Overview of Common Materials
The majority of premium balance boards are constructed from solid hardwoods or birch plywood.
Durability, load capacity, weight, and surface finish quality are all directly impacted by the material.
Birch Plywood – The Industry Standard
Why most factories use birch plywood
1)High strength-to-weight ratio
2)Stable structure; not easy to crack or warp
3)Flexible enough to withstand bending force
4)Consistent quality for mass production
Typical specifications:
11–13 layers for standard boards
Thickness: 15–18mm
Load capacity: 100–150kg
Solid Wood Options
Common choices: Beech / Rubberwood / Pine
Solid wood boards are more "premium," but much harder to control in:
1)Moisture content
2)Warping
3)Color consistency
Plywood Structure & Thickness Guide
More layers = stronger, more stable
Layers define the board's bending strength.
Practical guidance:
1)9 layers → light training only / cheaper models
2)11–13 layers → mainstream balance boards
3)15 layers → heavy-duty or extra-wide boards
Thickness impact:
1)15mm: standard, flexible
2)18mm: stronger, heavier
Material Choice & Load Capacity
Birch plywood:
1)100–150kg depending on thickness
2)Best for families & kindergarten usage
Solid wood:
1)80–120kg (varies by wood type)
2)Easier to dent or scratch
Low-quality plywood:
1)Lower density, unstable glue layers
2)Board may crack under repeated bending
Material & Load Performance
A practical and stable configuration for balance boards is 11–13 layers of birch plywood with 15–18mm thickness.
This structure provides strong load capacity while keeping enough flexibility for smooth rocking.
It also reduces the risk of cracking or warping during long-term use.
Using E0/E1 grade adhesive helps maintain low formaldehyde levels and supports common safety requirements.
For wider or heavier-use models, thicker boards or additional layers can further enhance durability.
