Zhonglian Aluminum: 33 Years Of Deep Diving in Custom Aluminum Extrusion, Setting A Benchmark For Global One-Stop Solutions

[Foshan, China, March 7, 2026] As a leading enterprise in China's aluminum profile industry, Guangdong Zhonglian Aluminum Co., Ltd. (Zhonglian Aluminum) has built a full-chain service system from mold development, alloy customization, precision extrusion to CNC deep processing, relying on 33 years of professional experience and taking "custom aluminum profiles" as its core competitiveness. Serving customers in more than 80 countries and regions worldwide, the company provides highly adaptable solutions and has established itself as a reliable supplier benchmark in diverse fields such as industrial manufacturing, architectural decoration, automotive, and aerospace.​

Currently, the global custom aluminum extrusion market is growing at an annual rate of 8%, with manufacturing industries increasingly demanding higher material precision and functional integration. Zhonglian Aluminum has accurately grasped industry trends and built an industry-leading full-series alloy customization capability, covering 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, 7xxx and other full-series aluminum alloy materials. It can match the optimal formula according to customer needs - from high-purity conductive 1xxx series, ultra-high-strength 7xxx aerospace-grade alloys, to corrosion-resistant 5xxx marine-grade materials, and versatile 6xxx industrial-grade alloys, realizing full coverage from ordinary civil use to high-end precision scenarios.​

"Our customization is not limited to material selection, but also extends to in-depth adaptation of structure, size and function," said the Technical Director of Zhonglian Aluminum. The company can realize custom extrusion from simple special-shaped cross-sections to complex multi-cavity structures according to customers' 2D/3D drawings. The profile length ranges from 0.5m to 12m, the wall thickness precision is controlled within 0.8mm-12mm, and the dimensional deviation is ≤0.1mm, meeting the strict requirements of automatic equipment, auto parts, building curtain walls and other different scenarios. For example, the 6063 grade sunroof guide rail profiles customized for new energy vehicle customers have successfully achieved a weight reduction of 12kg and a driving range increase of 3%; the high-precision track profiles developed for automated machinery customers have reduced equipment failure rate by 40%.​

Behind the customization capability is Zhonglian Aluminum's strong full-industry chain layout. The company owns a 100,000 ㎡ production base, equipped with 25 advanced extrusion production lines and 10+ high-precision Haas/FANUC CNC machining centers, building a one-stop production system of "mold development - aluminum billet melting - extrusion forming - surface treatment - CNC deep processing - finished product assembly". All core processes are independently controllable, avoiding precision deviations and cycle delays caused by intermediate links.​

In key process links, Zhonglian Aluminum has established strict precision control standards: the aluminum billet heating temperature is accurately controlled at 480-520℃, and the extrusion speed reaches 15m/min to ensure the stability of profile forming; the CNC deep processing precision can reach ±0.02mm, supporting complex processes such as 3-axis/4-axis/5-axis milling, drilling, and bending, realizing one-step completion from profile to finished part; the surface treatment link provides diversified solutions such as anodizing, powder coating, PVDF coating, and wood grain transfer. Among them, the anodized film thickness is adjustable from 8-50μm, the powder coating salt spray test can reach 1000 hours without corrosion, and the color uniformity ΔE ≤1.5, balancing durability and aesthetics.​

Relying on an annual production capacity of 50,000 tons and an intelligent scheduling system, Zhonglian Aluminum has shortened the custom product development cycle to 7-15 days and the bulk delivery cycle to within 20 days, 30% faster than the industry average. It realizes flexible switching between small-batch trial production and large-scale mass production, meeting customers' rapid iteration needs.​

With stable custom quality and efficient services, Zhonglian Aluminum has become a long-term partner of many well-known enterprises worldwide. Its customers cover eight major fields including industrial automation, construction engineering, automobile manufacturing, solar energy, and furniture decoration, including industry benchmark enterprises such as Siemens, Volkswagen, and JinkoSolar.​

"We customized more than 2,000 sets of anodized ceiling profiles for a European construction firm, which not only achieved precise adaptation of complex cross-sections, but also maintained no fading or deformation after 5 years of testing in a high-humidity environment," shared the Overseas Sales Director of Zhonglian Aluminum. The customer has listed the company as a core supplier, and subsequent cooperation projects continue to expand. Another automated equipment customer from the United States commented: "The dimensional accuracy consistency of Zhonglian's custom profiles is extremely high, and the installation qualification rate after CNC processing reaches 99.8%, which greatly reduces our assembly costs."​

As an enterprise holding multiple international certifications such as ISO 9001, CE, TUV, and SGS, Zhonglian Aluminum has always strengthened its core competitiveness in customization through technological innovation. Currently, it owns 10 related patents, the mold development capacity can reach a service life of more than 100,000 times, and the material utilization rate is 17% higher than the industry average. In the future, the company will focus on emerging fields such as new energy, high-end manufacturing, and green buildings, further upgrade technologies such as 3D printing molds and intelligent testing, and promote custom aluminum profiles to develop in the direction of "lighter, stronger, and more environmentally friendly", creating greater value for global customers.​

Founded in 1993, Guangdong Zhonglian Aluminum Co., Ltd. (Zhonglian Aluminum) is a large-scale aluminum profile enterprise integrating R&D, design, production, and sales, with its headquarters located in Nanhai, Foshan. The company has a 100,000 ㎡ production base, 25 extrusion production lines, and a 5,000 ㎡ CNC deep processing center, with an annual production capacity of 50,000 tons. It specializes in providing full-series custom aluminum profiles and one-stop processing services, and its products are exported to more than 80 countries and regions around the world. It has won many honors such as "China Famous Brand" and "Guangdong Famous Product".​
