Corrugated steel hopper bottom silo is an advanced grain storage equipment, it is useful for storing various grains, seeds, including:
- Sunflower seeds
The hopper bottom’s inclination angle is between 35 to 60 degrees, the grain can flow out of the conical silo on its own under gravity, without residue.
The 60-degree cone bottom grain bin is suitable for storing larger viscosity particles & powdery materials.
As the hopper bottom grain bin doesn’t need a sweep auger for material unloading, which not only simplifies the assembly work but also reduces the total cost.
In addition, the hopper silo’s following features are also attractive:
- Short construction period;
- Optional temperature measurement, ventilation system;
- Mechanization & modernization management;
- Simple disassembly, convenient maintenance, realiable quality;
- Long service life, up to about 30 years.
Generally speaking, hopper bottom silos are mainly used for temporary storage, because they have a smaller capacity than flat bottom silos, with structural steel supports, it is convenient for unloading the stored materials.
Similar to the flat bottom silos, the hopper bottom bins are assembled by the corrugated plates, by fixing these plates to the structural steel frame with bolts & nuts.
Some grain hopper bins are welded structures, such bins have a longer service life, its structure is unlikely to interfere with the material flow.
If you store the grain in the hopper bottom bins according to the design, you can enjoy simple metering & unloading through the cone bottom.
In order to control the flow rate correctly, we SiroSilo design the metal silos with a cone bottom according to stored materials, so as to measure their storage capacity.
To prevent the hopper bottom metal grain silo’s corrosion, we can galvanize or paint it.
Based on the silo capacity, the hopper steel grain silo has 3 types:
- Small (5-20 tons)
Mainly used for the ingredient, feed storage, etc.
- Medium (20-500 tons)
Mainly used in processing plants for transit.
- Large (500-1500 tons)
According to actual needs, it is used to store seeds.
The hopper silo structure is generally the same, its main components are:
- Compression Ring
- Structural Support
- Wind Rings
- Roof Stairs
- Roof Inspection Hole
- Entrance Door
- Bolts & Nuts
- Joints Seal

Hopper Silo Ultimate FAQ Guide
Galvanized silo is actually a steel grain silo, it is assembled by hot-dip galvanized stainless steel sheets.
Hot-dip galvanized steel sheet has ideal corrosion resistance, it is easy for forming & coating, its cost is low, appearance is attractive, it is an ideal material for assembling steel grain silos.
The hot-dip galvanized layer’s electrochemical potential is more negative, and it has excellent electrochemical protection.
As the coating is thick & dense, the coating & steel substrate have a strong bonding force, its durability is good.
The service life of the 600g/m2 hot-dip galvanized steel can reach more than 30 years.
The hot-dip galvanized steel layer does not require maintenance during use, the hot-dip galvanizing process is simple, such process has strong adaptability to the steel shape & size.
In addition to the steel strips, the hot-dip galvanizing process is also widely used for steel pipes, steel wires, and structural parts, its productivity is high.
Compared with other protective coatings economically, the galvanized layer has strong competitiveness, especially for long-term parts, the hot-dip galvanized layer’s cost is much lower compared to paint coating.
What is Hopper in Silo?
According to the bottom shape, the metal grain silo can be divided into flat bottom silo & hopper bottom silo.
The hopper in silo is actually the cone at the grain hopper bins’ bottom.
Because of their inclination, these grain hopper bins can discharge the stored grains without clearing equipment.
The following picture shows the hopper:

Hopper Bottom Feed Bins
Because the farms use fodder to feed poultry & livestock every day, hopper bottom feed bins are more popular among farmers.
The hopper bottom feed bins are particularly convenient for unloading, it does not require unloading equipment.
It is economical.
Hopper Bottom Grain Bins
Generally speaking, farmers or small grain processing plants purchase hopper bottom grain bins.
They can use the hopper bottom grain bins as a transit warehouse, storing grain & seeds for a short period of time.
When the storage period is up, the unloading is also very convenient.
Because the silo bottom is cone-shaped, the bottom has a certain height above the ground, the grain & seeds in the silo can flow out under gravity.
Hopper Bottom Grain Bins Prices
In the Chinese market, 3-30 tons hopper bottom grain bin’s price is RMB3,809.52 to RMB7,936.50/set, which is equal to USD$605.00-USD$1,260.00/set.
How to Build a Hopper Bottom Grain Bin
To build a hopper bottom grain bin, it usually include the following basic steps:
- At the center of the silo foundation, erect a suitable scaffold support, hoist the top roof frame to the scaffold support;
- Install the side cylindrical body sheets, top reinforced stiffeners of the 1st & 2nd rings;
- Install silo roof components;
- Install the side cylindrical body sheets & stiffeners of the remaining rings;
- Lift the hopper silo’s cylindrical body to the foundation’s side;
- Build structural support for cylindrical body;
- Lift the hopper silo’s cylindrical body onto the structural support;
- Install cones with slopes under cylindrical body.
