Advanced Surface Treatment Technologies

We provide comprehensive surface finishing solutions to meet diverse architectural requirements, ensuring superior weather resistance, color stability, and flawless textures:

  • Anodizing: Industrial-grade treatment providing excellent corrosion and wear resistance.
  • Electrophoretic: Delivers a smooth, uniform coating with enhanced weather resistance and bright finishes.
  • Powder Coating: Offers a wide range of colors and robust protection against impact and environmental elements.
  • PVDF Coating: High-performance fluorocarbon finish ensuring extreme durability and long-lasting color retention in harsh climates.
  • Wood Grain Transfer: High-end aesthetic finish combining aluminum strength with luxurious natural wood textures.

Every finishing line is strictly controlled to guarantee exceptional aesthetic versatility and long-term structural protection for custom aluminum applications.

Frequently Asked Questions

Everything you need to know about our custom aluminum extrusion and manufacturing services.

What is your typical MOQ (Minimum Order Quantity)?
For standard aluminum profiles, our MOQ is 500 kgs per order. For custom deep-processing and extrusion molds, the MOQ can be discussed flexibly based on your specific project trial scale.
What aluminum alloy grades do you primarily use?
We mainly produce aluminum profiles using high-quality alloys, primarily 6063, 6061, 6005, and 6082, which offer excellent structural strength, corrosion resistance, and machinability.
What surface treatments and finishes are available?
We offer comprehensive finishes including Mill Finish, Anodizing (clear, bronze, black), Powder Coating (all RAL colors), Electrophoresis, Wood Grain transfer, and PVDF coatings.
How long does it take to develop a new custom extrusion mold?
Normally, custom mold design and fabrication takes about 10 to 15 days. Once the mold is approved and samples are tested, mass production usually takes another 7 to 10 days.
Do you provide CNC deep processing and fabrication services?
Yes, our facility is fully equipped with advanced CNC machining centers, precision cutting, punching, milling, drilling, and tapping to deliver ready-to-assemble components.
Can you provide free product samples for quality testing?
Yes, we can provide short-length profile samples free of charge. Clients are typically responsible for international courier shipping costs, which can be refunded upon placing an official bulk order.
What are your standard production and delivery lead times?
On average, our standard lead times range from 2 to 6 weeks, depending on the profile complexity, required surface finish, and total order volume.
Who owns the tooling/extrusion die after purchase?
You own the custom tooling since you pay for its development fee. We maintain and store the dies securely in-house at no extra cost for your future repeat orders.
What quality control and inspection standards do you follow?
Every profile undergoes strict quality checks, including dimensional measurements using CMM/calipers, visual checks, and mechanical testing to meet international standards.
How do you pack the profiles to prevent shipping damage?
We use robust export-standard packaging, including EPE pearl cotton wrapping, shrink film protection, strong kraft paper, or custom wooden crates for international container shipping.
