Interior doors is anywhere in our daily life, they are used as building materials frequently, so the door hardware must strictly pass quality test. Consumers should pay more attention to the concept of green environmental protection, because there are many people choose and buy the aluminum alloy interior door. In addition to the quality of interior door, the door body and small hardware play an important role.

When we grab the door handle and it falls off, or when we turn the door lock of the bedroom door with the key, the key cannot be pulled out in the keyhole, we can imagine how embarrassed it is and it makes troubles. However, many people meet the problem in daily life. So we should realize that even if we purchase the best quality bedroom door, it is not useful if the hardware is with poor quality and not durable.

 

Do you know that Once hardware is used for long, the "creaking" sound is often heard when the door is opened and closed? Because the inferior quality hinge is mostly made of iron leaf and iron ball bearings, the material is easy to rust and fall off, then the hardware deform and loosen on the door.

From the appearance, most inferior quality hinge is made of iron with less than 3mm thick resulting in uneven coating and rough surface. The impurities, length, the whole position, spacing and other deviations do not meet decoration requirements. Moreover, the disadvantage of common hinge is that they do not have the spring function. After installing the hinge, it must be equipped with all kinds of ball bearings; otherwise, the door panel will be blown.

The high quality hinge is made of 304 stainless steel with thickness up to 3 mm. Uniform color and exquisite processing make the hinge heavy enough, fully thick and flexible turning, there is no "stuck" phenomenon. It looks delicate without burrs and sag. The hinge can be salt spray tested for 240 hours.

The core of the hinge is the ball bearing, the smoothness; comfort and durability are determined by the ball bearing.

The poor quality of hinge ball bearing is caused by iron leaf which are not durable, easy to rust and lack of friction, so the door will keep creaking when they are closed and opened. The high-quality hinge are with stainless steel precision ball bearings, high use-200000 test cycles, load bearing and in accordance with international standards. It guarantees flexibility and smoothness of opening doors in silence.

Therefore, when choosing to buy, you can try to feel whether the surface treatment and operation are smooth, , there is no pricking and scratching hands situation.

 

When purchasing hollow pipe handles, we should pay attention to the fact that the thick pipe of handles should sound crisp while thin pipes are deep when tapping them gently with a hard object.

 

The center of the door is cylinder. Generally, there will be 0 degree or 30 degree offset cam inhibits knock through. It needs the key and turn to the degree to open the lock. This cylinder will not come out of the lock body even without fixing the screw, so it has high safety. The more number of cylinder pins, the stronger the anti-opening performance and safer.

Poor quality cylinders are easy to be inserted by key and difficult to pull out. So when choosing cylinders, we must verify whether the key is difficult to pull out.
