General Information Of  Prepainted Galvanized Steel

With GI as base metal, 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 steel. Pre-painted galvanized steel is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.

Q:What's the density of the 0.5 color steel plate?
We often see the color steel plate refers to the processing of sheet metal, the thickness of about 50~100mm, it is composed of the middle filler and two sides of color steel plate. Among them, the color plate thickness of 0.4mm, 0.5mm, 0.6mm and other different thickness, the middle layer can be polyurethane, rock wool or foam plastic. Because of the special profiles, the construction of the building with colored steel plate is very fast (such as the Xiaotangshan hospital in SARS), but the strength is low. The substrate of the color coated steel plate is a cold rolled substrate, a hot-dip galvanized substrate and an electro galvanized substrate. The coating types can be divided into polyester, silicon modified polyester, vinylidene fluoride and two plastic sol. The surface state of color coated steel sheet can be divided into coated plate, embossed plate and printed board.
Q:The difference between color steel and stainless steel
The difference is that an ordinary steel plate is painted with antirust paint and one is made of stainless steelThe same is true of steel, steel and steelIt's essentially different
Q:Excuse me, what's the difference between cold rolled steel plate and hot plate in steel plate?
In general, cold rolled steel has better strength, hot rolled steel plate has better ductility. The general thickness of cold rolled is relatively small, can have a larger thickness. Cold rolled steel plate surface quality, appearance and dimensional accuracy than the hot plate, and the thickness of the product right rolling thin to about 0.18mm, so it is popular for. The acceptance of the products, can ask professional personage.
Q:What is muotileaved spring? What is the little leaf spring?
Leaves: by the middle thick and thin steel sheet at both ends of the superposition of equal width. The plate section changes little leaf spring, from the middle to both ends of the cross section is gradually different, therefore the rolling process is more complex, the price is expensive than multi leaf spring. Compared with less leaf spring leaf spring, in the same stiffness (i.e. the same carrying capacity) under the condition of less than the spring leaf light is approximately 50%, reducing fuel consumption, increased ride comfort. And between the little leaf spring monolithic contact, reduces the relative friction and vibration, the ride comfort is increased.
Q:What is reinforced steel plate?
The cold rolling is based on the hot rolling, and then the steel plate is formed by cold rolling after pickling.
Q:What are the functions and classifications of galvanized sheet?
Transportation industry: car, car, car shell ceiling board, tractor, tram, container, highway fence, ship bulkhead etc.Other instruments shell, trash, billboards, watches, photographic equipment, measuring devices and other color coated steel plate with hot galvanized plate, hot galvanized plate, galvanized plate as the substrate, the surface of galvanized plate type pre processing include: hot galvanized plate, galvanized plate, tinplate, galvanized plate pressing and molding, with connecting hooks, without any accessories can be securely firmly connected mesh columns.Galvanized sheet according to its use can be divided into: activated alumina, galvanized plate, desiccant, galvanized plate and catalyst galvanized sheet. The inner cavity of the working room is made of high quality galvanized or stainless steel plate to make it rustproof and clean;
Q:How much is one meter for laser cutting steel plates?
The algorithms on the market price are generally:Cut the price of one meter = the thickness of the material to be cut * 1.5 (excluding the price of material costs)(for example: compare 6 millimeters of low carbon steel plate laser cutting one meter price: 6 (plate thickness) * 1.5=9 yuan / meter10 mm low carbon steel, laser cutting one meter price: 10 (plate thickness) * 1.5=15 yuan / meter12 mm low carbon steel, laser cutting one meter price: 12 (plate thickness) * 1.5=18 yuan / meterAccording to this formula, we can get the price of cutting one meter with different thickness
Q:What's the difference between profiled steel sheet and color steel plate?
A kind of color steel plate is in fact, but now the normal pressure plate to floor plate thickness in 0.7-1.5MM is used in galvanized coil is the main steel structure building, airport, train station, subway station, shopping malls, etc. some of the large span steel structure.
Q:How to introduce carbon steel plate?
According to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free cutting steel structure three, carbon structural steel and steel construction project is divided into two kinds of structural steel and machinery manufacturing; (2) by refining methods can be divided into open hearth steel, steel converter; (3) according to the method of desoxydation can be divided into boiling Teng steel (F), steel (Z) and SEMIKILLED steel (b) and special steel (TZ); (4) according to the carbon content of the steel can be divided into low carbon steel (WC = 0.25%), carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%); (5) according to the the quality of the steel can be divided into ordinary carbon steel (carbon steel with phosphorus, sulfur, high quality carbon steel (P), low sulfur and high quality steel (P), lower sulfur) and super high quality steel.
Q:What type of welding rod is used for steel Q245R and Q235B material?
Q245R is generally used in boiler or pressure vessel, if it is a large diameter cylinder welding body in wall thickness below 8mm recommended the use of arc welding J507 welding rod, double welding, carbon arc gouging back, to obtain qualifiedQuality; when the wall thickness is thicker, submerged arc welding can be used and welding with H08MnA welding wire and HJ431 flux is used;
