Main Feature of Z27 BMP Rolled Steel Coil Construction Roofing Construction

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.
Standard seaworthy export packing: 3 layers of packing, inside is kraft paper, water plastic film is in the middle and outside GI steel sheet to be covered by steel strips with lock, with inner coil sleeve.

Q:What are the common defects in billet? What's the cause?
4. Tungsten inclusion;Six, arc scratch and heat crack and overlap: 1:Two reheat cracks 3 cracks
Q:Continuous casting billet has slag inclusion and air hole
the only way to avoid pinhole of slag situation.1, after foaming, a large amount of gas and residue are produced, which is the main source of porosity and slag inclusion in the cast steel.2, steel casting pouring system or ingate structure is not reasonable, easy to make the gas and residue involved in the liquid metal, the formation of porosity and slag.3, pouring temperature is too low, can not make the cast steel parts of the gas and residue fully excluded, floating up to the top of the casting, but also easy to produce porosity and slag inclusion.4, in some parts of the cast steel parts, when the permeability of the paint is very low, due to the role of gas back pressure, it is easy to make the gasification gas wrapped in the epidermis, forming a package of gas".
Q:What is the difference between steel and billet in the process?
Square is a square steel hollow, with iron produced; but it is a square steel billet is generally solid, forging or casting molding.
Q:Which is good for pure iron billet?
If you would like to consult more detailed information, I suggest you choose Shanghai far west special steel products Co., ltd..
Q:Billet prices skyrocketing weekend, Southern China steel prices rose?
In December 5th, the billet price in Hebei was 2780 yuan per ton, a new high since two years and three months, a rise of more than 85% over the same period of last year.
Q:What is the drop per minute of the billet temperature at 850?
Cold rolling is not considered. The initial rolling temperature (surface) of the billet is generally 1000-1150 degrees. Generally, the temperature decreases gradually during the rolling process (a small section of high speed wire has a temperature rising process), usually above 750 degrees
Q:What about carbon 4 and carbon 5?
This is isomericCarbon four is butane, n-butane and isobutaneCarbon five is pentane pentane. ISO pentane. PentaneThey are intermediates in refining
Q:What does the billet of the steel plant refer to?And steel what is the difference?
The main deformation of reinforced by ribs, binding capacity larger and concrete, so it can better withstand external force. Steel is widely used in all kinds of building structure, especially for large, heavy, light and thin wall structure of high-rise building.
Q:How can carbon and carbon in a fishing rod be distinguished?
Carbon fishing rod is divided into: carbon, pure carbon, high carbon.Carbon packaging, as the name suggests, two layers of material, the outside is a layer of carbon cloth, the inside layer is glass fiber, epoxy cloth. This kind of pole price is lower, this kind of pole does not recommend the brand, because the price is low, does not need to buy the brand. With a few times you can change, for beginners.Pure carbon refers to the overall use of 30T carbon cloth below the production of fishing rod, general 24T, 30T based, carbon content of more than 98%. The price is moderate, the fishing rod is recommended in the field of Koi, Koi a large proportion of domestic brands is unmatched, good quality.High carbon refers to the overall use of 30T carbon cloth above the fishing rod, but not the whole fishing rod is made of a carbon cloth.
Q:What is billet?
Mould blank and continuous casting billet: mould blank and continuous casting billet,
