High-precision customized structural and functional profiles manufactured under strict ISO 9001:2015 standards.
In the contemporary industrial ecosystem, aluminum extrusions stand as the foundational infrastructure for lightweighting, structural optimization, and thermal efficiency. China's manufacturing landscape, led by specialized clusters in Foshan City, Guangdong, accounts for the world’s most advanced and highly scaled production facilities. Sourcing custom aluminum profiles is no longer just a transaction based on cost per metric ton; it is a complex, co-engineering paradigm that integrates metallurgy, structural load simulations, advanced tooling technologies, and strict global certifications such as GB/T19001-2016 / ISO9001:2015.
This white paper details the capabilities of LvXing Intelligent Equipment Co., Ltd. alongside its premium raw material partner, Fenglu Aluminum. It explores how modern engineering teams convert complex geometries, ranging from multi-hollow subway screen doors to high-strength helipads, into high-performance, real-world assets.
"By utilizing premium Fenglu Aluminum raw materials and operations with heavy-tonnage extrusion presses ranging from 800T to 20,000T, Lvxing processes critical alloys spanning the 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series. This enables the fabrication of massive structural elements measuring up to 1.2 meters in width and 28 meters in length."
The chemical composition and thermal treatment of aluminum alloys dictate their final mechanical attributes. Selecting the appropriate alloy series is a crucial stage in engineering custom profiles:
| Alloy Series | Key Elements | Mechanical Traits & Strengths | Primary Target Applications |
|---|---|---|---|
| 1xxx Series | Pure Al (≥99.0%) | Excellent conductivity, high corrosion resistance, high ductility | Busbars, electrical transformers, chemistry equipment |
| 2xxx Series | Copper (Cu) | Ultra-high strength-to-weight, critical fatigue resistance | Aerospace structures, military defense equipment |
| 3xxx Series | Manganese (Mn) | Moderate strength, highly workable, excellent weatherability | Heat exchangers, general fabrication, HVAC components |
| 5xxx Series | Magnesium (Mg) | High tensile strength, superb marine corrosion resistance | Ship decks, marine infrastructure, structural fuel tanks |
| 6xxx Series | Silicon & Mg | Exceptional extrudability, highly responsive to heat-treatments (T5/T6) | Helipads, architectural frames, solar mounting tracks |
| 7xxx Series | Zinc (Zn) | Highest yield strength, exceptional structural toughness | Aircraft primary structures, aerospace landing gear |
Lvxing's capability is backed by the prestigious "Special Aluminium Materials for Aerospace" Certificate. This ensures that every process step, from chemical composition validation of billets to extrusion speed controls and cryogenic testing, meets high-performance engineering standards.
Foshan City, located in China’s Guangdong province, is recognized as a global capital for aluminum extrusion. The competitive advantages of sourcing from this hub include:
Direct access to premier raw materials like Fenglu Aluminum. Downstream processes, such as chemical polishing, hard anodizing, and multi-axis CNC machining, are located nearby, reducing logistical delays and handling damage.
Operating press lines from 800T up to 20,000T enables the fabrication of diverse profile types. This scale allows Lvxing to manufacture large, single-piece extrusions that eliminate structural welds, thereby increasing mechanical integrity.
Lvxing's engineering team analyzes client CAD models to identify potential manufacturing issues, such as uneven wall thickness, sharp corners, or extrusion flow bottlenecks, before tooling creation.
By utilizing premium Fenglu Aluminum raw materials, Lvxing ensures that every extrusion profile meets strict international standards. Operating with press lines up to 20,000T, they produce alloys including the 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series. They fabricate fully shaped products with cross-sectional widths up to 1.2 meters and lengths up to 28 meters, designed for demanding industrial applications.
Custom aluminum extrusions are key components in modern infrastructure and industrial engineering. Below are the primary application areas:
Helipads deployed on offshore oil rigs, hospital roofs, or naval vessels must withstand dynamic structural loads, wind shear, and corrosive marine conditions. Marine-grade 6005A-T6 or 6082-T6 profiles provide high structural strength and resistance to saltwater corrosion. Standardizing the structural plank designs allows for weld-free interlocking assemblies that distribute structural landing loads evenly across the deck.
Metropolitan rapid transit systems require components with high dimensional stability and long cycles of continuous operation. Transit system screen doors require precise tolerances to prevent mechanical wear and jam-ups. Additionally, utilizing lightweight aluminum structural shapes in train frame components reduces overall rolling mass, contributing to lower energy usage.
Heavy manufacturing facilities, high-traffic commercial portals, and high-voltage electrical enclosures require durable hinge systems. Extruded continuous geared hinges distribute load across the full height of the door, minimizing stress on structural framing and eliminating the sag associated with traditional butt hinges.
Lvxing's engineering team brings 15 years of technical experience. This background helps identify design issues early, allowing the team to offer practical suggestions that help turn conceptual designs into functional products.

Understanding the cost structure of custom aluminum extrusions is key to optimizing procurement budgets. Sourcing models in China are calculated using a structured pricing formula:
Total Sourcing Price = [Aluminium Ingot Base Price (SMM/LME) + Processing/Extrusion Premium] + Tooling Amortization Cost + Surface Finishing Cost + Precision CNC Machining Fees + Outer Export Packing & Ocean Freight
Key pricing variables include:
High-durability structural solutions engineered for specialized industrial and transportation environments.
