The invention discloses a production method of a binding strap with tensile strength more than or equal to 1000MPa. The method comprises the following steps: cold-rolling a pickled 30Mn2 hot-rolled coil; uncoiling, stripping and removing burrs, and then carrying out high temperature austenitizing; quenching the coil in a mixed solution consisting of triton X-100, Tween 20 and water; washing with water as conventional means and tempering the coil; naturally air-cooling to room temperature; and coiling. A finished product of the invention is 0.8-1.0mm thick, 1030-1070MPa in tensile strength, 10-12% in elongation rate and no less than 4 times in repeated bending time, and a blue layer which is uniform and dense, strong in adhesive force and 4-6microns thick is generated on the surface. The performances of the finished product completely meet the demands of binding and packaging heavy-coil hot-rolled steel coils.
