Our Silo Manufacture Unit
We have 20 sets SM30, SM40, SM50 silo profiling unit, part of them are imported from Germany. We will use the different model of silo profilling units according to the different silo diameter and plate thickness. The whole unit is composed by de-coiling machine to send the steel plate to profile machine, profile machine to curve the steel plate for certain diameter, folding machine to bend and seam the 5-layer joint structure, supports structure that rise the silo body by steady wheels.
