Wanbaoyijia Cheap Interior Door Structure and Cost Configuration
Our Cheap Interior Doors use a hollow internal structure. A solid timber frame forms the basic structure of the door leaf, with a frame width of 30 mm. Depending on your project budget, the door leaf can use honeycomb paper or spaced particleboard as the filling material, allowing you to choose a more suitable configuration based on basic usage requirements and purchasing cost.
The door frame uses a solid structure with a thickness of 30 mm, and the door frame facing is 4 mm thick. Even if your project has a limited budget, you can still obtain a complete door set with a solid door frame, rather than reducing all structural materials simply to lower the price.
Taking our factory standard size of 2100 × 900 × 160 mm as an example, a complete Cheap Interior Door set weighs approximately 25–30 kg. The lighter door set also makes handling and on-site installation more convenient for large-volume projects.
Popular Cheap Interior Door Designs
Cheap Interior Doors are available with PVC or melamine finishes, together with practical colours and simple panel designs. The following are some commonly selected styles for budget-conscious residential projects and large-volume interior projects.

A plain grey surface with a slim black curved line adds a simple decorative detail while keeping the overall door design clean and economical.

Grey wood grain with narrow gold-coloured strips creates a more decorative appearance while maintaining a simple and practical door design.

A light grey flush surface with a curved dark line provides a clean modern look for apartments and other residential interiors.

A white flush door with a black horizontal line and simple geometric detail adds visual interest without using complex panel mouldings.

A simple wood-grain surface combined with electronic lock hardware is suitable for apartment and residential projects requiring smart-lock installation.

A plain grey door leaf with matching frame and black hardware provides a clean, practical option for large-volume interior projects.

The light vertical wood grain and simple flush surface provide an easy-to-match design for apartments, offices, classrooms and other projects.

An asymmetric vertical line adds a modern decorative detail to the grey flush surface without making the overall design overly complicated.

Light wood grain combined with a narrow black strip creates a simple contrast and gives the door a more modern appearance.

Two narrow vertical decorative lines add a subtle design detail to the light grey surface while maintaining a minimalist overall appearance.

A brown wood-grain surface with simple horizontal and vertical lines creates visual sections without requiring traditional raised panel construction.

A narrow decorative line with a small shaped detail gives the brown wood-grain surface slightly more character while retaining a simple design.
Cheap Interior Doors by Core Configuration
Cheap Interior Doors can use different internal structures to suit different purchasing budgets.
Honeycomb Paper CoreThe door leaf uses a solid timber frame with honeycomb paper filling inside. This configuration uses less filling material and is more suitable for large-volume projects with a low budget.
Eucalyptus Frame + Particleboard FillingThe door leaf uses a eucalyptus frame with spaced particleboard filling. Compared with honeycomb paper, this configuration uses more solid material inside the door leaf while remaining suitable for projects that need to control overall purchasing costs.
Rubberwood Frame + Particleboard FillingThe door leaf uses a rubberwood frame with spaced particleboard filling. Rubberwood is harder than eucalyptus, so the frame has stronger resistance to deformation.
Advantages of Cheap Interior Doors
Cheap Interior Doors are mainly positioned for controlling purchasing costs, while still offering several options for adjusting the product configuration.

You can upgrade from honeycomb paper to particleboard filling, or upgrade the internal frame from eucalyptus to rubberwood. Even within a lower price range, you still have several material grades to choose from to suit different project requirements.

The standard door leaf thickness is 50 mm. Compared with 45 mm door leaves in the same price range from other factories, the 50 mm door leaf provides better sound insulation, giving you better value for money.

The standard configuration can use three 2.5 mm thick hinges and an aluminium-alloy split lock. For ordinary budget projects that do not require heavy door leaves, this hardware combination is sufficient for daily use.

The door leaf uses a 4 mm MDF facing panel and can be finished with PVC or melamine. The 4 mm facing panel helps maintain the flatness of the door leaf.

Depending on your budget, the architrave can be made from WPC or multi-layer plywood. More material options can help you reduce your overall project cost.

The door frame uses a foam sealing strip, which provides better sound insulation than a rubber sealing strip and also gives the door a more substantial closing sound. Even for economical projects, it can provide good sound insulation.
Door Leaf Packaging
To protect the areas that are more likely to be knocked during transport, our door leaves are wrapped externally with cardboard, with protective foam added around all four edges. The door leaf is then placed in a plastic bag, with plastic corner protectors fitted to all four corners.
For large-volume residential, apartment and other budget-oriented projects, this packaging method avoids adding excessive purchasing cost for the packaging itself while still providing the basic protection required during transport.


Solid Door Frame Structure
Although Cheap Interior Doors use a lower-cost internal door leaf configuration, the door frame does not use a hollow structure. Our standard configuration uses a solid door frame with a thickness of 30 mm, with eucalyptus used as the door frame substrate.
To reduce the risk of door frame deformation, we add an additional backing board to the bottom of the door frame so that the stresses on the front and back are better balanced. This can help reduce your after-sales costs.

Automated Production Line Improves Batch Production Efficiency


To complete batch production of Cheap Interior Doors faster and more consistently, we use an automated edge-banding and hardware-hole machining production line.
With traditional production methods, workers usually need to lift the door leaf onto the edge-banding machine and manually turn it after each edge is finished. All four edges require repeated handling and adjustment. After edge banding, the door leaves also need to be stacked and then moved by workers to the lock-hole machining area for the next process.
Our production line is better suited to the batch production of Cheap Interior Doors. After edge banding is completed, the door leaf can be transferred directly by conveyor to the hardware-hole machining process, reducing intermediate stacking and manual handling.
For your batch orders, this production method can reduce the risk of scratches and knocks during door leaf handling while improving the efficiency between production processes, usually helping us shorten the production lead time by approximately 1–2 days.
Cheap Interior Door Solutions for Cost-Controlled Projects
Different Cheap Interior Door projects may have different requirements for core filling, door frame structure, architraves and hardware while keeping the overall budget under control. The following cases show how we adjusted the door configuration according to different project budgets and usage requirements.

In a project in Nigeria, the customer needed 200 door sets for a hotel. He did not want honeycomb paper filling because he felt that the structure was too hollow, and he also did not want particleboard filling because he felt that particleboard was not hard enough. After further discussion with the customer, we decided to recommend plywood filling. Plywood is harder than particleboard and costs slightly more. After watching the video we sent, the customer decided to use plywood filling. The project has now successfully passed acceptance.

In a project in Egypt, the customer wanted to use a hollow door frame structure for the Cheap Interior Doors to reduce the budget. After reviewing the design provided by the customer, we still recommended a solid door frame structure because the door leaves were relatively large, reaching 1.1 metres in width. A hollow door frame would not provide enough support for such a large door leaf, and if problems occurred later, the after-sales cost would be higher. The customer ultimately accepted our recommendation.

In a project in Tanzania, the customer’s project was for temporary buildings with an estimated service life of 2–3 years, so the customer wanted to use wooden doors at the lowest possible cost. After further discussion, we recommended WPC architraves. Using WPC architraves could reduce the budget for the complete door set by 5%–8%. The customer recalculated the project cost and ultimately chose WPC for the architraves.

In a project in Libya, the customer’s project was a budget hotel, so the customer wanted to reduce costs as much as possible. After reviewing their design, in addition to particleboard filling and WPC architraves, we also recommended using a knob lock. A knob lock has a simple mechanical structure, good stability and a low price, and it is also easy to repair after installation. After watching the sample video we provided, the customer ultimately accepted our recommendation.

Customer Feedback on Wanbaoyijia Cheap Interior Doors
Yes. If different rooms have different budget or usage requirements, the same project can use different confirmed core configurations, such as honeycomb paper, spaced particleboard or plywood. Each configuration should be clearly marked in the Door Schedule before production.
It depends on the actual usage environment. A standard Cheap Interior Door is mainly intended for normal indoor environments. If the wooden door needs to be installed in an area with relatively high humidity or frequent moisture exposure, the facing material, edge sealing, door frame and core configuration should be reconfirmed before ordering.
This should not be assumed. The Cheap Interior Doors described on this page are standard interior doors, and no fire rating is claimed. If your project requires a certified fire-rated door, the fire-rating requirement should be confirmed as a separate door system.
No. The 2100 × 900 × 160 mm shown on this page is only a reference door-set size. For an actual project, the door opening dimensions and wall thickness should be provided so that the final door leaf and door frame dimensions can be confirmed.
We do not recommend reducing every part of the wooden door to the lowest specification at the same time. First confirm where the door will be installed and which basic requirements must be retained, then control the cost through the core, architrave, finish and hardware configurations.
If the project is budget-sensitive and the wooden door configuration matches the actual application, a Cheap Interior Door can be a reasonable choice. However, it should not be expected to have exactly the same weight, internal structure or other performance as a higher-spec solid door. When purchasing, the specific specification should be compared rather than only the price.
In most cases, it is a hollow-core door because a solid door requires a higher budget.
Generally, it cannot be trimmed on site because the door leaf or door frame of a Cheap Interior Door has PVC edge sealing. Trimming it on site would affect the appearance, and moisture could later enter the door, shortening its service life.
Yes. Cheap Interior Doors can be used in budget-sensitive apartments, hotels and residential bedrooms.
Yes. If the project requires it, a glass design can be considered for a Cheap Interior Door.
