Classification and importance of door and window hardware accessories
Hinges: As the key component connecting the door and window sashes and window frames, the quality of hinges directly affects the smoothness of the opening and closing of doors and windows. High-quality hinges are usually made of stainless steel or copper, with strong load-bearing capacity, which can ensure that doors and windows will not deform after long-term use. Hinges made of 304 stainless steel have good rust resistance and are suitable for all kinds of environments.
Handles: Not only are they the focus of door and window operation, but they also affect the aesthetics of doors and windows. Common ones include handles and rotary handles. Aluminum alloy handles are sturdy and durable, with anodized surfaces, wear-resistant and not easy to fade; while zinc alloy handles have various shapes and can meet the needs of doors and windows of different styles.
Locks: They are related to the safety performance of doors and windows. Mechanical locks such as pin locks and blade locks have undergone long-term development and mature technology; smart locks rely on fingerprint recognition, password unlocking and other functions to bring users convenience and high-tech experience.
Pulleys: They are crucial for sliding doors and windows. Nylon pulleys have good mute effects, while stainless steel pulleys are high in strength and wear-resistant. In heavy sliding doors, pulleys with large load-bearing capacity should be selected to ensure smooth sliding.
Hinges: Similar to hinges, but widely used in some heavy doors and windows or specially designed doors and windows. Hidden hinges make the appearance of doors and windows simpler and improve the overall aesthetics.
Selection points
Material: In addition to the stainless steel, copper, aluminum alloy, and zinc alloy mentioned above, there are also carbon steel, plastic and other materials. Carbon steel has high strength, but it is easy to rust and needs to be rust-proofed; plastic material has low cost and is mostly used for some indoor doors and windows that do not require high strength. In humid environments such as the seaside, corrosion-resistant 316 stainless steel accessories should be preferred.
Brand and quality certification: Passing ISO9001 quality management system certification, European Door and Window Hardware Association certification, etc. is an important sign of product quality compliance.
Adaptability: Door and window hardware accessories must match the type of doors and windows (casement windows, sliding windows, casement doors, sliding doors, etc.), size, and profile. For example, aluminum doors and windows with broken bridges need to be matched with hardware accessories to achieve their best performance.
Performance indicators: Pay attention to the load-bearing capacity, wind pressure resistance, air tightness, water tightness and other indicators of hardware accessories. For example, doors and windows of high-rise residential buildings need to use hardware accessories with strong wind pressure resistance to ensure safety.
