K span roll forming machine 610 type
No Girder Super Span Roll Forming Machine

Features of our no girder k span roll forming machine:

1. All the rollers for the no-girder k span roll forming machines are forged from the high quality structural steel and are processed intensely. The surfaces of the rollers are plated with hard chromium. The rollers have a high hardness and long operating life.
2. The power set to automatically transport the colored steel sheet is equipped in the forming press section, which can press the colored steel sheet with the thickness of 0.5~1.5mm. It is not needed to frequently adjust the clearance between the pressing rolls when pressing the sheet with different thickness, which can make the sheet come out from machine normally without scuffing of the coating film of the sheet. Being just like a "foolproof camera", the operation of the no-girder k span roll forming machine is very simple. But the quality of the finished product can be guaranteed.
3. The length of the finished sheet is measured by the electronic measurement instrument or mechanical measurement instrument. The helping hand wheel and the counter are used in the adjustment of the bending of arch sheet, which makes the operation simple and guarantees the quality and the dimensional precision.
4. The hoisting tool is light and handy (The weight of hoisting tool of the United States is 30KG. And the weight of hoisting tool of our company is 2KG). It is convenient to install and uninstall the hoisting tool. Its hoisting speed is quick.
