About the importance of window and door hardware, discussing their selection criteria, performance requirements and maintenance methods to enhance the performance and longevity of windows and doors.
In many cases, people are often misled by the word "matching" of accessories, forming the misconception that door and window hardware accessories are merely "supporting roles" or "insignificant". In fact, within the framework of doors and windows, hardware accessories are the heart, crucial for supporting performance. Quality doors and windows require a complete set of hardware accessories, such as hinges, handles, connecting rods, wind braces, pulleys, bolts, and door closers. Hardware costs can account for 15% to 30% or even more of the overall cost of doors and windows.
The Imapct of Hardware Quality on the Lifespan of Doors and Windows
The longevity of doors and windows is determined not only by the profiles but also by the quality of the hardware itself. Any door or window has a certain service life; the longer the usage (experiencing wind, rain, sun, daily wear and tear), the more severe the wear and aging of the doors and windows.
How Hardware Affects the Lifespan
When the hardware accessories that support the normal operation of doors and windows are damaged, broken, rusted, or aged due to improper use or prolonged use, the actual function of the doors and windows will be significantly weakened, and safety hazards will arise. At this point, we need to repair and maintain them or replace them with new ones. Generally, hardware components that are in normal use or well-maintained can last around 10 years.
Hardware Accessories are Directly Linked to Performace
The comprehensive performance of doors and windows is closely related to the types of hardware structures used. For instance, the load-bearing accessories of a casement window include hinges and sliding braces, which ensure the normal opening of the window, keep the sash stable in daily use or windy conditions, and improve the wind pressure resistance and stability of the whole window.
Locking Components
The locking components of doors and windows include locking points, locks, actuators, and corner devices. In conjunction with the sealing system, these hardware components significantly impact overall performance of doors and windows, including anti-theft, sealing, sound insulation, and thermal insulation. Additionally, by changing the position of the handle, door and window handles and interlocks can acheive various opening functions.
The "Five Questions and Five Answers" for Door and Window Hardware Accessories
1. What does "hardware" refer to in the context of doors and windows?
Door and window hardware is a general term for metal and non-metallic accessories used on building doors and windows. Their function is to help doors and windows open and close better and improve the overall performance, especially safety. Door and window hardware includes door locks, handles, braces, hinges, door closers, latches, anti-theft chains, and automatic door devices.
2. What conditions should door and window hardware meet besides physical and mechanical properties?
· Easy to operate, single-point control.
· Standardization and serialization for quick installation.
· Adjustability.
· Strong load-bearing capacity.
· High safety.
· Widely application.
· Strong applicability.
3. How to choose high-quality, high-performance door and window hardware?
· Select products with guaranteed quality and high brand awareness. The quality level of hardware should match the quality level of the doors and windows. The structure and shape should match the profiles, with coordinated and attractive colors, correct functions, flexible operation, and easy installation.
· Installation should be complete, standardized, reliable, and accurately positioned. After installation, the doors and windows should look beautiful, open and close flexibly, and should not deform, obstruct, or collide.
· Prefer stainless steel for exposed fasteners (e.g., a good handle should have a soft color, weak metallic glare, and even, delicate texture).
· Use multiple locking points for side-hung doors and windows and large sliding doors and windows to ensure their tightness under negative pressure. For convenience, it is best to use a multi-lock point handle or actuator.
4. What are the performance requirements for high-quality sliding braces?
· Opening and closing force: The sliding brace for internal and external casement windows should not exceed 40N, and for external top-hung windows, it should not exceed 40N within the 0-300mm opening range.
· Repeated opening and closing: Windows must undergo 25,000 opening and closing cycles. After 25,000 cycles, the opening and closing force should not exceed 80N to be qualified.
· Sliding brace strength (bearing weight on the sash): After opening the sash (or to its maximum position), the sliding brace must withstand a 1000N pressure (equivalent to 102kg) for five minutes. If all components remain intact, the sliding brace is a qualified product.
5. How can proper maintenance ensure a longer service life of door and window hardware?
· Clean stainless steel handles and other stainless steel hardware with a cleaner to increase brightness.
· Apply one or two drops of lubricating oil to moving parts like hinges, lifting wheels, and pulleys every six months to maintain smoothness.
· Pay attention to the rotation and extension direction of handles, avoid using force, and teach children not to hang or swing on handles to prevent danger and damage.
· If the lock cylinder is not turning smoothly, lightly blow some pencil core powder into the lock hole instead of using lubricating oil, which can attract dust.
Choosing the right door and window hardware accessories and maintaining them properly can significantly extend the lifespan of doors and windows, enhance performance, and ensure safety and stability in daily use.
