Why Hinges Are More Important Than You Think
While handles and locks often get the spotlight, hinges quietly carry the heaviest responsibility—literally. A door hinge must support the weight of the leaf, ensure smooth movement, and maintain alignment for years. Choosing the right hinge is a technical decision that directly impacts safety and durability.
Contractors who start with dependable hardware from a trusted Door Handle Manufacturer minimize risks of premature failure or costly adjustments.
Understanding Load Ratings
Light-Duty Hinges: Suitable for interior doors under 20 kg.
Medium-Duty Hinges: For office or retail doors up to 40–50 kg.
Heavy-Duty Hinges: Required for entrance doors or high-traffic zones exceeding 80 kg.
Always match hinge capacity with door size and frequency of use.
Bearing Types and Their Benefits
✔ Plain Bearing Hinges: Economical, best for light traffic residential use.
✔ Ball-Bearing Hinges: Reduce friction, ideal for heavy doors and frequent use.
✔ Concealed Hinges: Provide a clean aesthetic but may require specialized installation.
Door Alignment and Installation Tips
Use three hinges for doors over 2100 mm in height.
Place the third hinge slightly above center for optimal weight distribution.
Shim hinges carefully to maintain plumb alignment and prevent sag.
Builders often choose tested products from Door Hinge Manufacturer to guarantee proper load handling and smoother long-term performance.
Common Mistakes to Avoid
❌ Using light-duty hinges on heavy entry doors
❌ Ignoring bearing type in high-traffic projects
❌ Failing to adjust during seasonal door expansion/contraction
Final Thoughts
Hinges may be small, but they’re fundamental to door system performance. By understanding load ratings, selecting the right bearings, and ensuring proper installation, contractors can avoid costly callbacks and extend the lifecycle of every project.
