Greenhouse Door Hinge, manufactured by S-SEN Metal in China, is a core load-bearing hardware component for greenhouse systems. Designed specifically for agricultural greenhouses, livestock greenhouses, and multi-span greenhouses, it features high load-bearing capacity, strong corrosion resistance, strong wind resistance, and easy installation. It stably supports the long-term smooth operation of greenhouse doors and is a reliable hardware component for greenhouse projects worldwide.
Greenhouse door hinges are crucial connecting components between the greenhouse door and frame, bearing core functions such as load-bearing, rotation, sealing, and wind resistance, directly impacting the door's lifespan and user experience. We strictly adhere to production standards, selecting metal materials suitable for various environments, and employing precise structural design to ensure stable operation under complex conditions such as humidity, high salt spray, and strong winds, making them suitable for installation in various commercial and industrial greenhouses.
S-SEN Metal specializes in the R&D and manufacturing of greenhouse hardware. Our Greenhouse Door Hinge series covers two main categories: bearing hinges and top and bottom hinges, with a complete set of auxiliary accessories, supporting standardized installation and customized modifications.
1. Bearing Hinge
The S-SEN Bearing Hinge features a built-in double ball bearing structure, replacing sliding friction with rolling friction. This results in smoother opening and closing, less wear, and a longer lifespan, making it the core mainstream style for Greenhouse Door Hinges.
Material Standard: ≥2.5mm hot-dip galvanized steel pipe for standard environments; 304 stainless steel with a tensile strength ≥520MPa for high humidity/coastal areas.
Load Capacity: A single hinge can bear 150–200kg. It is recommended to install 3 hinges per door to ensure the door does not deform or sag.
Applicable Scenarios: Suitable for standard width greenhouse doors, light/medium-duty metal doors, PVC doors, and other standard door types. Suitable for most small and medium-sized greenhouse projects.
2. Sky and Earth Axis Hinge
The Sky and Earth Axis Hinge features a design with evenly distributed force at both the top and bottom pivot points, effectively preventing sagging, jamming, and deformation of wide-body doors. It is an exclusive Greenhouse Door Hinge style for large-size greenhouse doors.
Force Structure: The upper and lower axles bear weight synchronously, resulting in a larger load-bearing area and stronger stability, preventing door misalignment after long-term use.
Applicable Scenarios: Suitable for heavy-duty iron doors, solid wood-filled doors, and main entrance doors of large greenhouses (width > 1.2m), and for large multi-span greenhouses, ecological restaurant greenhouses, and other similar scenarios.

We provide a complete set of matching hardware for the Greenhouse Door Hinge, eliminating the need for additional purchases, improving installation efficiency and operational stability, and comprehensively ensuring the safety of door operation:
1. Door Ball: Double ball bearing structure with a buffer stroke ≥ 8mm, reducing closing impact and noise, and protecting the connection between the Greenhouse Door Hinge and the door body.
2. Shaped Clamp: Hot-dip galvanized material, ≥30mm wide, reinforces the connection between the hinge and the door/frame, improves overall wind resistance, suitable for greenhouses in windy areas.
3. Door Corner Protector: ≥1.5mm thick galvanized sheet, duckbill design, fits tightly to the door corner, protects the door edge while enhancing the installation stability of the Greenhouse Door Hinge.
