MATSUNAGA Wheelchair Frame: Strong and Lightweight with Grade 7 Aluminum Alloy

MATSUNAGA wheelchairs are designed and manufactured with meticulous care to deliver the best possible experience for users in terms of strength, safety, and comfort.

One of the key elements of MATSUNAGA’s quality lies in the main structure of the wheelchair, which is made from Grade 7 aluminum alloy—a high-performance material (with Grade 8 being the highest level). This material is not produced in Thailand and must be imported from overseas.

Key Features of Grade 7 Aluminum Alloy:

  • High strength and durability: Ideal for use in aircraft components, lightweight engineering structures, and automotive parts.
  • Lightweight: Easy to move and reduces the burden on users.
  • Corrosion-resistant: Long-lasting use, even in diverse weather conditions.

    • Precision Manufacturing Process

    Before becoming a complete wheelchair, MATSUNAGA’s structure undergoes a series of meticulous processes, including:

  • Seamless, edge-free frame forming
  • High-precision welding
  • Surface treatment to further enhance the strength of the aluminum alloy

    • Designed for Maximum Safety and Usability

    MATSUNAGA’s decision to use Grade 7 aluminum alloy stems from a commitment to provide the highest quality for users. The result is a wheelchair structure that is:

  • Strong and durable, supporting a maximum weight of 100–130 kilograms
  • Lightweight and easy to transport
  • Backed by a 5-year structural warranty

    • If you’re looking for a wheelchair that combines durability, lightness, and safety in one, MATSUNAGA is the name you can trust.
