The invention discloses a tensile steel wire rope for an automatic garage door. The wire rope solves the problems, including easy aging, easy breaking and a short service life, of the steel wire rope of the garage door in the prior art, increases the tensile stress of the wire rope and prolongs service time. The tensile steel wire rope comprises a wire rope body, a door plate connecting head and a lock head; the connecting head is arranged at one end of the wire rope body and used for being connected with the door plate of the garage door, and the lock head makes the other end of the wire rope fixedly connected with the wire rope body to form a buckle which is used for being connected with the wire rope rolling wheel of the garage door; the middle part of the wire rope body is sleeved with a wear-resistant sleeve; the door plate connecting head is provided with threaded holes for being connected with the door plate through bolts, and the wire rope body comprises a rope core and a plurality of ropes around the rope core. The tensile steel wire rope has the advantages of being simple and reliable in structure, good in yielding degree and large in tensile stress, is suitable for the garage door metalworking industry and has a broad market prospect.
