For example if there is weak frame, then install the hinge onto the floor and ceiling might be one options. 

How Hinges differ and why are they important?

Key points when choosing which type of hinges can be looking at 3 perspectives: function, durability and installation enviroments.

 

Pivot hinge-Manual Motion Control : 

• Function - Only working as pivot point, the door only moves when outside force apply to the door. 
• Durability - This type of hinge design without high risk components such as spring or seal, there is a very long life cycle. 
• Installation environments – Residential: or Non-Self-Closing Zones Ideal for private homes    

Spring/ Pneumatic hinge- mandatory for climate control, privacy, or safety: 

• Function – A self close mechanism is included, usually spring driven or pneumatic gas spring inside to create force to assist door close at certain degree.
• Durability – Limited life cycle , normally 3~8 years depending on the design of the spring. Critical factors of the spring is material, shape & design, heat treatment. Door weight is highly related to the spring size, the higher weight of the door, the larger size of spring it requires.
• Installation environments – Self closing function is a must. Privacy & Professionalism is critical. Private offices, conference rooms, or medical clinics.
