Introduction

Flat Bottom Steel Silo

The Flat Bottom Silo from Manxing Machinery is specially engineered for long-term bulk grain storage applications.

Built with 275g/m² hot-dip galvanized steel sheets, our silos deliver exceptional corrosion resistance and a service life exceeding 30 years.

The flat bottom structure allows for large storage capacity, ranging from 500 to 10,000 tons, and is compatible with aeration, temperature control, and automatic unloading systems to maintain grain quality.

Each silo is equipped with:

Strong corrugated steel walls for durability and wind resistance
Advanced sealing design to prevent moisture and pests
Optional ventilation and temperature monitoring systems
Customized unloading systems for easy grain discharge
