Door fitting is a crucial aspect of both residential and commercial construction. It involves selecting, aligning, and installing various components such as hinges, locks, handles, stoppers, door closers, and bolts to ensure that a door operates smoothly, fits securely, and complements the design of the space. The foundation of proper door fitting begins with accurate door measurements and the right selection of hardware. Hinges are the most basic yet vital fitting, enabling the door to pivot. High-quality stainless steel or brass hinges resist rust and last longer, especially in exterior applications. For interior doors, concealed or butt hinges are popular for their neat appearance. Locks and handles not only provide functionality but also security. Mortise locks, deadbolts, and cylinder locks are commonly used in main doors for better protection, while tubular latches and privacy locks are often chosen for bedrooms and bathrooms. Door handles come in various styles—lever, knob, or pull—offering both ergonomic use and aesthetic value. In modern interiors, door closers and soft-close mechanisms are increasingly popular for smooth, noise-free operation. Floor springs and patch fittings are used extensively in glass doors in offices or showrooms for a sleek, frameless look. Other fittings like door stoppers, flush bolts, and peepholes add convenience and safety. Choosing the right materials—aluminum, stainless steel, zinc alloy—ensures durability and resistance to wear. A well-fitted door enhances both the functionality and appearance of any space. Improper fitting can lead to gaps, noise, difficulty in operation, and even reduced security. Therefore, investing in quality fittings and professional installation is essential.
