Upgraded Heavy-Duty Galvanized Frame: The tunnel greenhouse has reinforced load-bearing posts made of thickened galvanized pipes (diameter: 1", wall thickness: 0.02"), which improves overall strength and stability. Reinforced door posts, added diagonal bars, U-shaped posts and anchors increase stability and protect your plants from rain, snow and strong winds.
Thick High Density PE Cover: This high tunnel greenhouse uses a high-quality 140g/m² PE plastic cover that is waterproof, sun-resistant and insulating, ensuring healthy plant growth. Double-stitched seams and reinforced window seams effectively prevent tearing. The extended PE cover edges can be folded down or buried in the ground to improve insulation, airtightness, humidity and temperature control.
Efficient Ventilation Design: The arch greenhouse is equipped with 16 windows and a side-opening door for optimal airflow. Velcro straps on the door and windows allow for easy adjustments, and the mesh netting helps keep small creatures out and protects plant health.
