CZ Purlin Steel Cold Roll Forming Machine Fully Automatic CZ Making
Machine
CZ interchangeable machines can produce C and Z rafters. It can
realize the conversion of C and Z rafters by changing the upper and
lower positions of one roller. It takes half an hour to save time.
It can also adjust the lateral distance of the roller to adjust the
width of C or Z rafter. High precision and time saving to increase
production.
