Product Description
Large Span Steel Frame Greenhouse for Agricultural Seedling Production
Introduction
Optimize your agricultural production with our Large Span Steel Frame Greenhouses, specifically engineered for professional seedling nurseries and high-yield cultivation. Unlike traditional structures, our steel frame building system utilizes a column-free design (up to 30m span), providing maximum interior space for automated sprinkler systems and rolling benches. Built to withstand high humidity, every component of the steel frame undergoes a rigorous hot-dip galvanization process, ensuring superior rust resistance and a lifespan of over 20 years in moist agricultural environments.
Key Features
- Robust Steel Frame Structure: Fabricated from high-quality Q235/Q355 carbon steel with industrial-grade galvanization (275g/m² zinc coating), preventing corrosion from humidity and fertilizers.
- Maximized Light Transmission: The scientifically designed steel frame minimizes shadow areas, ensuring seedlings receive uniform sunlight for consistent growth.
- Column-Free Efficiency: The large clear span design eliminates internal obstacles, allowing for the unrestricted movement of tractors, AGVs, and boom irrigation systems.
- Customizable Environmental Control: The sturdy steel frame easily supports heavy equipment like cooling pads, exhaust fans, and automated shading screens.
