Type of sliding door
The sliding door is actually not a new object, but due to process problems, the quality of the pulley and the slide rail is not reliable, and problems such as deformation of the door panel, sluggish push and pull, and severe noise have appeared from time to time, which has greatly damaged people's enthusiasm for using the sliding door.
Today, sliding doors have entered the stage of specialized production, and the improvement of product quality has also led to the popularity of sliding doors.
In the sliding door, the straight-rail sliding door is the most widely used, it can be applied to various areas, the track form is divided into single track, dual track and three tracks. In addition, the impact angle sliding door is suitable for the corner area and is divided into two types: external impact and internal impact, and the angle of impact is 90 degrees and 135 degrees.
Angled sliding doors are suitable for the top floor of villas and duplex houses. Folding doors are mainly designed for smaller spaces and can exhibit 100% of the space for taking things. Swing door is a kind of product extended on the basis of sliding door. It does not need slide rails, but uses the shaft as the switch. The form is unique.
The wall frame door is an important part of the sliding door. There are a variety of oak wood sliding doors, color panel sliding doors, stylish metal sliding doors, exposed frame glass sliding doors and many other.
First, door frames and door panels
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 wood used for sliding the doors, are preferably 10mm or 12mm thick. Plates are only stable and durable when used. When the thickness is less than 8mm, they will appear thin and light. The doors with thickness less than 6mm are easily deformed and it is difficult to meet the requirements for normal use.
Second, pulley
Whether or not the sliding door can be used for a long time depends on the quality of the pulley. Sliding doors usually have a height of more than 2.4 meters. The doors are wider and their weight is greater. If the bearing weight of the bottom wheel is not enough, it will greatly affect the service life. Currently, there are three types of pulleys on the market: plastic pulleys, metal pulleys, and fiberglass 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.
Third, orbit
The charm of the sliding door is sliding and sliding. Therefore, the hardware of the sliding door is very important. This is mainly reflected in the design and manufacture of the pulley system and the track. What is more important is the perfect combination of the two. A good track is better in strength design and smoothness to the contact surface of the pulley. At present, there are two kinds of cold-rolled steel rails and aluminum alloy rails.
Fourth, sealing
In order to ensure that the two doors are staggered and closed, all sliding door products will have a gap. Generally, an external pulley needs a 15 mm interval. This interval affects the sealing of the sliding door. 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.
Fifth, sliding effect
The quality is good or bad, speaking without a certificate, on-site inspection is very important. A good sliding door is neither too fluttering nor too heavy when sliding, but with a certain weight of the door, no vibration when sliding, smooth and texture.
