We provide full-process, deep customization services:
We specialize in the design, fabrication, and installation of large-capacity, highly sealed, and long-lasting prefabricated steel silos, providing efficient and reliable solutions for bulk material storage and handling in the agricultural, industrial, construction, chemical, and logistics sectors. Utilizing advanced spiral seam or bolted connection technology, combined with scientific material flow design and long-term anti-corrosion technology, our steel silos ensure stable quality, minimal loss, and smooth discharge for grains, feed, cement, fly ash, fertilizers, chemical raw materials, and other bulk materials, serving as the core equipment of modern bulk storage systems.
Features & Core Advantages
Superior Sealing & Material Preservation
Continuous spiral seam technology or special sealing profiles and sealants provide far better airtightness than traditional concrete silos. This is critical for grain storage, enabling effective fumigation and blocking moisture/pests to maintain germination rates and minimize loss
Scientific Flow Design & Discharge Guarantee
Flow property analysis based on material characteristics optimizes hopper geometry and outlet size for mass flow or funnel flow. Equipped with vibrators, air cannons, or mechanical dischargers to eliminate arching, ratholing, segregation, ensuring FIFO and complete discharge
Modular Rapid Construction & Minimal Maintenance
Standardized prefabrication of all components allows on-site assembly or spiral winding only, construction is several times faster than concrete silos. The hot-dip galvanizing system eliminates periodic painting, resulting in very low lifecycle maintenance costs, ideal for remote projects
High Degree of Automation & Smart Integration
Seamless integration with inlet weighing, multi-point temperature sensing, level monitoring, automatic aeration, dust control. PLC/SCADA enables remote monitoring and automation for real-time data on temperature, humidity, and inventory, achieving unmanned, intelligent storage management
Strong Environmental Adaptability & Safety Design
Structural design fully considers wind, snow, seismic loads, and material lateral pressure. For combustible/explosive dusts (e.g., grain, coal, aluminum), designs can include explosion vents, anti-static grounding, and spark-proof tool interfaces, complying with NFPA or ATEX standards.

Parameter |
Specification Range / Standards |
Technical Notes & Material-Specific Considerations |
|
Design Capacity |
50 tons - 50,000 tons+ (single silo) |
Capacity based on material bulk density (e.g., grain 0.7-0.75 t/m³, cement 1.2-1.5 t/m³) and process needs. Single or multiple silo configurations available |
|
Structure Type |
Spiral Silo, Bolted (Panel) Silo |
Spiral silos offer excellent airtightness for grains/light powders; Bolted silos allow greater flexibility in diameter/height for large, heavy materials |
|
Silo Dimensions |
Diameter: 3.6m - 50m; Height: 10m - 60m |
Diameter-to-height ratio optimized for mass flow or funnel flow to prevent arching and segregation
|
|
Bottom Type |
Hopper Bottom (Steel/Concrete), Flat Bottom (with Sweeper) |
Hopper angle (typically ≥45°) designed per material angle of repose for gravity discharge; Flat bottom with sweepers for cohesive materials |
|
Main Material |
Q235B, Q345B Hot-Rolled Steel Plate; Galvanized Sheet (Zinc ≥275g/m²) |
Standard high-strength galvanized steel provides superior corrosion protection. Special materials (e.g., urea, chemicals) may use stainless-clad or special coatings
|
|
Design Codes |
GB 50322 (Grain Silos), GB 50009 (Loads), GB 50017 (Steel), API 650, EN 1991-4 |
Analysis covers static pressure, dynamic pressure (discharge impact), wind, snow, seismic loads, with special attention to eccentric loads from asymmetric discharge |
|
Corrosion Protection |
Hot-Dip Galvanizing (HDG, mainstream), Epoxy Zinc-rich Primer + PU Topcoat, Special Lining |
HDG provides cathodic protection, the most cost-effective long-term solution for grain and general industrial storage, with a design life of over 30 years |
|
Auxiliary Systems |
Inlet, Outlet (Gate, Conveyor), Aeration, Temperature Monitoring, Level Indicator, Dust Removal, Cleaning System |
Customized per material properties (size, moisture, explosibility) for safe, efficient, automated operation. Grain silos require aeration and temperature monitoring to prevent spoilage |
|
Sealing & Airtightness |
Airtightness meets GB/T 17428 standard |
Special sealants and techniques ensure high airtightness for fumigation or protecting oxidizable materials |
