Aluminium section profiles are the backbone of modern structural design, clean energy technology, and transport architectures. As global industries strive toward carbon neutrality, the shift from traditional heavy steel configurations to light-weight, highly durable structural alloys has accelerated. The metallurgical properties of aluminium—possessing an optimal strength-to-weight ratio, intrinsic corrosion resistance, and superb thermal conductivity—render it indispensable for modern structural framing.
In the automotive domain, structural weight directly influences fuel efficiency and the battery range of electric vehicles (EVs). Custom aluminium extruded sections are utilized for structural motor housings, chassis components, crash boxes, and battery support enclosures. Concurrently, in renewable energy, solar installation frames demand weather-hardened profiles that withstand continuous high wind loads while minimizing structural dead weight. Achieving this requires robust manufacturing facilities with strict quality verification processes.
Global procurement entities source aluminium section profiles from China due to the unparalleled industrial clustering and supply chain consolidation. Chinese manufacturers don't just extrude raw metal; they operate within integrated ecosystems offering continuous manufacturing loops—from design optimization to tooling engineering, custom forging, high-pressure die casting, precision multi-axis CNC machining, and specialized electrochemical finishing.
The concentration of upstream smelters and specialized tooling workshops dramatically shortens lead times for custom dies. In addition, the highly integrated logistics network centered around deepwater ports like Ningbo-Zhoushan ensures seamless global shipping. Ningbo Jiangbei XinYe Metal Works Co., Ltd. capitalizes on this unique geographic and infrastructural advantage, providing high-precision custom fabrications that meet international technical standards.
A premier Chinese SME offering specialized OEM & ODM metal fabrication services since 1996.
Founded in 1996 as an owner-managed family enterprise, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has evolved into a highly specialized SME manufacturer of high-precision metal components.

Integrating heavy-duty forging, extrusion processing, and automated multi-axis finishing under one roof.
To guarantee structural compliance and precise tolerances, our production floors are equipped with specialized machinery imported from Japan and Europe.
Flexible Production Scalability: Our default operations run 6 days per week across 16 hours. However, to accommodate urgent bulk projects, we can expand our infrastructure to a 24/7 operating model within 30 days.
ISO 9001:2015 and SA8000 Certified Manufacturing Ensuring Traceability and Repeatable Quality.
At XinYe, quality is not a post-production check—it is integrated into every phase of manufacturing. From raw material spectrum validation to in-process dimensions and final component checkouts, we ensure complete traceability.
We leverage advanced metrological equipment within our temperature-controlled inspection laboratories. This allows us to deliver full compliance documentation, including dimensional reports, certificate of conformance (CoC), and raw material certificates for every production run.
Validates exact metallurgical alloy composition before extrusion or forging.
3D Coordinate Measuring Machine verifies tight micron-level dimensions.
High-resolution optical inspections for complex geometric profiles.
Secondary optical verification station for fast sample throughput inspection.
Measures micro-inch surface roughness to confirm post-anodizing parameters.
Evaluates load limits, structural integrity, and tensile strengths.
From technical blueprint evaluation to shipping, our process guarantees precision and repeatable results.
Customer submits detailed design specifications. Technical reviews verify draft feasibility.
Extrusion dies and molds are cut. Prototype samples are fabricated for verification.
Samples are shipped for customer testing. Technical adjustments are completed if required.
Mass production runs. Continuous inspection gates monitor tolerances.
Final metrology check, export-grade packaging, and container logistics.
In addition to forming metals, XinYe provides manual and automated mechanical assemblies within a dedicated dust-free workspace. Our one-stop assembly capabilities allow us to deliver structural sub-assemblies directly to our clients' final production lines.
Deploying high-precision profiles and castings in critical, high-stress environments.
Custom oil & gas explosion-proof enclosure housings and gas detection system components engineered using custom extrusion and multi-axis milling.
Lightweight structural components, connector sleeves, tube joiners, and brake levers developed for high-stress automotive environments.

Wood chipper cutter discs and feed roller assemblies designed using wear-resistant alloys (Q345B, 42CrMo, NM400).
To process custom extrusion profiles with complex design specifications, we utilize high-precision machines like the TIPAS h65TMY. This multi-axis machining center permits simultaneous drilling, turning, and profile milling inside a single chamber, eliminating positioning errors and maintaining tight tolerances across large-scale production runs.
This configuration allows us to execute complex profile machining, such as helical grooving, localized tapping, and asymmetrical slot milling, which are commonly required in aerospace fluid systems and automotive transmissions.
The structural profile manufacturing sector is experiencing significant changes driven by three technological shifts:
Sourcing structural metals across borders requires balancing production costs with lead-time predictability and quality consistency. Experienced procurement directors manage these variables through:
Common inquiries from procurement professionals, engineering teams, and supply chain partners.
Pricing is calculated based on current LME raw aluminum costs, profile complexity, tooling investment, post-processing steps (such as CNC machining), and surface treatments (like anodizing). We establish transparent pricing with our clients, updating quotes as market conditions change.
We require continuous MOQs for international orders to optimize production runs and extrusion setup processes. Specific quantities depend on the profile's weight per meter and alloy class. Please contact our technical sales team with your custom requirements.
Yes. We provide comprehensive documentation packages with every shipment. This includes Certificates of Analysis/Conformance (CoA/CoC), material spectral reports, detailed dimensional inspections, export custom clearance declarations, and Certificates of Origin.
Tooling fabrication and first-article prototype samples are completed in approximately 7 days. Mass production runs require 20 to 30 days after sample approval and receipt of the deposit. We establish firm production schedules to help clients manage inventory timelines.
We accept wire transfers (T/T), L/C structures, and secure electronic channels (Western Union, PayPal). Our standard terms are a 30% deposit in advance to secure metal billet stock and tool manufacturing, with the remaining 70% balance settled against copy of Bill of Lading (B/L).
We offer a comprehensive one-year warranty covering material purity and manufacturing defects. Our team reviews issues directly to support client satisfaction.
We utilize reinforced, export-grade packaging. Long-span profiles are bundled in protective layers and crated in heavy-duty wooden boxes. This helps protect surface finishes and maintains dimensional integrity during ocean transit.
We offer flexible freight options, including FOB Ningbo, CIF, and DDU. Shipping costs depend on packaging volume, weight, and the chosen transit method. We leverage our proximity to the Ningbo-Zhoushan port to secure competitive ocean freight rates.
