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 of the width with high precision, but also save time to increase production.
