Window and door friction stays play a crucial role in supporting and adjusting the opening and closing of windows and doors. Therefore, selecting the right material is essential. Below, we explore the key material requirements for friction stays.
1. Excellent Corrosion Resistance
Friction stays must have excellent corrosion resistance. Rust can hinder smooth movement, reduce the overall performance of windows and doors, and weaken the mechanical strength of the stays. In severe cases, this may lead to window deformation, detachment, or even safety hazards. Therefore, corrosion resistance is the primary consideration when selecting friction stay materials.
2. Use of High-Grade Stainless Steel
Stainless steel is the ideal material for friction stays due to its high corrosion resistance and strength. However, different stainless steel grades vary in performance. It is recommended to use 300-series stainless steel or higher, such as 304 stainless steel, which offers superior durability in various environments. In contrast, lower-grade stainless steels like 201 and 202, though more affordable, have poor corrosion resistance and tend to rust in humid or saline environments, significantly reducing the lifespan of the friction stay.
3. Appropriate Thickness
The thickness of friction stays directly affects their load-bearing capacity. For heavier window sashes, it is advisable to use stays with a thickness of at least 2.5mm to ensure stability and reliability, preventing deformation or detachment caused by insufficient load capacity.
Conclusion
High-quality friction stays should feature excellent corrosion resistance, high strength and toughness, and appropriate thickness to ensure the stability and safety of windows and doors. Choosing the right friction stay material is key to enhancing the longevity and security of windows and doors.
