What types of sliding doors are there? Selection and maintenance of sliding doors


A sliding door refers to a door whose door leaf is connected to a pulley and moves on a fixed track, also known as a sliding door. It is different from the side hinged door which connects the door leaf with hinges. Sliding doors have the characteristics of easy installation, reusability, industrial production, and small workshop production, fire prevention, and environmental protection.

Sliding doors bring great convenience to people's work. For example, you can move it aside when you need it, so that the two spaces are temporarily combined to appear larger. For another example, the general company's factory buildings may be rented, and we will inevitably have to change places due to various reasons. At this time, the disadvantages of traditional partitions are easily revealed, because you can't take away the components that belong to the house. On the contrary, the sliding door is detachable, removable, and reorganizable, so the sliding door has the reputation of being a decoration that can be taken away.

The role of sliding doors

1. Separate space

Sliding doors have the function of partition, so if you want to divide an exclusive space, sliding doors are the first choice.

2. Block the line of sight

The transparency of the material is different, and it has the effect of blocking the line of sight to a certain extent.

3. Appropriate sound insulation

Good quality insulating glass has better sound insulation effect.

4. Enhance privacy

If you don't want others to see a certain place, then sliding doors are a very good choice.

5. Increase space flexibility

Sliding doors can be activated or moved at any time according to the use requirements, structural form, and decoration style, and the space will be divided or closed, enlarged or reduced accordingly, and more flexible and changeable according to subjective wishes.

6. Replace the casement door

Swing doors require much more space than sliding doors, and the installation cost is also higher. The sliding door is not only easy to install, but also can be disassembled and taken away, which is very convenient!

Classification of sliding doors

1. Divided by installation location

Generally divided into: partition door, closet door. The partition doors include: kitchen partition, living room partition, balcony partition and bathroom partition. Closet doors include: integral wardrobes and walk-in wardrobes.

2. Divided by style

There are many kinds according to the style, among which the partition door includes: white glass, embossing, car engraving, silk screen, jade sand, rattan, silk, etc.; the closet door includes: baking varnish, louver, plate, porcelain, leather , soft bag, etc.

3. Divided by main raw materials

The main raw materials are door frame, door leaf and track can also be sorted. Commonly used are the following categories:

1. Solid wood sliding door.

2. Log sliding door.

3. Glass sliding door.

4. Stainless steel sliding door.

5. Steel wood sliding door.

6. Aluminum alloy sliding door.

7. New composite material sliding doors, such as wood-plastic wave board sliding doors.

Four, divided by sliding track

According to the position, it can be divided into upward sliding (also known as hanging rail or hanging sliding), sliding or ground rail; according to the number of tracks, it can be divided into single-track sliding door and double-track sliding door.

How to choose a sliding door

1. Frame profile

The base materials generally include aluminum alloy and plastic steel. Because aluminum alloy has the characteristics of light weight and high strength, it is a high-grade material for the base material of sliding doors, and has gradually replaced plastic steel products. Aluminum alloys are divided into ordinary aluminum-magnesium alloys and aluminum-titanium-magnesium alloys. Titanium metal has the characteristics of high strength, small specific gravity, and high toughness. Therefore, its price will be several times more expensive. In addition, advanced surface treatment includes anodic oxidation, electrophoretic coated carbon spraying and other processes, which have higher hardness and aesthetics than simple spraying and electroplating.

2. Door panel material

Density board: It has weight, has a feel, and is cheap. Poor quality boards will be deformed. Good density boards will have the company's stamp on the back.

Glass: There are patterns on the surface, which have the characteristics of light transmission and opacity; Engraved glass: The patterns drawn generally have individual "creativity"; Stained glass: The painting film has strong adhesion and can be scrubbed.

There are also materials such as metal and aluminum alloy. From the decoration point of view, wood is closer to nature, and metal and organic materials are modern.

It should also be selected according to the location of use, such as wardrobe sliding doors are generally made of wood, and balcony sliding doors are generally made of tempered glass.

3. Board style

Partition: As a partition door, most of them are relatively transparent panels, which can make the space more open, take into account the decorative effect, and match the overall room style.

Cabinet door: The materials include wood, glass, mirror and others. The height of the glass sliding door should not exceed 2.5 meters. The bedroom should not choose a mirror sliding door. The panel sliding door is simple and elegant, and has good safety. In addition, there are also louver series sliding doors and panel sliding doors.

4. Pulley slide rail

Shake the sliding door in the vertical direction of the slide rail, the smaller the shaking, the better its stability. When shaking, pay attention to observe the upper pulley and the upper slide rail. If the sliding door is of good quality, the gap between them is almost zero. In this way, there will be no vibration when sliding, and it will be smooth and smooth. Therefore, the tight combination of the upper pulley and the slide rail determines the smoothness of its sliding.

5. Sealing effect

It is advisable to choose a built-in bearing bottom wheel with a large load-bearing capacity. This kind of bottom wheel has high technological content and can cope with various conditions of the ground. In addition, the quality of the sealing brush is also very important, it is attached to the back of the door. A good-quality sealing brush adhesive has a high viscosity, and there is no fading of the brush bristles. When it is closed, the door and the door will be tightly bonded, so there is no need to worry about dust intrusion.

6. Stop device

The stop block is generally made of steel sheets, but the durability of the steel is stronger, and the steel is not good, and it will shift after a long time of collision, so that the sliding door cannot stop in place. In fact, metal has a fatigue period, and it is easy to deform after a long time of work, while the stop block made of copper is resistant to corrosion and can remain stable for a long time, so you can choose such a material as much as possible.

7. Sliding effect

It is wrong to think that the lighter the sliding door is, the better. In fact, this view is wrong. A high-quality sliding door should be neither too light nor too heavy when sliding, but with a certain weight of the door. There is no vibration at the time, smooth and textured. Although some sliding doors are relatively light to push and pull, they will have the feeling of "floating" and are not stable enough. To carefully experience the feeling of sliding.

8. Is there any noise

Generally, the factors that cause sliding noise are the poor workmanship of the bearing pulley and the gap between the pulley and the track. Although some bottom wheels slide smoothly at that time, if you observe carefully, you will find that there is a greasy feeling on the bottom wheel. This is because some sellers have oiled the bottom wheel in order to achieve the purpose of sliding and mute. In this way, it is not only easy to be contaminated with dirt, but once the grease dries, it will be blocked and cause noise.

9. Advantages and disadvantages of the bottom wheel

Only the bottom wheel with super large load-bearing capacity can guarantee its good sliding effect and long service life. High-grade sliding doors are made of carbon fiberglass, with balls inside and non-drying lubricants. Poor pulleys are often made of engineering plastics or organic plastics, with small load-bearing capacity. It may not be a big problem when you start using them. It is easy to deform after a long time, which will affect the push-pull effect.

10. Gadgets

When selecting, pay attention to the settings of other small accessories of the sliding door: such as anti-jump devices, shock absorbers, height adjustment systems, dust-proof brushes, rubber strips at the junction of glass and metal frames, etc.
