Selecting the right material is not simply a matter of cost. Different materials vary significantly in strength, weight, corrosion resistance, and maintenance costs. Using the wrong material in an unsuitable environment may lead to structural deformation, corrosion, increased maintenance costs, and even safety hazards. In this article, we will introduce 8 common material types used for carts and help you make a more informed decision based on your specific application needs.
Types of Cart Materials
Currently, the main materials used to make carts are steel, aluminum alloy, and high-strength plastics.These materials have significant advantages in terms of strength, durability, cost, and applicable scenarios, making them the mainstream choice in the industry.
Carbon Steel
Stainless Steel
Aluminum Alloy
PP
HDPE
Composite Materials
Plywood
Solid Wood
Material Comparison
| Material type | Main advantages | Main disadvantages |
| Carbon Steel | Low cost and high load-bearing capacity | Easy to rust |
| Stainless Steel | Rust-proof and easy to clean | higher cost |
| Aluminum Alloy | Lightweight, corrosion-resistant, and easy to transport | Cost higher than steel |
| PP | Lightweight and chemically resistant | medium intensity |
| HDPE | Impact resistant and waterproof | Average load bearing |
| Composite Material | Customizable performance | higher cost |
| Plywood | low price | Easily deformed by moisture |
| Solid Wood | Environmentally friendly, reparable | Heavy and easily worn |
How to Choose Different Cart Materials
- Load Capacity
Load capacity is one of the most critical factors when selecting cart materials. Different materials vary significantly in strength and structural performance:
Light-duty (under 150 kg): Aluminum alloy or high-strength plastics are suitable.
Medium-duty (150–300 kg): Powder-coated steel or reinforced/thickened aluminum alloy is recommended.
Heavy-duty (over 300 kg): High-strength steel or full steel structures are preferred.
If high load requirements are paired with insufficiently strong materials, long-term use may result in deformation, cracked weld joints, or even structural failure.
- Weight Control
The weight of the cart itself directly affects:
Ease of manual operation
Battery endurance for electric stair climbing carts
Shipping and export logistics costs
For equipment that needs frequent movement or stair climbing, lightweight construction is especially important. This is why aluminum alloy is widely used in high-end electric carts.
- Corrosion Resistance
Whether the cart will be used in humid conditions or exposed to water or chemicals directly impacts material selection.
Standard indoor environments: Powder-coated steel is usually sufficient.
Humid or outdoor environments: Aluminum alloy or stainless steel is recommended.
Food and medical industries: Stainless steel is preferred.
Coastal or high-salt environments: High-grade stainless steel is required.
Insufficient corrosion resistance can lead to rust, which not only affects appearance but also reduces structural strength.
- Usage Frequency
Will the cart be used occasionally or on a daily, high-frequency basis? This is a key consideration.
High-frequency use: High-strength steel or reinforced structures are recommended.
Moderate frequency: Powder-coated steel or reinforced aluminum alloy.
Low frequency: Standard aluminum alloy or plastic materials are sufficient.
Under high-frequency conditions, fatigue resistance becomes particularly important.
- Operating Environment
Different environments require different material properties:
Construction sites: High impact resistance is required — choose high-strength steel.
Warehousing and logistics: Wear-resistant and corrosion-resistant — choose powder-coated steel.
Medical environments: Easy to clean and antibacterial — choose stainless steel.
Cold storage facilities: Low-temperature resistant — choose HDPE or stainless steel.
Environmental factors are often overlooked compared to load capacity, but they directly influence product lifespan.
- Budget Considerations
Material costs generally rank as follows:
Lower cost: Carbon steel
Cost-effective: Powder-coated steel
Mid-to-high range: Aluminum alloy
Premium: Stainless steel and composite materials
Material selection should be matched to budget while ensuring safety and performance requirements are met.
- Appearance and Brand Positioning
Material choice also influences product appearance and market positioning:
Stainless steel: High-end and professional
Aluminum alloy: Lightweight and modern, high-tech appeal
Powder-coated steel: Industrial style
Plastic: Lightweight and economical
Material selection is often an important part of brand image and product positioning.
Conclusion
High-strength steel continues to be the primary material for heavy-duty industrial carts due to its exceptional load-bearing capacity and structural durability. However, as the demand for lightweight and portable material handling equipment grows, aluminum alloy carts and high-performance plastic carts are becoming increasingly popular.It is recommended that material selection be based on a comprehensive evaluation of load-bearing requirements, operating environment, budget, and product positioning to achieve the optimal balance between performance and cost.
