quality of metal. If you want very durable go with that. The benefit to Kershaw is they make better folders. Fixed blade--go with Cold Steel. Folder, go with Kershaw. I get all my knives from the guys below, they have free shipping and really good prices.
Q:who would buy shredded scrap steel in GTA?
We are one of the biggest steel mills in Asia. Under our group, we have steel mills in Thailand and Bangladesh. On the monthly basis, we purchase steel scrap HMS1/2 80:20 and the shredded ISRI210/211, ISRI211 by bulk and 20' container to Thailand and Bangladesh. Due to the limitation of our existing shredded steel scrap supplier, we need to get more supply of the shredded. Please contact us or offer us of ISRI 210/211 or ISRI211 CFR Chittagong, Bangladesh with 500mt - 2000mt per shipment by 20' container. If any questions, please feel free to contact us.
Q:Why aren't bullets made of steel?
Well trying to force that down a rifled barrel would be a funny trick. Please have a friend or two there to record it so they can put the blowing up of your rifle on youtube so people can learn what happens when idiots try stupid things. I'd say you should but you'll likely be dead or in hospital from the injuries. To expand your knowledge: Until you get to NIJ class 3 body armor any lead core high velocity bullet of FMJ form will go through like it's not even there. Oh pretty much anything with soft point ammunition at over 2,000fps velocity will go through with devastating effect. So lets see .. oh yes time to ban the .30-30 Winchester for civilian use. All the typical rifle caliber ammunition designated by the military as armor piercing has a copper alloy jacket around either a hardened steel core or more commonly a lead core with a hardened steel or tungsten alloy penetrator centered in that.
Q:Fire resistant steel?
There is a chemical that is used presently that is sprayed onto steel beams called Monocoat. Its a form of insulation that gives steel protection for up to 2 hours I think. Hope that helps!
Q:What minerals are mixed to make steel?
Carbon and Iron.....usually.
