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.
