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 is the thickness of the water resisting steel plate of the electrical outlet?
The water resisting steel plate of the electric door mainly meets the need of welding between the sleeve and the setting of the water stopping line.
Q:Is galvanized steel plate fire-resistant?
Should be refractory, but the melting point of zinc relative to steel is relatively low, 420 degrees or so, if higher than this temperature, galvanized layer will be destroyed, the bottom plate is no problem.
Q:Can 16Mn steel plate be used instead of Q345D steel plate?
16Mn steel plate is the old brand, the latest brand is Q345, but Q345D has a special requirement than 16Mn, that is, 20 degrees lower temperature test
Q:What is Larson steel sheet pile?"
As a kind of new building materials in the Larson steel sheet pile cofferdam, bridge construction, large pipeline, temporary ditch excavation for retaining, retaining water and sand retaining wall; in the wharf, unloading field wall, retaining wall, Levee Revetment, play an important role in engineering. As a cofferdam, Larson steel sheet pile is not only green and environmental friendly, but also has fast construction speed, low construction cost and good waterproof function.
Q:1.5mm galvanized steel prices?
1.5mm galvanized steel plate price between 4500-6000 yuan.
Q:What is called steel plate sanding process?
Sand blasting can remove the oxide surface and floating rust on the surface of steel plate. It is a good process before anticorrosion painting. Sandblasting of other components may be more useful for pre coating treatment.
Q:What does "rolled steel" mean?.
Generally refers to the thickness below 3, some enterprises have used rolling process, for example, 1.97 of the stainless steel materials market is difficult to buy, the enterprise will use 2 or 2.5 of the material rolling process processing, production of 1.97 thickness.
Q:What welding rod should be used for welding of cast iron and Q235B steel plate?
Q235B is a kind of low carbon steel commonly used in China, good welding performance, applicable to a variety of welding engineering used J422 (new brand E4303) in order to improve the efficiency of welding, and can also be used CO2 welding, welding wire can be used H08.
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:What is the difference between cold rolling and hot rolling?
Hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the hard roll strength and hardness of the rise and decline of toughness index, stamping performance deterioration, only for a simple deformation of parts. Rolled hard rolls can be used as raw material for hot galvanizing plants, because the hot galvanizing units are equipped with annealing lines. The roll weight is usually 6~13.5 tons, and the inside diameter of the steel coil is 610mm. Generally, cold continuous rolling plate and roll should be annealed by continuous annealing (CAPL unit) or bell type furnace to eliminate cold work hardening and rolling stress, and meet the standard mechanical performance indexes. The surface quality, appearance and size accuracy of cold rolled steel plate are superior to those of hot rolled plate.
