Production characteristic and use
 
1: This kind of machine can produce C , Z two profiles, through the exchange side of the roller up and down position to achieve C , Z purlin conversion , just need about half an hour to achieve saving time. This machine also can automatically adjust roller horizontal distance to achieve C or Z purlins pf the width with high precision , but also save time to increase production.
2: One machine can produce differenct C/Z Purlins throught simple manual stepless adjustment, when to produce different profiles, no need to change the forming rollers. In the process, machine adopt automactic control model, it can auto pumch, cut, forming based on inputting length of purlin, portrait hole distance, quantity, etc datas.
3: C/Z purlin roll former make up of decoiler, feeding, leveling, 2 sets hy
