Storage Grain Silo Introduction

A Storage Grain Silo warehouse is a facility specifically designed for storing various grains (such as rice, wheat, maize, etc.), aiming to provide safe, dry, pest-resistant, and moisture-proof storage conditions to ensure the quality and shelf life of the grains. These warehouses typically feature specialized designs and structures, including well-sealed walls and roofs, ventilation systems, temperature and humidity control equipment, etc., to meet the storage requirements of different types of grains. The construction and management of Storage Grain Silo warehouses are crucial links in the grain industry chain, playing an important role in ensuring food supply, reducing grain losses, and safeguarding food security.

The structure of Storage Grain Silo


The column structure used by Coban has significant advantages in terms of mechanical performance, with stiffness approximately twice that of domestic manufacturers. The larger moment of inertia of the columns results in stronger resistance to deformation and greater load-bearing capacity. Columns with larger moment of inertia provide more stability and reliability for the same cross-sectional area.

Wall Panels

While ensuring the strength of the silo, Coban has adopted a more reasonable corrugation spacing for the wall panels to reduce the chance of material accumulation on the walls. The wall panels are made of high-strength galvanized steel with a zinc coating ranging from 275g to 600g, sourced from state-owned steel mills like Handan Steel and directly imported high-zinc-layer plates from POSCO in South Korea. Quality sealing strips are used at the joints of the wall panels for waterproof sealing.

Roof Panels

The design of the roof panels and framework takes into account the roof load and wind resistance requirements to ensure safety and reliability. Fully galvanized, the roof panels can be coated with magnesium-aluminum-zinc plates and sealed with a bite edge structure for better corrosion resistance and sealing performance. Equipped with roof manholes, natural ventilation holes, axial flow fan holes, roof guardrails, and ladders, the roof openings are flanged and covered with plates for rainproof sealing.

Ventilation Floor Panels

The ventilation floor panels feature bridge-style holes to effectively prevent grain and impurities from getting stuck, ensuring long-term ventilation effectiveness. Special supports below the ventilation panels can withstand grain pressure and facilitate the operation of sweepers.

Connection to the Foundation

Coban Storage Grain Silo can be connected to the foundation using internationally common bolt connections, making construction simpler, stronger, and more convenient for relocation. Gaps between the wall and the foundation are filled with weather-resistant sealing strips and waterproof coatings.

Advantages of Storage Grain Silo

High strength and durability

Storage Grain Silo are constructed with high-quality materials and robust structural design, providing excellent resistance to wind, seismic activity, and compression, ensuring long-term stability for storing large quantities of grain.

Excellent sealing performance

The structural design of grain storage silos emphasizes sealing, effectively preventing the ingress of moisture, pests, and other contaminants, ensuring the quality and safety of the stored grain.

Ventilation system

Storage Grain Silo are equipped with efficient ventilation systems to ensure proper air circulation within the storage environment, preventing grain from molding and rotting and maintaining its freshness and quality.

Intelligent management

Some modern Storage Grain Silo are equipped with intelligent management systems that monitor and adjust parameters such as temperature and humidity in real-time, improving management efficiency and accuracy.

Flexibility and customization

The design of grain storage silos offers flexibility, allowing for customization according to customer requirements for different sizes and capacities, meeting various usage needs.


Storage Grain Silo are equipped with comprehensive safety features such as fire suppression systems and monitoring systems to ensure safe operation and reduce the occurrence of fires and other accidents.

Environmental friendliness

Storage Grain Silo are designed and operated with environmental protection in mind, employing energy-saving and emission-reducing technologies and measures to minimize environmental impact.

Storage Grain Silo technical parameters

Scientifically speaking, the Silo capacity should be measured with volume (m3). Even in the same grain Silo, the storage tons will be different for different grains with different densities. The following table is calculated based on a  Silo density of 0.75kg/m3, and surely HKB customizes  Silo systems unique for you.
