Steel window pressing line structure and mounting method

The invention relates to the field of steel windows, in particular to a steel window pressing line structure and a mounting method.The steel window pressing line structure comprises a pressing line clamping base and an aluminum pressing line, the bottom of the pressing line clamping base is used for being fixed to the end face of a sash material, and a pressing line embedding groove allowing the aluminum pressing line to be embedded is formed in the end face of the pressing line clamping base; the inner wall of the pressing line caulking groove abuts against the outer wall of the aluminum pressing line to form fixation, and a mounting gap allowing the end of the glass to be embedded therein is reserved between the aluminum pressing line and the sash material. According to the steel window, due to the arrangement of the line pressing clamping base and the line pressing caulking groove, a worker can disassemble and replace the glass conveniently, the whole steel window does not need to be disassembled and repla
