CNC Machining Aerospace Grade Aluminum Extrusion Profiles

Foshan Pailian Aluminium Ltd is one of the most reliable manufacturers and suppliers of cnc machining aerospace grade aluminum extrusion profiles in China. Welcome to wholesale cheap cnc machining aerospace grade aluminum extrusion profiles made in China here from our factory. We also accept customized orders.

At Zhonglian Aluminum, we specialize in CNC Machining Aerospace Grade Aluminum Extrusion Profiles that deliver uncompromising strength, precision, and reliability. As a 33-year-old, one-stop aluminum solution factory with 50,000 tons annual capacity, we combine in-house tooling, extrusion, surface finishing, and 5,000 sqm high-precision CNC machining to bring your designs to life. Our profiles are engineered from 6063 and 7075 aerospace-grade alloys, meeting the most stringent industry standards for critical applications.

Our 20,000-ton extrusion presses unlock possibilities for super large cross-section aluminum profiles, addressing the unmet needs of high-stakes sectors including:​

• Aerospace & Aviation (structural components, aircraft frames)​
• Heavy Industry (large equipment bases, industrial machinery frames)​
• Renewable Energy (wind turbine hubs, solar tracker supports)​
• Rail Transit (high-speed rail car bodies, train structural parts)​
• Shipbuilding (marine-grade structural components)​
• Large-Scale Industrial Equipment (heavy-duty machine frames, conveyor systems)​

This unique production capacity eliminates the limitations of standard extrusion, allowing us to manufacture oversized profiles that balance exceptional strength, structural stability, and dimensional accuracy-even for the most complex geometries.

Our CNC Machining Aerospace Grade Aluminum Extrusion Profiles are trusted for:

• Aerospace & Aviation: Aircraft landing gear components, wing supports, and fuselage frames.
• Industrial Automation: Robot arms, heavy-duty machine frames, and conveyor system structures.
• Renewable Energy: Solar panel mounting brackets and wind turbine components.
• Transportation: High-speed rail car bodies and electric vehicle chassis frames.
• Defense & Military: Radar antenna structures and armored vehicle components.

The foundation of any high‑precision aluminum profile is a high‑quality extrusion die. Our in‑house tooling department handles the entire die development process, ensuring accuracy and reducing lead times.

• Professional engineering team creates die designs based on your drawings or samples

• Advanced CNC and EDM machines produce durable, high‑precision dies

• Die testing and calibration ensure optimal flow and dimensional accuracy

Why it matters: In‑house die making means better communication, faster adjustments, and higher precision for your custom profiles.

With 25 extrusion lines and 50,000 tons annual capacity, we can handle projects of any scale with consistent quality.

• High‑grade aluminum alloys (6063, 6061, 7075, etc.)

• Precision billet heating to 480–520°C

• Hydraulic extrusion presses from 500 to 2800 tons

• Continuous cooling system for stable structure

• Automatic sawing to lengths up to 12 meters with ±0.1mm tolerance

Why it matters: Our extrusion expertise ensures uniform wall thickness, straightness, and excellent surface quality.

Surface treatment enhances durability, corrosion resistance, and appearance. We offer a complete range of in‑house finishing options.

• Anodizing (clear, black, silver, custom colors)

• Powder coating (over 100 RAL colors)

• Electrostatic coating (E‑coating) for superior corrosion protection

• Brushing, polishing, and wood grain finishes

• Salt spray testing and adhesion testing for quality assurance

Why it matters: Proper surface treatment extends product life and ensures your profiles look great in any environment.

Our 5,000 sqm CNC machining center is equipped with multi‑axis machines to deliver precise, ready‑to‑assemble components.

• CNC milling, drilling, tapping, and cutting

• Precision tolerance as tight as ±0.05mm

• Custom machining according to your CAD/3D drawings

• Large‑scale machining capability for long profiles

• Deburring and cleaning for a finished product

Why it matters: In‑house CNC machining reduces lead times, improves accuracy, and ensures your parts are ready for assembly.

Quality is built into every stage of our process.

• IQC incoming material inspection

• IPQC during extrusion and machining

• FQC final inspection before shipment

• Dimensional measurement, hardness testing, and surface inspection

• Full traceability for every order

Why it matters: Our strict QC ensures you receive products that meet or exceed your expectations.

We protect your profiles during transit to ensure they arrive in perfect condition.

• PE film wrapping

• Foam protection for delicate profiles

• Wooden crate or pallet packing

• Steel banding for stability

• Global shipping with reliable logistics partners

Why it matters: Professional packaging minimizes damage and ensures on‑time delivery.

• ISO 9001, CE, TUV, SGS, RoHS Certified: Our processes and products meet international quality and safety standards.
• In-House Testing: We conduct hardness, tensile strength, and corrosion resistance tests to ensure every profile meets your requirements.
• 33 Years of Expertise: Our team's decades of extrusion and machining experience ensures consistent, high-quality results.
