The invention discloses 280-MPa-grade strip steel for extra-deep drawing and a production method of the strip steel. The strip steel comprises the following casting blank components in mass content: no more than 0.0030% of C, no more than 0.02% of Si, 0.07-0.15% of Mn, no more than 0.012% of P, no more than 0.012% of S, no more than 0.0005% of B, no more than 0.0045% of N, 0.023-0.050% of Als, 0.030-0.045% of Ti, no more than 0.04% of Cr, and the balance of Fe and inevitable impurities. The production method comprises the following working procedures: steelmaking, continuous casting, heating, hot rolling, cold rolling, continuous zinc coating, and finishing. According to the production method disclosed by the invention, interstitial atoms in extra-low-carbon high-strength steel are removed by adopting a Ti alloying method; through the adjustment of technological parameters for the composition design, steelmaking, continuous casting, hot rolling, cold rolling, continuous zinc coating, and finishing, the strip steel for extra-deep drawing is successfully produced; the tensile strength, the yield strength and the elongation of the strip steel correspondingly reach 280-290 MPa, 140-160 MPa, and 45% or above; and the punch forming performance is good.
