1 . Key Points for Door Frames and Door Panels - Door Frame Material and Door Panel Thickness

At present, the sliding door materials used in the market are carbon steel materials, aluminum-titanium alloy materials, etc. Among them, aluminum-titanium alloy materials are the most durable; secondly, the thickness of the door panel, and the planks used for sliding doors, are preferably 10 mm or 12 mm thick. , It is only stable and durable when used. When the thickness is less than 8mm, it will appear thin and light. The door with thickness less than 6mm is easily deformed and it is difficult to meet the requirements of normal use.

2 . Key Aspects of Wheels - Bottom Wheel Load Capacity and Flexibility

The pulley is the most important hardware component in sliding. At present, there are three types of pulleys on the market: plastic pulleys, metal pulleys, and glass fiber pulleys. Plastic pulleys have a hard texture, but they are easily broken. They can become astringent and hard when used for a long time. The push-pull sensation becomes very poor. The strength of the metal pulleys is large, but they are prone to noise when they contact the rails. The toughness and resistance of the glass fiber pulleys Grinding, smooth sliding, durable.

3 . Track key point - track positioning and damping device

The high-quality sliding door hardware is mainly reflected in the design and manufacture of the pulley system and the track, and the perfect combination of the two. The track is crucial. The quality of the rails depends on the curvature of the rails that must be matched with the pulleys. It should be reminded that good rails are superior in strength design and the smoothness of the contact surface with the pulleys. The thicker the rails, the better. At present, there are two kinds of cold-rolled steel rails and aluminum alloy rails. Rails are not always good. It should be said that good aluminum alloy rails are superior to rails in some respects, especially in terms of noise immunity. The
Also pay attention to whether the product has a stop block and an upper and lower rail positioning system, whether there is a glass bumper tape, whether the bearing pulley is smooth and silent when pushing, whether a damping system is placed in the bottom wheel, whether there is a door height adjustment device, etc. .

4 . The key point of sealability - the door interval does not exceed 5 mm

In order to ensure that the two doors are staggered and closed, all the sliding door products will be spaced. Generally, the outer pulley needs a 15 mm interval. This interval affects the sealing performance of the sliding door. In particular, Beijing has large wind and sand, and there are many opportunities for dust intrusion.
Although most products have wool tops, the size of the tops used in different products is still relatively large. Try to choose products with small intervals and tops. For example, the distance between the sliding doors of German aunts is only 5 mm. With the high-density tops, dust intrusion is basically eliminated.

5 . The key to the service life - brand credibility

The key factor affecting the life of the sliding door is the pulley. The design life of the big brands of pulleys is all about 15 years, and some pulleys of counterfeit products may be broken in 2-3 months, which seriously affects the use of sliding doors.
