Foshan’s Nanhai district is the largest aluminum processing base in China, producing aluminum profiles, extrusions, and fabricated products for construction, industrial, and consumer applications worldwide. For buyers sourcing aluminum windows, doors, curtain walls, decorative profiles, or structural components, Foshan provides access to hundreds of specialized manufacturers with advanced production technology.
The Scale of Foshan’s Aluminum Sector
Nanhai’s Dali and Guicheng towns host the core of Foshan’s aluminum industry, with over 200 major aluminum extrusion and fabrication companies. The region’s combined annual aluminum processing capacity exceeds several million tons. Major Chinese aluminum brands including Nanshan, Fenglu, Weiye, and Xingfa all have significant operations in or near Foshan.
The product range covers architectural profiles (windows, doors, curtain wall systems), industrial profiles (machinery frames, conveyor systems, equipment housings), transportation profiles (bus and train interiors), and decorative applications (furniture frames, display systems, signage). Surface treatments include anodizing, powder coating, wood grain transfer, PVDF coating, and electrophoresis.
Why Foshan for Aluminum Products
Several factors make Foshan the preferred sourcing destination for aluminum products. The concentration of producers creates intense competition that keeps prices competitive. Proximity to raw aluminum suppliers in Guangdong province reduces material costs. The availability of skilled workers and specialized equipment enables complex custom profiles. And the well developed logistics infrastructure connects Foshan factories to international ports efficiently.
Selecting an Aluminum Supplier
When choosing among Foshan’s many aluminum producers, focus on these criteria. First, verify their extrusion press capacity. The tonnage of their extrusion presses determines what profile sizes and wall thicknesses they can produce. A factory with presses ranging from 600 to 3600 tons can handle most standard and custom profiles.
Second, assess their die making capability. The quality of extrusion dies directly impacts profile accuracy and surface quality. Factories with in house die workshops generally offer better control over profile dimensions and faster development of custom dies.
Third, evaluate their surface treatment facilities. A factory that handles anodizing, powder coating, or wood grain finishing in house can offer better quality control and shorter lead times than one that outsources these processes.
Custom Profile Development
One of the advantages of sourcing aluminum from Foshan is the ability to develop custom profiles economically. The process starts with your technical drawing or sample. The factory’s engineering team reviews the design for manufacturability, proposes any modifications to improve extrusion efficiency, and produces a die. Die costs typically range from $200 to $1,500 depending on profile complexity and size.
First samples are usually available within 7 to 10 days after die completion. Once samples are approved, bulk production can begin. Lead times for standard orders range from 15 to 25 days, though large orders or complex specifications may require longer.
Quality Standards and Testing
International buyers should specify the quality standards their aluminum products must meet. Common standards include GB/T 5237 (Chinese national standard), EN 755 (European standard), ASTM B221 (American standard), and AS 1866 (Australian standard). Key quality parameters include alloy grade (6063-T5 and 6061-T6 are most common for architectural applications), dimensional tolerance, surface quality, and mechanical properties such as tensile strength and hardness.
Reputable Foshan factories perform in house testing including spectrometry for alloy composition, tensile testing for mechanical properties, salt spray testing for corrosion resistance, and thickness measurement for surface coatings. Request test certificates with each shipment to verify compliance with your specifications.
Pricing and Payment
Aluminum pricing is tied to the London Metal Exchange (LME) aluminum price plus a fabrication premium that covers extrusion, surface treatment, packaging, and profit margin. Foshan fabrication premiums are competitive globally, typically ranging from $800 to $2,500 per ton above LME depending on the complexity of the profile and surface finish.
Payment terms commonly offered by Foshan aluminum factories include 30% deposit with order confirmation and 70% balance before shipment. Established relationships may qualify for more favorable terms. Always use secure payment methods and consider using a sourcing agent to verify production progress before releasing final payment.
