The invention relates to a checkered plate as well as a preparation method and application thereof. The checkered plate comprises the following chemical components: 0.03%-0.08% of C, 0.1%-0.2% of Si, 0.5%-1.5% of Mn, less than or equal to 0.03% of P, less than or equal to 0.005% of S, 0.02%-0.06% of Als, 0.06%-0.16% of Ti, 0.1%-0.4% of Cr, 0.003%-0.007% of N and the balance of Fe and inevitable impurities. The checkered plate with excellent mechanical properties is provided by regulating and controlling the chemical components and the content of the checkered plate, the performance and pattern height requirements of a 700MPa high-strength checkered plate can be met, high strength and light weight of the checkered plate are realized, the checkered plate has outstanding production benefits and application values, and production practices prove that the product performance is good, and the production cost is low. And the method is popularized and used.
