Installing Greenhouse Frame Pins: Ready for a New Growing Season
​Securing the connectors of a greenhouse structure is a vital preparatory step to ensure it can withstand wind loads and the weight of crops throughout the upcoming season.
​1. Locking Mechanism and Structural Stability
Frame pins (often spring pins or clevis pins) act as the "joints" between the arches and the main pillars. A close-up of this process emphasizes the importance of a snug fit. Loose pins allow wind vibrations to cause metal fatigue, which could lead to structural failure. Replacing rusted pins ensures that the skeletal system functions as a unified, rigid block.
​2. Tensioning Support and Snag Prevention
In many designs, these pins also serve as anchor points for spring wires (zigzag wires) used to tension the plastic film. Technicians must ensure the pins are driven flush, with no sharp edges that could tear the PE film as it expands or contracts with temperature shifts. Precision here results in a drum-tight surface that optimizes light transmission for the plants.
​3. Seasonal Maintenance and Durability
Installing pins is the perfect opportunity to recalibrate the alignment of the entire greenhouse range. Using galvanized or stainless steel pins protects against the high humidity common in growing environments. A tightly pinned frame provides the necessary foundation for overhead irrigation, supplemental lighting, and automation systems for a successful harvest. #GreenhouseConstruction #building
