Roofing Machine Introduction 

Due to its rigid base and strong framing, this roof panel making machine has a production speed of 40 meters/min.

Some non-metal material parts installed in this production line are helpful to prevent scratching damages to the roofing panel surface.

The roller dies material is 45# carbon steel (GB-Chinese Standard, equal to ASTM 1045) and its surface is hard chrome plated, so the roller has a long time service time.

The center shafts are made of 40Cr Steel (GB-Chinese Standard, equal to ASTM 5140). After tempering heat treatment, they have higher hardness.

The shear mold material is D2 (High carbon-chromium tool steel), It can bear over two million times shearing in a normal production situation.

In conclusion, this roll forming machine can produce roofing panels automatically, continuously at a high speed. It is easy to operate, maintain, and has a long service life.
