Step-by-Step Installation & Operation Guide

1. Project & Design Consultation: Discuss greenhouse specifications (span, height, number of bays) and environmental conditions to confirm the optimal multi-span arch frame design.
2. Main Frame Installation: Install the hot-dip galvanized steel columns, arch tubes, and longitudinal braces to form the primary Greenhouse Load Bearing Structure. Connect multi-span units with integrated gutters that provide both load-bearing and drainage functions.
3. Secondary Frame Assembly: Install the galvanized steel purlins horizontally between the arch tubes to enhance roof support and create a smooth surface for the film covering.
4. Connection System Setup: Use the hot-dip galvanized channels, film clamps, and bolts to assemble all components seamlessly, avoiding welding points that could rust.
5. Frame Calibration & Testing: Verify the structural integrity and alignment of the frame, checking the gutter system for proper drainage and the overall structure for wind and snow load capacity.
6. Film Cover Installation: Proceed with installing the plastic film covering, supported by the fully assembled Durable Agricultural Frame Structure.
