Aluminum Extrusion Super-Large Industrial Profiles

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

At Zhonglian Aluminum, we're a 33-year-old, one-stop aluminum solution factory specializing in aluminum extrusion super-large industrial profiles. Our 100,000 sqm modern facility houses 25 extrusion lines, delivering an annual capacity of 50,000 tons. We manage every step in-house-from custom die design and extrusion to precision CNC machining and surface finishing-ensuring unmatched quality and efficiency for your most demanding industrial projects.

Our super-large profiles are engineered to deliver exceptional performance for heavy-duty applications, with capabilities that set us apart:

• Oversized Cross-Section Capacity: We produce profiles with cross-sections from 150x150mm up to 350x350mm, with custom sizes up to 1.15 meters wide and 10 meters long-ideal for structural frames and large equipment bases.
• Multi-Hollow Structural Design: The precision-engineered hollow structure maximizes rigidity while minimizing weight, ensuring stability and load-bearing strength for high-stress industrial environments.
• Aerospace-Grade Alloys: Available in 6063 (corrosion-resistant, aesthetic finish) and 7075 (T6 temper, extreme structural strength) alloys, our profiles meet aerospace standards for durability and reliability.
• In-House CNC Deep Processing: Our 5,000 sqm high-precision CNC machining center delivers ±0.05mm accuracy for pre-drilled holes, micro-sandblasted surfaces, and custom cutouts, so your parts arrive ready for assembly.
• One-Stop Production: From die design to finished components, we eliminate supply chain delays by handling every stage in-house, ensuring consistent quality and faster lead times.

Our aluminum extrusion super-large industrial profiles are trusted across critical sectors:

• Heavy Industry: Large machinery frames, conveyor system supports, and industrial equipment bases.
• Aerospace & Defense: Aircraft structural components, radar antenna frames, and armored vehicle parts.
• Rail Transit: High-speed rail car bodies, metro vehicle structural sections, and track supports.
• Renewable Energy: Wind turbine hubs, solar tracker frames, and energy storage system structures.
• Shipbuilding: Marine-grade hull frames, offshore platform components, and dock equipment.
• Infrastructure: Bridge supports, modular building frames, and large-scale construction structures.

We offer a full range of surface finishing options to enhance durability and aesthetics:

• Anodizing: Creates a hard, corrosion-resistant layer in clear, black, or custom colors for long-lasting performance.
• Powder Coating: Delivers a smooth, UV-resistant finish in over 100 RAL colors for outdoor and high-wear applications.
• Electrophoretic Coating (E-Coating): Provides superior corrosion protection (salt spray test >1000 hours) for marine and humid environments.
• Brushing & Wood Grain Transfer: Adds a premium aesthetic finish for architectural and consumer-facing projects.
• Fluorocarbon Spraying: Offers exceptional weather resistance for outdoor structural components.

We tailor every solution to your exact specifications:

• Custom Die Design & Manufacturing: Our in-house tooling team creates extrusion dies in 7–10 days, producing profiles that match your CAD/3D drawings perfectly.
• Precision CNC Machining: We handle complex operations like milling, drilling, and tapping for oversized profiles, ensuring a perfect fit for your assembly needs.
• Custom Cutting & Lengths: Profiles can be cut to lengths up to 12 meters, with precision cutting to minimize waste and reduce your on-site work.
• Rapid Prototyping: Get a CNC-machined prototype in 7–10 days to validate your design before full production.
• OEM/ODM Support: We collaborate with you from initial design to final delivery, ensuring your project meets all performance and aesthetic requirements.

Quality is built into every stage of our process:

• In-Process Inspections: IQC (incoming material checks), IPQC (production line monitoring), and FQC (final inspection) ensure dimensional accuracy and material integrity.
• Third-Party Certified: Our profiles and processes hold ISO 9001, CE, TUV, SGS, RoHS, and KS certifications, meeting international industrial and aerospace standards.
• 33 Years of Expertise: Our team's decades of experience in extrusion and machining guarantees consistent, reliable performance for every order.

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

• Protective Packaging: Profiles are wrapped in PE film, padded with foam, and secured in wooden crates or steel-banded pallets to prevent damage.
• Global Shipping: We partner with trusted freight providers to deliver worldwide, with guaranteed lead times and full shipment tracking.
• Ready to Ship: Standard profiles are in stock for immediate delivery, while custom orders are delivered within 12–15 days.

• One-Stop Solution: From die design to CNC machining, we handle every step in-house, reducing supply chain complexity and delays.
• 5,000 sqm CNC Machining Center: Our state-of-the-art facility ensures high precision and fast turnaround for oversized profiles.
• 33 Years of Experience: We're a trusted source for aluminum solutions with a proven track record of serving global industrial clients.
• Global Customer Praise: Clients in aerospace, automotive, and manufacturing consistently praise our on-time delivery, precision, and responsive support.
• Scalable Capacity: With 25 extrusion lines and 50,000 tons annual capacity, we handle both small batches and large-scale production runs.

Send us your CAD or 3D drawings, and we'll provide a detailed quote within 12 hours. Whether you need standard super-large profiles or a fully custom solution, our one-stop service ensures your project is delivered on time, on budget, and to the highest industrial standards.
