In aluminium trading, profit margins and customer satisfaction depend on one thing above all: a reliable, efficient and technically capable extrusion partner. It is crucial to ensure that every aluminium extrusion order meets specifications, delivery timelines and market standards.
As a trader, your brand reputation is on the line with every shipment. Before you close a deal or place an order, use this checklist to qualify aluminium extrusion suppliers.
1. What Are Your Extrusion Capabilities?
Start with the fundamentals. If the supplier can’t produce the profiles your customers need, the rest is irrelevant.
Ask about:
- Press capacity and maximum billet size
- Profile size range (especially maximum circumscribing circle diameter - CCD)
- Alloy grades available (6063, 6005A, 6061, 6082, etc.)
- Minimum achievable wall thickness
- Complexity of shapes they can extrude
- Die development process for new/custom extrusion profiles
Why it matters: You need to match client specifications fast. Having a supplier with limited tooling or shape capabilities can delay your projects or cost you contracts.
2. Can You Share Tolerance Standards and Quality Certifications?
For industrial clients like automotive, architectural or aerospace, tolerances and consistency aren’t optional.
Ask for:
- Compliance with EN 755-9, ASTM B221 or other global standards
- ISO 9001, IATF 16949 or sector-specific certifications
- Internal quality checks, test intervals and rejection rates
Why it matters: These metrics protect you from rejections, rework costs and lost credibility. Verified quality systems also help you close deals with premium buyers.
3. What Surface Finishing Options Do You Offer?
Finishing impacts both function and market value. Depending on your end-use markets, you may need specific coatings or treatments.
Ask about:
- Anodising (type, thickness, colour range)
- Powder coating
- Mechanical finishes (brushed, polished)
- Special coatings for marine or architectural use
Confirm if finishing is in-house or outsourced. This affects lead time, quality control and cost.
4. What Is the Typical Lead Time for Tooling and Production?
Speed and flexibility are critical for traders managing multiple markets. It is important to know about:
- Tooling development time for new dies
- Standard production lead time
- Minimum order quantity (MOQ)
- Stock availability for fast-moving profiles
If your business model relies on quick turnarounds, avoid suppliers with long tooling timelines or inflexible batch sizes. Check out various building and construction extrusion products listed on our platform to compare lead times from different aluminium extrusion suppliers globally.
5. What Are Your Packaging and Logistics Capabilities?
Packaging errors or poor logistics can erase your margins and destroy customer trust.
Ask about:
- Standard and custom packaging options (e.g., shrink-wrap, wooden crates, interleaved)
- Export readiness and handling of container loading
- Incoterms supported (FOB, CIF, DDP)
- Experience with international documentation and customs procedures
Why it matters: Reliable export logistics reduce damage claims, customs delays and handling costs on your end.
6. How Do You Handle Custom Profiles and R&D Support?
In B2B trading, competitive edge often comes from being able to offer custom, client-specific solutions. Here are a few things you can confirm with the seller:
- Can they work with CAD files and simulate designs before die creation?
- Will they support prototype development?
- Do they provide technical consultation on alloys, temper or design feasibility?
Why it matters: Responsive suppliers with technical support for custom extrusions can speed up development cycles, helping you win deals faster.
7. What Is Your Pricing Model and Payment Flexibility?
Lastly, understanding the cost structure helps avoid hidden fees.
Ask for:
- Price breakdowns (raw material vs. value-added services)
- How prices change with order size or finish type
- Whether they offer credit terms or price locks on long-term contracts
- Currency options for international deals
Why it matters: Transparent pricing helps you plan margins accurately and avoid disputes. Payment terms can improve your cash flow strategy.
