Where are Stainless Steel Window Hinges used? - Material Requirements and Selection Basis of a Top Hung Window Friction Hinges.
The window friction hinge mainly supports and locates the doors and windows. Now many manufacturers use heavy duty concealed hinges to replace large friction hinges, but friction hinges still have an irreplaceable position in high-rise buildings.
1. Firstly, we would need to take a look at product's material requirements
The window friction hinge must be rust-proof, because rust will affect the smoothness of sliding, reduce the mechanical properties of the friction stay, and even may cause the hinge to break. To have good corrosion resistance, stainless steel materials above 300 series, such as 304 stainless steel, have high corrosion resistance and high strength and toughness. The stainless steel such as 201 and 202, has lower rust resistance than the 300 series, although the price is lower. In addition, the thickness of the friction hinges also affects the bearing capacity. When the sash is heavy, it is best to choose a sliding brace with a thickness of more than 2.5mm.
2. The selection of window friction hinge is determined according to the size of the window and the weight of the window:
First of all, the load-bearing of the sliding brace ≥ the weight of the window sash (the weight of the window sash profile + the weight of the glass) × the safety factor 1.3.
Also, to choose the length of the window friction hinge: Under normal circumstances, it is 2/3 of the window width. When the window is lighter, it can be 1/2 of the window width. When the friction hinge is selected for the top hung window, the length of top hung window hinge is generally 1/2 of the height of the window.
According to the actual situation, select the friction hinge that meets the above conditions at the same time. When selecting, you can check the friction stay product specifications and corresponding lengths in the specification table.
