Products feature
Our custom aluminum profiles stand out for their precision, durability, and versatility, making them suitable for various high-demand industries:
✅ High Precision Extrusion: Equipped with 25 extrusion lines (ranging from 600T to 2500T), we achieve tight tolerance control (±0.05mm) for profiles of different shapes-including complex hollow, solid, and irregular designs.
✅ Superior Material Quality: We source 100% high-purity aluminum ingots (3003, 6061, 6063, 6082, 7075 series) to ensure excellent corrosion resistance, thermal conductivity, and mechanical strength.
✅ Flexible Size Range: From micro-profiles (0.5mm thickness) to large structural profiles (up to 500mm width), we accommodate custom dimensions to fit your specific project requirements.

Professional Surface Treatment for Custom Aluminum Profiles
We offer 8+ surface treatment options to enhance the appearance, durability, and functionality of your custom profiles-meeting both aesthetic and performance needs:
- Anodizing: Provides a hard, wear-resistant coating (5-25μm thickness) in natural silver, black, gold, or custom colors; ideal for outdoor applications (resists UV and rain).
- Powder Coating: Offers a smooth, scratch-resistant finish (60-120μm thickness) with RAL color matching; eco-friendly (zero VOC emissions) and suitable for indoor/outdoor use.
- Electrophoresis Coating: Delivers a uniform, glossy finish with high corrosion resistance; often used for high-end furniture and architectural profiles.
- Other Options: Brushing, polishing, sandblasting, wood grain transfer, and PVDF coating (for ultra-long lifespan-up to 20 years in outdoor settings).
End-to-End Customization Service: From Design to Delivery
As a one-stop custom aluminum profile factory, we simplify your procurement process with comprehensive services:
- Free Design & Mold Development: Our engineering team provides 2D/3D design support (using CAD, SolidWorks) and mold making (with fast turnaround-7-15 days for standard molds). We also offer mold modification services to optimize profile performance.
- Small-Batch & Mass Production Flexibility: Whether you need 50 pieces for prototyping or 50,000 pieces for mass production, we adjust our production schedule to meet your timeline (lead time: 5-20 days for standard orders).
- Custom Packaging & Logistics: We use moisture-proof kraft paper, bubble wrap, and wooden crates to protect profiles during shipping. Partnering with DHL, FedEx, and sea freight carriers, we offer door-to-door delivery to 120+ countries-with clear tracking and customs clearance support.
Advanced CNC Deep Processing for Precision Components
To meet your finished product needs, we integrate CNC deep processing into our services-eliminating the need for third-party suppliers and reducing your costs:
- CNC Machining Capabilities: Milling, drilling, tapping, cutting, and bending (with precision up to ±0.02mm) to create complex components (e.g., threaded holes, notches, curved profiles).
- Automated Production Lines: 10+ CNC machines (including 5-axis models) ensure consistent quality and high efficiency-even for intricate designs.
- Post-Processing Checks: Every processed component undergoes 100% dimensional inspection (using coordinate measuring machines, CMM) to ensure it meets your drawings.
Strict Quality Control: Certifications & Inspection Processes
Quality is our top priority-we adhere to global standards and implement strict quality checks at every production stage:
- Global Certifications: Our factory and products are certified by CE, TUV, SGS, RoHS, ISO 9001, ISO 14001, and KS-ensuring compliance with European, American, and Asian market requirements.
- 7-Step Quality Inspection:
a. Incoming material inspection (aluminum ingot purity test);
b. Extrusion process monitoring (temperature, speed, and pressure control);
c. Surface treatment quality check (coating thickness, adhesion test);
d. CNC processing dimensional inspection;
e. Mechanical property test (tensile strength, elongation);
f. Corrosion resistance test (salt spray test-up to 1000 hours);
g. Final visual inspection (no scratches, dents, or color defects).
- Quality Guarantee: We offer a 1-5 year warranty for custom aluminum profiles (depending on surface treatment and application) and provide replacement for defective products.
