High strength steel is one of the development trends of color coating products. At present, the yield strength of 350 grade is more commonly used abroad. There are usually two processes for the production of such strength steel plate, one is to use carbon manganese steel, C, Mn and other strengthening elements, and the strong hot and cold rolling force to produce relatively thin high strength color coated steel plate, such as Maanshan Steel and other domestic and foreign steel mills (ore to finished products) are using such production process. Another method is to reduce the annealing temperature of hot galvanizing unit, make the material is not completely annealing, also part of the rolling state to improve the strength, at present most domestic galvanizing and color coating factory is using this process, because they have no steelmaking process, in the market to buy rolling roll or hot rolled plate has no corresponding high strength steel.
The substrate of high strength PCM color coated steel plate is high strength steel plate. The front of the high strength steel plate is equipped with passivation layer, and the passivation layer is coated with water-based roller coating layer. High strength plates were used to produce PCM color-coated plates, with yield strength YP 400 Mpa and tensile strength TS 450 Mpa. If the use of ordinary steel plate production, need more than 0.5mm thickness to meet the requirements of use, and the use of high strength steel plate production, 0.4mm below the thickness can achieve the same performance requirements, so as to reduce the production cost of refrigerators, with the characteristics of high strength, not easy to deformation and so on. The use of water roller paint on the surface of steel plate can make the production process environmentally friendly, high surface hardness and good fullness.
The design service life of general industrial buildings is 15-20 years, and the Masteel color-coated steel plate does not need to be replaced within the design life. Masteel ordinary (PE) color coating plate building, the use of time has been 10 years, so far the color, coating and other performance changes are not much, the color coating plate is intact. However, if the general color-coated steel plate is used, the service life is usually 3-5 years, or even shorter, and it needs to be replaced at least two times during the design period.
Due to the good physical quality of Masteel color coating plate, the price of Shangma steel color coating plate is several hundred yuan a ton more expensive than the general low price color coating plate, but if the general color coating plate is replaced within the design service life, the cost of using Masteel color coating plate is only about 60% of the general color coating board. From this calculation, the price of Masteel color coating plate can be about 50% more expensive than the general color coating plate price, which does not consider other effects, such as the impact on the corporate image, the replacement and maintenance of the production impact.
