BASE MATERIAL:Hot-dip GALVANIZED Steel

In continuous units in cold rolled steel strip, galvanized steel (electro galvanized and hot dip galvanized) as substrate, after surface pretreatment (degreasing and science processing), using the method of roll coating, coated with a layer or multi-layer liquid coating of plate, after baking and cooling income is the coating steel plate. Because the coating can have a variety of colors, on the habits of the coated steel sheet is called color coating steel plate. Because the coating is carried out before the sheet metal forming, in foreign countries which is called pre coating plate.

Color coated steel sheet is an organic coating coating on the steel surface, it has the advantages of beautiful appearance, bright color, high strength, good corrosion resistance, easy processing molding, but also allows the user to reduce costs, reduce pollution.

From the United States in 1935 to establish the first continuously coated steel line to begin, color coated steel plate has been widely applied, the current color coated plate varieties, about more than 600 kinds, the advantages of color coated sheet and organic polymer and steel plate of the two, which has good colorability, organic polymer molding, corrosion resistance and decorative, and steel plate with high strength and easy processing, can easily be punching cutting, bending, deep drawing processing. Made this makes organic coated steel sheet products have excellent practical, decorative, workability, durability.

Q:What's the material of ASTM A653 G30 galvanized sheet?
Galvanized sheet refers to the surface coated with a layer of zinc steel plate. Zinc plating is an economical and effective method of corrosion protection, and about half of the world's zinc production is used in this process.
Q:What do you pay attention to?
1, the plastic bumper with 150-320# sandpaper, if the upwarping phenomenon in the injured, also with a knife will become warped skin scraping.2, in addition to oil, dust, after the proportion of the mixture of good ash fill the depression, to dry solid, first with 320-400# sandpaper polished, and then use 600-800# sandpaper grinding.3. After drying, place a primer newspaper at about 40mm of the ash.4, after removing oil and dust, with diluted primer (primer and quick drying diluent ratio of 1:1), empty spray again, dry and then spray again. In order to reduce the number of spraying and grinding time, it is necessary to ensure the smooth flow of primer, without flashing between each time. Dry the surface of the paint film, until the primer lose brightness, you can continue spraying, and then go round and round until you reach the thickness of the depression.5, in order to shorten the volatilization time, can use high temperature equipment baking, do not have to remove the newspaper, dry solid with 600-800# sandpaper to throw flat, but must not wear primer layer leakage.
Q:The difference between steel edge sealing strip and steel plate putty water stop belt
The steel sealing strip is made of pure steel plate and can be divided into galvanized steel sheet, ordinary steel plate and stainless steel water stop belt.
Q:Is color steel plate the same as color steel tile?
Color steel plate color steel plate refers to color coated steel plate, color coated steel plate is a kind of organic coated steel plate.Color steel plate coating is cold-rolled steel sheet, galvanized steel sheet, after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baked, cured and made of products.
Q:Why can steel HPB300, steel plate without Q300, steel structure manuscript review, but also continued the Q235, why not improve it?
Carbon steel according to the steel yield strength is divided into 5 grades: Q195, Q215, Q235, Q255 and Q275 of each grade because the quality is divided into A, B, C, D grade, with a maximum of four kinds, some only one; this is just plain carbon steel, the price is cheap, generally not heat treatment. Only quality carbon steel has the value of heat treatment.
Q:What is a die steel plate?
Pressure plate template is made of galvanized steel sheet or the antiseptic treatment, the machine rolled into a groove plate with a cross section of the ladder waveform or project template material open box steel shell.
Q:How can the offset film affixed to the cold-rolled steel sheet be removed?
On the hard surface of the self-adhesive mark, we can use non greasy wash water on the surface of the object, and then gently wipe with soft cloth; with industrial alcohol or gasoline can also remove these traces. If these stickers are found on the skin, they can also be removed with lemon juice.
Q:What's the difference between hot-rolled seamless steel tube and cold-rolled seamless steel tube?
Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.
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: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).
