Application of Stainless Steel Rivets in Window and Door Systems

I. Core Materials and Processes

• High-strength alloys: High-grade zinc alloy, aluminum alloy or stainless steel (cast / forged) should be used for high-quality handles, transmission rods, lock keepers and other key components. These materials feature a dense internal structure and high strength, and are not easy to deform or break after long-term use.
• Key load-bearing components: Load-bearing arms and connecting shafts of hinges must be made of stainless steel (such as 304 stainless steel). The strength and corrosion resistance of stainless steel are essential to ensure that sashes do not sag and operate smoothly for many years.

II. Structural Design and Load Capacity

• Multi-point locking design: The more lock points (such as three-point, five-point or more), the more uniform the locking surface between the sash and the frame when closed, resulting in better sealing performance and stronger resistance to wind pressure deformation.
• Lock point / lock keeper structure: Hook-shaped or mushroom-shaped lock points matched with robust metal lock keepers are recommended. This design effectively resists wind pressure when locked and prevents the sash from being “sucked open” or “blown open”, with far better durability and safety than simple fork-shaped lock points.

• Transmission rods: Made of solid steel with internal reinforcing ribs to ensure no deformation or jamming during repeated operation.
• Handles: Internal multi-tooth precision gear structure, with clear and smooth rotation without backlash. Inferior handles have thin internal gears, which are prone to wear, leading to loosening or even falling off.

III. Details of Key Components

• Bearings: High-quality sliding bearings or needle roller bearings must be used, which are the key to silent, smooth and long-lasting opening and closing. You can test by repeatedly opening and closing a sample window to check if it is light, uniform and free of jamming.
• Adjustability: High-quality hinges feature three-dimensional adjustment (up/down, left/right, front/rear), allowing fine-tuning of sash position during installation and after long-term use to compensate for settlement or deformation and ensure long-term sealing.

• All screws and rivets connecting the frame / sash must be made of stainless steel to prevent rust seizing and facilitate future maintenance.
• Connections between hardware and profiles shall be firm and free of looseness.
