Choosing Materials for Medical Carts: Cleanability, Weight and Durability
1. Core Material Requirements in Medical Environments
· Compatibility with the intended cleaning and disinfection process
· Corrosion resistance
· Smooth, easy-to-clean surfaces
· Durability under repeated clinical use
2. Comparison of Common Cart Materials
|
Material
|
Typical Characteristics
|
|
Sheet steel
|
High strength and cost-effective; corrosion protection depends heavily on material grade and surface treatment
|
|
Stainless steel
|
Good corrosion resistance and cleanability; generally heavier and more expensive than aluminum
|
|
Aluminum alloy
|
Lightweight, corrosion-resistant and visually refined; typically higher material cost than basic steel
|
|
Engineering plastics
|
Lightweight and easy to clean; long-term performance depends on resin grade, load, chemicals and environment
|
3. NIM Medical Material Selection Approach
· Main structure: high-strength aluminum alloy for applicable product platforms
· Key load-bearing parts: selected steel or other engineered materials according to structural requirements
· Surface finish: coating or surface-treatment options selected according to project requirements
Material selection should balance cleanability, structural strength, corrosion resistance, appearance and cost.
