Medium Duty MDF Hardboard Door — 900mm × 2032mm
This Medium Duty MDF Hardboard Door is one of the most widely specified interior doors in South African residential and commercial construction. At 900mm wide, it meets the minimum clear opening requirement for wheelchair-accessible doorways under South Africa’s National Building Regulations, making it a standard choice for accessible bathrooms, en-suites, and passage doorways in inclusive builds.
Constructed with an internal pine framework and a plain MDF skin on both faces, this door offers greater strength and impact resistance than traditional Masonite-skinned doors, while remaining lightweight enough for easy handling and installation.
Key Features
-
Plain MDF skin (both sides) – Stronger and more durable than traditional Masonite skins; smooth surface for an even paint finish
-
Internal pine framework – Structural timber frame provides rigidity and solid fixing points for hinges, locks, and closers
-
Exposed wooden edges – Standard medium-duty construction; seal edges before painting to prevent moisture absorption
-
900mm width – Meets the minimum accessible doorway width under SANS 10400-S and is widely used for wheelchair-accessible rooms
-
40mm thickness – Compatible with standard interior door frames and hardware
-
Paintable – Prime and paint in any colour; MDF skin accepts water-based and enamel paints evenly

Why the 900mm Width Matters
Under SANS 10400-S (Facilities for Persons with Disabilities), a minimum clear opening width of 850mm is required for accessible doorways, with 900mm being the widely adopted standard in South African construction. A 900mm door leaf installed in a correctly sized frame provides the full clear opening needed for standard wheelchairs, mobility aids, and assistive devices. This makes the 900 × 2032mm door the default specification for accessible bathrooms, en-suites, and any doorway on an accessible route in both residential and commercial buildings.
MDF Skin vs Traditional Masonite — What’s the Difference?
Traditional Masonite (hardboard) skins are thin and relatively brittle, making them susceptible to dents and surface damage. MDF skins are denser, more uniform, and significantly more impact-resistant, resulting in a door that holds up better in high-traffic environments and maintains a smoother surface over time. MDF also accepts paint more evenly, reducing the number of coats needed for a quality finish.
Ideal Applications
- Wheelchair-accessible bathrooms and en-suites
- Accessible doorways on compliant routes in residential and commercial buildings
- Bedrooms, passages, and living areas requiring a wider door opening
- Rental properties, retirement villages, and care facilities
- Medium-traffic interior doorways in offices and commercial spaces
Finishing Tips
Seal all edges — including the top, bottom, and exposed side edges — with a dedicated MDF primer or edge sealer before painting. Apply two coats of acrylic or enamel paint for a durable, washable finish. Do not use oil-based stains as MDF has no wood grain and will not absorb them evenly.
