A premium wheelchair not only moves beautifully but also looks beautiful.
At Brother Medical, every curve and contour is intentional, designed to capture the elegance of motion while meeting the highest engineering standards.
Refined geometry and streamlined tubing give each model a sleek, confident stance — balancing structure and style.
Every angle and joint flows naturally, creating a visually lighter yet stable and stronger outline.
Behind every beautiful frame lies a material built to perform.
We use 7000-series aviation-grade aluminum alloys instead of conventional 6000-series.
Property | 6061 Alloy (Standard) | 7003 Alloy (Brother Medical) | Advantage |
Yield Strength | 270 MPa | 400 MPa (+48%) | Stronger & stiffer |
Density | 2.70 g/cm³ | 2.68 g/cm³ | Slightly lighter |
Surface Finish | Brushed | Deep anodized gloss | More refined |
Fatigue Resistance | Moderate | Excellent | Longer lifespan |
The difference is immediate — a deeper metallic luster, lighter structure, and superior fatigue resistance. 7003-series frame not only enhances performance but elevates the aesthetic — delivering a subtle, high-end metallic finish that appeals to discerning users in Japan, Europe, and North America.
Inspired by advanced models from Permobil and other global leaders, our engineers integrate oval-tube geometry into the frame and cross-brace design.
Higher rigidity: Up to 20 % stronger than round tubes under the same load.
Reduced weight: Thinner wall sections cut frame mass by ≈ 1.2 kg.
Enhanced aesthetics: Smooth, elliptical contours create a visually refined silhouette.
Each cross-brace uses an internal reinforcement layer that strengthens high-stress zones without adding unnecessary weight — delivering the perfect balance of agility and stability.
Many wheelchairs failures stem from overlooked details, such as cracked footrests, loose arm clamps, or poor material choices made by cost-cutting suppliers. Our engineering team provides targeted reinforcement solutions, such as rib-strengthened footplates and upgraded alloy joints, ensuring reliability without added bulk.
Before: Common aluminum footrests breaking under pressure.
After: Reinforced rib design → +42 % strength, extended lifespan, zero customer returns.
Every component we deliver is fully traceable, tested, and verified to meet your exact specifications — ensuring 100 % compliance and consistent quality across batches.
In the world of mobility, beauty and precision are no longer separate.
Through material science, ergonomic design, and aesthetic mastery, Brother Medical turns wheelchairs into expressions of aesthetics; every ride becomes a statement of balance, strength, and grace.
