Different Types of Hinges for Doors and Windows

Doors and windows rely on professional hinge hardware to achieve flexible opening, stable closing and long-term structural balance. Different door and window scenarios require different hinge structures. Using the wrong type of hinge will cause sagging, noise, loose rotation, or even window falling risks. In architectural hardware applications, four types of hinges are the most widely used: butt hinge, butterfly hinge for door installation, and window hinge, window stay for casement window systems.

Two Main Hinge Types for Doors

1. Butt Hinge

The butt hinge is the most traditional and universal door hinge, widely used for all kinds of wooden doors, steel doors, fire doors and interior room doors. It consists of two metal leaves and a central pin shaft. When the door closes, the two leaves butt tightly together to ensure flat and neat door closure.

Manufactured with thickened stainless steel or iron materials, butt hinges feature strong load-bearing capacity, anti-deformation performance and ultra-long service life. With smooth rotation and low failure rate, they can withstand tens of thousands of opening and closing cycles. Standard butt hinges are the preferred hardware for engineering decoration, apartment renovation and commercial building door systems.

Best Application: Household interior doors, office doors, hotel doors, fire-rated doors, wooden and metal swing doors.

2. Butterfly Hinge

Butterfly hinges, also known as flower hinges, feature a unique double-wing symmetrical structure, just like butterfly wings. Compared with traditional butt hinges, butterfly hinges are more beautiful, lightweight and easy to install without complicated mortising work.

This hinge can be mounted on the door surface directly, saving installation time and avoiding damage to the door panel. Its flexible rotation brings silent opening and closing experience. With delicate appearance and various surface finishes, butterfly hinges greatly improve the overall decoration effect of indoor doors.

Best Application: Lightweight interior wooden doors, cabinet doors, bedroom doors, villa decoration doors, and decorative-style door projects.

Two Main Hinge Types for Windows

1. Window Hinge (Casement Window Hinge)

Window hinges are specially designed for side-hung casement windows. Different from door hinges, window hinges adopt narrow long structural design, which is more suitable for thin window frames and lightweight window sashes. They support stable left and right opening and closing of aluminum windows, wooden windows and plastic steel windows.

High-quality window hinges effectively avoid window shaking, sagging and wind shaking problems. With anti-rust and corrosion-resistant performance, they adapt to long-term outdoor wind and rain exposure, ensuring smooth window operation throughout all seasons.

Best Application: Residential casement windows, aluminum alloy windows, plastic steel windows, building exterior windows, conventional side-opening windows.

2. Window Stay

Window stay is a functional window hardware that combines support, limit and anti-fall functions. While realizing window rotation, it can fix the window at any opening angle to prevent excessive swing caused by wind force. It is an essential safety accessory for modern building windows.

Window stays adopt multi-link linkage structure, featuring flexible angle adjustment, strong bearing stability and wind resistance performance. They can effectively prevent window sash falling off, improving building window safety. All Degol window stays pass strict load testing and salt spray testing, suitable for long-term outdoor use.

Best Application: High-rise building windows, outward opening windows, bathroom windows, kitchen windows, safety-protection window projects.
