Rx4.0m/m SM-40 Spiral Steel Silo Forming Machine is the forming machine of our circular steel plate storehouse (a metallic container) that we released in the market in 2005. It is a new SM-40 Spiral Steel Silo Forming Machine designed on the basis of the LIPP-SM40 machine from Germany. It has all the functions that the SM40 machine has.

This roll forming machine is particularly designed for manufacturing large diameter corrugated metal culvert pipes which are commonly found beneath roadways or under railroad tracks to allow water to flow from one side to the other.
