Strengths:




Weaknesses:
Lower heat resistance compared to metal rims (not ideal for high temperature applications).
Lower max load capacity than PU on Aluminium Rim wheels in extreme conditions.
Ideal Applications:
1. Factory carts & trolleys
2. Medical equipment
3. Lightweight material handling
4. Food & beverage industry (non marking PU available)

Extremely durable
Aluminium rim provides superior structural integrity.

Higher load capacity
Ideal for heavier medium duty applications.

Better heat dissipation
Suitable for warmer environments.

Corrosion resistant
Performs well in humid or wet conditions.
Weaknesses:
Heavier than nylon rims – May add weight to equipment.
Higher cost – Aluminium rims are more expensive than nylon.
Ideal Applications:
Heavy duty industrial trolleys
Automotive assembly lines
Machinery movers
Aerospace & logistics equipment
