高强钢是彩涂产品的发展趋势之一，目前国外使用比较多的是屈服强度为350等级的彩涂钢板。生产这类强度的钢板通常有两种工艺，一是采用碳锰钢，在炼钢时采用C、Mn等强化元素，并利用强大的热轧、冷轧轧制力来生产相对较薄的高强彩涂钢板，像马钢等国内外全流程钢厂（矿石到成品）都采用这样的生产工艺。另一种方法就是通过降低热镀锌机组的退火温度，使材料没有完全退火，还部分保留轧硬态来提高强度，目前国内多数镀锌及彩涂厂是采用这个工艺，因为他们没有炼钢工序，在市场上购买轧硬卷或热轧板也没有相应的高强钢种。
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.
高强度PCM彩涂钢板基材为高强度钢板，高强度钢板正面设有钝化层，钝化层上涂有底漆层，底漆层上涂有水性辊涂面漆层。采用高强度钢板生产PCM彩涂钢板，钢板的屈服强度YP≥400Mpa，抗拉强度TS≥450Mpa。如使用普通钢板生产，需要0.5mm以上厚度才能满足使用要求，而使用高强度钢板生产，0.4mm以下厚度就可达到同样的性能要求,从而可以降低冰箱的生产成本，具有强度高、不易变形等特点。钢板的表面上使用水性辊涂漆可以使生产过程环保化、表面硬度高，丰满度好。
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.
一般工业建筑的设计使用年限为15-20年，马钢彩涂钢板在设计年限内是不需要更换的。马钢普通（PE）彩涂板的建筑，使用时间已经10年，到目前为止颜色、涂层等性能变化并不大，彩涂板完好无损。但如果采用一般的彩涂钢板，使用寿命通常为3-5年，甚至更短，在设计期内至少需要更换2次。
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.
由于马钢彩涂板良好的实物质量，在市场上马钢彩涂板的价格比一般低价彩涂板贵几百元一吨，但是如果按一般彩涂板在设计使用年限内更换一次测算的话，使用马钢彩涂板的成本只是一般彩涂板的60％左右。由此推算马钢彩涂板的售价可以比一般彩涂板售价贵50%左右，这还不考虑其它影响，如对企业形象影响，更换维护时对生产影响等。
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.
