Q:What are the functions and classifications of galvanized sheet?
Galvanized sheet mainly used in industry: a large number of galvanized sheet, used in automobile manufacturing, refrigeration, construction, ventilation and heating facilities and furniture manufacturing and other fields. Galvanized steel anticorrosion method becomes important, not only because the zinc can form a protective layer on the surface of iron and steel, but also because zinc has the effect of cathodic protection, when the breakage of zinc coating, it can still prevent iron base metal corrosion by cathodic protection.
Q:What kind of steel plate is HIC?
Is suitable for use in acidic environment, hydrogen sulfide corrosion resistance of the steel plate. Also known as hydrogen or hydrogen resistant steel, generally pressure vessel or pipe steel.
Q:Is 5mm thick steel plate tapping M8 thread reliable?
The pitch of the M8 is 1.25, it can attack 4 teeth. The force of the thread is 4-5 teeth. The bottom is not greater than 6.7mm, 8.8 plus elastic pad bolt.
Q:What are hot and cold plates?
Cold rolled coil is made of hot rolled coil as raw material and rolled under the recrystallization temperature at room temperature, including plate and coil. Many steel mills in China, such as Baosteel, WISCO, Anshan Iron and steel company, can be produced. Among them, the delivery is called steel plate, also known as "box plate" or "flat"; the length is very long, the volume of delivery, known as "steel band", also known as "coil.".
Q:Is galvanized iron sheet the same as galvanized steel sheet? solve
The same thing is done to slow down the rate of oxidation. Because the zinc is more active than the iron, the zinc first responds, the zinc reaction is finished, iron should. Thereby slowing down its oxidation.
Q:What is the difference between an open plate and an original plate?
Open and flat from the original flat surface color to distinguish. Because the Kaiping plate originally is rolled strip, the oxide is less, the same time the Kaiping plate and the original flat for a period of time after the original flat in different colors, red, and blue plates.
Q:What's the difference between a spray plate and a colored steel plate?
Then the color, not the quality of the domestic coatings products, fully meet the demand, the high price of imported coating reduces the competitiveness of skin colour in the plastic film is still dependent on imports, lack of high-grade color coating thickness, functional, high strength, rich color coated plate. Therefore, the choice of color steel plate is relatively narrow, and basically are low-end products, but more convenient, you can buy directly!
Q:What welding rod should be used for welding of cast iron and Q235B steel plate?
SUS304 is 18/8 stainless steel. GB brand 0Cr18Ni9, this is an austenitic stainless steel, austenitic welding electrode, such as A102 or A302 welding.
Q:How to choose welding method for welding different plate and thick steel plate?
For welding efficiency:General welding or argon arc welding of thin plate, medium plate with gas shielded welding (such as two welding), thick plate with submerged arc welding (usually not groove, single-sided, once the penetration of up to 20mm).
Q:The difference and usage of color steel sandwich panel and color profiled steel sheet
The wall of the project is made of type 950 rock wool wall sandwich board, and the roof is made of type 960 rock wool roof sandwich board
