The spiral folded silo technology originated from Germany, and now SRON has improved its technology during our year's project experience with 6 utility patents and 2 scientific and technological achievements. If not for the limit for diameter and height, spiral folded silo would be the most popular and economical silo solution.



History of spiral silos in China and at SRON

In the 1980s, the Chinese government imported the first 4 sets of spiral folded silo manufacturing machines from Germany. Chinese engineers start to research and decode the technology, and the founder of SRON company has been one of the engineers who participated in the research work. And now we have 28 sets of silo manufacture machines SM30, SM40, SM50.


Rocketing development of spiral silos for the storage of cement and fly ash in China

From the 1990s, China starts fast development and civil construction, spiral silos start rocketing development and application in the storage of cement, fly ash, lime, and mineral powders. For its unique advantages of low investment, fast construction time, easy construction no usage of truck crane, max sealing like a welded silo, no painting, and no maintenance needed.

Our Silo Manufacture Unit

We have 20 sets of SM30, SM40, SM50 silo profiling units, part of them are imported from Germany. We will use the different models of silo profiling units according to the different silo diameters and plate thicknesses.

The whole unit is composed of the de-coiling machine to send the steel plate to the profile machine, a profile machine to curve the steel plate for a certain diameter, a folding machine to bend and seam the 5-layer joint structure, supports structure that rises the silo body by steady wheels.
