Silo Features1. The silo constructed with the steel silo making machine has optimal overall performance and long lifespan. The seaming thickness is 5 times the thickness of the base material. Apart from the strengthened load carrying capacity, the silo has the advantage of good stability and long lifespan over other product.
2. Optimal sealing performance and wide applications. Our cold roll forming line provides seaming with good airtightness. It helps prevent the granular and powdery grain stored being influenced by the humidity outside the silo. In addition, the silo constructed can satisfy the technological requirement for disinsection or fumigation. Application for storing liquid is also available.
3. Short construction period and low construction cost. It only takes about 5 days to construct the 1000 ton silo with our cold roll forming line. The silo weight is just one-sixth that of the cement silo. Therefore, the silo construction cost is reduced, accordingly.
4. Small land occupation, good adaptability and easy maintenance. The height and diameter of the spiral steel silo is selectable within a large range. The space between the silos can be less than 50m.
