- The door slides along the wall without taking up swing space
- No full-length exposed floor track, making the floor easier to clean
- Soft-close hardware reduces impact and noise at both ends
- The door leaf stays close to the wall for a simpler appearance
- Matching wall panels are available for door-and-wall integration.
How Wanbaoyijia Concealed Sliding Doors Are Constructed
Concealed sliding door leaves are usually larger than standard hinged door leaves. We reinforce all four sides of the door leaf and use about twice as much perimeter-frame material as a standard door leaf.
To keep the door weight within the hardware load limit, we normally use 4 mm face panels. The internal core layout is adjusted to reduce unnecessary weight while keeping enough support around the edges and hardware areas.
For larger doors or projects with special requirements, aluminium honeycomb can be used as the door core. It reduces the door weight while providing support across the door leaf.
You can send us the door size, finish and hardware requirements, and we will recommend a suitable door leaf structure.
Concealed Sliding Door Options by Finish and Door Leaf Material
You can select the door leaf finish according to the required appearance and project budget. The internal structure can also be adjusted according to the load capacity of the concealed sliding hardware.

The door leaf is finished with melamine panels in solid colours or wood grains. You can keep the appearance consistent across apartments, hotels and other batch projects at a lower cost.

The door leaf is sanded and painted. It can have a flat surface or simple CNC-routed designs. You can select the colour and gloss level according to your project design.

Natural or engineered wood veneer is pressed onto the door leaf and then finished with paint or a clear coating. You can achieve a wood-grain appearance while keeping the concealed sliding structure.

PET film is laminated onto the flat door panel and is available in various solid colours. You can use it to match modern interiors.

PVC film is laminated onto the flat door panel and is available in different colours and textures. You can select a suitable finish according to your budget and interior style.

Aluminium profiles are fitted around the edges of the door leaf. They help protect the door edges from moisture and impact. You can use this option in frequently used or moisture-prone areas.
Concealed Sliding Door Details Confirmed Before Production
Before production, Wanbaoyijia checks the door size, hardware system, sliding direction and site conditions with you. This helps reduce machining errors and makes the doors easier to identify and install at the project site.

We check the selected hardware and confirm the upper and lower groove positions before CNC machining, helping you reduce fitting problems at the project site.

We calculate the door leaf width and height according to the opening and selected hardware system, helping you avoid insufficient overlap or an incomplete opening.

We confirm whether each door slides to the left or right, helping you avoid opening-direction errors during installation.

You can provide the site dimensions so we can check whether there is enough side wall space and top clearance for the door to move and the hardware to be installed.

We check the estimated door leaf weight against the hardware load capacity, helping you avoid using an undersized sliding system.

You can confirm the colour, texture and gloss level before production, helping keep the finished doors consistent with the approved sample.

For batch orders, we can test the first door leaf with the selected track, rollers and other hardware, helping you identify mismatches before mass production.

We can mark the door number, sliding direction and hardware package number, helping your installation team match each door with the correct hardware.
More Options for Your Concealed Sliding Door Order
Wanbaoyijia provides different hardware, opening and packing options, allowing you to select a suitable configuration for your project and installation method.

The hardware position can be adjusted for full or partial opening, depending on the door opening size and the available wall space.

You can send your selected hardware to our factory for machining, or purchase the door together with our matching concealed sliding hardware.

The track, rollers and other parts can be pre-installed for testing or packed separately according to your shipping and installation requirements.

Recessed pulls, edge pulls, magnetic catches and selected privacy locks are available, depending on the door structure and application.

You can order decorative panels together with the door leaves, helping you keep the door and wall finishes consistent.

The hardware is packed separately from the door leaf with labels and protective materials, reducing the risk of missing parts or transport damage.
Reinforced Upper and Lower Groove Areas
Concealed sliding doors normally require a hidden track groove at the top of the door leaf and a guide rail or roller groove at the bottom. These grooves remove part of the original door structure, so additional support is needed in these areas.
Before routing, Wanbaoyijia adds more solid wood blocks to the top and bottom of the door leaf, using about twice the amount used in a standard door leaf. The tracks, screws and roller components are fixed into these reinforced areas instead of only into the thin face panels.
This structure helps reduce the risk of cracking, loose hardware, sagging and door leaf deformation during long-term use.


Factory CNC Routing Based on the Sliding Hardware
Some concealed sliding door leaves are routed on site by installers. Wanbaoyijia can complete this machining in the factory before delivery.
You can send us the selected hardware, installation template or technical drawings, or use the concealed sliding hardware supplied by our factory. Before CNC programming, we check the dimensions of the upper track, lower track, rollers and other components.
The factory machines the upper and lower grooves according to the actual hardware, keeping the groove dimensions between 0 and 2 mm larger than the corresponding hardware dimensions. We can also carry out a fitting test before packing to reduce groove-position errors, hardware mismatches and on-site rework. At the project site, the installers mainly need to fix the wall brackets, hang the door and complete the final adjustments, making installation easier.
Helping You Prepare for a Concealed Sliding Door Order

Use this checklist to record the door opening width and height, wall type, available side wall space, top clearance, finished floor level, and any switches, sockets or skirting boards near the door opening.

Use this sheet to record the hardware brand, model, load capacity, track dimensions, roller positions and required groove dimensions, so the factory can check them before machining.

Concealed Sliding Doors for Complete Projects


Wanbaoyijia manages more than 20 interior door factories. You can purchase concealed sliding doors together with the other door types required for your apartment, hotel or commercial project.
We can coordinate the colours, finishes, door leaf heights, edge details, packaging and delivery batches for the complete order. You do not need to purchase a small quantity of concealed sliding doors from one supplier and then find other suppliers for the remaining project doors. We provide a one-stop concealed sliding door solution.
Concealed Sliding Door Solutions for Different Project Conditions
The following cases show how Wanbaoyijia provided different solutions based on each project’s requirements.

For an apartment project in Hong Kong, the available wall space beside the concealed sliding door opening was limited. We checked the door opening size and the distance between the opening and the side wall. We then recommended reducing the door leaf width by 5 cm, which solved the problem of the door being unable to open fully. The concealed sliding door has now been installed, and the client is satisfied with the result.

For a project in Thailand, the client ordered 20 sets of concealed sliding doors. As the client did not have suitable cutting equipment at the project site, they sent the hardware and installation drawings to our factory.
We checked the dimensions of the upper track, lower track and rollers against the door leaf dimensions, and then used CNC equipment to machine the required grooves. After receiving the doors, the client completed the installation with simple fixing work. This reduced on-site machining and shortened the installation time.

For a project in Malaysia, the concealed sliding door leaves were 2.7 metres high and 1.2 metres wide. Because of the large size, the project manager was concerned about the load capacity of the hardware.
We recommended aluminium honeycomb or acoustic foam filling to reduce the weight of the door leaves. The client accepted our recommendation.

For a kitchen project in China, the project manager wanted to install concealed sliding doors but was concerned that the humid kitchen environment could reduce the service life of wooden doors.
We recommended aluminium-edged door leaves with water-resistant decorative panels. The aluminium profiles protect the door edges, and the system does not require a full-length exposed floor track, helping reduce dust around the doorway.

Client Reviews of Wanbaoyijia Concealed Sliding Doors
No. A concealed sliding door moves along the outside of the wall, with the main track and running hardware hidden behind or inside the door leaf. When a pocket door is opened, the door leaf slides into a cavity inside the wall.
A standard wall-mounted sliding door also moves along the wall, but the track and rollers are usually visible. These three door types have similar opening movements, but they use different hardware and wall structures.
Not necessarily. On this page, “concealed” mainly means that the track, rollers and other running hardware cannot be seen from the front.
The door leaf still moves along the outside of the wall, so an operating gap is required between the door leaf and the wall.
It depends on the door leaf structure and the selected hardware. Recessed pulls, edge pulls, magnetic catches and some privacy locks can be used, but the installation positions must be confirmed before production.
A concealed sliding door normally does not use the same lock and sealing structure as a hinged entrance door. It is more suitable for interior partitions and is not recommended as an entrance door where higher security is required.
A standard concealed sliding door is generally less airtight and provides less sound insulation than a hinged door. Operating gaps are required around the door leaf to prevent it from rubbing against the wall or floor while sliding.
It can be used in these areas, but the actual project requirements should be considered first. If a bedroom requires better sound insulation and privacy, a standard hinged door may be more suitable.
For bathrooms, concealed sliding doors are more suitable for dry areas. The door leaf should use moisture-resistant materials or aluminium edging, and water should not enter the bottom grooves or hardware directly. Kitchens, wardrobes, living rooms and interior partitions are usually more suitable applications.
No. Concealed sliding door leaves normally require additional reinforcement around all four sides, while most standard door leaves do not have this reinforcement.
In addition, a concealed sliding door leaf is usually much larger than the door opening, while a standard door leaf is normally smaller than the opening.
A correctly installed system normally requires only basic maintenance. Use a dry cloth regularly to clean the roller paths, bottom guide and accessible track areas.
Do not spray liquid cleaner directly onto the rollers, dampers or tracks.
A complete concealed sliding door hardware set normally includes a door-mounted upper track, wall-mounted roller brackets, soft-close devices, side guide rollers, bottom rollers or a lower guide rail, a floor guide, travel stops, an anti-jump device and installation accessories.
The hardware should be selected according to the door leaf weight, thickness, width, height and required opening distance.
The rated load of the hardware should be higher than the actual door weight. The track dimensions and roller positions must also match the grooves in the door leaf.
Yes. Concealed sliding doors can be fitted with single-end or double-end soft-close devices.
A double-end soft-close system slows the door leaf near both the fully open and fully closed positions, reducing impact and noise. The damper position and soft-close travel must be confirmed before the door leaf is machined because they affect the track layout and opening distance.
