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: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
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:How can steel plates with a thickness of 1MM be welded?
The seam is also called the wheel welding equipment for the production, mainly uses fuel exhaust pipe seal. The principle is similar to that of spot welding. The difference is that the output current is uninterrupted.
Q:What is muotileaved spring? What is the little leaf spring?
Leaf: ranging from multiple pieces of the same length, width of sheet steel by adding together. Multi leaf spring of each leaf into superposition inverted triangle shape, the top plate is the longest, the bottom plate is the shortest, piece number and supporting the weight of the bus plate, plate more thick more shorter, more rigid spring. However, when the leaf springs are used for a long time, they slide and rub each other. The relative friction between the steel plates also causes spring deformation, resulting in uneven running.
Q:What is the function of an automobile leaf spring?
Spring: the multi length and unequal curvature of the folded plate. After installation ends naturally curved upward. When the impact force of the wheel face came when the steel plate deformation, play a buffer, damping effect
Q:What's the difference between a spray plate and a colored steel plate?
Plastic sheet, first can choose the thickness and material on the plate, and then spray processing, and then processing the plastic powder color and quality can choose according to your requirements, general plastic plate from high-end to low-end can meet your requirements, if you need to own production will be cumbersome!
Q:The method of making spring steel for automobile?
The south is the car plate making machetes bow. Hardness enough. It is important to quench the heat. A big jump makes a big mouth. Soft edge. Special blacksmith needs to be quenched
Q:Should the carbon fiber reinforce the steel bar on the side of the beam?
Not necessarily, mainly depends on how the design is calculated, usually put 100~200mm carbon fiber layering
Q:What's the difference between the three kinds of pickling plate, cold rolled plate and hot rolled plate?
In fact, the pickling steel plate is a product between the hot rolled plate and the cold rolled plate. The process before the cold rolling plate is also the pickling substrate, and then cold rolling
Q:How is the normalized steel plate produced?
Normalizing, also known as normalizing, is to heat the workpiece between 727 and 912 degrees Celsius. 40~60min, after a period of heat preservation, is removed from the furnace and cooled by air or by spray, spray, or blow cooling. Its purpose is to make grain refinement and carbide distribution homogenization, to remove the internal stress of materials.
