The steel silo structure usually includes four parts:

  • Roof/Top
  • Body/Cylinder
  • Bottom
  • Control System

Let’s introduce the basic steel silo structure from top to bottom.


  • Support Cone

This cone serves to support the roof sheet, and it is the material entry channel at the same time.


Material level sensors & temperature measurement cable outlet elbows are installed on it (the temperature measurement cable enters the silo from here).

  • Roof Vent

The roof vent consists of a cap, a duct & a flange.


M10*25 bolts connect the cap & the connecting module on the air duct, thus forming a whole vent.

  • Corrugated Sheet

As the main component of the steel silo, the corrugated plate comes out from a CNC production line, not only its appearance is beautiful, its precision & compatibility is high, and it is easy to assemble.


After assembly, the fit is good, the tightness is strong, and the roundness of the silo is great.

  • Stiffener

As an important part of the silo body, it determines the overall stability of the silo.

The stiffener adopts a deep trapezoidal cross-section with wings, which is well-proportioned.


It is formed on a large hydroforming press at one time, and its bearing capacity increases by 10% compared with conventional production.

  • Sealing Fastener (Bolts & Screws)

The sealing fastener connects the steel silo & the stiffener.


It consists of bolts, nuts & rubber pads.

  • Wind Ring

The wind ring is made of high-strength hot-dip galvanized steel pipe, which makes the silo roof as a whole & plays an important role in resisting external wind.


  • Roof Sheet

The roof sheet is made of hot-dip galvanized sheet by forming & punching through a CNC production line.


Its unique double-bending ribs make the silo roof connection tight, firm & non-deformable, stronger load-bearing capacity.

  • Grain Condition Monitor & Control System

With temperature measuring cables, material level & temperature sensors, real-time monitoring of the temperature & humidity of the grain is achievable.


  • Aeration System

When the monitor & control system detects that the grain temperature exceeds the standard, it will automatically start the ventilation fan.


Thus, the heat exchange between the cold air & the material occurs, and finally achieve the cooling & dehumidifying of the grain.

  • Grain Cooling System

Through the grain cooler, the grain temperature in the silo drops, low-temperature refrigeration come to reality.


The grain “breathing” slows, the reproduction of grain insects pauses, the cost of pest control reduces, the quality of stored grain improves, the storage time extends, thus realizing the grain storage safety.

  • Fumigation System

This system is useful for controlling pest damage in grains & reducing waste.


  • Sweep Auger

The sweep auger usually matches the silo diameter, its function is to remove the residual grain at the bottom.
