步步紧是一种新型建筑用具，使用方法快捷，不仅能节省工作时间，提高工作效率，更能节约大量木材，取代了传统的铁丝捆绑法，罗杆丝杠法，固圈加塞法。

       步步紧连轧机采用国内新技术，是步步紧生产工艺简单化、加工成本降低。该步步紧轧机由电动机、减速机、齿轮分配箱、连轴传动、槽钢机架、铸钢牌坊、特种辊系、耐磨导位、调直剪切或收线部分、数控操作部分等组成。

       Step by step is a new construction equipment, the use of fast, not only can save time, improve work efficiency, more can save a lot of wood, instead of the traditional wire binding method, rod screw method, fixed ring plug method.

       Step by step rolling mill adopts domestic new technology to simplify production process and reduce processing cost. The stepping mill is composed of motor, reducer, gear distribution box, connecting shaft drive, channel steel frame, cast steel arch, special roll system, wear guide, straightening shear or winding part, CNC operation part, etc.
