Product Description

Product Description

Product Description
We offer Galvanized Steel Grain Storage Silos with capacities ranging from 50 tons to 10,000 tons, ideal for large-scale storage of maize, wheat, soybeans, rice, and other grains. Available in flat bottom, cone bottom, fluidized discharge, and multi-outlet discharging types, our silos meet a wide range of operational needs.
As a full-solution provider, we also undertake turnkey silo projects, including:

• Process and civil engineering design

• Complete automated control systems

• Equipment for grain lifting, cleaning, magnetic separation, metering, drying, and fumigation

• Systems for cold storage, ventilation, dust collection, and temperature/moisture monitoring

• On-site installation, commissioning, and operator training

With high durability, corrosion resistance, and flexible configurations, our grain silos ensure safe, long-term storage with minimal maintenance.
Product Structure Highlights
Our galvanized steel grain silos are designed for durability, safety, and efficient storage:

1. Roof System: Each silo roof is equipped with natural ventilation windows, manholes, roof ladders, and safety guardrails, ensuring safe maintenance access and proper airflow.

2. Wall Panels: The silo body is built from high-quality hot-dip galvanized steel plates, shaped into a corrugated (wavy) profile using precision equipment. Pre-punched connection holes allow for quick and secure assembly with high-strength bolts.

3. Steel Cone Bottom: The bottom structure includes columns, ring beams, conical plates, and tension bars. All columns are made from standardized L-beams, providing strong structural support for stable and long-term grain storage.
