According to materials, door and window hinges include metal hinges and plastic hinges, among which metal hinges include iron hinges, stainless steel hinges, aluminum alloy hinges, etc.
The concealed hinge is completely hidden within the space enclosed by the frame profile when the window sash is closed, and the installation of hardware does not require damaging the sealing strip. It retains the sealing of the complete closed-loop connection of the sealing strip, thereby improving the overall sealing and insulation of the window.
Surface mounted hinges, exposed outside the profile, require cutting the sealing strip before installing hardware accessories, which can damage the integrity of the sealing strip and affect the sealing and insulation performance of the entire window.
The opening angle of mainstream concealed hinge hardware window sashes is generally between 90 ° and 110 °, and most cannot reach 180 °. However, surface mounted hinge hardware window sashes can easily achieve 180 ° opening. When there is a need for 180 ° opening, choosing surface mounted hinges will be more suitable.
