The invention discloses a spraying type steel barrier, which comprises columns, upper cross bars, lower cross bars and vertical bars. The main bodies of the columns, the upper cross bars, the lower cross bars and the vertical bars are all integrated style steel works. The columns are made from the galvanized steel strip, made into steel pipe of a certain shape and sprayed with plastic or paint; the upper cross bars, the lower cross bars and the vertical bars are integrated parts which the upper cross bars, the lower cross bars and the vertical bars are respectively made from the galvanized steel strip, steel pipes of a certain shape are made through extrusion forming of the steel pipe stock mould, seam welding of the high frequency induction welder and extrusion forming of the steel pipe shaping mould and the integrated parts are formed by placing the vertical bars between the upper cross bars and the lower cross bars, welding and fixing, and at last spraying plastic or paint on the exterior surface of the integrated parts. The spraying type steel barrier has the advantages of high structural strength, deformation resistance, beautiful and clean barrier surface, rustiness resistance, easy cleaning, greatly reduced maintenance cost, both the beautiful appearance of the PVC plastic steel barrier and the high strength of the assembly type barrier.
