As of now, steel silos can be broadly categorized into helical steel silos, assembled steel silos, and welded steel silos, among others. They can also be divided by their applications, such as grain steel silos and building materials steel silos.

Spiral steel plate silos, specifically, they are steel plate silos constructed by mechanical stamping steel plates and assembled with high-tensile bolts. Their structure dictates certain limitations, making them suitable only for small storage facilities with capacities under 2,000 to 3,000 tons. Spiral steel plate silos are not suitable for storing perishable powdery substances like cement or fly ash, as their eye connections result in poor ventilation and sealing properties. However, they do have their advantages. With good ventilation, simple structure, short construction periods, and affordability, they are a suitable choice for grain storage.

The assembled steel plate silo, constructed from folded steel plates and interconnected layer by layer, is designed with a structure that necessitates thin steel plates, making it suitable only for small storage facilities under 5,000 tons. It boasts excellent sealing performance and is capable of storing various powdered materials such as cement, fly ash, and grain. Its thin walls contribute to a shorter lifespan.

Welded steel plate silos, constructed from steel plates joined together, offer excellent airtightness, long service life, and large storage capacity. Compared to the aforementioned types, a single silo can store between 5,000 to 100,000 tons. They are the conventional choice for storing large quantities of materials like cement and fly ash in steel plate silos.
