When it comes to staircase construction, accuracy matters. Each tread, riser and stringer must fit perfectly to deliver both safety and style. That is why so many builders and fabricators trust CUSTOMwood Raw MDF. Engineered to meet Australian standards, it offers exceptional consistency, durability and finish quality, making it one of the most reliable materials for stair manufacturing.
Why MDF Works for Staircases
Medium Density Fibreboard, or MDF, is a foundation in joinery because of its uniform structure, smooth surface and predictable performance. For staircases, these features translate into:
- Consistent thickness across every sheet
- Smooth, defect-free surfaces without knots or irregular grain
- Clean machining for precise profiles, rebates and housings
- Minimal risk of cupping, splitting or warping over time
CUSTOMwood Raw MDF adds another layer of assurance; it is purpose-built for repeatable results, whether you are cutting on-site or manufacturing in volume.
Stair Components Made Simple
Treads: MDF offers a flat, stable base that feels solid underfoot and machines easily for nosing details or anti-slip profiles. Its smooth surface accepts decorative finishes such as laminates, vinyl or carpet.
Risers: Dimensional stability and a paint-ready surface make risers quick to cut, easy to finish and secure once installed.
Stringers: The backbone of a staircase demands strength and precision. MDF’s stable core ensures tight joints and lasting performance, with sheet sizes available for both open and closed designs.
