Aluminum Profiles: Types, Uses, and How to Source from China
Aluminum profiles are versatile structural components used across industries for their lightweight durability and customization potential. This guide covers everything from material specifications to smart sourcing strategies for international buyers.
How to Find Reliable Aluminum Profiles from China in 2025
With China producing 57% of global aluminum output (IAI 2023), these strategies ensure quality procurement:
- Verify certifications: Look for ISO 9001, SGS, and specific alloy certifications like EN AW-6063
- Request mill test reports for material composition verification
- Use Alibaba Trade Assurance for payment protection on platforms like Alibaba.com
- Check production capacity - reliable suppliers typically maintain 5,000+ metric tons/month
What Buyers Should Know Before Buying Aluminum Profiles from China
Critical considerations when importing:
| Factor | Details |
|---|---|
| MOQ | Typically 1-3 tons for standard profiles |
| Lead Time | 15-30 days for customized orders |
| Shipping | FOB prices 20-30% lower than domestic suppliers |
Types of Aluminum Profiles
Standard (T-slot, angle, channel)
Custom extruded
Functions and features of Aluminum Profiles
Key advantages driving global demand:
- Corrosion resistance: Natural oxide layer prevents rust
- Strength-to-weight ratio: 1/3 the weight of steel with comparable strength
- Thermal conductivity: Ideal for heat dissipation applications
Scenarios of Aluminum Profiles
Common applications with real-world examples:
- Construction: Curtain walls at Shanghai Tower used 12,000 tons of profiles
- Electronics: iPhone frames use 6000-series aluminum
- Transportation: Tesla Model 3 contains 410 lbs of aluminum components
How to Choose Aluminum Profiles
Selection matrix based on application needs:
