Enquire NowAs a premier supplier in the modern metalworking space, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. (located in Jimo District, Qingdao, China) has established itself as a leading manufacturer of custom aluminum frame profiles and precision industrial components. Since our formal establishment in 2022, we have focused on providing advanced extrusion, fabrication, and surface treatment capabilities to meet demanding application specifications worldwide.
Operating from an expansive 200-mu industrial production site, our modern infrastructure includes 80,000 square meters of manufacturing facilities and a 4,000-square-meter administrative headquarters. Our primary manufacturing footprint features five advanced extrusion lines (including specialized 2500T, 1450T, 1150T, and 700T extruders), enabling a production capacity of 15,000 tons annually. Backed by a team of over 90 metalworking specialists, we design, fabricate, and test complex profiles for rail transit, aerospace, automotive, marine, structural building, and industrial automation assemblies.
To guarantee compatibility with international quality and safety expectations, our production lines adhere to strict quality management programs. We maintain a comprehensive set of global manufacturing certifications:
Automotive-grade quality assurance system governing raw material tracking, production tolerances, and structural consistency.
Environmental management compliance focusing on low-emission processing, energy efficiency, and material recycling.
Railway application standards and certified structural welding control systems for critical rolling stock elements.
International welding and adhesive bonding approvals for safety-critical industrial assemblies.
Our strategic manufacturing location in the coastal city of Qingdao, China, provides distinct logistic and supply chain efficiencies for international B2B buyers. The Yellow Sea trade corridor connects our production lines directly with major shipping lanes to North America, South Korea, Japan, Europe, and Southeast Asia.
By integrating regional billet supply chains with deep-water port access, we minimize overland transport costs and optimize container scheduling. Despite fluctuating international trade conditions, Kangjian maintains a stable 30% average annual growth rate in order delivery volume. This growth reflects our consistent product quality, pricing stability, and reliable logistics support for global markets.
Choosing the correct alloy and temper is critical to meeting structural requirements. For window frames, structural systems, and precision components, the 6000-series (Al-Mg-Si) alloys are the industry standard due to their balance of extrudability, weldability, corrosion resistance, and heat-treat response.
Alloy 6063 is widely used for architectural windows, doors, and decorative frames. Containing Magnesium (0.45-0.9%) and Silicon (0.2-0.6%), it features high extrudability, allowing for complex geometries with thin walls. When processed to a T5 or T6 temper, it provides sufficient yield strength (up to 170 MPa) while maintaining excellent responsiveness to anodizing, powder coating, and PVDF liquid painting.
For load-bearing structures, heavy-duty machinery frames, and robotic arm parts, Alloy 6061 is preferred. Formulated with Magnesium (0.8-1.2%) and Silicon (0.4-0.8%), plus trace Copper and Chromium, it delivers high tensile strength (up to 310 MPa in T6 temper). Alloy 6061-T6 provides the structural integrity, fatigue resistance, and shear capability needed for dynamic load environments.
| Alloy & Temper | Tensile Strength (min) | Yield Strength (min) | Elongation (min) | Primary Application Scenarios |
|---|---|---|---|---|
| 6063-T5 | 150 MPa (22 ksi) | 110 MPa (16 ksi) | 8% | Architectural windows, LED light tracks, shower frames |
| 6063-T6 | 205 MPa (30 ksi) | 170 MPa (25 ksi) | 8% | Structural window walls, solar framing systems |
| 6061-T6 | 290 MPa (42 ksi) | 240 MPa (35 ksi) | 10% | Heavy machinery frames, robotics kits, transport beams |
| 6082-T6 | 310 MPa (45 ksi) | 260 MPa (38) ksi | 10% | High-stress structural parts, marine frame engineering |
Global B2B procurement demands strict adherence to local regulations and technical standards. In North America, structural extrusions must meet ASTM B221 standards, while European markets require CE markings and compliance with EN 755 and EN 12020 specifications.
To meet these requirements, Kangjian implements a complete trace-control system throughout production. We track alloy composition, extrusion temperatures, cooling rates, and aging processes. Mechanical properties are verified through tensile testing, Rockwell hardness checks, and dimensional audits to ensure compliance with customer drawings.
For surface treatments, we offer anodized finishes that meet AAMA 611 standards for corrosion protection, as well as powder coating options that comply with Qualicoat Class 1 & 2 and AAMA 2604/2605 specifications for UV resistance and longevity in outdoor environments.
Aluminum extrusions are widely used across diverse sectors due to their strength-to-weight ratio, design flexibility, and ease of recycling. Our products serve several key industrial markets:
Modular T-slot and V-slot profiles for machine bases, safety enclosures, linear motion guides, and heavy-duty conveyor systems.
Lightweight structural components, EV battery tray frames, bumper beams, and decorative trim designed to support vehicle weight reduction.
Corrosion-resistant, powder-coated frameworks for commercial outdoor furniture, pergolas, and architectural shading systems.
Thermally-broken window and door profiles, curtain wall frames, and structural facades engineered to improve building energy efficiency.
Anodized, clean-room compatible framing components for medical device mounts, scanner assemblies, and ward partitions.
Heavy-duty structural framing, cable tray ladders, and panel profiles for subways, railway rolling stock, and shipping containers.
The aluminum industry is shifting toward lower carbon footprints and increased material circularity. As global buyers establish stricter Scope 3 carbon emission targets, the demand for primary aluminum with low carbon footprints and post-consumer recycled alloys is growing.
To support these sustainability goals, our production facility focuses on maximizing internal scrap recovery, optimizing thermal efficiency on our extrusion lines, and utilizing recyclable billet materials. By implementing advanced tooling design and temperature-controlled extrusion, we reduce waste, lower energy consumption per ton, and maintain high surface finish quality.
Additionally, our investments in multi-axis CNC machining centers allow us to deliver fully-fabricated, ready-to-assemble profiles directly to industrial customers. This one-stop manufacturing approach simplifies global supply chains, reduces total shipping weight, and eliminates the need for secondary local processing.
Whether supplying corrosion-resistant structural assemblies for maritime installations, lightweight components for rolling stock, or high-precision industrial frames, our engineering team collaborates with customers from design review to final delivery. This cooperative approach helps optimize profile geometries, improve structural performance, and reduce overall project costs.
Providing value to industrial buyers requires offering a comprehensive suite of metalworking capabilities under one roof. Our modern machinery handles the entire manufacturing process:
Our tooling department designs and manufactures customized dies using computer-aided modeling, ensuring precise dimensions and surface quality for complex profile configurations.
Equipped with high-precision CNC machining centers, we perform complex milling, drilling, tapping, and pocketing tasks, holding tight tolerances for assembly-ready parts.
Our surface treatment options include clear and color anodizing, organic powder coating, chemical cleaning, and mechanical brushing, ensuring long-term durability and corrosion resistance.
Our engineering team continuously updates our processes to align with changing B2B market demands. We implement advanced process controls, optimize extrusion speeds, and utilize finite element analysis (FEA) to verify the performance of custom profile geometries prior to die production.
This systematic approach minimizes trial runs, shortens lead times, and ensures that critical dimensions conform to engineering specifications, helping keep customer projects on schedule.
