Engineered for Los Angeles and global commercial structural applications
Southern California is a global hub for architectural innovation, industrial design, and green building technology. Los Angeles has established some of the most rigorous building standards in the world, including the California Energy Code (Title 24) and strict seismic construction frameworks. Meeting these demands requires structural components that offer exceptional weight-to-strength ratios, energy efficiency, and superior corrosion resistance.
Aluminum profiles are the backbone of modern building systems in Los Angeles. From high-rise curtain walls in Downtown LA to sustainable residential framing in coastal Santa Monica, the demand for precision-extruded 6063 and 6061 alloys is growing rapidly. Our solutions are designed to address key local priorities, including thermal performance, structural longevity, and aesthetic excellence under intense Pacific coastal exposure.
Our structural aluminum profiles undergo rigorous testing to ensure compatibility with seismic damping systems, complying with California ASCE 7 structural design guidelines.
Coastal marine environments in Southern California require highly durable finishes. We offer ASCA-compliant powder coating and heavy-duty anodized finishes to resist salt mist and UV degradation.
Our custom thermal break designs reduce thermal conductivity, helping architects optimize U-factors to meet strict Title 24 insulation requirements.
Bridging Chinese manufacturing excellence with North American logistical demands
To support major real estate developments and infrastructure projects in Los Angeles, developers and industrial manufacturers need a reliable supply chain. Our manufacturing facilities are equipped to handle high-volume demands while meeting precise technical tolerances.
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. is a leading manufacturer specializing in high-performance aluminum extrusions. Operating from an expansive 200-mu industrial park (covering 80,000 square meters of production space), we manage 5 advanced extrusion lines, including a 2500T heavy extruder and several 1450T and 1150T systems. With an annual capacity of 15,000 tons of high-grade profiles, we ensure consistent supply and competitive pricing for the US market.
Our certifications reflect our commitment to global quality and safety standards, including ISO 9001, ISO 14001, IATF 16949 (Automotive), EN 15085/ISO 3834 (Welding), and DIN 6701 (Bonding systems).

Supporting diverse architectural, industrial, and infrastructure designs
Our precision extrusions are optimized for curtain walls, thermal-break windows, and storefront frames. These systems resist ocean air and meet the thermal performance required for high-rise commercial structures across LA.
To support California's renewable energy goals, we manufacture high-strength photovoltaic (PV) brackets and frames. These lightweight components resist corrosion and provide long-term stability for utility-scale solar installations.
We supply lightweight, high-performance profiles for rail, marine, and automotive transport. Our profiles are used in heavy-duty shipping containers, commercial trailer beds, and transit systems serving the Port of Los Angeles.
Founded in Jimo District, Qingdao, in 2022, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. was established to meet the global demand for advanced extrusion profiles. Located near a major international shipping port, our facility serves both local markets and high-demand international markets, including South Korea, Japan, the United States, and Europe.
Our founders established the company to close the supply gap for precision structural extrusions. Today, our products are used in demanding applications, including Nordic harbor cranes, subways, auto parts, and energy-efficient building systems. Our rapid growth (averaging 30% annual increases in order delivery) highlights our commitment to engineering quality and supply chain reliability.
With state-of-the-art tooling, advanced alloy testing labs, and strict quality control, we ensure our profiles meet the specifications of demanding commercial and industrial projects.

Answering common structural engineering and procurement questions for the LA and global markets
Structural profiles, such as those made from 6061-T6 alloy, are engineered to provide high tensile and yield strength while remaining lightweight. This reduces the total mass of building envelopes and curtain walls, lowering inertial forces during seismic activity. Additionally, we support custom slotting for flexible gasket joints to accommodate building movement.
For projects within 5 miles of the Pacific coast, we recommend a Class I anodized finish (minimum 18-micron or 0.7-mil thickness) or an AAMA 2605-compliant powder coating. This prevents pitting and filiform corrosion caused by salt air and marine moisture.
Tooling development and sample confirmation take 7 to 10 days. Mass production takes 15 to 20 days, followed by ocean transit from Qingdao to the Port of Los Angeles or Long Beach, which typically takes 18 to 22 days. We coordinate with shipping partners to ensure timely customs clearance and delivery.
Thermal breaks insert a low-conductivity polyamide barrier between the inner and outer aluminum frames of windows or doors. This minimizes thermal bridging, helping builders meet the strict heat gain/loss limits required by California Title 24.
