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

Our custom industrial heavy duty aluminum extrusion is engineered for high-load-bearing scenarios in industrial equipment, automation assembly lines, heavy machinery frames, and structural supports. Made from high-strength 6061 or 7075 aluminum alloy (or custom special alloys), it combines excellent mechanical properties, corrosion resistance, and machining adaptability. With 30+ years of experience in heavy-duty extrusion and 25 professional production lines, we offer CNC deep processing (high-precision milling, boring, etc.) and multi-type surface treatment (hard anodizing, powder coating, etc.) to meet complex industrial requirements. We can fully customize section size, wall thickness, deep processing, and surface finish according to your drawing requirements, ensuring the product meets the rigorous standards of industrial applications.

​

1. Section & Load Customization​

• Provide free mechanical simulation consultation (e.g., load-bearing test report) to ensure product stability in heavy-duty scenarios​

2. High-Strength Material Customization​

• Select 6061-T6/7075-T6 or special high-strength alloys according to working environment (e.g., high temperature, corrosion, high pressure)​
• Custom wall thickness design: thicken critical stress points to enhance load-bearing capacity without increasing unnecessary weight​

3. Industrial-Grade CNC Deep Processing Customization​

• Custom deep processing solutions: precision milling for complex surfaces, deep hole boring for hydraulic/pneumatic components, large-size thread tapping for assembly connections​
• Multi-axis CNC machining (3/4/5-axis optional) to meet complex structural design, reduce assembly steps and improve efficiency​
• Processing precision control: ±0.02mm for key positions, suitable for high-precision industrial equipment matching​

4. Targeted Surface Treatment Customization​

• Wear-resistant demand: Hard anodizing (20–50μm) with hardness ≥HV300, suitable for high-friction parts (e.g., guide rails, sliders)​
• Anti-corrosion demand: Powder coating + primer, salt spray resistance ≥1000 hours, adapt to outdoor/harsh industrial environments​
• Aesthetic demand: Brushed + anodizing, uniform texture, suitable for equipment appearance parts; custom color matching via RAL code​
