Welded Silo

Storing grain is more than finding an empty space after harvest. Moisture, heat buildup, insects, and poor ventilation can quickly affect quality and reduce market value. A storage system should not only hold grain safely but also make loading, monitoring, and unloading more efficient.

COBAN manufactures welded steel silos for customers who require permanent grain storage with high structural strength and dependable performance. Every silo is produced from heavy steel plates in our factory, delivered in sections by container, and welded together at the project site. This approach keeps transportation practical while creating a solid storage structure once installation is complete.

Our welded silos are widely used by grain processors, feed manufacturers, rice mills, flour mills, agricultural cooperatives, and government grain reserve projects. From a single storage unit to a complete grain handling facility, every solution is designed around the customer’s actual operating requirements.

Why Choose a COBAN Welded Steel Silo?

A Permanent Storage Solution

A welded silo is intended for projects where long service life is important. Once assembled and welded on-site, it becomes a permanent part of the grain storage facility and requires very little routine maintenance.

Protects Grain Quality

Good storage conditions help reduce moisture absorption and minimize the risk of mold or insect activity. When combined with aeration and temperature monitoring equipment, the silo provides a stable environment for grain preservation.

Strong Steel Structure

The silo body is manufactured from structural steel plates with reinforcing components designed according to storage capacity and local environmental conditions. The finished structure is suitable for continuous operation throughout the year.

Flexible Project Design

No two grain projects are exactly alike. COBAN engineers design each welded steel grain silo according to the customer’s grain type, required capacity, available land, loading equipment, and future expansion plans.

Easy to Transport Worldwide

Instead of shipping oversized finished tanks, all steel components are packed into containers. After arriving at the destination, the silo is assembled and welded directly on the prepared foundation, making international transportation much more economical.

What Is a Welded Grain Silo?

A welded grain silo is a vertical steel storage structure built from flat steel plates that are joined together by welding during installation.

Unlike corrugated silos connected with bolts, the completed shell forms one continuous structure. This design offers excellent rigidity and is often selected for projects where grain will remain in storage for extended periods.

The vertical design also allows customers to store more grain while using less land compared with conventional warehouse storage.

Suitable Materials

Although welded silos can store many bulk materials, COBAN mainly designs them for agricultural applications.

Capacity Options

Every storage project begins with understanding how much grain needs to be stored throughout the year.

COBAN can manufacture welded silos in a wide range of sizes.

Custom dimensions are available for special projects.

How Grain Moves Through the System

After cleaning, grain enters the storage system through a bucket elevator or conveyor.

A distributor installed at the roof spreads grain evenly inside the silo. During storage, ventilation equipment maintains air circulation while monitoring devices record grain temperature. These systems help operators detect changes before grain quality is affected.

When grain is required for processing or shipment, discharge equipment transfers it smoothly to conveyors, trucks, or processing lines.

Because all equipment works together, the storage process becomes safer, cleaner, and more efficient.

Supporting Equipment

A welded silo normally works together with several handling systems.

Customers may purchase only the silo or a complete turnkey grain storage system.

Practical Advantages

Customers often select welded steel silos for the following reasons:

• Suitable for long-term grain storage.
• Excellent sealing helps keep stored grain dry.
• Strong steel structure supports large storage capacities.
• Occupies less land than conventional warehouses.
• Easy to integrate with conveying and monitoring systems.
• Supports future expansion of grain handling facilities.
• Designed for continuous industrial operation.
• Lower maintenance requirements over the long term.

Welded Steel Silo vs Corrugated Steel Silo

Both products are widely used in agriculture, but they serve different project requirements.

For grain reserve projects and permanent processing facilities, many customers prefer welded structures because of their stability and sealing performance.

Industrial Welded Storage Silo

Compared with Concrete Storage

Steel welded silos have gradually replaced concrete storage in many agricultural projects.

The shorter construction period also allows customers to begin operation sooner.

From Factory to Installation

Every COBAN welded silo follows a carefully controlled production process.

Steel plates are inspected before fabrication. Components are then cut, rolled, and prepared for shipment. After protective surface treatment, everything is packed into containers for international delivery.

At the customer’s site, our installation team assembles every section, completes all welding work, and carries out final inspections before the storage system enters operation.

Shipping Method

Large welded silos are not transported as complete units.

Instead, wall plates, roof sections, stiffeners, ladders, platforms, and accessories are packed separately to maximize container space and reduce transportation costs.

Once delivered, all parts are assembled and welded on the prepared foundation according to the engineering drawings provided by COBAN.

Typical Applications

COBAN welded grain silos are commonly installed in:

• Grain collection centers
• Rice mills
• Feed pellet plants
• Flour processing factories
• Seed processing facilities
• Grain reserve stations
• Grain trading companies
• Agricultural cooperatives
• Port grain terminals
• Large-scale farms

Why Customers Work with COBAN

Every storage project presents different technical challenges.

Rather than supplying standard products, COBAN works with customers from the planning stage to develop storage systems that fit their production process, site conditions, and future development goals.

Our services include engineering design, manufacturing, shipping, installation guidance, commissioning, operator training, and ongoing technical support.

Many of our customers return when expanding their facilities because the equipment continues to perform reliably after years of operation.

How Pricing Is Determined

The cost of a welded steel silo depends on several project-specific factors rather than capacity alone.

These include storage volume, steel specification, local climate, roof structure, discharge method, automation level, supporting equipment, shipping destination, and installation requirements.

Providing basic project information allows our engineers to recommend the most suitable solution and prepare an accurate quotation.

Technical Support After Delivery

COBAN continues providing technical assistance after installation.

Customers receive support with commissioning, equipment operation, maintenance planning, spare parts supply, and troubleshooting whenever required.

Our objective is not simply to deliver a silo, but to help customers build a grain storage system that continues operating efficiently for many years.
