The basic structure of our steel barn

Main frame

Our steel structure warehouse (steel barn) uses ASTM A572 Gr50 high-strength steel (yield strength ≥345MPa) as the main supporting material, which has excellent earthquake and wind resistance, adapts to various environmental conditions, and ensures long-term and stable use of the warehouse.

Walls and roofs

The walls and roofs are covered with double-sided 275g/m² hot-dip galvanized steel plates or color steel plates, which have excellent anti-rust and anti-corrosion properties. 

The thickness of the galvanized layer exceeds the ISO 1461 standard by 2.1 times, which greatly enhances the durability of the material, extends its service life, and can resist severe weather, chemical corrosion and other environmental influences.

Our Metal Barn types

We provide a variety of design solutions to meet different site requirements and usage functions. Common steel structure warehouse designs include:

1. Classification by purpose

Agricultural Steel Barns: Mainly used for storing grain, feed, agricultural machinery and equipment, etc., characterized by a large span, equipped with a good ventilation system to prevent grain from getting damp, and optional insulation layer to regulate the internal temperature.

Livestock Steel Barns: Used to raise livestock, such as cattle, horses, sheep, etc., the design focuses on ventilation and drainage systems to ensure the comfort of livestock, facilitate cleaning and maintenance, and reduce the risk of disease transmission. Optional insulation layer to adapt to extreme climates.

Storage Steel Barns: Used to store goods, equipment or other items. It is characterized by large space and solid structure to ensure the safety of stored items, and can customize compartments or shelves according to needs.

Multi-Purpose Steel Barns: Can be used for a variety of purposes such as garages, workshops, exhibition halls, etc. Flexible design, strong adaptability, optional doors, windows, lighting and other facilities to improve convenience.

2. Classification by structural design

Single Slope Steel Barns: The roof is tilted to one side, which is convenient for drainage. The structure is simple and the cost is low. It is suitable for small farms or storage purposes.

Gable Steel Barns: The roof is triangular and symmetrical on both sides, providing a larger internal space. It is suitable for medium to large farms or storage purposes.

Quonset Steel Barns: The roof is semicircular, compact, and has excellent wind resistance. It is suitable for areas with harsh climates, and it is quick to install and low in cost.

Multi-Span Steel Barns: It consists of multiple spans, suitable for large farms or commercial purposes, providing a large internal space, suitable for storing large equipment or a large amount of goods, and can be expanded according to needs.

3. Classification by functional configuration

Standard Steel Barns: Basic configuration, suitable for general storage needs, low cost and quick installation.

Premium Steel Barns: Equipped with advanced features such as insulation, ventilation system, intelligent monitoring, etc., suitable for customers with high requirements for environment and safety.

Custom Steel Barns: Customized size, design and function according to customer needs, suitable for customers with special needs.

4. Classification by scalability

Fixed-Size Steel Barns: Fixed size, suitable for one-time needs, fast installation and low cost.

Modular Steel Barns: Supports later expansion, customers can increase area or function according to needs, suitable for customers who need flexible adjustment.

Advantages of our Steel Barn

• Durability: The high strength of steel and galvanized protection ensure long-term use of the product in harsh environments.
• Low maintenance cost: Almost no maintenance is required and it is not affected by pests, mold or corrosion.
• Quick installation: Prefabricated components and modular design greatly shorten construction time.
• Environmental protection: Steel is 100% recyclable, reducing the impact on the environment.
