Hinges, Locks & Handles — Complete Guide
Hinges, locks and handles are the core architectural hardware that make doors & windows functional, secure and aesthetic. Hinges allow swing movement, locks provide security, and handles enable operation. The right hardware — correct type, material (stainless steel / brass / zinc), finish and load rating — ensures smooth operation, durability and security for decades. They are used on every door, window, cabinet and wardrobe in a building.
Indian door hardware follows IS 12817 (Stainless Steel Butt Hinges), IS 205 (Non-Ferrous Hinges), IS 2209 (Mortice Locks). Major brands: Godrej Locks, Dorset, Hettich, Hafele, Ozone, Yale, Europa, Harrison, Ebco, Kich.

Conclusion
Quality hinges, locks & handles are essential for smooth, secure, durable doors & windows. Use SS 304 hinges (3–4 per door, ball-bearing for heavy), good mortise / digital locks for security, and brass / SS in coastal areas. Match finishes across the home and buy genuine branded products. Don't cut corners on hardware — cheap rust-prone fittings fail and cause doors to sag.
These work alongside latches & tower bolts, are fixed with screws & anchor bolts, and complete the door / window assemblies. For door materials, see the Doors & Windows category.
