A 60-steel hot rolling coil rod with high strength and high plasticity and production method thereof belong to the hot rolling coil rod and production method thereof. The coil rod consists of the following chemical substances by weight percentage (%): 0.57-0.65 % of C, 0.17-0.37 % of Si, 0.50-0.80 % of Mn, 0.16-0.25 % of Cr, <= 0.35 % of P, <= 0.035 % of S, <= 0.30 % of Ni, <= 0.25 % of Cu, and the balance of Fe. The hot rolling coil rod with Phi 6.5 mm has a tensile strength of 990-1060 Mpa, a reduction of area of 50-60 % and a Sorbit rate of 85-90 %. The coil rod and the production method thereof have advantages that the process equipment and parameter setting are reasonable, the long-standing problem is solved, the product quality is improved, the deep processing of the coil rod is easy, a thinner steel wire product is easily drawn, the load that the steel strand processed with the steel wire can bear is substantially increased, the reduction of area of the steel wire is improved, the intermediate thermal treatment process is omitted and the energy is saved.
