1.FAQ of Pre-Painted Galvanized/Aluzinc Steel Roof

What’s the brand of the paint?

We use the best brand of all of the word—AKZO.

What’s the wet and heat resistance of the roof?

More than 1000 hours.



2. 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.

3.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:Engineering Materials - tool steel question?
It all depends what the application actually is. For hammers I would select a hammer grade B1 steel. For impact loading where an edge is needed I would be going for O1 or similar (oil quenching steels tend to be a little tougher than air hardening). For mining tools a very high manganese steel (Hadfields steel) - this is not a true tool steel. The best place to start is by looking at the ranking of the properties which you want - hardness v toughness v strength - and then use this to put the steels in rank order. Price and availablity then sort the problem out for you (in the real world).
Q:How does a 1911 react to steel casings?
This better placed in the hunting section of sports. That is the area for gun questions. I've never used that Russian stuff in my guns. I would stick with brass or Aluminum Blaser ammo.
Q:Strength of aluminum/steel i-beams?
Structural steel is stronger than structural aluminum. If the structural design is adequate for using an 8 structural aluminum I beam, you can certainly use an 8 structural steel I- beam and if the price is better, you can also use a 10 structural steel light weight channel. If it is on the coast, prime it well and keep it painted. Potential corrosion trouble spots and fasteners can be sprayed with automotive undercoating.
Q:What were some steel advances in industries? 10 points!?
The single most important important advance in steel production was learning to accurately control carbon content. This was done through the Bessemer Process in which air was blown through molten iron to burn out impurities and excess carbon. Low carbon iron (wrought iron) could be easily worked into shapes. Medium carbon iron could be cast into useful and durable shapes. High carbon steel could be used for structural uses (beams and girders). Adding alloys such as nickel and silicon could produce very tough steels and steels resistant to rust. Adding vanadium to steel engine parts allowed Ford to produce finely machined engines in huge numbers with existing machinery.
Q:Where are the coils and the steel plates used? Where did the steel plate come from?
Steel plate is divided into many kinds of PU, low alloy, boiler plate, vessel plate, high strength plate, etc..
Q:when was steel first made?
Even in very early iron, a small amount of steel was produced by carburization, where the iron picks up carbon by laying in hot coals before quenching. This produces a thin layer of steel on the surface of the iron. By about 300 BC Damascus steel was being produced by the crucible method on the Indian subcontinent, and the Romans used steel from Noricum. In the first century BC the Chinese were melting cast iron and wrought iron together to make steel.
Q:Steel question?
Strength of metals is normally measured by the tensile strength as the main measure although this is not the only property as hardness is another big factor. Basically, iron is soft and steel is hard. Plain iron is stretchy and does not corrode quickly, whereas steel is much stiffer and corrodes more quickly. The tensile strength of cold worked iron is about half that of an average steel, likewise the hardness is about half that of steel too. Pure iron, which is rarely used, is even weaker and softer again and a bit more like softer materials like copper and aluminium. Where confusion comes in is that there is another iron - Cast Iron - which is totally different to both iron and steel. Cast iron is very hard and tough but incredibly brittle so its properties are very different.

Q:Sealing stainless steel?
Make a paste from Lemon Juice and salt, scrub gently, and then rinse with water. To clean a stainless steel surface, use mild detergent,or baking soda or vinegar diluted in water. Clean, then dry with a soft cloth. Most stainless steel has a grain; if you are using any kind of an abrasive on a stainless surface, always make sure you clean in the direction of the grain. The don'ts are: Don't use bleach. Don't use steel wool unless it is an absolute last resort. Some of the fine particles can lodge in the surface of the stainless and will eventually rust, giving the appearance that the stainless itself is rusting. Don't let the following food items (ketchup, mustard, mayonnaise, lemon juice, vinegar, salt, salad dressings) remain on your stainless surfaces for any length of time. If they sit on the stainless for more than a few minutes, they may bleach it out. You can actually rub out this white area with a very fine Scotchbrite pad. Make sure you are going along the grain lines and not at right angles to them.
