Why Plain Joint Door Hinge used in Light Duty Door?
Load-bearing capacity adapted to lightweight door requirements
The flat hinge achieves door opening and closing through the rigid connection between the face plate and the shaft, with structural strength sufficient to support the weight of lightweight doors (such as interior doors and cabinet doors). Compared to double-sided hinges, flat hinges have stronger load-bearing capacity, effectively preventing issues like sagging or deformation of the door panel due to prolonged use.
Simple in structure, cost-effective
The hinge consists of a flat plate and a shaft, featuring no complex buffering or spring mechanisms, with low material costs and ease of mass production. Its installation method (fixing the door frame and door leaf with screws) requires no special tools, further reducing overall costs, making it suitable for lightweight doors with economic requirements.
Installation convenience enhances user experience
Although the surface of the hinge will be partially exposed after installation, the process is relatively simple and does not require precise cutting of the door frame or door panel. For lightweight doors, the exposed portion has minimal impact on aesthetics, while the improved installation efficiency can shorten the construction period, meeting the demand for rapid deployment of lightweight doors.
Durability meets the requirements for lightweight door usage scenarios
Light-duty doors typically have a lower frequency of opening and closing, requiring less wear resistance from hinges compared to heavy-duty doors. Flat hinges made of metal materials (such as stainless steel or galvanized steel) can resist daily wear and tear, require infrequent maintenance, and offer lower long-term usage costs.
Functional positioning aligns with the requirements of lightweight doors
Hinged doors provide basic opening and closing functions without additional features such as damping or automatic closing. For lightweight doors, these functions are not essential, and the simple design of hinged doors aligns perfectly with their "function-first" positioning, avoiding resource waste.
