How To Choose The Hinge

The hinge plays an important role in the doors and windows. If the quality of the hinge is poor, the doors and windows will be easy to stagger forward and back after long use, and finally loose and sagging. High-quality hardware is always made by cold-rolled steel in one-time stamping molding. It feels solid, and the surface is smooth. Moreover, because of the thick surface coating, high-quality hardware with stronger bearing capacity is durable and not easy to rust. The inferior hinge is generally welded by thin steel sheet, which has almost no rebound. After a long time use, the hardware will lose elasticity, resulting in looseness of doors and windows, and even cracking.

The hinge with different quality feels different. Open the door or window, the ones with high-quality hinge will be on the softer release, and when closed to 15 degrees, the door or window will automatically rebound with very uniform resilience. Choosing hinge, you should pay attention to the reset property of the spring hinge. The quality of the reed also determines the opening angle of the doors and windows. Good reed can make the open angle of doors and windows greater than 90 degrees. You can open the hinge to 95 degrees, push down both sides of the hinge and observe the supporting spring reed. If there is no distortion and break, the products generally have good quality.
