S-SEN Greenhouse Vent Window Hinge is the core hardware connecting greenhouse ventilation window sash and frame, realizing flexible rotation and stable positioning of sashes via sophisticated mechanical structure. As a professional manufacturer focusing on greenhouse hardware R&D and production, S-SEN integrates high-quality materials and precise craftsmanship into each hinge, ensuring adaptability to greenhouse environments. Produced in our factory in China, it features strict quality control and perfect after-sales service, becoming a trusted supplier for global greenhouse operators.
T-SEN Greenhouse Vent Window Hinge is specially developed for harsh greenhouse environments (high humidity, large temperature difference, frequent wind), solving the pain points of traditional hinges such as easy rust and unstable load-bearing. As an experienced manufacturer, we adhere to "quality first, adaptability first", ensuring our hinges match various greenhouses. Our factory in China relies on mature industrial chains to realize mass production with stable quality, serving as a reliable global supplier of greenhouse hardware.
As the core component of greenhouse ventilation windows, S-SEN Vent Window Hinge has the following key functions:
- Window Sash Support: Stably bears sash weight and wind force, avoiding sash deformation and ensuring long-term use.
- Opening Angle Control: Supports 0-90° adjustment (180° for some models), meeting different ventilation needs to regulate greenhouse temperature and humidity.
- Safety Protection: Equipped with anti-drop structure to prevent accidental sash falling and avoid safety accidents.
- Environmental Adaptability: Adopts corrosion-resistant materials and special surface treatment, withstanding harsh greenhouse environments without easy rust or failure.
S-SEN adheres to strict technical standards, with the following core indicators for vent window hinges:
- Material: Mainly 304/316 stainless steel (316 for corrosion-resistant environments), auxiliary parts made of high-strength aluminum alloy; stainless steel tensile strength ≥520MPa.
- Load Capacity: 20-100kg (by model), matching small, medium and large ventilation windows.
- Opening Angle: 0-90° (180° flip opening for some special models).
- Service Life: 5-10 years under normal maintenance, reducing replacement and maintenance costs.
- Surface Treatment: Polishing/passivation treatment, enhancing corrosion resistance and appearance, easy to clean.
- Structural Design: Dual-axis locking + locking pin anti-drop structure, strengthening safety and preventing high-altitude falling.
1. Standard Hinge-Type Hinge
With simple structure, easy installation and low cost, it is suitable for small manual ventilation windows. It has stable load-bearing but no independent positioning function, requiring matching with other positioning devices.
2. Friction Hinge
Medium and high-end product with built-in damping structure, realizing arbitrary angle positioning without additional devices. It has strong load-bearing capacity, suitable for large ventilation windows. Representative products: 90° Positioning Slide Support, 180° Flip-up Slide Support.
3. Torque Hinge
High-safety product for high-rise or heavy-duty ventilation windows, with constant torque to stably maintain any opening angle. Equipped with anti-drop design, made of high-strength 304/316 stainless steel, suitable for harsh scenarios.
